Slate 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 77, 69, 0, 6.

The same color needs a different cmyk build depending on the paper. Here is #374bef on both.

Coated stockgloss or silk, C
77 69 0 6
Ink sits on the surface, so colors stay bright and close to screen.
Uncoated stocknatural or matte, U
75 67 4 12
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 #374bef are worked out. Rgb, hsl, hsv, lab and xyz are derived through the usual sRGB conversion formulas. 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 figure is the nearest match in our reference set by perceptual distance and it is an approximation, not an exact spot color.
