Abstract: 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

Abstract: An apparatus capable of dividing an m-value image into a plurality of divided images and performing quantization into an n-value image (2?n<m) for each divided image includes a first quantization unit for quantizing a first region in the divided image similarly to a region to be joined, and a second quantization unit for sequentially quantizing a second region in the divided image including the first region. If the second quantization unit quantizes the first region, parameters for the quantization processing is corrected using a quantization result in the first quantization unit such that the quantization result approaches the quantization result in the first quantization unit.
