DYE inks bleed like crazy with you get any water on them! Nano porous coatings on pigment inkjet films don't let the ink bleed. Water proof film can't actually be waterproof, or water based ink would be repelled! It should be called bleed resistant film, but it got named before pigment inks were mainstream. Pigment inks must use nano porous coatings because the particles in the ink needs to be able to go into the coating. Inkjet Film for Screen Making Positives I posted this thread: "waterproof" films and pigment based ink? FastINK is DYE ink sold by usscreen.com and they recommend their 'waterproof' film, rather than film with a swellable coating used for DYE ink that is half the price of nano porous film. Nano porous coating can absorb DYE or Pigment ink, much like a gravel driveway will absorb anything you pour on it. The reason the EPSON 3000 was such a hit was because it used DYE ink and had a media setting for Back Light Film. Alas, that is not the case anymore, because all the modern EPSON printers use Pigment Ink. EPSON Printers for making Screen Printing Positives

Thank you this helped a lot.
