Abstract

See full text

Disclosed is a method of determining characteristics of a printer, the method comprising the steps of receiving print data, defining dot locations to be printed on a print medium, determining from the dot locations a dot frequency measure reflecting the number of dots to be printed on at least a part of the print medium, forming a simulated reference image of the print data comprising simulated dots corresponding to the dot locations in the print data, determining a size of the simulated dots in the reference image, this size being inversely related to the dot frequency measure, printing the print data on the print medium using the image forming apparatus to form a printed image, and determining characteristics of the image forming apparatus by comparing the printed image and the simulated reference image.
