Blue in print

It is saturated enough that the cmyk build can shift slightly from screen to press, so proof it. The cmyk build is 89, 80, 0, 7.

The same color needs a different cmyk build depending on the paper. Here is #1b30ee on both.

Coated stockgloss or silk, C

89 80 0 7

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

Uncoated stocknatural or matte, U

86 78 4 13

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 #1b30ee is computed, not guessed. The rgb, hsl, hsv, cie-lab and xyz values follow the standard conversions from the sRGB color space. Two cmyk builds are shown because coated and uncoated papers behave differently, uncoated soaks up ink and needs more of it to hit the same target. The Pantone value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
