Abstract:
The present application provides a screen method for intaglio printing, comprising: dividing multiple classes of regions according to a brightness range; and generating screen dots with various screen patterns for the grouped classes of regions. The present application also provides a screen device for intaglio printing, comprising: a dividing module configured to group multiple classes of regions according to the brightness range; and a generating module configured to generate screen dots with various screen patterns for the grouped classes of regions. Since multiple kinds of screen patterns are applied in the technical solutions in present application, the problem, i.e., water ripple will occur in the prior art, may be addressed, so as to improve the quality of printing.
