Why do prints still show color differences even when using CMYK color mode？

Even if your design file is created in CMYK color mode, slight color variations between what you see on screen and the final print are normal.

This happens because digital displays (RGB) and printers (CMYK) use two completely different color systems:

• RGB (Red, Green, Blue) — used for screens. It combines light to produce bright and vivid colors. Color appearance may still vary between different screens due to variations in brightness, calibration, and display technology.
• CMYK (Cyan, Magenta, Yellow, Black) — used for printing. It mixes inks that reflect light, so printed colors appear softer and less luminous, often resulting in a slightly darker appearance compared to what you see on screen.
