Claim Text:
1. A method comprising: printing test patterns in different test pattern areas on print media using a printer to produce a printed item, said printer having a printing width, each of said test pattern areas being in a different location of said printing width, and each of said test pattern areas partially overlapping another of said test pattern areas; individually scanning said test pattern areas of said printed item using a scanner having a scanning width that is less than said printing width to produce individual scans of said test pattern areas, widths of said test pattern areas being equal to or less than said scanning width; calculating individual response curves for said individual scans using a processor operatively connected to said printer; adjusting said individual response curves based on differences between overlapping portions of said individual response curves, using said processor, to produce an adjusted combined response curve; and calibrating cross-process characteristics of said printer based on said adjusted combined response curve, using said processor.
