Using Waterproof films dramatically improves the quality of your films for all inkjet printers.
Waterproof films have a different coating on them that retains the ink and encapsulates it once printed on the film. A standard inkjet film just has an inkjet receptive coating sprayed on it.
When printing on a standard inkjet film the ink is not encapsulated into the coating of the film, and just sits on top of it. When sitting on top of the film it take a long time to dry, sometimes it runs, sometimes it cracks after it dries, and sometimes the ink rollers pass through the ink leaving streaks in the film.
Waterproof Clear Films are manufactured of a very unique fast drying formulation that works with both Pigment and Dye based inks used in most inkjet printers. This formulation allows for minimal dot gain, dry on contact, and max density technology.
The emulsion layer on the film certainly helps speed the drying process and edge quality greatly reducing dot gain as well. Avoid using a films with a thin, almost "clear" appearance and never use a "non water proof" film. Your dye ink is water based so use a proper film. The name alone "non waterproof" should tip you off that its not the best product for your needs. The slightly cloudy emulsion of the film does not effect the exposure process.
