Formula breakdown

Formula

piecewise blackbody Kelvin → RGB regression fit (Tanner Helland approximation)

= 255

Note

Simplified model: these are standard prepress and typographic relationships computed on nominal values. Real press bulk, paper caliper and shrinkage, ink limits for a given profile, font metrics and binding allowances vary by supplier and by job, so confirm with your printer and a proof before going to press.
