QUESTIONS AND ANSWERS
1. What is Clear Focus One Way Vision film made of and how does it work?
Most Clear Focus One Way Vision films are made of polyvinyl chloride (PVC) with up to 50% of the film micro perforated to achieve the desired image resolution and one-way visibility. Some Clear Focus One Way Vision films are made of polyethylene terephthalate (PET), which is recyclable and contains no PVC. The black (non-imaged) side of the film through which people see maximizes its transparency. Lighting is the final ingredient: For optimum effect, lighting on the graphics side must be brighter than on the non-imaged adhesive side.
2. What are some of the benefits of using perforated One Way Vision vinyl films?
> New media space
Clear Focus One Way Vision film creates new, innovative media space without obstructing the view. It also creates new business and advertising opportunities that are not available with conventional opaque signage.
The film can be used on the windows of emergency, utility and delivery vehicles, banks and other financial institutions, airports – on virtually any glass door or window where visibility is important for safety and security.
> Heat and glare control
Perforated One Way Vision film reduces heat and glare from the sun, making it ideal for residential and commercial buildings, retail stores, museums and art galleries, show rooms etc.
3. What methods can be used to print the films?
Our risk-free exterior-mount film, SuperVue, is uncoated and accepts wide-format digital imaging solvent, latex and UV-curable inkjet, thermal transfer, electrostatic transfer and airbrushing.
Fast One Way is printable in solvent and UV ink wide format printers.
Interior-mount ClearVue Interior is designed primarily for UV print but it is solvent ink compatible as well.
JetVue is coated and is therefore only compatible with wide-format aqueous ink printers.
4. Are there any special considerations to keep in mind when printing One Way Vision films?
Yes, there are special considerations. They are listed in our General Instructions document.
Graphics printed on perforated window films tend to look less vibrant than those printed on solid vinyl because up to 50% of the window vinyl is missing due to the perforation process.
Given the wide array of inks, printers and other variables involved in printing, we strongly recommend performing a test prior to actual production. This applies to both printing graphics on our perforated window film products and applying an overlaminate to the printed graphics.
5. What’s the difference between exterior-mount film and interior-mount film?
Exterior-mount (also called “black/white”) film attaches to the outside of the glass. With exterior-mount film, the image is printed in the desired colour sequence directly onto the white layer of the film. Vehicle window graphics, e.g., are printed on exterior-mount film.
Interior-mount film, attaches to the interior surface of the glass. With some interior-mount films (ClearVue, 24-Vue), a mirror image must be printed (except for PosterVue, BannerVue and RetailVue), with the colour sequence printed in reverse, followed by the application of a white overall coat and then a black overall coat (ClearVue only). Window graphics for retail stores are sometimes printed on interior-mount film to prevent vandalism and to minimize weathering.
6. How do I know which Clear Focus One Way Vision film to use?
It depends on several factors, including the printing method (see above), what the graphic will be used for, print volume and desired life span. For low to mid volume, short runs, one-offs and proofs, digital inkjet printing is commonly used. For longer, high volume runs, screen printing is usually more cost-effective.
The quality and type of inks used will largely determine the quality and durability of the printed image. For short-term applications (6 months or less), screen printing or aqueous ink is usually sufficient. For long-term applications, solvent or other durable outdoor inks, including latex and UV-cure are recommended.
Some Australian state authorities i.e. transport and police departments require at least 35% visual light transmission on passenger motor vehicles. Our SuperVue, JetVue and AutoVue films have been independently tested for visual light transmission and are the only films in our range that are legally available for use on passenger cars.
7. Do I need to laminate the window graphics?
It depends on desired life span, as well as whether the graphics will be subjected to weathering, including rain. The main reasons for laminating perforated window graphics are:
1) to protect against UV, weathering, vandalism, dirt/dust etc. and increase the lifespan of the graphics;
2) to add gloss to enhance the graphics’ appearance; and
3) to maintain visibility through the film by preventing the holes from filling with water when it rains.
If it is laminated, it is easier to clean.
8. Is Perforated One Way Vision film easy to install?
Using a few simple tools and following some basic rules, One Way Vision window graphics are easy to apply and remove, allowing media to be changed as often as desired. For graphics that are larger than A1 in size (approximately one square metre), we recommend to engage the services of a professional installer or sign maker. For installations higher than 2m from the ground or access from the footpath, you may need a permit from the local council.
