Offset printing

DELROTI prints offset in format sheets of 35 x 50 cm and 50 x 70 cm or in any other format, by request, using printing machines in two and four groups of color.

Offset printing uses the CMYK system, and treatment of the four basic colors necessary for image processing in printing is made by using the raster technique. Paper surface is partially covered by circles in the four colors (cyan, magenta, yellow, black), which are small and dense enough for the eye to mediate the effects of the surface covered by white circles, and create a uniform image .

Offset printing is the printing procedure by which the image on the printing matrix is transferred on to paper through a special rubber cylinder. During this operation performed on special machines, the printing matrix does not come in direct contact with the printing support (offset).
