Had a damaged 44" roll of Red River Etching 315. Their customer service is always good so I was able to get the roll replaced. However, she mentioned on the phone that red river doesn't make Etching 315, which is standard in the industry, nor do they apply any sort of inkjet coating. They simply get 44" rolls and either resell them or cut them down from these rolls. She wouldn't tell me who their supplier is. Stands to reason that it would cheaper to just buy the paper from their supplier rather than going through them. Does anyone know who supplies it?
