Claim One:
1. A method of determining a characteristic of an image forming apparatus, the method comprising: receiving halftone data defining a plurality of dot locations of a plurality of dots to be printed on a print medium; calculating distances between the plurality of dot locations in the received halftone data; determining a size of each simulated dot in a simulated reference image based on the calculated distances between the plurality of dot locations in the received halftone data, wherein determining the size of the plurality of simulated dots includes growing a size of the plurality of simulated dots based on the distances between the received plurality of dot locations, and wherein a Full Width at Half Maximum (FWHM) is utilized in determining the size of the plurality of simulated dots; forming the simulated reference image of the halftone data by transferring a plurality of simulated dots having the size determined based on the distances between the received plurality of dot locations onto the received plurality of dot locations in the halftone data; printing, using a print head of the image forming apparatus, the halftone data on the print medium to form a printed image having a plurality of printed dots; and determining a characteristic of the image forming apparatus by comparing the plurality of printed dots and the plurality of simulated dots in the simulated reference image, wherein growing the size of the plurality of simulated dots improves accuracy of the comparison.
