MAGIC® APPLICATION GUIDE
DMBPC12 UNIVERSAL POLYCARBONATE BACKPRINT FILM
magic
MAGIC® DMBPC12 is a 12 mil backprint polycarbonate 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 polycarbonate surface protects the image while its texture naturally diffuses light and cuts glare. The stiffness of the polycarbonate base makes it easy to slide into display boxes or to make panels for rigid displays. DMBPC12 can be used with most dye-based inks for frontlit ant backlit applications.

APPLICATION GUIDELINES
Printer and Ink Compatibility:
The material can be printed with Hewlett DesignJet, Encad NovaJet, ColorSpan Displaymaker and water-based piezo printers. The recommended inks are as follows: Hewlett Packard dyes, Encad GS & GA and ColorSpan Wide Gamut inks. Using water-based pigments, such as HP UV, Encad GO or the water-based piezo pigmented inks will usually yield good print quality and light stability but expect lower transmitted and reflective ink densities than most dye-based inks. Dye-based inks are not light stable and will fade more rapidly over time. Inks NOT recommended for use are Encad GX, Ilford Archiva and ColorSpan EnduraChrome, because premature fading may occur.

Imaging:
The print side is the matte side and it is wound to the outside of the roll. Images need to be mirrored imaged.

Printer Loading:
When loading DMBPC12 disable the printer cutter mechanism. Most pruinter cutters are not sharp enough to cut through the 12 mil film. When used in the HP 750 series printer, material should only be sheet fed.

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. For HP 2000/3000 series printers, the recommended media selection, when running dye-based ink is ″Backlit″. The ″Photo Imaging″ mode should be used in HP5000(dye). Recommended printer setting for the 750 series printers is ″Heavy coated paper″. ″Super″ and ″Bi-direction″ are the recommended printer settings for the water-based piezo printers.

Water Fastness:
Pigmented inks have excellent water resistance when used in conjuction with DMBPC12. Dye-based inks have a moderate level of water resistance. Condensation in a light box can cause small amounts of ink bleed. Lamination with edge sealer is the best way to ensure complete waterfastness.

Light Stability:
Pigmented inks will offer greater light stability. For those applications where dye inks are used, it is important to overlaminate the imaged side shortly after imaging to prevent image fading.

Material Handling:
After printing is completed, material should be completely dried before handling. Wet or damp ink can leave the printed surface susceptible to being easily scratched. Condensation, inside a light box, can cause some ink bleed. Lamination and encapsulation is the best way to insure complete waterfastness and increase light stability.


FINISHING RECOMMENDATIONS
Mounting:
If mounting polycarbonate to any white backing film, it is essential to follow these guidelines or polycarbonate film coating delamination can occur. It is recommended to laminate in an environment less than 55%RH. Lamination failure may happen if materials are exposed to high relative humidity. Heavy gauge materials can delaminate or shrink over time, so pretest all films. After lamination the image should lay flat for at least 12 hours to ensure maximum adhesive curing and bond strength. It is not recommended to roll laminated prints into smaller than a 12″ diameter tube, as this can stress the lamination bond and cause splitting of the laminated layers. If trimming laminated material, trim by cutting and penetrating through the back side of the vinyl. A rotary cutter provides the best results. When hand trimming, the knife should be kept absolutely straight. Blades should be new. Angle cutting can cause delamination. Do not use a cutting mat. This soft underbody makes it more difficult to hold the blade straight.

Lamination:
Cold pressure-sensitive overlaminates are recommended. For additional lamination tips, see ″Lamination Tips and Tricks″.

Image protection:
Print a mirror image of the graphic on the matte side of the product and view from the film side. This protects the inks imaged on the surface in the light box, exposing the durable polycarbonate 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 slightly lower ink saturation than transmitted light.
