Dark blue in print

A color this vivid sometimes sits just outside cmyk gamut, so expect a small dip in punch on paper. The cmyk build is 66, 100, 0, 37.

The same color needs a different cmyk build depending on the paper. Here is #3700a1 on both.

Coated stockgloss or silk, C

66 100 0 37

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

Uncoated stocknatural or matte, U

65 96 4 43

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

Here is how the numbers for #3700a1 are worked out. We convert from sRGB to each space with the standard formulas, so the codes match what design tools show. The uncoated cmyk build carries more ink than the coated one, which is what a printer would compensate for when the same color runs on a rougher stock. The Pantone value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
