EFI Validation PS Publication Premium Proofing Media is a competitively priced, 100 gram proofing media for use with both pigmented and dye-based ink sets. This media uses an actual publication press stock with a high quality microporous inkjet coating. PS Publication thus offers the exact look and feel of an offset press stock while remaining compatible with all available aqueous ink sets and demonstrating sufficient gamut to accurately proof commercial, publication and packaging print. Being a true publication stock, PS Publications is an ideal replacement for more expensive direct-to-substrate proofing systems.
