Dark blue in print

It converts to cmyk cleanly and holds its character from screen to paper. The cmyk build is 84, 78, 0, 40.

The same color needs a different cmyk build depending on the paper. Here is #18229a on both.

Coated stockgloss or silk, C

84 78 0 40

Ink sits on the surface, so colors stay bright and close to screen.

Uncoated stocknatural or matte, U

81 76 4 46

The stock absorbs ink and gains dot, so it needs a heavier build and reads a touch softer.

This color is saturated enough to sit near the edge of cmyk gamut, so expect a small drop in punch on paper and proof it before a long run.

How we calculate these values

Every value on this page for #18229a is computed, not guessed. We convert from sRGB to each space with the standard formulas, so the codes match what design tools show. The coated and uncoated cmyk builds differ because uncoated stock absorbs more ink and gains dot, so the same color needs a heavier, slightly duller build on press. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
