Screen Colour vs Printed Colour: RGB and CMYK Explained

Colours on a phone or monitor can differ from the print because screens display RGB light while printing uses CMYK ink or toner. Some shift is normal. You can make it more predictable, but not identical.

🎨 Why colour changes

  • RGB screens show bright colours CMYK cannot reproduce exactly.
  • Every screen has its own brightness and calibration.
  • Paper colour, texture and finish change how ink or toner looks.
  • Converting an RGB file to CMYK can shift saturated blues, greens, oranges and neon colours.

🛠️ How to prepare

  1. Work in CMYK where your software allows it.
  2. Use 300 DPI images at final size.
  3. Do not use a phone screenshot as a colour reference.
⚠️ Warning: CMYK preparation makes changes more predictable but does not guarantee an exact match to a screen. If colour is critical, order a physical sample or proof on the intended material and finish before a larger quantity. See ordering a sample first.
