Proof Line Silk GS works with Dye and Pigmented ink sets. This unique coating and high-quality base provides a very smooth surface and greater color gamut than even many photo based papers. The Generation 2 type coatings were specifically designed with the onset of faster printheads running a more viscous ink. The results are immediate color stability and reduced ink usage. Silk GS is a great choice for anyone who needs to meet ISO, SWOP or GRACoL standards with their proofing system.
