Print assemble and go! The most practical way to bind work into a portfolio book is to use our Scored Inkjet Paper. Made of double-sided, smooth, bright white, heavy-weight (235 gsm) matte paper, the sheets are prepunched and scored so they can be printed then bound directly into a portfolio book. The paper is water resistant and archival and is available in five sizes with standard hole configurations. Sold in packs of 25 in an archival tuck flap envelope. Not compatible with 3-Ring Binders or Multi-Ring Portfolios.
