Methods and systems herein provide for reducing artifacts during printing. One printing system is operable to prepare a continuous tone image (CTI) for printing onto a print medium by generating an initial half tone image (HTI) based on the CTI. The printing system includes a printer and a print controller. The print controller filters the initial HTI and the CTI with a perceptual filter and determines an error between the filtered CTI and the filtered HTI. The print controller prints the HTI via the printer to determine printer artifacts and processes a scanned version of the printed HTI to determine an error between the filtered CTI and the scanned and filtered HTI. This processing updates the initial HTI and reduces the error between the filtered CTI and the filtered HTI.
A printing system that compensates print engine artifacts, the printing system comprising:
The printing system of method 8, wherein identifying the plurality of combined errors comprises applying a human visual system (HVS) to each combination of the respective one of the plurality of intermediate errors and the second error.
A computer readable medium tangibly embodying programmed instructions which, when executed by a computer system, are operable to execute a method of compensating print engine artifacts, the method comprising:
The printing system of method 16, wherein identifying the plurality of combined errors comprises applying a human visual system (HVS) to each combination of the respective intermediate errors and the second error.
A method that compensates print engine artifacts, the method comprising:
