printing is a method used to transfer ink onto
a part. The advantage to using screen printing technology
is that you can print 360 degrees around a cylindrical
shape in one application. You can print items as small
as a lipstick container and as large as a 5 gallon pail.
You can print on flat surfaces as small as a match box
or as large as a billboard sign. You can print on oval
surfaces as small as a bottle of nail polish or as large
as a shampoo bottle.
WHAT IS SCREEN PRINTING?
Screen printing is a wet process where ink is squeezed
through a fine mesh material onto the part to be decorated.
a film positive is made of the artwork, this film is
then laid over a fine mesh material which has been tightly
stretched and fastened to a frame. The mesh material
has been coated with a light sensitive emulsion and
the film and screen are then exposed to a mercury vapor
light. This exposure hardens the emulsion on the screen
creating a solid barrier. The portion of the screen
that was covered by the film positive remains soft and
is washed off the screen with a pressure hose and water.
The completed screen now allows ink to
pass through this washed out area while preventing ink
from passing through the hardened emulsion. This washed
out portion of the screen is now an exact duplicate
of the artwork to be placed on the part.
The screen is then mounted in the screen
printing machine and clamped in place. A fixture is
mounted under the screen which is designed to hold the
part to be printed in the correct location. The part
is then placed in the fixture and ink is added to the
screen. The ink is squeezed through the screen with
a rubber squeegee while the part is moved under the
screen, allowing the ink to be placed on the part.
FLAT SCREEN PRINTING
In the case of a flat part, such as a ruler or CD case,
the part remains fixed as the ink is squeezed onto the
surface. Mystic has several semi-automatic screen printing
machines capable of printing items as long as 24 inches.
By changing screens and re-registering the part, multi-color
print applications can be achieved.
Mystic has fifteen semi-automatic screen printing machines
and two automatic machines capable of printing single
and multi-color images on cylindrical parts. All our
machines are equipped with inflation systems that allow
us to inject air into the bottle while it is being printed.
This enables us to print on soft sided bottles made
of polypropylene or polyethylene. These machines are
excellent for printing on items such as round cosmetic
containers, syringe barrels or glass bottles.
OVAL SCREEN PRINTING
All of our screen printers have been fitted with special
tooling which allows us to print on oval applications.
As in our cylindrical screen printing, we have inflation
devices that allow us to print on soft sided bottles.
We can print either single or multi-color applications
depending on your requirements.
HIGH VOLUME AUTOMATIC
For those large run jobs, Mystic has a three station,
high speed machine capable of printing on ovals or rounds
up to three colors at a rate of three thousand pieces
per hour. This machine is also equipped with two pressure
sensitive labeling heads which provides us with the
flexibility of printing and labeling in the same application.
We have the ability to print on many substrates
• Plastics –
including polypropylene and polyethylene
• Metal – including
stainless steel and powder coated aluminum
We also provide in-house flame treatment of materials
when needed. We use UV and solvent based inks as well
as specialty inks used to print on glass, polypropylene
and polyethylene parts.
We can print on various shapes
