OFFSET PRINT | BLACK

For several reasons the black resulting from the combination of the three primary pigments aren’t pure and needs to add black ink into the system. Others reasons are:

Use 100% cyan; because magenta and yellow produce an ink layer that take much time to dry and can tear the sheet if is very thin.


Texts are printed generally in black having much detail which will be impossible to reproduce with the overprint of the three inks.

The black pigment is the more cheap.

The graphic Industry CMYK uses a mixture of inks on paper and the other CMYK used in the computer systems is only a variation of the RGB.

The spectrum of the colors CMYK (graphic) is much smaller that RGB. This means that not all colors see on the monitor can be printed.
