The cover of a binder or album is provided with a coating which is receptive to inks which are water based, solvent based or gel based, and which is substantially water-fast after the ink has dried. A coated transparent or translucent sheet may be provided on the front cover of the binder to form a pocket so that visual material inserted in the pocket may be traced, and so that the cover may be personalized. The coating may include finely divided porous particulates and a binder which includes as a component a water soluble polymer. The coating may be applied to backpacks, zippered binders, and pencil pouches, and to the transparent sheet material overlying photographs mounted in a photo album. Personalized writing or designs may be written or drawn onto the coated products using ink pens of virtually any type.

A vacuum flow restricting print media transport apparatus comprising: a perforated belt and ported platen combination having an effective belt total porosity less than platen porosity and having a sliding contact relation, at least seventy-five percent (75%) of a pressure drop in the apparatus occurring through the perforated belt by way of said effective belt total porosity being less than said platen porosity. 11. An ink-jet hard copy apparatus print media transport belt for use with a vacuum platen having a plurality of vacuum ports, each port having a port cross-sectional area, the apparatus comprising: an endless loop metal belt, and an array of perforations through the metal belt, each of which is configured to have a perforation cross-sectional area less than said port cross-sectional area, providing a predetermined net porosity of said platen and said perforated belt in combination such that a substantially uniform airflow is established for holdin
