There is no particular order to the questions as they are all interrelated and often overlap. One consideration is how long the win- dow graphics need to last. If we're doing a vehicle wrap that extends across the win- dows, then we choose a cast perforated film like 3M 8170-P50 so we get more durabil- ity to correspond with the life of the wrap. If it's a storefront window advertising a holiday special, which means it doesn't need to last more than a few months, we might consider a film like Avery Dennison MPI2077, a short-term, intermediate film with ultra-removable adhesive for ease of removal. SOLID VERSUS SPOT GRAPHICS In this case, we're determining the coverage the customer wants. Are we covering an entire car window to extend a wrap or an entire storefront window to block visibility? Solid coverage is often a great option for windows to provide maximum adver- tising while still offering options for visibility and light blocking. Stripes across multiple windows or banners of graphics on a window are a great option for storefront windows too. It provides large chunks of adver- tising and storefront branding by ty- ing together multiple windows while keeping total square footage down compared to complete coverage. Often spot graphics can make a large statement on a storefront win- dow while still allowing excellent vis- ibility out from the inside. This might be large contour cut lettering or a logo that covers multiple large windows. These kinds of decorative approaches offer a unique look. If the customer is on a budget, spot graphics might be the best choice to keep costs down. Front glass lettering, a logo, or a bullet list of information often work best as spot graphics and provide information in an effective manner. VISIBILITY VERSUS LIGHT BLOCKING I mentioned this as part of the previous consideration and it's one of those areas where the questions we ask often overlap in how we choose a film. Oftentimes a cus- tomer wants to achieve maximum cover- age on their windows for advertising, but also still wants to allow their customers or employees to see out from the inside. In this case, a perforated film is a great option. If the advertising is on a store- front, a 65/35 perforation pattern is a good choice. Avery Dennison MPI 2728 is a calendered film that provides one-way visibility on stationary windows. ClearFocus 50/50 ClassicVue perforated window film is another great choice for ve- hicles. The hole pattern provides advertis- ing coverage from the outside and visibility out the windows from the inside. Perforat- ed films also reduce heat and provide light transmission. Perhaps the customer doesn't want any visibility through the window; rather, they want to block visibility into a vehicle, for example. We often get this with commer- cial vans that have rear windows. A solid film allows the customer to continue their wrap across the windows while also block- ing visibility into the van. Storefronts with windows looking into a storage space might also want total coverage with no vis- ibility in from the outside. Full coverage to block visibility then leads to the question of how much light the customer wants to allow through. 3M Controltac print film 40C offers a gray adhesive option with an opaque opac- ity while 3M Envision Translucent Film IJ3730-50 uses the interior lighting to help pop the color in the printed image, while still allowing light to come through the image. PRINTED VERSUS DECORATIVE This consideration isn't to imply that a printed film can't also be decorative; rather, it's to consider the look a customer is going for. Are they looking for a window film op- tion that is printed, typically for advertising purposes, or one that is decorative? Etched-look vinyl and other specialty films can create privacy while also enhancing the aes- thetics of a space.
