Conducting the Tape Adhesion Test
It is important to conduct Tape adhesion tests because Fargo cannot be certain which
transfer temperature and Dwell Time will work best (when printing cards other than UltraCard
or HDP-PVC). (Note: The optimal transfer settings may vary from card type to card type.)
Caution: Inadequate time and temperature could produce cards that are more
vulnerable to accelerated wear and dye migration. Use sufficient time and temperature to
transfer HDP Film to the card to ensure a long lasting, durable card.
Step Procedure
1 Test the adhesion quality of the HDP Film to the card by printing sample cards
and completing an adhesive tape test.
(Note: The Institute for Interconnecting and Packaging Electronic Circuits (IPC)
outlines a pressure sensitive tape test that evaluates adhesion quality. Refer to
their IPC-TM-650-3.7.1D test manual, Section 3.7, Number 1.)
2 Select the "UltraCards-Glossy PVC" if the card is glossy and print a test card.
OR
Select the HDP Cards-Matte PVC if the card has a buff, matte finish and print a
test card.
3 a. Apply a strip of ½” (12mm) wide Scotch-type clear adhesive tape (such as
3M brand 600), at least 2” (50mm) long, firmly across the surface of the card,
pressing out all air bubbles with a fingertip.
b. Remove the tape by smoothly and rapidly (approximately 2 inches/second
(50mm/sec)) pulling it up at a perpendicular (90 degree) angle to the card.
(Note: The IPC recommends a minimum of three tests for each card type
evaluation.)
