Available in either polyester or polypropylene, these plastic sleeves will hold and protect your print. Sheet protectors can be cleaned with isopropyl alcohol (rubbing alcohol) and a soft cloth. Rotating sheet protectors within your book will help to avoid concentrated wear. Sheet protectors are subject to "wear and tear" and should be replaced regularly to maintain the maximum level of presentability. The maximum recommended number of prints displayed per side is one.

DETERMINING THE PROPER GUTER WIDTH
Creating a gutter (the space between the printed area and binding) is the best means for achieving a portfolio with pages that lie flat. Consider the relationship between the gutter and the number of pages: if you add more pages, you will need a wider gutter, which will result in trimming your pages. Refer to the chart below as a guideline for your measurements when trimming your pages. Exact specifications may vary depending on your paper weight. It is recommended that you pretest to determine the dimensions most suitable for your portfolio.
