Laminate Film Education

Digibond films are made especially for digital toner presses such as Xerox, Konica, and Nexpress. Prints from an HP Indigo Digital Press do not require Digibond adhesive.

 

Laminates with standard adhesive work best for HP Indigo Prints. DigiBond adhesive won’t bond well. The digital laminate, DigiBond,  is for all other digital toner presses like Xerox, Konica, Nexpress, etc.

Many times the machine cannot give enough pressure to squeeze down the limited amount of glue on a 1.2 and it creates “silvering” or tiny air pockets under the surface.  On Heated Shoe machines, the laminate cools too much if it is 1.2 mil so it doesn’t adhere well, whereas the 1.7 and thicker can retain the heat to have good adhesion to the sheet.

Less is always better in tension and rewind – suggest starting under 5psi or 0.5 bar.

For thinner stocks, less pressure is better to keep from buckling the paper and a good starting point on good rollers is generally 10-20 PSI or about 1 bar.  On thicker stocks, a good starting point is 40 psi or 2-2.5 bar.

Typically BOPP or biaxially Oriented Polypropylene product will change shape with more heat and tend to shrink from ¼” to 1” depending on how hot it is run.   This is only applicable to thinner laminates – from 1-1.5 mil.

This could be a combination of too little pressure or too much heat.   The first is called silvering and is when too thin of a laminate is used or the machine has worn or soft rollers.  The second it simply the heat “boiling” the ink or toner causing gaseous bubbles under the laminate.

SHR™ stands for Silver Halide Replacement and means that there is now a smarter, more environmentally sound and lower-cost way to produce photos that have the look, feel, and weight of regular photo paper.

SHR laminate film is best ran between 170°-  225°F or 70°- 105°C.

PlatinumGS laminate film is best ran between 230°- 260°F or 110°- 125°C.

PlatinumNYLON laminate film is best ran between 210°-  230°F or 100°- 110°C.

PlatinumPOLY laminate film is best ran between 230°-260°F or 110°-125°C.

PlatinumPET runs between 230° – 260°F (110° – 125°C).

Platinum™ is run anywhere between 210° and 270°F but it depends on the exact type of film. Please refer to the list below:

  • Platinum PET: 230° – 260°F (110° – 125°C)
  • Platinum POLY: 230° – 260°F (110° – 125°C)
  • Platinum NYLON: 210° – 230°F (100° – 110°C)
  • PlatinumGS: 230° – 260°F (110° – 125°C)
  • SHR Photo Laminate: 170° – 225°F (75° – 105°C)
  • Stamping & Sleeking Foil: 210° – 230°F (100° – 110°C)

A+ School Gloss laminate film is best ran between 285°-  310°F or 140°- 155°C.

OPP Matte, Karess OPP Matte and all PET Matte films are safe for food contact.

Sleeking™ is a digital print finishing method that involves a special image transfer that specifically bonds to HP® Indigo® ink and other digital inks on many printed surfaces, allowing the ability to create dynamic special effects and designs.

Similar to foils, but infinitely easier and at a much lower cost, Sleeking™ technology can apply a finish, such as gloss or matte, a metalized background, such as gold or silver, or a dramatic holographic impression in spot locations or full coverage.

Matte laminate is typically coated or etched, adding a special process or coating to it.  This offline (sometimes) process, along with the fact that there is much less of this product used as opposed to gloss, makes it that much more expensive

Stamping and Sleeking foil are best ran between 210°-  230°F or 100°- 110°C.
