Convertidor CMYK a RGB

CMYK-to-RGB conversion is the transformation of subtractive color data used in Color Printing into the additive RGB colors required for screen display.

The Subtractive to Additive Bridge

• CMYK (0-100%): A subtractive model where colors are created by absorbing light via ink (Cyan, Magenta, Yellow, and "Key" Black).
• RGB (0-255): An additive model where colors are created by projecting light (Red, Green, Blue).

Conversion Methodology

The transformation relies on the relationship between light absorption and reflection:

1. Normalize: CMYK percentages are converted to a scale of $[0, 1]$.
2. Apply Key Channel: Red, Green, and Blue values are calculated as:
   • $R = 255 \times (1-C) \times (1-K)$
   • $G = 255 \times (1-M) \times (1-K)$
   • $B = 255 \times (1-Y) \times (1-K)$
3. Integer Mapping: Results are rounded to the nearest integer in the $[0, 255]$ range.
