This is a partial list of common misconceptions about color management.


  1. Myth #1: Color Management is not useful in CMYK-only workflows
  2. Myth #2: There is some internal Lab/Color reference that the output of printers is compared to when profiling.
  3. Myth #3: The gamut of RGB is larger than CMYK.
  4. Myth #4: A profile is for calibration
  5. Myth #5: 5000K on a monitor is the same as 5000K in a light booth.
  6. Myth #6: You need to be a color scientist to use color management
  7. Myth #7: Setup Photoshop with your monitor profile as the working space.
  8. Myth #8: Use perceptual intent for all Photographic-style images
  9. Myth #9: The Saturation rendering intent sucks.
  10. Myth #10: Profile Rot or "A good profile gone bad"
  11. Myth #11: Printing a profiling target is a good way to evaluate a profile.
  12. Myth #12: CMYKLcLm printers are 6 color.
  13. Myth #13: Look at a print closely to see the color better.
  14. Myth #14: CRT Brightness & Contrast knobs control Brightness and Contrast.
  15. Myth #15: LCD brightness IS brightness which means it's not the same as a CRT.
  16. Myth #16: Two 5000K bulbs will match.
  17. Myth #17: D50 bulbs are available.
  18. Myth #18: The "Preserve Color Numbers" checkbox in Photoshop's proof setup doesn't matter much.
  19. Myth #19: You need a RIP for your printer if you want to proof.
  20. Myth #20: Adobe Gamma is pretty close to what you can get from an instrument calibration.
  21. Myth #21: There are perceptual rendering intents available when converting from scanner/camera->workspace or workspace->workspace.
  22. Myth #22: The a, b axis of Lab are red/green and blue/yellow.
  23. Myth #23: Photoshop's color setting dialog lets you edit an ICC CMYK profile.
  24. Myth #24: Working space selection in Photoshop affects profile building.
  25. Myth #25: Device link profiles are limited, hard-coded versions of normal ICC transforms and are therefore redundant, inflexible and are to be avoided.
  26. Myth #26: Graphing profiles to see their gamut gives pretty much the same results in the different tools that are available.
  27. Myth #27: Why would anyone ever want to choose a working space that is larger than you can print?
  28. Myth #28: The PowerBook G4 displays 16.7 million colors (or any display, for that matter).
  29. Myth #29: The more patches on the printer target, the better the resulting profile.
  30. Myth #30: If your RIP doesn't allow total ink limiting, just limit each channel.
  31. Myth #31: When setting up a RIP for proofing, you should match density and dot gain of the inkjet to the press.
  32. Myth #32: Relative Colorimetric intent means no color shift.
  33. Myth #33: The new SWOP guide (version 10) contains an effective summary of color management.
  34. G7 Myths: G7 Myths.
  35. Myth #35: Wide gamut monitors are the best! Everybody should have one.
  36. Myth #36: A wide gamut monitor will show me all the colors my printer can print.
  37. Myth #37: Lab is perceptually uniform
  38. Myth #38: Delta E 2000 is not a good equation to choose; I've heard that xxx is better.
  39. Myth #39: Curve3 will make my printer print GRACoL.
