Zebra Premier PVC, 10 mil Adhesive back w/Mylar backing (5 packs/100) Zebra cards give you image sharpness needed for vivid colors and detailed, readable bar codes. Poor quality cards often have uneven surfaces and burrs that reduce print quality and cause printhead damage. Zebra guarantees its pure PVC and Composite PVC cards to be compliant with ISO standards, dust-free, and have smooth edges, giving you better print quality every time. For more demanding security applications, make your cards more tamper resistant and secure with Zebra\'s custom embedded holograms, color shifting ink, opacity marks, pre-printed microtext or UV images, and custom designed cards. All these card options are available from your Zebra reseller.
