S I G N & D I G I T A L G R A P H I C S • December 2019 • 53 ferent substrates require different adhesive chemistries to provide the best result, particularly if you want to increase the chance for clean removal at the end of the graphic's life. "One of the biggest mistakes to avoid is using a product with an inadequate adhesive that peels away from the substrate, lead- ing to a call-back and rework that could eliminate the profit margin for the job. 3 M has developed an Adhesion Test Kit that drastically improves the success rate by identifying the right product for the substrate. The test kit is most commonly used on walls where there are challenges with different types of paints and coatings, but it can be used on any surface." He adds that another consideration is durability. "What is the expected life of the graphic? Does the customer want a warranted solution? 3 M makes this part easy with published warranties for its products under the 3M MCS Warranty on www.3M.com/graphicswarranties. To assist shops in selecting the right product for the application, 3M has an online prod- uct selector at graphicsselector.3M.com. You simply select the application and one or two additional project details, and it returns the recommended product instantly." Cook notes that in most cases, 3M's digitally printable products are compatible with all major printing platforms including latex, solvent, eco-solvent, and UV. He adds that sometimes customers find that a certain product provides better image quality on their printer, although oftentimes print quality issues can be resolved through printer settings and profiles. Cook says that 3M Controltac Print Film 40C media was on full display in the Baltimore Library Project and that it transformed inner city school libraries in Baltimore to improve the academic achievement and lives of its students. Graphics and artwork were an integral part of the transforma- tion process, but come with challenges including walls with bookcases, vaulted ceilings and more. Dave Gimbel and his team at Signs by Tomorrow from Alexandria, Virginia, worked with the design team to conceive and install unique artwork for each library. Turner Signs utilized Drytac Polar Grip for the Hall Cross Academy project. Images courtesy of Turner Signs, Drytac. ReTac adhesive technology, unlike standard removable adhesive, never turns permanent, so it can be installed and removed indoors without damaging the surface it is adhered to.
