Abstract: Variable data printing workflows are enhanced for use with content that includes 2D code patterns, such as digital watermark data. One arrangement includes applying a filter to a content stream within a PDF document to extract both first variable pattern data for a first watermark pattern and second variable pattern data for a second watermark pattern. A first composite watermark pattern is then defined based on the extracted first variable watermark pattern data in conjunction with static watermark pattern data, and a second composite watermark pattern is defined based on the extracted second variable watermark pattern data in conjunction with the static watermark pattern data. A variety of other features and arrangements are also detailed.

Abstract: Advanced signal processing technology including signal encoding and digital watermarking. Disclosure includes monitoring spectral differences within control strip area to determine signal robustness of encoded signals printed outside of control strip area. Other combinations and technology provided too.
