What is a color seam?
Thicker substrates can be created by mounting 2, 3 or more sheets together. In such an application with 3 sheets, a color seam is a center layer of paper or a layer that's wedged between two sheets that appears as a middle "seam" on the final product. They can appear in a variety of colors. Color seams are used in both our Prestige line of products and our Layer Cake products.
