Yes, you can select different paper types for the inside and outside of your book project. By default, our online pricing calculator already offers cover stock for the outside cover if needed (ie: 14pt uncoated cover for the cover and 70# uncoated text for inside pages). If you need a custom paper type (thicker cover stock, laminated cover, foil stamping on the cover, etc) we can do that as well. It will be considered a custom quote and you will need to contact our Support Team to get pricing on your custom project.
