CMYK to RGBA Conversion Guide

CMYK and RGBA are two different color models used for printing and digital display respectively. Important considerations when converting:

  • CMYK is a subtractive color model that creates colors by absorbing light, primarily used for printing
  • RGBA is an additive color model that creates colors by emitting light, used for digital displays with an alpha transparency channel
  • Due to gamut differences, some CMYK colors may not be precisely representable in RGBA
  • Converted RGBA colors may appear different on screen compared to their printed counterparts

Conversion Formula

CMYK to RGBA conversion uses the following mathematical formula:

R = 255 × (1 - C/100) × (1 - K/100)
G = 255 × (1 - M/100) × (1 - K/100)
B = 255 × (1 - Y/100) × (1 - K/100)
A = User-specified transparency value (0-1)

This converter uses the above formula to transform CMYK values into RGBA values, helping designers and print professionals bridge the gap between digital media and print media.
