Abstract (en)

[origin: EP1568490A1] The method involves direct engraving of cells (10) for the admission of printing ink in the surface of pneumatic cylinders under low pressure. The cells are formed from a pre-determined number of engraved pixels (11). The engraving depth of the pixels can be modified during the expansion (14) of the two dimensional element (15) of the pixel (13). The engraving depth can be specified in gradated depth steps in a design from 1 to 8 bits.
