Why Your Printed Colors Look Different: RGB vs. CMYK (and How To Check & Fix It)
Why Color Shift Happens in DTF Printing, Or Any Printing
We’ve all seen it — you design something bright and beautiful for your DTF transfers, but when it prints, the colors come out wrong. Maybe the red looks orange, or your vibrant purple turns blue. It’s frustrating and confusing — especially if you’re new to DTF printing.
Here’s the truth: most color problems in custom printing come down to one simple mismatch — your design is in RGB, but your printer uses CMYK. Unless your printer knows how to convert and simulate color accurately, your finished product will never match your screen.
What makes it more complicated is that this will differ from printer to printer or provider to provider depending on their ICC profile. Read on for more info and how to check what colors will actually be printed.
RGB vs. CMYK: What’s the Difference?
RGB: What You See on Screen
RGB stands for Red, Green, Blue — the light-based color model used by digital screens. It can display a wide range of colors, including very bright and vivid tones. But here’s the problem: RGB colors don’t exist in ink.
CMYK: What You See in Print
CMYK stands for Cyan, Magenta, Yellow, and Key (Black). It’s a subtractive color model that mixes inks to produce physical color. CMYK can’t match the vibrancy of RGB, which is why designs often look duller in print — unless your print shop knows how to handle it.
Top Reasons Your DTF Colors Shift
- RGB Files Sent Without Conversion: Many designs are created in RGB and never converted to CMYK before being printed. That’s a major reason for unexpected results in DTF printing. The printer or designer may or may not check the shift from RGB to CMYK required for the printer.
- No ICC Color Profile: An ICC profile is a file that tells your printer how to reproduce color accurately based on ink, film, and printer type. Without it, results are unpredictable.
- Designers and printers don't or can't preview CMYK Output: If you don’t preview your design in CMYK using the correct profile, you’re only seeing half the story. Many vibrant RGB tones aren’t printable at all.
How To Check It In Photoshop
Change mode to CMYK
Change color mode to CMYK
Check it using your color picker.
Open your color picker. See the warning triangle? That is telling you that color will not be printed in CMYK with the current profile. The box below it tells you the closest match that can be printed.
Choose the color in the box below the warning triangle to get a more accurate representation of what will be printed and to synch what you see on screen with what will be printed.
Applying an ICC profile to your project
Go to the edit menu. Near the bottom, you will see Assign Profile. This is where you can add an ICC profile. For the most accurate representation of color, ask your printer for their ICC profile or the one that they use and add it or select it.
Pint Habit uses the Japan Color 2001 Coated.
Now you will know with greater accuracy if the colors in your design will print properly with your provider and thier printer/profile or you can find the closest match.

Our advanced 8-channel printer lets us reproduce nearly 98% of the Pantone scale for vibrant, high-fidelity DTF transfers, DTF Prints, and our Wide Format Printing. Our wide format printers are already 8 color printers.
- Proper ICC Profile Matching: Every file is processed with an ICC profile that matches our exact printer, film, and inks — no guessing.
- Soft-Proofing and CMYK Simulation: We simulate your final color output before we print, giving an accurate preview proof and the chance to fix issues in advance.
Designing for Accurate Print: What You Can Do
Whether you’re working in Photoshop, Canva, or Illustrator — designing for DTF printing means starting with the end in mind. Here’s what we recommend:
- Switch to CMYK mode early in your design process or preview often
- Use an ICC profile (we can provide one)
- Know that neon, metallic, and high-vibrancy colors may not print exactly as they appear in RGB
- Ask for a soft proof or test print if color accuracy is critical
