Dry Offset Printing

Guanyu plastic has facilities for offset printing, also referred to as offset lithography. In this process the ink is not directly pressed onto the paper, but is distributed from a metal plate to a rubber mat where it is then set onto the paper. The colours used in offset printing are usually Cyan, Magenta, Yellow and Black, represented with the letters CMYK. Different percentages of each of these four colours create virtually every colour used in offset printing. There are colour matching systems, such as the PANTONE® system, that allows print buyers to see the colour. The code for that colour can be entered into the offset printer’s computer and it will calculate the percentages of each colour to be used.
