Abstract:
1. A method for calibrating multiple printers in a networked environment, comprising: causing each of said printers to generate a printed target sheet comprising a plurality of colored patches; scanning said printed target sheets from each of said printers to obtain measured reflectance values of said colored patches; causing a computer processor to associate said measured reflectance values with a specific one of said multiple printers based upon data embedded in said color patches; creating separate calibration profiles for each printer using said data embedded in said color patches to determine a destination printer for each calibration profile: prior to causing each of said printers to generate a printed target sheet, causing said computer processor to generate calibration target sheet pattern files for each printer; wherein said calibration target sheet pattern files further comprising an embedded data portion associating said target sheet pattern file with a specific one of said printers; wherein said embedded data portion further comprising color patches whose measured reflectance values match reflectance values in a lookup table, said lookup table associating data values with said reflectance values; and wherein said data values are selected from the group consisting of: (i) the date on which the target sheet was generated, (ii) the number of the current target sheet, (iii) the total number of target sheets currently generated for said specific one of said printers, and (iv) an identification of said specific one of said printers.
