Screen Printing

Screen
printing is an affordable way to get your design onto t-shirts, hats,
coozies, and golf towels (just to name a few available products).
Our
Screen Print Department utilizes state of the art screen printing
techniques. Whether you need just a one color print or index printing
with spot colors, we can provide it.
Screen printing utilizes color separations to create the
finished image. A one color print job will use one screen during production,
while an index print will begin with 4 screens with a new screen added
for each spot color. Dark fabric requires an under base of white ink
for bright colors. Much like a highlighter on black construction paper,
if yellow is printed directly on black it will almost totally disappear
into the fabric. the white under base allows the yellow to show vividly.
In short, dark colored fabrics require a white underbase to make colors
visible.
The artwork for each screen is printed onto a polyester film that allows
light to pass though the unprinted areas. A silk screen is coated with
a special photo reactive chemical called emulsion. After it has dried
it is then exposed on a UV light table with the artwork for each color
separation. The exposed emulsion becomes non-water soluble, while the
unexposed image areas wash out of the screen. The open areas of the screen
are where ink will be able to pass through. The screen is lined up on
the press and printed onto the medium. Then the printed article is sent
through a heater at about 400 degrees to cure the ink. Items that cannot
withstand the exposure to high temperatures cannot be screen printed,
these include bags with thin nylon straps and cheap plastic buckles or
handles.
