Chicago, IL – GPA announces the rollout of their newly enhanced and expanded Ultra Digital swatchbook, which contains an impressive selection of over 100 printed samples of their most popular substrates for HP Indigo digital presses. Its nine sections cover everything an Indigo press owner needs to find the right substrate for virtually any application.

This new swatchbook is double the size of the previous version, and its seven product sections include:

- Coated Papers
- Uncoated Papers
- Specialty Fine Papers
- Coated C1S & C2S Board Papers
- Specialty Application Substrates
- Pressure Sensitive Papers
- Synthetic Film Substrates

The new Ultra Digital swatchbook features some of the latest and most innovative substrates on the market today. Each sample lists the sheet sizes available, brightness, whether it's treated or untreated, GSM, caliper, and sheets per carton/package.

Each product section includes application suggestions and color photos of actual printed samples. Also new is a special section highlighting GPA's Print Trial Process (PTP), a tool designed to help digital printers evaluate and determine the optimum performance of any given substrate. The last section details GPA's nationwide distribution network and information on order placement.

The swatchbook was printed 4-color on an HP Indigo 3050. Ultra Digital 100# White Matte Cover was used on the front and back covers, and the tabs were printed on Ultra Digital 80# White Matte Cover.
