Steel 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 100, 33, 0, 40.

The same color needs a different cmyk build depending on the paper. Here is #006699 on both.

Coated stockgloss or silk, C

100 33 0 40

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

Uncoated stocknatural or matte, U

96 34 4 46

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 #006699 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. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
