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.
