US Patent 7913160 Document versioning based on layer content

A document can contain multiple print layers. Different layers can be combined to produce different document versions. In this manner, a document can have an English version and a Spanish version that share graphics layers but have different text layers. A document's different layers can be difficult to track and the difficulty can lead to errors in document proofing and production. A discrimination module can automatically classify layers as common, graphics, and text containing. The text containing layers can be further grouped by native language. The layer groups can then be automatically combined to produce the desired document version specifications that can be rendered as document versions.
