ABSTRACT:
A computerized system simulates the absorption of ink into a sheet of paper. A portion closest to the print surface is scanned and a "sheet intensity value" is assigned to each pixel formed on the scanned image. A pre-formed printed screen image is laid over the scanned image of the sheet surface so that each pixel in the scanned image has a corresponding pixel in the print pattern. The sheet intensity value is subtracted from the print intensity value to obtain a final intensity value, which provides an indication of how ink will appear if it is applied to that pixel area of the sheet.
