Abstract
A method for determining printing ink usage efficiency (weight of ink required to print a given area) in a printing process is disclosed where the method is based on the analysis of pigment in the printed ink.
Claims20
A method for determining printing ink usage efficiency in a printing process based on an analysis of a pigment in a printed ink, said method comprising:
- (a) extracting said printed ink containing said pigment from a printed surface area into a liquid solution;
- (b) measuring amount of said pigment in the extracted ink;
- and
- (c) calculating said printing ink usage efficiency based on the analysis of and the amount of pigment in said area.
