50lb. Premium Matte Double-sided Post Cards

Papers with the Archival designtation can take many forms. They can be glossy, matte, canvas, or an artistic product. These papers are acid free, lignin free and can be made of virgin tree fiber (alpha cellulose) or 25-100% cotton rag. They are likely to have optical or fluorescent brightening agents (OBAs) - chemicals that make the paper appear brighter white. Presence of OBAs does not indicate your image will fade faster. It does predict a slow change in the white point of your paper, especially if it is displayed without UV filter glass or acrylic.

Archival Grade Summary

• Numerous papers - made from tree or cotton content
• Acid and lignin free base stock
• Inkjet coating layer acid free
• Can have OBAs in the base or the coating

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.
