Sublimation color problems are some of the most confusing issues you’ll face as a crafter. Your design looks perfect on screen, but then it prints in completely wrong colors – reds turn orange, greens come out blue, or everything just looks dull and washed out. The good news? Most of these problems have surprisingly simple fixes.

Color mismatches are the most frustrating part of getting started with sublimation. Your reds come out orange, your pastels look muddy, and you waste more blanks than you’d like to admit. But once you understand how ICC profiles and printer settings work together, everything clicks. This guide will save you that frustration with a complete color troubleshooting process.

Is This Normal? What Sublimation Ink Should Look Like

Before we start fixing things, let me save you some panic. Sublimation ink looks VERY different on paper than it does after pressing, and this is completely normal.

When you print a sublimation design, the colors on the paper will look dull, muted, and sometimes completely wrong. Green will look blue on the paper. Reds will look brownish. Skin tones will look grey. This is expected! Sublimation ink is designed to change color during the heat press process – the magic happens when the ink turns to gas at 380-400°F and bonds with the polyester fibers.

So how do you know if your colors are actually wrong? Press your print onto a test blank first. If the pressed result matches your screen (approximately – they’ll never be pixel-perfect), your colors are fine. If the pressed result still looks wrong, then you have a real sublimation color problem and should keep reading.

My tip: Keep a stack of cheap polyester fabric scraps just for test pressing. Before you commit a $5 blank, always test press on a $0.10 scrap first. This simple habit saves so much money!

Sublimation Color Problems: Diagnostic Table

This is my go-to reference when something looks off. Find what you’re seeing in the left column and follow the fix on the right.

What You See After Pressing	Most Likely Cause	Quick Fix
Red turns orange	Wrong ICC profile or pure red (RGB 255,0,0)	Install correct ICC profile; change red value to R:170-200
Green prints blue	Low yellow ink or no ICC profile	Check yellow ink level; install ICC profile for your ink brand
Black turns greenish	Not enough heat or time	Increase temperature by 5-10°F; add 15 seconds press time
Colors too dark	Designing in CMYK instead of RGB	Switch your design software to RGB color mode
Colors washed out/faded	Wrong paper side, moisture, or too much heat	Check paper orientation; pre-press blank; reduce time slightly
Blue turns purple	ICC profile mismatch	Update ICC profile or try a different one for your ink
Pink prints as red	Printer using wrong color profile	Disable Epson Color Management; select correct ICC
All colors dull/muddy	No ICC profile installed	Download and install the ICC profile for your ink brand
Colors have horizontal lines	Clogged print head nozzles	Run nozzle check, then 1-2 head cleaning cycles
One color completely missing	Empty ink tank or severely clogged nozzle	Refill ink; run multiple cleaning cycles

Save this table! Print it out and tape it next to your printer – it saves countless hours of guessing.

My 5-Step Color Fix Process

When you get sublimation color problems, work through these five steps in order. About 90% of the time, the issue is resolved by step 2.

Step 1: Run a Nozzle Check

Before anything else, make sure your printer is actually laying down ink properly. Go to your printer settings (on Epson printers: Maintenance tab → Nozzle Check) and print a test pattern. You should see clean, unbroken lines for all four colors – cyan, magenta, yellow, and black. If any lines are missing or broken, run 1-2 head cleaning cycles and check again. A clogged nozzle can make your colors look completely wrong because the printer is literally missing part of the color recipe.

Step 2: Check Your ICC Profile

This is the big one. An ICC profile is basically a translator between your computer and your printer – it tells your printer exactly how much of each ink to use for every color. Without the right ICC profile, your printer is just guessing, and it guesses wrong.

Every sublimation ink brand has its own ICC profile because each brand’s ink formula is slightly different. If you’re using Hiipoo ink with a profile made for Printers Jack ink, your colors will be off. Here’s where to find the right profile: check the product listing on Amazon where you bought your ink – most brands include a download link or a card in the box with a QR code. If you can’t find it, email the ink manufacturer directly. They always have profiles available.

My tip: Switching from generic ink to Hiipoo and installing their specific ICC profile makes a night and day difference. Colors go from “close enough” to actually matching your screen. This single change fixes most sublimation color problems.

Step 3: Verify Your Printer Settings

Even with the right ICC profile, wrong printer settings will mess up your colors. Here are the settings that matter most for Epson EcoTank and converted printers.

First, make sure you’re printing in RGB mode, not CMYK. Sublimation printers use CMYK inks, but your design files should be in RGB – the ICC profile handles the conversion. If you design in CMYK, the colors get converted twice and end up way too dark. In your design software (Photoshop, Canva, Cricut Design Space), check that your color mode is set to RGB.

Second, turn OFF “Epson Color Management” in your printer preferences. If both your ICC profile AND Epson’s built-in color management are trying to adjust colors at the same time, they’ll fight each other and your colors will be a mess. Go to Printer Properties → Color Management and set it to “Off” or “No Color Adjustment.” This is probably the most common beginner mistake.

Third, set your paper type to “Matte Paper” or “Presentation Paper Matte” in print settings. This tells the printer to use more ink, which gives you more vibrant sublimation results. Never use the “Plain Paper” setting for sublimation – it uses too little ink and your colors will always look faded.

Step 4: Print a Color Test Chart

After setting up your ICC profile and printer settings, print a simple color test chart and press it onto a polyester scrap. A good test chart includes solid blocks of red, blue, green, yellow, black, skin tones, and a gradient. Compare the pressed result to what you see on your monitor. The colors won’t be identical (monitors and prints are different technologies), but they should be close. If one specific color is still off, you may need to do some manual color correction in your printer driver settings – adjusting the individual color sliders by small amounts until the pressed result looks right.

Step 5: Check Your Heat Press Settings

Your heat press settings can also change how colors appear. Too much heat causes colors to shift – especially darker, brownish tones. Not enough heat leaves colors looking dull and faded. For most substrates, stick to 385-400°F for 45-60 seconds with medium pressure. Always verify your actual press temperature with an infrared thermometer, because the display can be off by 10-20 degrees.

Common Sublimation Color Problems (Detailed Fixes)

Red Turning Orange

This is probably the most common specific sublimation color problem I hear about. You design something with a beautiful red, and after pressing it comes out orange or salmon-colored. The reason is that pure red in RGB (255, 0, 0) is very hard for sublimation ink to reproduce accurately. The fix that works for most people is to install the correct ICC profile for your ink brand. But if your reds still look orange after that, try adjusting the red value in your design. Instead of using pure 255 red, try R:170-200, G:0, B:0. This tells the printer to use less red ink, which paradoxically produces a truer red after pressing. R:180 tends to give the best “true red” with Hiipoo ink on Epson EcoTank setups.

Sublimation Colors Too Dark

If everything you print looks darker than it should, the most common cause is designing in CMYK color mode instead of RGB. Open your design software and check the color mode – it should say RGB. If it says CMYK, that’s your problem. CMYK is meant for traditional printing presses, not sublimation. When your file is CMYK and your ICC profile tries to convert it again, you get double-converted colors that come out way too dark and oversaturated.

Another cause of too-dark colors is using the wrong paper type setting. If your printer is set to “Photo Paper Glossy” instead of “Matte Paper,” it may be laying down too much ink. Switch to the matte setting and you should see a noticeable improvement.

Why Are My Sublimation Colors Dull?

When your sublimation colors are dull or washed out, there are several possible causes. First, make sure you’re printing on the correct side of the sublimation paper – the coated side (brighter white, slightly tacky) should face the printable side. Second, pre-press your blank for 5-10 seconds to remove moisture, because moisture is the enemy of vibrant sublimation. Third, check that your print quality is set to “High” or “Best” in printer settings – “Draft” quality uses less ink and produces dull results.

If your sublimation is coming out dull even after checking all of those, or if your sublimation print looks faded no matter what you try, your ink might be old or low-quality. Sublimation ink can degrade over time, especially if exposed to light or extreme temperatures. Most ink should be used within 6-12 months of opening.

Black Turning Green or Brown

When black areas come out greenish or brownish instead of true black, it usually means not enough heat or not enough press time. Black requires all four ink colors (CMYK) to combine perfectly, and that needs adequate heat for the chemical process to complete. Try increasing your temperature by 5-10°F and adding 15 seconds of press time. If it’s still not right, check that all four of your nozzles are firing properly – a partially clogged nozzle can throw off the black color mix.

Colors Change After Pressing

You pressed your design and the colors looked great – but then they changed as the item cooled. This usually happens when the substrate retains too much heat and the ink continues to shift. The fix is simple: remove the transfer paper immediately after pressing (hot peel) and let the item cool in open air. Don’t stack hot items on top of each other or place them face-down, as trapped heat will continue to alter the colors.

ICC Profiles: The Simple Explanation

I know ICC profiles sound technical and intimidating, but think of it this way: your monitor speaks one “color language” and your printer speaks another. An ICC profile is the translator that makes sure they understand each other.

Without an ICC profile, your printer just makes its best guess at what colors to use – and for sublimation ink (which is different from regular ink), those guesses are usually wrong. That’s why people who never install an ICC profile always struggle with color accuracy.

Installing an ICC profile is actually easy. Download the profile file from your ink brand (it’s a .icc or .icm file), right-click it, and select “Install Profile.” Then in your printer settings, select it as the active color profile. Each ink brand has slightly different instructions, but they all include a guide with the profile download. Once it’s installed and selected, you’ll see an immediate improvement in color accuracy.

The most popular sublimation ink brands and their ICC profile availability: Hiipoo includes profiles via QR code in the box, Printers Jack has profiles on their website, and A-SUB provides profiles through their Amazon listing. If you bought generic no-name ink without an ICC profile, that might be your entire color problem – consider switching to a brand that provides one.

Printer Settings Cheat Sheet for Color Accuracy

Setting	Correct Value for Sublimation	Common Mistake
Color Mode (Design Software)	RGB	Using CMYK (colors too dark)
Paper Type	Matte Paper / Presentation Matte	Plain Paper (not enough ink)
Print Quality	High / Best	Draft (dull colors)
Epson Color Management	OFF / No Color Adjustment	Left ON (double color correction)
ICC Profile	Ink-brand specific profile	No profile or wrong brand profile
Mirror/Flip	ON (for text/images)	Doesn’t affect color, but common mix-up

Heat Press Settings and Color

Your heat press directly affects your final colors. Here’s what you need to know.

Too much heat (over 410°F) causes colors to shift darker and take on a brownish or yellowish tint. You’ll also see the substrate start to scorch. If your colors look “burnt,” reduce your temperature by 10-15°F.

Not enough heat (under 370°F) produces dull, faded colors because the ink hasn’t fully converted to gas. If your sublimation is faded, temperature is the first thing to check – use an infrared thermometer to verify your actual press temperature.

Too much time causes similar problems as too much heat – colors shift and substrates can yellow or scorch. Stick to the recommended times for your substrate and don’t walk away from your press.

For the most accurate colors, press at 385°F for 55 seconds on fabric and 400°F for 60 seconds on hard substrates. Always test on a scrap first, because every press runs a little differently.
