Daniel Valade, product manager, Color Products and Cutters at Roland DGA, Irvine, California, says when select- ing the film to use for a specific job, be sure to evaluate the installation surface and take that into consideration before choosing the media.

Adhesives paired to these films also vary depending on your needs as permanent and removable." Walton says choosing the correct film depends on how long the customer wants the film to stay on. There are basically three types of films: changeable for short term (1-2 years); removable for long term (3-5 years) and permanent. Allen notes that depending on what the customer wants, your film choice will change. "If they want a textured film, such as Avery Dennison MPI 2600, or a matte or gloss film, you will need to make a proper film selection. Also, a textured (Image courtesy of Brand Ink)
