If your laminator delivers an adequate amount of pressure during the process, you can often use a standard film on a digitally printed job. Good pressure compensates for a weaker adhesive.
Depending on the type of ink/toner your press uses, this can influence your decision to use a
standard or digital film. Typically, Some presses have fuser oil in the toner. Which makes sticking to the ink more of a challenge so digital or Printaply Pristine Ultra film is recommended. Other digital presses use a more waxy toner which is easier to stick to so in some cases, a standard thermal film is ok.
Things to consider about your job….
Whats going to be done with the sheet once laminated?
How much ink coverage is on the sheet?
How thick is the stock?
How Long can I leave the Job before being laminated?
This one is a challenge in today's fast paced print market! In some cases, if the printed material can be left overnight, this allows unwanted fuser oils etc… to dissipate giving film a better chance of sticking.
