Mostly used for large format printing, plotting, and other specialized uses, mylar is translucent plastic sheeting that can be printed or drawn on. Used as an overlay, it can be drawn on and wiped clean multiple times to show revisions. Mylar prints can also be photographed. These are clear sheets of plastic used with overhead projectors for presentations. Not all printers can handle transparency paper.
Vellum is translucent paper that can be printed on most laser and inkjet printers.
Since it is clear, it can be used as an alternate to film for proofs, positives, and other kinds of drafts. Inc. All rights reserved.
