The fine print
About Pantone, CMYK and conversion accuracy
Pantone is a library of pre-mixed spot inks — each colour is a specific physical ink formula. Pantone produces highly consistent colour across print runs and substrates because the printer is laying down the exact ink, not approximating it with process colours.
CMYK is the four-ink process used in most commercial printing — cyan, magenta, yellow and black laid down as percentages to approximate any colour. CMYK is cheaper per print job because the same four inks produce the full gamut, but the gamut itself is meaningfully smaller than Pantone's. Vivid greens, electric blues and saturated oranges often shift to duller approximations when converted from Pantone to CMYK.
The values shown in this tool are approximations. They reflect standard published process-equivalents and will reproduce close to the original but never identically. For colour-critical work, source values from a current Pantone Color Bridge guide, confirm with your printer's ICC profile, and soft-proof in your design software before signing off a press proof.
