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 III). (Note:
The optimal transfer settings may vary from card type to card type.)
Important! 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.
2 Select the UltraCard IIIs-Glossy PVC if the card is glossy 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.)
4 Visually examine the card and the strip of tape pulled from the card, to see if
any portion of the HDP Film was removed from the card.
If any residue (e.g., oil or grease from fingertips) is present on the card
surface, the evaluation results may be affected.
If the printed, transferred HDP Film particles (a) pull away from the card
and (b) adhere to the tape, this indicates that inadequate adhesion of the
HDP Film to the card. Increased heat and Dwell Times are necessary to
resolve this problem.
Samples 1, 2 and 3 show a representation of the adhesion level you can
expect.
Result 1: Sample 1 shows a significant transfer to the tape and is an
absolute failure.
Result 2: Sample 2 shows that very slight transfer to the tape can be
acceptable without sacrificing overall image durability on matte finish cards.
Result 3: Sample 3 shows no transfer to the Tape and is an Absolute
Pass.
5 If the tape test indicates inadequate adhesion, increase the heat setting by 5
degrees, print another card and try the tape test again.
