Today many people print full color edge to edge on their technology cards. This can be very challenging when using a Direct To Card printer.
PVC cards are typically manufactured by laminating 3-5 layers of PVC under
heat and pressure, using a hydraulic press. Contactless and proximity cards
have a die-cut PVC center core with an area punched out to receive the
embedded coil and IC chip. The center core is sandwiched between a top and
bottom white PVC layer. An additional clear PVC layer may be added when the
top and bottom white PVC layers are pre-printed.
PVC is used because it is the best material for dye-sublimation printing, and also
because it laminates into a contiguous piece of plastic, which does not delaminate
Because PVC tends to flow during the laminating process and the embedded
components remain rigid, surface discontinuities can result from a basic
tendency of PVC to mimic the topology of the embedded item.
Some information to consider when printing on these types of cards:
You must be willing to print test cards and may be required to make changes in layout or content to obtain the best results.
Do not print a bar code or text in the area of the antenna

Contact Chip Card:
You should only print on the back side of a contact chip card with a direct to card printer as the contact chip can scratch your printer’s print head and cause damage that would not be covered under warranty.
