UltraPro SemiGloss Duo 255

Whether called Satin, Luster, Pearl, or Silk, these names almost always refer to an E-Surface finish. Just look to the nearest photo lab print and you will most likely see this pebbled finish. The DEPTH of this surface varies from paper to paper. The more shallow the depth the less you will notice the surface on a printed image.

Photo Grade products are designed to look and feel like modern photo lab paper. Most photo grade media are resin coated, which means they have a paper core covered by a thin layer of polyethelene (plastic) . Plastic gives the paper its photo feel, stability (flatness), water resistance, handling resistance, and excellent feed consistency.

Prints on photo grade media are stable over long periods. With pigment inks in a protected environment, you can see up to 80 years on-display life. All RC papers are Photo Grade for two reasons. Plastic content is not technically archival by museum standards. Also, the inkjet coating of all RC papers is slightly acidic. It facilitates instant drying and does not actually change the stability of your inks over time. Virtually all RC papers have optical brightening agents (OBAs).

Photo Grade Summary

• RC papers
• Plastic coated acid and lignin-free paper core
• Inkjet coating layer will have slight acidity
• Contain OBAs

Photobase resin coated (RC) inkjet papers always have a slightly acidic coating. The acid content (pH 6.8) makes instant ink drying possible. The level of acid content is not high enough to affect print stability over time.

The base stock of all Red River inkjet papers are acid free.
