Vehicle graphics must be produced with cast vinyl that is then laminated with cast vinyl. There are vinyls that work well with pigment ink, such as your 9880, but even if laminated, the edge of the graphic will wick water and mold will grow rather quickly between the laminate and the surface of the vinyl. Unfortunately, this work should be done on a solvent or eco-solvent printer such as the Epson GS6000 or the new Epson SureColor S30.
Perforated vinyl is also usually printed with solvent printers and laminated with an optically clear laminate. If the graphic is not laminated, dirt will build up in the holes obstructing vision. Once the dirt gets in the holes it is very difficult to clean out. In addition, when it rains, vision will also be greatly reduced. It is also important to use the correct perforated hole size (50/50 vinyl to hole size) so the car will pass a light transmission test. Many law enforcement units have a light transmission tester that is also used to see if window tinting is too dark to comply with local laws. You may be able to find perforated vinyl that will print on your Epson, but be certain to laminate with an optically clear laminate that has a clear film release liner rather than a paper liner. Only a clear film liner will result in optically clear adhesive when it is applied to the perforated vinyl. Using a laminate with a paper liner will result in 'orange peel' adhesive that will not allow the driver to see out the back window due to the distorted adhesive that never smooths out after application.
I hope this makes sense. If you need additional information, send me an email or PM me through this forum.
