Printing Files Enhanced with Digimarc

15 May 2023

A brief overview on what to expect when proofing, plating, and printing

Digimarc Barcode, also known as DWCode, is a printed code applied through subtle adjustments to dots within an image or design element. The pixelated appearance allows detection by enabled devices, such as phones, computers, barcode scanners and machine-vision equipment. The code carries the same information as the 1D barcode (UPC / EAN) placed on the package.

Considerations

• Do not perform any color correction or image scaling, and do not re-use any raster elements or plates - all can lead to data integrity issues and require reprinting.
• When viewing separations at magnification, pixel modulation is evident. This may appear as ‘mottled’ or ‘ink dot scum,’ but the appearance is expected and should not be altered. When viewed as a composite, the code is generally imperceptible.
• When the code has been applied to a (previously) solid spot color, the spot color separation will be screened and requires addressing screen angle.
• The enhancement provider must know before providing the enhanced file if a cut back, transfer, or push curve will be applied at Raster Image Processor (RIP).
• Predicted Tone Value Increase (TVI) is accounted for with enhanced press-ready file(s) and must be stable and maintained throughout the press run. An increase in TVI within the 3/4 tones may cause a decrease in code performance.
• The provided minimum dot (min dot) on press is present and should be held throughout the press run. The code’s performance will be reduced or lost if minimum dot is not maintained.
