Printed colours look different from your screen because a screen makes colour by shining light at you, while a print makes it with ink or dye that can only reflect the light falling on it, through fabric that absorbs and textures it. The shirt colour underneath, the print method and the buyer's own screen shift it further, so the realistic goal is a close, predictable match that your listing describes honestly, not a perfect one.
This guide is for print on demand sellers who have opened a sample and thought "that is not the orange I made", or who received a buyer message saying the same. Once you know where the shift comes from, you can design around it, choose the right file settings and set expectations before the order instead of apologizing after it.
Light from a screen, ink on a surface
A screen builds every colour by adding together red, green and blue light that the screen itself gives off. That lets it show colours that glow: electric blues, neon greens, hot pinks. Ink works the other way. It absorbs part of the light that reaches it and reflects the rest, so a printed colour can never be brighter than the light bouncing off the surface beneath it.
That is why the most saturated screen colours are the ones that move most in print. A neon green on your monitor has no ink equivalent on a cotton shirt, so it lands on the nearest colour the process can make, which reads duller.
The screen is not a fixed reference either. Phones, laptops and monitors differ in brightness and colour, night modes warm everything up, and your buyer looks at your mockup on their own device.
Colour profiles and file settings
Files carry a colour profile that tells software how to read their numbers. For listing photos, Etsy says "We convert images to use the sRGB color profile (CMYK color profile is for print only)" (Etsy image guide). For print files, at least one print on demand provider recommends "creating and uploading your final print files using the sRGB IEC61966-2.1 color profile", and warns that converting to CMYK before upload can "unnecessarily reduce the available color information" in an RGB-based print workflow (Printful colour profile guide).
The practical rule: design and export in sRGB unless your print partner asks for something else. Our article on RGB or CMYK for print on demand files covers the edge cases.
Fabric changes the colour
Paper is smooth and white. Fabric is neither. With DTG printing, the "ink absorbs into the fibers, so the print feels part of the shirt" (Printify on DTF vs DTG), and fibres that soak up ink also soften its colour and break up fine detail. DTF works differently: the design is printed on a film and heat-pressed on, leaving "a thin, smooth layer you can feel sitting on top of the fabric" (same source).
The blank itself is not one fixed colour either. Gildan's 5000 is 100% cotton in most colours but 50/50 cotton/polyester in heathers such as Dark Heather (Gildan 5000 spec sheet), and the speckled texture of a heather changes how a print reads. The spec sheet for the garment-dyed Comfort Colors 1717 says "Please allow for slight color variation in production and washing" and notes that "Special consideration must also be taken when printing white ink on garment-dyed cotton" (Comfort Colors 1717 spec sheet).
The garment colour under the print
On a light shirt, thin or light ink colours mix with the fabric colour, so the same design looks different on white, natural and pale yellow. On a dark shirt, coloured ink needs a white layer underneath or it disappears into the fabric. For DTG, dark garments need "a pretreatment coat and a white ink underbase" (Printify on DTF vs DTG), and Printful notes that on black or colourful garments a DTG print "may be less vibrant", with gradients "tricky to print" (Printful on DTG vs DTF). DTF transfers carry their own white ink layer, which is what lets them work on any fabric colour (Printify print methods).
Methods also differ on white itself. With sublimation, "the design becomes a part of the fabric" (Printify all-over print guide), and "The color white can't be printed on all-over print products" (Printful print method notes). The same Printful page says it does "not print white ink on white garments". We go deeper in printing on dark garments.
Where the shift comes from, and what to do
| Cause | What you will notice | What you can do |
|---|---|---|
| Light from the screen | Neon and very saturated colours print duller | Avoid designs that depend on neon, and test a sample |
| Colour profile | Colours shift after a conversion | Export in sRGB unless your partner asks otherwise |
| Fabric fibres and texture | Softer colour, fine detail breaks up on heathers | Use bolder shapes, thicker lines and fewer gradients |
| Garment colour | The same ink looks different on each shirt colour | Make a light and a dark version of the design |
| Print method | White, gradients and exact shades behave differently | Check your partner's guide for each method |
| Blank and dye batches | The shirt itself varies slightly | Mention it in the description |
Palette choice helps too. Colours with clear contrast survive every step better than subtle neighbouring tones, as our guide to choosing colour palettes for POD designs explains.
How to set buyer expectations
Etsy's listing guide says to "Describe the details of your item so buyers know what they're getting" (Etsy listing guide). For colour, that means three things.
Mockups that look like a print, not a glowing graphic. If your mockup is brighter than any shirt could be, the gap shows up as a disappointed buyer.
One plain line in the description saying colours can look slightly different between screens and on the printed item.
A sample of your best sellers, so you know how each colour really prints. Our checklist for ordering samples of your own products lists what to look at.
Honest photos also matter if a dispute happens. Etsy Purchase Protection covers a case where the item "matches the listing description and photos, but a buyer claims it does not", and it does not cover one where "The item doesn't match the listing description" (Etsy Purchase Protection).
How Alomations prepares files for print
Every design that comes out of Alomations is print-ready at 12 inches and 300 DPI (3,600 pixels on the long side), as a transparent PNG with an SVG alongside. One design produces light and dark versions, so it reads on white garments and on black. Tone rules per garment colour decide which version each colour gets, automatically, and you can override them.
The two versions are built for the problems above. A light variant turns lettering white even where it touches the drawing, so the words stay readable on a dark shirt, and a dark variant keeps painted art and line drawings readable. Our catalog products are printed with DTF for apparel, plus sublimation for products that need it. The light and dark versions guide shows when each one is used.
Frequently asked questions
Should I convert my design to CMYK before uploading?
Not unless your print partner asks for it. Etsy converts listing images to sRGB, and Printful recommends sRGB print files and warns that a CMYK conversion can reduce the colour information.
Why does my neon design look dull on the shirt?
Neon colours exist on screens because screens emit light. Ink on fabric can only reflect light, so the process prints the nearest colour it can make, which is less bright.
Will my design look the same on every shirt colour?
No. Light ink colours mix with light fabrics, and dark fabrics need a white layer under the ink. Separate light and dark versions keep the design readable across colours.
What should my listing say about colour?
A short, plain line that colours can vary slightly between screens and the finished item, backed by mockups that look like a real print.
