GV428P is a 3.2 mil matte white, soft calendared PVC film designed for solvent and UV inkjet printing. The product is coated on one side with a permanent, opaque, acrylic pressure sensitive adhesive with air egress technology and supplied with a 98# polycoated liner. GV428P is designed for indoor or outdoor medium-term advertising and promotion applications on flat or simple curved surfaces. Use of PERMACOLOR® LUV or RAYZor™ overlaminating films will extend the life of the graphic. GV428P is also a great for bubble-free applications of indoor wall murals.

Approved Print Methods:
UV Inkjet, Eco-solvent, True Solvent, Latex
To achieve the best possible print quality, please make sure that the correct ICC profiles or printer settings are used. Profiles can be obtained from our Distributors or can be downloaded from www.mactac.com/graphics . Printer and heater settings and ICC profiles can also be downloaded from some O.E.M. or software manufacturer’s websites. The ICC profiles are provided solely as a customer resource. Print environments, the individual nature of printing systems, inks and software can significantly affect output.

DURABILITY:
The outdoor durability of the unprinted film is 4 years. Overlamination of the inkjet-printed material with PERMACOLOR overlaminating films delays color fading that may occur over time. Color fading is mainly dependent upon the inks quality (see technical data sheets given by the ink manufacturers) and pressure sensitive media being used.

RECOMMENDATIONS:
Always test your combination of B-free Gruv products, inks and laminating films prior to commercial use.

1. Printing Conditions: Print in conditioned pressroom at ±73°F (23°C) and 50% RH. The maximum allowable ink saturation is 270%.
2. Drying Step:It is critical the GV428P print is properly dried prior to cutting, lamination or application. We strongly recommend leaving the print open to the air (not rolled up in a tube) for a minimum of 24 hours prior to lamination or application. Residual solvents in the vinyl and adhesive will negatively affect the bubble free properties of the adhesive and can cause a significant build, or loss, in adhesion resulting in potential substrate or graphic failure and/or more residual adhesive being left behind upon removal. Additional hot air drying or IR drying will speed up the drying process and shorten the overall drying time.
3. Laminating Conditions: If the printed graphic is likely to be exposed to corrosive liquids, smoke, fumes, and highly polluted areas or there is a likelihood of scratching, it is highly recommended to laminate with Permacolor LUV Series overlaminating films.
4. Not recommended for surfaces including, but not limited to rubber and plastic, aged paint (chalking) and metals (corrosion or oxidation), improperly cured paint, surfaces with poor paint-to-surface adhesion, over existing graphics that must remain upon removal, oily surfaces, unpainted wood, etc.
5. Application:See TA2032 Surface Preparation on www.mactac.com website – for specific application to dry wall reference TA2500. These can be found on the MACtac website under Technical Assistance Guides.
6. Transportation Conditions: To allow for easy transportation, B-free Gruv series can be rolled up, with the image out, with a minimum diameter of 6 inches (15cm). When the image is not protected by an overlaminate, make sure the print is completely dry and protected in a plastic bag. During transportation or storage, avoid exposing them to extreme temperature and humidity changes.
