Multiple printing method for transparent material has over-printing of similar ink colors used for providing high color intensity image

摘要

Printing method has a number of printing inks of the same or a similar color printed one on top of the other for providing a printed image of increased color intensity. The red-green-blue color information or the cyan-magenta-yellow-black color information required for printing a color image is transferred to a film or a printing medium using an amplitude modulated raster and then using a frequency modulated raster for preventing Moire patterns.
