Technical Specification & Mathematical Principles

Conversion follows the unified pipeline: HEX → sRGB → Fractional Linear RGB → CMYK.

When K = 100% (pure black #000000), chromatic components are zeroed out: C = 0, M = 0, Y = 0 to conserve ink.

Frequently Asked Questions

The pipeline parses hexadecimal bytes into digital RGB channels, derives the key black pigment K = 1 - max(R', G', B'), and computes subtractive cyan, magenta, and yellow ink proportions.
