latch clamp The mechanical device used to join the front screen holder assembly against the head front end
plate.
L.C.D. The liquid crystal display.
locking cam A machined cam milled in such a fashion as to lock two mechanical surfaces against one anoth-
er when turned in a specific direction. Locking cams are used to secure printing pallets to the index support arm
assemblies.
main image The defining color of a design. (In some cases one or more colors/films may be needed to create
a defining complete image.)
main regulator The first air pressure regulator which the incoming compressed air encounters, located on the
bottom of the machine.
manufacturer’s rating plate The plate on which a manufacture will state the power requirements and ser-
ial and model numbers of a machine.
mesh count The number of openings per linear unit of measurement, either per inch or per centimeter, of a
screen printing fabric.
mesh tension The force tending to produce elongation or extension at which the screen printing fabric (mesh)
is exposed to, expressed in nanometers.
message code The systematically arranged and comprehensive collection of statements to convey a mes-
sage.
micro registration The incremental adjustment or placement of a screen.
no shirt detector The photo eye sensor that will allow the machine to determine if there was no T-shirt place
at the load station after the machine has gone through an index cycle.
O.D. The outside dimension.
off-contact The preset distance between the bottom of the screen fabric and the top surface of the substrate
that is to be printed.
off-contact lever A mechanism designed to allow the adjustment of the off-contact of all screens at a single
point.
Ohm Meter The testing device used to check the resistance across an electrical conductor.
oiler The device used to supply a mist of oil to the compressed air utilized by the machine.
operator interface The circuit that permits communication between a central processing unit and the
Operator of the machine. The LCD control panel provides this interface.
operation mode toggle switch The electrical device used to command the machine to start an index cycle.
optical distortion The effect of viewing layered films at differing perspectives.
outboard speed The speed at which the print carriage moves from the center of the machine towards the out-
side.
pallet The flat surface on which the substrate is placed to be imprinted.
Pelon A material used to sample prints during set-up and registration of the press.
pin bars A flat piece of stainless steel containing small dowel “Pins”, manufactured under high tolerances so
that there is zero play between the pins and the corresponding pre-punched acetate carrier sheet.
PLC memory The program within the programmable logic controller.
press head The mechanism used on the machine to push the ink through the screen.
press registration The capability of the equipment to repeat print location and alignment from color to color
and pallet to pallet. Press registration is an extremely fine adjustment which sets the distance between the center
of pallet arms to a tolerance of plus or minus .001”.
