Most modelers will have heard about Alps decals, either because quite a few small aftermarket decal producers use Alps printers, or because of modelers who own an Alps or OKI printer. You don't need to own an Alps or OKI to create your own decals, because there are a number of custom printers that will do the printing for you. Therefore the Alps technology discussed in this article will be limited to what is required to design Alps/OKI decals. Designing decals likely requires learning some new software, but it is worth the investment: being able to design your own decals opens a world of new possibilities, and it's great fun. The printing costs are quite acceptable: an A4 or Letter size decal sheet containing only black and white decals cost me around 15-20 dollars. Full color artwork will cost more though, depending on the number of colors used.
This page describes the method that delivers the best possible results, and it's quite an involved process. It is not far removed from the 'professional' way of making decals, and may therefore be intimidating when viewed for the first time. I too would be intimidated if had seen this a couple of years ago. My advise is to start simple, perhaps in one or two colors only, and proceed slowly. I'm sure that the results will encourage you to take the next steps. If you want to quickly print some decals, this page is not the best starting point. There are simpler ways of printing decals with an Alps/OKI, for example directly from a text editor like Word, but they don't give the same quality and flexibility.
Without going too deep into the technical details, here are the main aspects that make an Alps (OKI) Micro-Dry printer different from other printers:
Alps Micro-Dry inks are some kind of wax, they will not dissolve in water like inkjet ink, and they are light-resistant.
lps has white ink, and this is of major importance for decals. Firstly because many decals have white in them, secondly because you can use white as a base-coat to make opaque color decals. Both arguments will possibly sound of little importance, but try to make color decals with an inkjet and we will talk again.
Most Alps color inks are not opaque, which allows one to print inks over each other and create new colors (see next chapter). Black, metallics and foils are opaque.
The Alps printer allows a lot of tricks, that make decal printing a possibility. For example, it can do spot color printing (using only one ink) instead of only printing tiny spots of cyan, magenta, yellow and black (dither printing) like all other printers do. Also, it is so accurate that you can do multiple printing passes on one sheet without alignment problems.
The resolution is basically 600 dpi. That is more than enough for decals printed in spot color mode: I have Alps-printed decals with readable text of 0.25 mm (1/100th of an inch) height ! With tricks you can make the 5000 model do 2400 dpi, which has some uses for dither printing.
Apart from cyan, magenta, yellow, black and white, there are also silver and gold plain metallics (which have sort of a satin finish) and silver and gold foil metallics (that look like chrome or gold plating).
Citizen, OKI, Kodak, Roland and Powis Parker sold their own versions of the Alps printers, all coming from the Alps production line. You can find a complete list of printer models in the reference section. All except the OKI MicroLine 7050c (Japan-only?) and the Kimosetter 410 are now discontinued (autumn 2012). The Japanese MD-5500 could be ordered until 31 May 2010 through Alps Supplies
Citizen, OKI, Kodak and Roland rebranded the (otherwise 100% identical) CMYK ink ribbons, and introduced new colors, which are mostly compatible across the models, expanding the color palette considerably. A complete list of ink cartridges can be found in the reference section.
Regarding the availability of the cartridges: Alps-USA will stop distributing them from early 2007 on. But Alps-Ireland and OKI-Europe will continue theirs, for at least a number of years. Therefore it is clear that cartridge production still continues at the Alps-Japan factory or its subcontractor. Alps Japan is obliged by law to sell supplies until 5 years after the end of production (31 May 2010).
Elephant's Rocket from Japan offers a repair service (MD-1000, MD-1300, MD-5000 and MD-5500 models) and sells second-hand refurbished printers (with either standard Japanese 100V AC, or a 220-240V AC transformer at extra cost). They also sell all Alps supplies including ink cartridges. They do business outside of Japan, and customer reports are very favorable.
In Germany, a repair service is reportedly offered by Ebay seller 'tesamanosa', located in Berlin.
The remainder of this page only gives information on designing decals, not how to use or operate an Alps printer. If you want to know everything about the Alps printer and how to print decals with it, subscribe to YahooGroups 'Alps' and 'Alpsdecal' mailing lists. Alternatively, you can search the mailing lists' archive built by Julian Bradfield which works much easier than Yahoo's search function. German speaking readers can check out the 'Microdry' forum at Druckeronkel.de.
There are many ways to design decals. The main choice is whether you want to use vector graphics or bitmap graphics. Every computer user will be familiar with bitmap graphics, since everyone uses Paint, Photoshop, Paint Shop Pro or something comparable to manipulate JPG, GIF, BMP, and dozens more file formats. When it comes to designing decal artwork with bitmap graphics, there are a number of problems. Bitmap software is primarily intended for the manipulation of bitmap images created with digital photography or scanning; making accurate drawings from scratch with bitmap graphics is not easy. Another factor is the resolution. To draw an A4 size decal sheet to be printed at 600 dpi, you need a giant 5000 x 7000 pixel file, and you must draw everything at the right size from the start.
Vector graphics are very different: objects are defined using vectors, not pixels. For example, a rectangle is defined by the (vector) position of its four corners. It also means they have no resolution, so it doesn't matter at all in which size you draw something. This may all sound complicated, but it works very naturally, a bit like a CAD program. However, it requires some adjustments if you're a bitmap person (ask me). It's impossible to explain everything about drawing with vector graphics. A vector graphics example is presented in the reference section.
The popular names in vector graphics are Adobe Illustrator and CorelDraw (free 30 day trial downloads are available of both), Microsoft Expression Design, and freeware/shareware software like Canvas and Inkscape. Also, you don't need the latest versions of the software packages mentioned, so it can be worthwhile to pick up an old version cheap. In designing decals you're using only the simple features, and an old version will most likely work just as well. I can say that now I know vector graphics, I never want to go back to bitmap for decals!
If you don't want to convert to vector graphics, the rest of the article will have limited value. Be sure to read David Aungst's article on designing decal artwork with bitmap graphics.
CorelDraw comes with 1000 fonts, that you can browse through using Font Navigator. Even with this very useful tool it is often quite a job to find the right font to recreate a 1:1 text. There are a lot of web sites with fonts, here are five:
These sites have powerful tools for determining a font type:
You can also use several fonts made especially for modelers:
USAF Amarillo and USN Longbeach fonts by TLai Enterprises (not for free)
Modern Luftwaffe font on request by e-mail
Simmers Paint Shop Forums - Font Downloads combining some of the above plus some additional ones
Even with all these fonts available, you will not always find what you are looking for. In that case you take the closest font, type the text, and change it to 'curves'. You can now manipulate the characters. Usually this is a lot of work, and it's not easy to keep the characters 'tidy', but it can be done. In fact, it is best to convert all your text to curves if you send it out for printing. Otherwise the printer person must have all your specific fonts installed (chances are very small). You can check whether you still have fonts in your CorelDraw artwork by checking 'Document Information' under the 'File' tab.
If you need squadron/wing/command badges for aircraft, look here:
USAF Media Gallery, an official site with dozens of logo in vector graphics (choose the EPS downloads if available)
Vektorgrafiken für Scalemodelle, a German site with lots of vector art for aircraft
If you need commercial logos, for race cars or trucks for example, have a feast on these sites:
Brands of the world, a Russian site with tens of thousands of logos in vector graphics
Logotheque, a French site with thousands of logos in vector graphics
Logotypes for professionals, a Latvian site with a few thousand of logos in vector graphics
Logotypes, a Russian site with around 5000 logos in vector graphics
Brandprofiles, a site with more than 170,000 logos
The logo artwork is not guaranteed to be accurate: it is contributed by people like you and me!
Note: you will need a trick to import EPS into CorelDraw. Don't import it straight as an EPS, but choose the 'PS, PRN, EPS - Postscript Interpreted'. Only then you will be able to see and manipulate the artwork.
Many modelers want to reprint existing decals, usually in a different scale than the original decals. Ignoring the touchy subject of copyrights for a moment, this can be done, but it is a lot of work! Just scanning them and push the 'Print' button results in a very mediocre quality. You will have to redraw everything if you want to achieve good (or even excellent) quality. An example is shown in the reference section.
The site of e-paint.co.uk is very useful to convert all kinds of paint standards to CMYK values. This includes FS595, RAL and BS381C. Whether an Alps can print that CMYK value without very obvious dithering is another question.
Like 99.9% of all color printers, the Alps printer will normally reproduce colors with dither / halftone / CMYK printing: by printing dots of cyan, magenta, yellow (CMY) and black (K for 'key'), an unlimited palette of colors is created. An exception are pure CMYK/RGB colors, discussed later. Since the Alps printer is 'only' 600 dpi, the dot pattern is visible and can be objectionable for decals, of course depending on the viewing distance. The following example was kindly supplied by Graeme Brown. It shows a decal 12 mm wide.
You can also use the spot color mode. In this mode, the printer uses only one ink cartridge at a time, instead of printing dots of CMY and black to make a color. Taking red as an example, if you print a solid layer of Y, and then a solid layer of M on top of it, the result is a solid red without dithering. A strong drawback is that the color palette is rather limited, as explained in the next section.
Important note: opinions on the use of the two printing methods vary considerably. Train modelers seems to avoid dither printing, since the dithering is too coarse for small trains (however one exception are graffiti decals). On the other hand, car modelers (1/24 or 1/25 scale) seem to find the dithering acceptable. As far as I know, no commercial Alps decals except those by Patto's are printed with dither printing.
The easiest way of printing with an Alps/OKI is the standard printing mode, which gives you dithered printwork. You don't split up the artwork or try to find the right color matches, you simply let the printer do the work for you, and accept the resulting dithering. Black, white and 'pure' CMY colors (see table in the next section) are printed solid, all others as dithered print. The standard settings are 600dpi horizontally and 85lpi vertically, but better resolution are also available (see next section). The visibility of the dither pattern depends on the colors and settings used. The standard printing method is the only method that allows photo-like images, or designs with color gradients to be printed. Examples are nose art on military aircraft and graffiti on trains. Dither printing is also one of the few options to print light (pastel) colors with an Alps/OKI.
The example below, kindly provided by the late Al Superczynski, shows part of the decals for a Le Mans Corvette pace car. It demonstrates the standard printing quality. In this example, black, white and yellow ('pure' CMY colors) are printed solid, the blue, green and red as dither print. The scan is also shown in 1:1 size, but the screen's limited resolution prevents you from seeing the fine dither pattern that would be visible in real life.

The MD-5000 has selectable halftoning values of 85, 145 and 190 lines per inch (lpi); other MD printers are only capable of 85 and 145 lpi halftones. Higher numbers give smoother looking halftoning colors. This is illustrated by three groups of objects printed at the indicated halftone values, kindly supplied by Peter Wisniewski. The first example below (on the left) shows solid colored objects. The second example (in the middle) shows rectangles with color gradients; green changing over to blue, and white shifting over to blue. It shows how the printer handles all the colors in those ranges. The third example (on the right) shows the result of printing high-resolution bitmap artwork for N scale carnival wagons, a herald of the Royal American Shows and a mural. When viewed with the naked eye, the 85 lpi printed images look terrible, the 145 lpi are a lot better and 190 lpi are quite smooth. In the 190 lpi print the halftoned colors look like they are solid, and the herald and the mural look pretty smooth. All these examples cannot be achieved by spot printing.
To get 190 lpi you need to do the following. Under 'media type' select 'VPhoto print media', that is the only way to 'unlock' the 190 lpi mode. The actual printing surface must be very smooth because the printer will make smaller print dots than usual. Under 'print mode' select 'VPphoto color' and under 'more settings' de-select the 'Glossy finish' and/or 'VPhoto primer'. A problem with 190 lpi printing is that a white undercoat (printed in spot color mode) does not align perfectly with the color inks printed in VPhoto mode. The further you go down a sheet, the larger the misaligment. It can be circumvented by printing the white undercoat as a separate decal.
If you define all colors in the artwork as 'pure' CMYK colors (see table below), the printer will automatically print them without dithering. An example is CMYK 100,0,100,0 which is 100% cyan, 0% magenta, 100% yellow and 0% black, giving green. Because the decals (usually) need a white undercoat, the artwork is first printed with 'White undercoat' selected in the printer driver. The same page is then printed with the 'Driver Colour Matching' option OFF. The printer then automatically sequentially prints four solid layers of CMYK ink, and not a dithered CMYK pattern. However, the white undercoat is only printed underneath the CMYK inks (avoiding partially translucent colors), and not where the pure white parts were defined in the artwork. Therefore, for decals with white parts, this method is not suited to prepare your artwork for the custom printer.
|Original artwork||Print white with|

Note: it appears that 'Driver Colour Matching ON / OFF' works differently on the various printers models and/or drivers. Taking pure cyan as an example, CMYK 100,0,0,0 with 'Driver Colour Matching' option off gives a solid layer of cyan on most printers, but with some it still results in a dithered print. However when the color is defined as RGB 0,255,255 (which is exactly identical since CMY and RGB are each others opposites), these printers print a solid layer of cyan.
|Spot Color||RGB (n/255)||RGB (n/100%)||CMYK (n/100%)|

To achieve decals with white parts, there is no way around splitting the artwork in two layers or pages. The first is a page with all the artwork (black parts can be excluded) copied and changed to black, which is then printed with the white ink cartridge. The second page/layer is a CMYK page, just as in the first example. The example shows that the decals are printed correctly, and therefore this method is suited to prepare your artwork for your custom printer, with a rather limited color palette. However, if you know how to split your artwork in layers or pages, why not use the method below and enjoy many more colors?

If you want more colors without dithering, you can use 'Spot color charts' (see below) to find out all colors available with the spot color overprinting mode. To start simple, the example used above is repeated here, but fully split up in layers/pages. The complete decal design is copied to pages representing W, C, M, Y and K, and then the parts that are not to be printed in that spot color are deleted. The remaining parts are then changed to black, so each spot color will be printed full strength (this is a difference with 'normal' color separation in the printing business, where greyscale values are used). This manual color separation may look complicated, and indeed it requires some getting used too, but after that it's pretty easy. This format is preferred by most custom printers.

Note: with some printers there is a problem with printing black over other colors. In the above example, that would mean leaving out the black parts in the white triangle of the 'Koni' decal.
In the second example a double pass with the Cyan ink is performed to make it more opaque, resulting in two hues of blue. There is no layer/page for the Black ink, since there is no black artwork.

Alternatively, you don't delete the unwanted parts, but change them to white. This can be an important technique if you have complicated artwork, for example designs with extrusions or shadows.
The Alps and OKI printers are basically designed to use CMY plus black and white inks. In the spot color mode, this gives you a fairly limited color palette, as shown below on the 'Alps and OKI Spot Color Chart' created by William Brillinger of Precision Design Co. and used with permission. The printing order is of limited importance, for example Y+M is tomato red, M+Y is a little darker red. Sometimes you will need a double layer of color. For example, a single pass of cyan will give a light blue color, and a double pass a middle blue color.
However, the red, green and blue (RGB) ink cartridges of the OKI-7000 printer can also be used in other Alps and OKI printers. It requires a trick with label swapping, but that's for the printer person to worry about. The combination of CMY and RGB gives a much larger color palette.
Here's another CMY + RGB palette, created by John Isherwood of Cambridge Custom Transfers and used with permission. An important difference with the previous two charts is that this chart was corrected so the on-screen colors match those of the actual printed colors. Still the color representation depends on your computer screen, and some report that they cannot match the color variety of this chart.
The palette can be expanded further by using 'OKI Opaque White' ink, which isn't opaque! By printing OKI Opaque White over colors, you can achieve pastels and greys. Technical note: on about half of the Alps and OKIs the white overcoat will not adhere. This can be solved by slightly increasing the print temperature, either by using a hair dryer or using a 'hotter' cartridge label. An alternative solution is printing your decal in the full-strength color and a copy in white, and layer the decals on the model.
Some rather complex receipies can be found in the color charts. An example is 'warm yellow'. Alps Yellow is a very bright yellow. By printing two layers of Alps White, one layer of Red (or alternatively Kodak Orange) and two layers of OKI Opaque White a slightly reddish base is achieved, and with one layer of Alps Yellow over this base a warm yellow is finally achieved .. An obvious drawback of complex color matching is that (in extreme cases) ten to twenty printing passes will be required for a sheet with multiple color decals. Of course this will increase the cost and the risk of errors.
Another problem of spot color matching is that it is often difficult to find an exact match of a specific color (for example RAF Sky for squadron codes, or a specific Federal Standard 595 grey color). On the other hand, many model manufacturers and even aftermarket decal producers don't always have accurate colors, so perhaps a reasonable match will do anyway.
John Peck of Precision Labels & Decals was not satisfied with the color representation of the above color charts, and created his own, in a very methodic way that was first tried by Eric Tetangco. They are shown here with permission.
John started by printing single and double layers colors, using a table format that shows every possible combination. Alps/OKI Cyan, Magenta and Yellow, OKI Red, Green and Blue and Kodak Process Orange and Process Green were used in the color table. John even printed a separate color table that uses the metallic inks as the first layer, creating several new colors. The adherence of certain layers can be pretty bad, notably when over printing Magenta or Red, or with any attempt to overlay with Process Orange. The use of Finish between passes made no difference. The problem differs between printers, possibly because the individual print head settings. The two layers table contains interesting information on the adhesion of the inks, since it is a diagonally mirrored arrangement. For example R1-C2 shows adhesion problems, whereas C1-R2 has no problems.
Also of importance is that the color chart was scanned, not photographed. This had an effect on the representation of metallics and particularly foils: due to their reflective natures, they almost never scan as seen. The particular scanner lights may cause fluorescence in any type of ink or underlying media which can distort colors in various unpredictable ways. One example is Process Orange over Process Green or vice-versa in the two layer chart; in reality it is an olive green, the scan shows an apple-like green.
Next was a set of tables showing the results of three layers. Each table is read as follows: start with the top row, then follow clockwise for the successive layers. The top and right rows are always identical, the bottom row keeps moving left one step with each of the eight tables. This results in a methodic analysis of all color combinations possible with three layers.
John even went so far as to create a four-layer table, using the same system. In this chart 'only' CMY and RGB are used, hence 6 times 6 makes 36 tables!
John overprinted the one, two and three layer color charts with one layer of OKI Opaque White.
Lastly, John photographed the complete color chart with his digital camera in natural light.
The full color chart can be ordered from Precision Labels & Decals. It's not cheap, but one must realise that printing a color chart is both time-consuming and quite costly regarding the inks. I believe it is a very good investment for anyone designing Alps decals.

Some items to discuss with your custom printer are: type of software and version used (CorelDraw, Illustrator, or perhaps PDF files), which ink-sets are used (always CMYK, but possibly RGB too, and just maybe Kodak orange and green), whether the printer can print two white layers on top of each other (not all printers can do this, yet you need two layers to make opaque white), whether black can be printed over other colors or not, and which decal paper is used (thickness etc), margins to be used in the artwork (at least 15 mm top and bottom, 5 mm left and right), whether the artwork should be put in separate pages, separate layers or even separate files. Most companies will also offer a decal design service. This is usually quite expensive, which is quite understandable if you look at the amount of work involved (see above!).

My very first Alps decals, a small and simple set in black, printed by Luca Beato.
It's impossible to explain everything about drawing with vector graphics. I've made one example showing a a basic design that would be a good learning exercise: a pre-war Luftwaffe iron cross. There are dozens of ways of designing things like this, and this is the method that I came up with. For the rest, follow the tutorials, use a book, or just dive in. As reported above, you don't need to know all the features, so keep it simple. Having a decal design you want to create helps a lot for motivation!
|1: The original German drawing had parts defined in fractions of 1/4, 1/8 and 1/32 of the overall dimension. Therefore I defined a 32x32 mm square as the basis of the iron cross, and 12x12, 8x8, 4x4 and 1x1 mm squares as drawing aids.||2: Set 'snap to objects' on, and move the 12x12 square to a corner of the large square. It will 'snap' in place. Then draw guidelines by 'pulling' them from the rulers, using the 'snap' feature to draw them exactly over the 12x12 square.||3: Move the 12x12 square to two other corners to draw two more guidelines. Also draw guidelines over the 32x32 mm square.|
|4: Take the 8x8 mm square to draw to more guidelines in the upper left corner left, again using the 'snap' feature.||5: Set 'snap to guidelines' on. Repeat the above with the 1x1 mm square.||6: Delete the 32x32 mm square. Plenty of guidelines now!|
|7: Draw the center black part of the iron cross, again using the 'snap' feature to make sure you're drawing an accurate cross.||8: After you reached the starting point, the object is 'closed' and can be assigned a fill color, black in this case. Set the outline to 'no outline', otherwise a hardly-visible black outline would remain and mess up the end result.||9: Using the same method, draw the white piece. Here you won't easily forget to delete the outline, because it is well visible.|
|10: Again with the same method, draw the thin black part.||11: You can now delete all the guidelines.||12: Copy and paste the two smaller parts, mirror them, and move them to the right.|
|13: Move the parts to the upper right corner. They will click in place because 'snap to objects' is still switched on.||14: Repeat the copy, paste, mirror and move action twice to finish the cross||15: The basic design is now finished. You can copy and paste it, and reduce or enlarge it to the desired size for the model.|
There is no simple way to scan and reprint existing decals, and achieve a good quality. A scanned decal sheet gives you a bitmap picture, not vector graphics. To convert a bitmap picture to vector graphics, you could use tracing programs like CorelTrace, but they don't give you simple and closed shapes that can be used for subsequent printing. In my experience, you will have to redraw everything manually - quite a lot of work, but the results can be better than the original.
Here's an example of how I do it. The first picture shows the scan of the car decal I wanted to reproduce. If you look closely you can see the ragged edges of the rather low-quality silkscreen printing. I imported the bitmap scan in CorelDraw, putting it in its own layer.
In another layer I drew a rough copy of the outline (shown deliberately outside the decal contour here). Then came the time-consuming part: moving the control points, deleting and adding points, and manipulating the Bezier handles of each control point. In my experience fewer control points give better results.
When that job was finally done, I drew another line over the color division of the decal. Lastly I drew the opening in the decal.
Next step was to copy the three lines, and paste them elsewhere on the sheet. I now had the basic design in vector graphics, as outlines.
The color division line was used to cut the overall shape in two pieces, and the opening was trimmed from the lower part. Finally, I gave the two pieces a color that matched the original decal, and selected 'no outline' to get rid of the black outline. Whether the two greens can be found in one of the palettes is another problem! One decal done..
A close-up shows the quality of the bitmap scan (left) compared to the vector design (right). Note that the design needs further fine-tuning, since the yellow-green stripe doesn't have a continuous taper.
If the scanned decal consists of text, you first try to find a font that is largely identical (CorelDraw has Font Navigator for this). Type the text, change it to 'curves', and manipulate the text as necessary.
A good example of decal redrawing is the Airfix F-4 decal sheet that Rob van Riel did. It is definitely a lot better than the original!
There's a confusing number of printer versions. This table lists the printers in chronological order, with their specifics. The Alps/Citizen/OKI list is largely based on information collected by Julian Bradfield. Kodak's First Check printer is roughly comparable with the OKI DP-7000, but it uses a different set of inks, and must have completely different drivers. Roland makes combined printer/cutters based on Alps technology, which use compatible wax ribbons and non-compatible resin ribbons. Additionally, Powis Parker sold a rebadged MD-5000 as the FoilFast printer, claiming it has its own unique print head, firmware and software. Kimoto sells a Kodak First Check equivalent (around 3000$). All except the OKI MicroLine 7050c (Japan-only?) and the Kimosetter 410 are now discontinued (autumn 2012).
|Alps||Citizen||OKI||Kodak||Roland||Powis Parker||Focus Digital Technoloy||Kimoto||Specifics|
|MD-2000S||Printiva 600C ?||-||-||-||-||-||-||Introduced 1995. Japan only. Supports standard colors and metallics.|
|MD-2010||Printiva 700||-||-||-||-||-||-||The basic model. Like MD-2000S. It doesn't recognise White cartridges.|
|MD-2300||-||-||-||-||-||-||-||Accepts Photo cartridges for Dye Sub printing. Doesn't recognise White cartridges.|
|MD-4000||Printiva 1700||-||-||-||-||-||-||Like 2010 but with a scanner head.|
|MD-1000||Printiva 600C ?||-||-||-||-||-||-||Introduced ~1997. 1200 x 600 dpi resolution in color printing. Supports White cartridges. Holds four cartridges. Printiva is white plastic.|
|MD-1500||-||-||-||-||-||-||-||Like 1000 but with a scanner head.|
|MD-1300||-||-||-||-||-||-||-||Like 1000 but accepts Photo cartridges for Dye Sub printing|
|-||-||Holds eight cartridges. Recognises White cartridges. Can print at 2400 x 600 dpi instead of 600 x 600 dpi by having variable size 600 dpi dots, in the VPhoto mode. This has no use when printing in the spot color mode, the main mode to print decals. It can be useful when printing bitmap artwork. Can print with Dye Sub(limation) if fitted with a special key, but Dye Sub is not suited for normal decals. MD-5000i is a Japan-only version with see-through case tops in either blueberry, grape, tangerine, lime, and strawberry. FoilFast is not a direct equivalent.|
|-||-||DP-5000s||-||-||-||-||-||Can print up to 1.35 meter long prints (e.g. banners). VPhoto is limited to 145 lpi (no option for VPhoto media) instead of 190 lpi as with DP-5000. Cannot do Dye Sub.|
|-||-||Introduced late 1999, Japan only. Sales ended 31 May 2010. USB instead of parallel connection. Supports long paper printing, 224 by 594 mm max. Recognises White and Opaque White cartridges, the latter only in back-print mode. FoilFast is not a direct equivalent.|
|-||-||-||-||-||-||MP-6000||-||Chinese production, possibly equivalent to MD-1300, see the printer specifications (MD-4800 was reported by the salesman, but that model never existed)|
|-||-||DP-7000||First Check||-||-||-||Kimosetter 410||Pre-press printer for professional use, expensive. Has room for nine cartridges. There are several more ink cartridges for OKI model (notably Spot Red, Blue and Green). The Kodak printer uses a rather different set of inks, and must have completely different drivers. The Kimosetter 410 does in essence behave like the Kodak, in as much as it requires the First Check driver and recognises cartridges with the Kodak bar codes|
|-||-||DP-7050c (Microline 7050c)||-||-||-||-||Probably an updated version of the DP-7000. Appears to be available in Japan only.|
|-||-||-||-||PC-12||-||-||-||Described as an Alps printer on steroids. Its mechanisms are almost identical, and the cartridges are identical in terms of size and shape. Holds nine cartridges. Also does cutting, probably leading to the name 'printer-cutter 12'.|
The basic inks for the Alps/OKI printers are Cyan, Magenta, Yellow and Black, but there is much, much more. The range of ink cartridges of five (or six if you include Powis Parker) different brands is confusing, and therefore I put together this table. The cartridges of all five brands are identical in function, and just re-branded. The Alps, Citizen and most OKI cartridges carry exactly the same labels, and work with no modification. The Kodak, Roland and Powis-Parker cartridges likely require re-labeling. The non-Dye Sub cartridges are sometimes called 'Standard'. Roland produces two types of cartridges: wax-based and resin-based. Only the wax-based inks are compatible (or likely identical) to Alps/OKI inks, and hence only these are listed. The Powis Parker cartridges work in at least the Alps MD-5000 after relabeling.
The DP-7000 colors Spot Red, Green and Blue are slightly different from red, green and blue mixes with Cyan, Magenta and Yellow. OKI Spot Red is paler than the red from Magenta plus Yellow, and with more yellow, giving an orange red. OKI Spot Green is a yellowish green, versus the blueish green of Y on C. OKI Spot Blue is a proper blue - no hint of purple as you get with Cyan plus Magenta - and again paler. Additionally, because red, green and blue are achieved with just one layer of ink and hence reduced opacity, new color mixes are possible.
The Kodak First Check cartridge range contains two unique cartridges: Process Green and Process Orange. Kodak Process Green is the same shade as green produced by Cyan and Yellow, except paler and around 50% of that opacity. The reduced opacity opens possibilities for new color mixes, such as shades around olive green when mixed with Process Orange. Process orange is a welcome color, since orange is impossible to mix from CMYK in spot color mode.
The silver and gold metallics have a satin finish, the silver and gold foil metallics look like chrome or gold plating. Another desciption is that silver foil looks like a polished piece of metal, while metallic silver looks like dull silver paint. The Metallics and Foil cartridges appear to have limited use for modeling purposes at first sight, but there are some. I've seen fastener / rivet decals printed with them. Model car emblems are another good application, especially when they are printed with four layers of ink. This gives it thickness, a 3-dimensional effect, so it looks like a real scale emblem, not a decal. They can also be used to create layered spot colors. Compared to Standard Cyan and Standard Magenta, Metallic Cyan and Metallic Magenta overprinted with Standard cartridges will result in slightly different colors, partly because they are opaque and because their colors are different. Foil inks, despite their glass-smooth appearance, can still be overprinted very well with Standard colors, resulting in shiny and foil-like colors.
The use of so many different inks can create problems with adhesion. It strongly appears that the individual printer settings play an important role here, so it is not very useful to report adhesion problems of specific colors. It also appears that with the ink thickness building up, the risk of scratching increases.
Modern Printing from Germany offers a cartridge refilling service, for Cyan, Magenta, Yellow and Black, plus Metallic Gold and Silver.
