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 85, 100, 0, 34.

The same color needs a different cmyk build depending on the paper. Here is #1a00a9 on both.

Coated stockgloss or silk, C

85 100 0 34

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

Uncoated stocknatural or matte, U

82 96 4 40

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 #1a00a9 are worked out. The rgb, hsl, hsv, cie-lab and xyz values follow the standard conversions from the sRGB color space. 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.
