The white paper advises on opactiy, feathering, blending modes and other aspects of transparency


The Ghent Workgroup has published a new white paper intended to help designers better understand native transparency and the use of best practices to avoid common print problems associated with transparency in PDF for print production.

Written by Jason Lisi, associate professor at Ryerson’s School of Graphic Communications Management in Toronto, Canada, the freely downloadable document explains both the benefits and challenges of working with transparency in PDF files.
GWG chairman David Zwang explained, ‘We invited Jason to write this white paper to simply explain the solutions available for some of the more common issues printers and designers are dealing with on a daily basis. Understanding the benefits of using native PDF transparency in print production design, especially when PDF/X 4 files are processed, can help to avoid issues on press.’

The white paper is available from the GWG website at
