METHOD AND SYSTEM FOR APPLYING A CONTENT-VARIABLE WATERMARK TO A DOCUMENT |
摘要 |
A system creates a copy of a document by: receiving an electronic representation a document to be copied onto a substrate; identifying a non-invasive watermark to be printed on the substrate; analyzing the document and the non-invasive watermark to determine whether a threshold amount of the non-invasive watermark can be printed in a white space of the document; and creating a secure copy of the document with the watermark. If the threshold amount of the non-invasive watermark can be printed in the white space, the system will print at least a portion the non-invasive watermark in the white space. Otherwise, the system will modify at least a portion of the non-invasive watermark to comprise an invasive watermark portion, and it will print the invasive watermark portion over a portion of the document's content. |

1. A method of creating a copy of a document, comprising:
receiving an electronic representation of a document to be printed onto a substrate; identifying a non-invasive watermark to be printed on the substrate; analyzing the document and the non-invasive watermark to determine whether a first threshold amount of the non-invasive watermark can be printed in a white space of the document; determining that the amount of the non-invasive watermark that can be printed in the white space is less than the first threshold; modifying at least a portion of the non-invasive watermark to comprise an invasive watermark portion; and creating a secure copy of the document by:
printing document content for the document on the substrate, andprinting the invasive watermark portion so that the invasive watermark portion covers a portion of the document content that is outside of the white space of the document. |
