GPA has a new addition to its collection of Ultra Digital Synthetic Substrates: Double Opaque and Near Dead Opaque Styrene for HP Indigo presses. Styrene is a durable substrate that offers added stability and resilience over papers while serving as a less expensive alternative to other hardworking films. GPA offers Styrene in a 10 mil thickness with a matte/matte finish in 12 x 18 sheets. The opacity options are Double Opaque, which allows some show-through depending on the light source, and Near Dead Opaque, which is ideal for two-sided signage due to its high opacity. GPA continues to offer Ultra Film Styrene for offset presses in a variety of opacities and thickness ranging from 10-30 mil.
