Conducting the Tape adhesion Test (continued)

Step Procedure

4

Visually examine the card and the strip of tape pulled from the card, to see if
any portion of the 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 Film particles (a) pull away from the card and (b)

adhere to the tape, this indicates that inadequate adhesion of the 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.

• Once the temperature has been increased 4 times (20 degrees), reset

temperature to default and increase the Dwell Time by .5 second.

• Repeat this process until adequate adhesion is achieved.
• Ensure that the cards (in use) have a surface roughness (Ra) of 60 micro

inches or less.

This information should be available from the card manufacturer.
