Why does a metal border requires an additional frame when offset printing?
2002-10-08
The CMYK printing is based on 4 colors of reference: Cyan, Magenta, Yellow, and Black. But the high definition of this process relies on the fact that these 4 colors are printed on a “white” background. In the case where the printing fits exactly to the outside cutting, the white colour covers the whole surface. But if a metal boarder must appear, we will need an additional frame to define the surface to print in white, which will be smaller than the outside cutting.
