Method of halftone screen linearization via continuous gradient patches |
摘要 |
A method of calibrating an electrophotographic machine having an image bearing surface includes depositing a toner patch on the image-bearing surface. The toner patch has a nominal coverage that varies substantially continuously from end to end. Light is emitted onto a selected one of the areas of the toner patch. An amount of light that is reflected off of the selected one area of the toner patch is measured. The emitting and measuring steps are repeated for each of a plurality of different areas of the toner patch. At least one electrophotographic condition is adjusted. The adjusting is dependent upon the measuring steps.
