We use one of two different types of paper for our prints: 60lb Polar Matte or 60lb River Linen. Both of these papers are acid-free, high-performance papers for bright colors and deep blacks. The print subject matter dictates which paper is used - art with more dark tones prints best on the 60lb Polar Matte. Art with brighter and lighter tones is best paired with the 60lb River Linen.
