A Quick Note About AI-Generated Artwork for Plastic Card Printing

More and more customers are sending us designs created with AI tools — and honestly, a lot of them look fantastic. The problem is that AI image generators have no idea your design is going on a plastic card, so the files almost always arrive in the wrong format for print. Here's why, and what we do about it.

Why AI Artwork Usually Isn't Print-Ready

AI design tools are built for screens, not printing presses. That means the files they produce typically have three issues:


Wrong size and shape — AI tools generate square or arbitrary-sized images, not the precise dimensions of a credit-card-sized plastic card. We have to resize and reshape the design to fit, which can shift or crop important elements if we're not careful.


No bleed — Printed cards need extra artwork around the edges (called "bleed") that gets trimmed off during cutting. This guarantees there's no thin white line round the edge if the cut is a fraction of a millimetre out. AI-generated images are flat, finished pictures with nothing extra to give — there's no bleed to extend, so we have to create it artificially.


Wrong colour format (RGB instead of CMYK) — Screens display colour using RGB (red, green, blue light). Printing presses use CMYK (cyan, magenta, yellow, black ink). AI tools only ever output RGB. Converting to CMYK can shift colours noticeably — particularly with bright greens, vivid blues, and rich purples, which often look duller or different once converted.


The Trickiest Bit: Dark and Black Backgrounds
If your AI artwork has a black or very dark background, or a moody photo where the subject blends into shadow, that's the hardest type of file to convert. Pure black on screen (RGB 0,0,0) doesn't translate directly to pure black in CMYK printing of C0 M0 Y0 K100 — getting a rich, even black across a large background area takes careful adjustment, or you can end up with patchy, washed-out, or slightly brown-looking "black" once printed. Where a dark subject blends into a dark background, that blend can shift unevenly during conversion, sometimes losing definition that was visible on screen.

We can usually fix this, but it takes more time than a standard file, and on rare occasions a small amount of contrast or detail is lost in the process.

What We Do With Your Artwork

When your file comes in, we:
Resize and reshape it to the exact card dimensions and bleed requirements

Convert the colour profile from RGB to CMYK

Check and correct the resulting colours, especially in dark or black areas

Send you a proof showing exactly what will be printed, so there are no surprises

How You Can Help Us Help You

Send us the file as early as possible — colour correction on tricky artwork takes longer than a standard print-ready file.

Tell us if you're open to small adjustments — sometimes a slightly different background tone prints far more reliably than pure black

Always check your proof carefully — colours on your screen (RGB) will never look 100% identical to the printed card (CMYK); this is a limitation of print, not an error on our part

If in doubt, ask us first — we're happy to look at your AI-generated design before you finalise it and flag anything likely to cause printing issues

We're not precious about how a design gets made — AI, Photoshop, by hand, doesn't matter to us. We just want to make sure what ends up in your hand looks as close as possible to what you had in your head.

Frequently Asked Questions

Can I send AI generated artwork for plastic card printing?
Yes. We accept AI generated designs for plastic cards. The artwork usually needs resizing, bleed added and converting from RGB to CMYK before it is print ready, which we handle as part of preparing your file.


Why is AI generated artwork not print ready?
AI image tools are built for screens, not print. Files typically arrive the wrong size and shape for a card, with no bleed, and in RGB colour instead of the CMYK format needed for printing presses.


What is bleed and why does AI artwork not have it?
Bleed is extra artwork around the edge of a design that gets trimmed off during cutting, preventing a thin white line if the cut is slightly out. AI generated images are flat finished pictures with no extra edge content, so bleed has to be created artificially before printing.


Why do colours change when AI artwork is converted to CMYK?
Screens display colour in RGB, while printing presses use CMYK ink. AI tools only output RGB, and converting to CMYK can shift colours noticeably, particularly bright greens, vivid blues and rich purples, which can look duller once printed.


Why are black or dark backgrounds difficult to print from AI artwork?
Pure black on screen does not translate directly to pure black in CMYK printing. Getting an even black across a large background takes careful adjustment, otherwise it can print patchy, washed out or with a brown tinge. Dark subjects blending into dark backgrounds can also lose definition during conversion.


What do you do to make AI generated artwork print ready?
We resize and reshape the artwork to the exact card dimensions and bleed requirements, convert the colour profile from RGB to CMYK, check and correct the resulting colours especially in dark areas, then send a proof showing exactly what will be printed.


Will my printed card look exactly like my AI generated design on screen?
It will be close but not identical. Screen colours in RGB will never match printed colours in CMYK exactly, particularly with bright or dark tones. This is a limitation of print rather than an error in production, which is why we always send a proof first.


Can you check my AI generated design before I finalise it?
Yes. Send us your file as early as possible and we will look it over and flag anything likely to cause print issues, such as a pure black background or colours that may shift heavily during CMYK conversion, before you commit to a final order.
