MAGIC® APPLICATION GUIDE
DMBP5 UNIVERSAL INK JET BACKPRINT POLYESTER FILM
magic
MAGIC® DMBP5 is a 5 mil backprint polyester film which can be used in all Encad NovaJet® ColorSpan®, Hewlett-Packard DesignJet® and water-based piezo wide format printers. By reverse imaging on the matte surface, the polyester film surface protects the ink jet image. DMBP5 is ideal for durable backlit display signage.

APPLICATION GUIDELINES
Imaging:
The print needs to be reverse (mirror) imaged and viewed from the gloss side. The print side is the matte side, and it is wound to the outside of the roll.

Printer settings:
To optimize print quality, printers should be set for highest print quality. The maximum ink saturation level for NovaJet and ColorSpan printers is 350%. To reduce the effects of the ″star wheel marks″ and to minimize bleed, the recommended maximum ink saturation level is 225% on the HP 2000 and 3000 series printers. The media selection is ″Backlit″ for the HP 2000 and 3000 series printers. ″Heavy coated paper″ is the printer setting for the 750 series printers. ″Super″ and ″bi-direction″ are the printer settings for waterbased piezo wide format printers.

Printer and Ink Compatibility:
The material can be printed with most water-based pigmented and dye-based inks. It can also be used on water-based piezo wide format printers with pigmented ink. Using water-based pigments will usually yield good print quality, but expect lower transmitted and reflective ink densities than with most dye-based inks. Inks not recommended for use are Encad GX, Ilford Archiva and ColorSpan EnduraChrome, because premature fading may occur.

Waterfastness:
Pigmented inks have excellent water resistance when used in conjunction with DMBP5. Dye-based inks have a moderate level of water resistance. Condensation in a light box can cause small amounts of ink bleed. Lamination with encapsulation is the best way to ensure complete waterfastness.

Light Stability:
Pigmented inks will offer greater light stability. For those applications where the dye inks are used and long term light stability or sunlight transmitted through windows is an issue, the material an be printed right reading and a UV stable, vinyl pressure sensitive overlaminate can be applied to the printed surface. The material should be installed with the UV stable laminate side facing out. For total protection, both sides of the graphic should be laminated with UV stable laminates.


FINISHING RECOMMENDATIONS
Image Protection:
Print a mirror image of the graphic on the matte side of the product and view from the gloss film side. This protects the inks imaged on the surface in the light box, exposing the durable polyester film surface to any outside elements.

Lighting:
to optimize image appearance, the image should be back illuminated, as the transmitted light yields the desired ink densities. Viewing with reflected light yields only slightly lower ink saturation than with transmitted light.

Lamination:
Cold pressure sensitive over laminates are recommended. Heat activated laminates are not recommended unless the image is encapsulated with a 1/8″ safe edge around the entire graphic.
