Dark slate blue in print

The same color needs a different cmyk build depending on the paper. Here is #0c3aa3 on both.

Coated stockgloss or silk, C

93 64 0 36

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

Uncoated stocknatural or matte, U

90 63 4 42

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

The figures for #0c3aa3 come from standard color math, shown so you can check them. Rgb, hsl, hsv, lab and xyz are derived through the usual sRGB conversion formulas. 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 figure is the nearest match in our reference set by perceptual distance and it is an approximation, not an exact spot color.
