paper types

When creating my book I have 3 options of paper 1) standard 2) premium 3) proline. I have looked into the paper types so I know when choosing my paper what I will be getting,  I should choose my paper type based on the finish that I want to have within my book.
Premium paper
Premium Paper is the crème-de-la-crème of our paper offerings. This 100-pound text silk-finish paper is 35% heavier than our standard paper, featuring improved opacity and stellar image quality to make your best work shine.
For our pro users, Premium Paper is another way to present your best work to your clients on 100-pound paper. If you’re already using the B3 Custom Workflow process, adding Premium Paper to the mix will simply blow you – and your clients – away.

proline
The first two ProLine papers (Pearl Photo and Uncoated) are produced by Mohawk Fine Papers, Inc.
Blurb’s Pearl Photo paper is a rebranded version of Mohawk proPhoto paper. The 140 lb (190 gsm) semigloss paper is slightly heavier and glossier than the Premium Lustre paper used in other Blurb photo books. The Pearl Photo paper emulates the traditional photographic papers, enabling your books to resemble collections of custom photographic prints.
Blurb’s Uncoated paper is the popular Mohawk Superfine Ultrawhite in Eggshell finish. Blurb CEO Eileen Gittins noted that “Mohawk’s rich, heavy uncoated paper with its organic texture is hot in the design community right now.”
