A wide variety of preprinted films is available, for example wood grain,
marble, fur, leather, camouflage and carbon fiber fabric patterns. The process
can be used for parts with a three-dimensional shape, with curved surfaces and
round corners, such as car interior parts, computer housings, telephones, etc.
Sharp corners must be avoided, as they tend to break the film. The parts are
provided with an all-over pattern and precise positioning of the pattern on
the part is not possible.
A colored primer is sometimes used. Products with a carbon design can for
example be primed black and parts with a wood grain design can be primed
brown. A protective transparent topcoat is normally applied for abrasion and
UV protection.
The compatibility of the coating with the part material should be checked and
prototype testing is recommended.
The parts must be clean in advance of the decoration process, free of oil,
grease and mold release, and must receive a
cleaning treatment if necessary.
