PVC
is a rigid and a versatile polymer and for several of its applications must
be compounded with plasticizing agents. It is a relatively inexpensive
material that has several forms and can be made into many different items,
including flexible PVC, liner material PVC, reinforced PVC, ridged PVC
plastic, and PVC pipe.
Printed PVC film is printed with written or graphic matter. They are also
printed with symbols and logos. These films are designed for ink jet
printing. There are three main steps to producing a drop with thermal
technology.
- The chamber holding the ink bubble is heated.
- The bubble bursts due to heat and the ink drop shoots out of nozzle.
- Finally, the vacuum from the drop leaving the chamber draws the next
bubble into the chamber.
There are 300 to 600 of these firing mechanisms per print head. Four
to eight of these tiny drops are fired onto the film to make a color dot.
Larger dots of 35 picoliters are usually created with black inks. part of
this difference is that the colors are usually created with dye-based ink
and the black ink is a pigment based ink.. dye-based inks produce a wide
range of vibrant colors whereas pigment based inks are more durable and
water resistant.
