Print, assemble and go! The most practical way to bind work into a screwpost portfolio book is to use our Pre-Punched Inkjet Paper. Made of double-sided, smooth, bright white, heavy-weight (235 gsm) matte paper, the sheets are pre-punched and scored so they can be printed then bound directly into a screwpost 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. Printer profiles for these sheets can be downloaded at: www.moabpaper.com/icc-profiles-downloads. Select your printer brand, then printer model and then download the profile listed for "Pina Zangaro Matte" at the bottom of the list.
