Tri-Loc Pre-Registration System
The M&R Tri-Loc Registration System is designed to aid in
the set up and registration of screens on the M&R Gauntlet,
Terminator, Challenger and Formula series presses. The
system as a whole is simple to use. It starts by pre-register-
ing screens on the exposure unit, then transferring those
screens to the press, which is outfitted with a location fix-
ture that duplicates the exposure system exactly. This stop
location is accurately repeatable from print head to print
head, giving the press operator a quick and exact locating
point to set screens.The process is divided into three areas
as follows:
1. ART DEPT: “Film and Pin Register”
2. SCREEN DEPT: “Exposure Registration”
3. PRESS SET-UP: “On Press Registration”
As with any system of this type, it is important that everyone
involved has a through understanding of how their partici-
pation affects the overall accuracy of the system. It is rec-
ommended that everyone involved read these instructions
in their entirety.
SYSTEM COMPONENTS: (See Fig. 1)
EXPOSURE UNIT MASTER FRAME (Adjustable)
EXPOSURE UNIT MASTER FRAME (Non-
Adjustable)
ON-PRESS PALLET
PIN BAR
CARRIER SHEET (8.5” x 20”)
CARRIER SHEET (11.5” x 26”)
To better facilitate shops that have existing film/pin sys-
tems, the M&R Tri-Loc is offered without a film register Pin
Bar attached. Pin Bars and carrier sheets are available sep-
arately or in a start up kit available through M&R Sales and
Service. It is important to note that the greatest factor
affecting quick set ups and on press registration, is proper-
ly separated films that have been accurately registered to
one another using some type of “Pin Bar” system.
This method of pre-registration in the Art Dept. will have a
direct effect on the overall accuracy of the system once the
screens reach the press.
Because the system begins in the Art Dept., you will need
to set up a film/layout table in which to register your films to
the Pin Bar. This layout table must duplicate the image and
Pin Bar location of that on the exposure unit Master
Frame.The following pages will detail the steps needed to
set up a Film/Pin system that will carry through from the Art
Dept. to screen exposure, and ultimately to the press
mounted unit.
Art Dept. Set-up:
In order to set up a layout table for registering films, you
must first attach 1 Pin Bar to the exposure Unit Master
Frame as a reference for your film positioning. The dimen-
sions shown are for M&R supplied Pin Bars, but can be
used as a guide if you are currently using pin registered
films. (See Fig. 2)
NOTE: When mounting pin bars,
clean the mounting surface thor-
oughly to insure proper tape adhe-
sion.
