Full-colour graphics for the rear window of a van, SUV, bus or pickup cap — the panel that turns dead glass into the most-read advertising space you own, because it sits at eye level of the driver stopped behind you.

This product prints on 70/30 perforated one-way vision film: a vinyl sheet that is 70% material and 30% open holes. From outside it reads as a solid printed graphic. From inside the vehicle you look straight through it. That is what makes it legal and practical on a window you still need to see out of — a solid vinyl decal would black the glass out completely. A promotional-grade perforated film is also offered where the graphic only has to last a season.

Be clear about the trade-off before you order. Rearward visibility through perforated film is noticeably reduced at night and in heavy rain, and the film cannot be fitted to a window swept by a rear wiper — the blade tears the perforation apart. It also should not go over defroster-heated glass edges where the adhesive can be lifted by heat cycling.

You receive the printed film cut to the dimensions you supply, ready to squeegee onto clean, dry glass. An optically clear laminate is strongly recommended on any vehicle that is washed or driven in winter: unlaminated perforation traps road grime in the holes and goes grey. Note that laminating a perforated film slightly reduces see-through, which is the price of it staying clean. Contour cut is available where the glass is a shaped or wrapped rear window rather than a rectangle.

Measure the visible glass, not the frame, and supply artwork at full size in vector or high-resolution raster. Keep the design bold — the 30% hole pattern eats fine detail, so thin type, hairlines and small logos will not survive the perforation. Solid shapes and large lettering are what this material does well.
