发明名称 Method and system for improving the quality of two-sided watermarked printed documents
摘要 Methods and systems for improving the quality of two-sided watermarked printed documents through watermark alignment. An exemplary method comprises the steps of printing a watermark on the front of a sheet to create a first impression and printing the watermark on the back of the sheet to create a second impression, wherein the watermark is printed so that the first and second impressions are substantially aligned when viewed from either side of the sheet. An exemplary system may operate between a client node on which watermark selections are made by a user and a printing node on which watermark selections are applied to provide watermark alignment.
