A SERVICE TECHS OBSERVATIONS ON THE SLEEKING PROCESS

Registration Many things are happening during the sleeking process that changes the size of the paper.  Some people will say the sheet grows as it runs between the heated rollers of the digital press or laminator.  The heat and pressure rolling it out like calendared plastic. Others will say no the sheet shrinks as the fibers are being dried out, as the heat and pressure wring the moister out of them. It could very well be both are true.  This could very well be what environment you print in.  Wet or Dry, what is the moisture content of the...

Tips for Sleeking Successfully

Registration There are many things that happen during the sleeking process that can change the size of the paper.  In some cases, the sheet grows as it runs between the heated rollers of the digital press or laminator, or the heat and pressure rolls it out like calendared plastic. At times, the sheet shrinks as the fibers are being dried out, and  heat and pressure wring the moisture out of them. Multiple factors can affect this, including the environment you print in.  Is it wet or dry? What is the moisture content of the paper?  What is the force...

Is Your Laminate Not Sticking? A Look at Film Adhesives

First, let’s have a look at the components of a printed piece before we discuss applying laminating film. Stock – Paper stocks have different textures and levels of acid content in addition to varied thicknesses. Toner vs. Ink – Printing machines use either powdered toner (dry) or fluid ink (wet) to add an image to the stock. Whether you are using an oil-based media or not is also important to consider. Heavy vs. Light Toner Coverage: When you print using a high amount of toner coverage, for example, a full-color brochure with a full bleed, maximum adhesive strength will...

Polyethylene Terephthalate

Also known as polyester, PET, and PETP, this laminate is the most common of the thermoplastic polyesters. Calling it “polyester” often causes confusion – not only is it chemically similar to PBT also a thermoplastic polyester, the most common resin system used in GRP is also a polyester system – and also often called just “polyester”. (In this latter case, however, the polyesters are chemically unsaturated and are “free-radical polymerized” into a thermoset). Polyethylene Terephthalate is a strong and hard, stable material that absorbs very little moisture. It offers excellent gas barrier properties as well as chemical resistance with...
