摘要： 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.
摘要翻译：计算机化系统模拟墨水吸收到一张纸上。扫描最靠近打印表面的部分，并将“纸张强度值”分配给形成在扫描图像上的每个像素。预先形成的印刷图像被放置在片材表面的扫描图像上，使得扫描图像中的每个像素具有打印图案中的相应像素。从打印强度值中减去纸张强度值以获得最终强度值，其提供如果将其应用于纸张的该像素区域时油墨将如何出现的指示。
