PRINTING

To set up for printing, we will have to decide how many stations we need. The number of colors in our

label will determine this. Each station is set up exactly the same. The following set of guidelines will enable
you to set up and print in a very short period of time.

1. First place the print adjustment bearing block onto the print cylinder shaft, opposite the gear. Place

the drive side bearing block on the gear side of the print cylinder. Before sliding on the print cylinder, put one
spring plunger on each rod. Holding the print cylinder with both hands, slide the bearing blocks onto the
print guide rod until the print cylinder gear and the anvil gear mesh. (See illustration on following page).

2. Next, slide the impression adjustment blocks onto the print station guide rods and tighten the set

screws. Place two spring plungers on each guide rod, slide the ink fountain onto the print station guide rods.
Push the fountain toward the print cylinder holding the fountain firmly. Slide a fountain adjustment collar
onto a guide rod. Lock down the adjustment collar by turning the set screw on the side of the collar. Repeat
this on the opposite side.

3. At this point, the gear on the print cylinder and the gear on the ink fountain may not mesh. The two

nylon adjustment screws are located on the adjustment collars. Turn these clockwise until both gears mesh.
With the machine running, slowly turn the nylon adjustment screws in until ink begins to transfer from the ink
roller to the printing plate. NOTE: It is important that the fountain be brought in squarely. Advance the
screws until the print appears on the paper. You may now adjust the screw until clean, crisp print appears
throughout the impression. Repeat this procedure for each print station.

After completion of print set-up;

Blowers for drying of the ink may be placed between stations, four may be used. Four blower heads are
located in a storage rack on the back of the machine. Remove blower head from storage rack and place
between print stations. Align the pins on the head with the holes in the blower mount blocks. With blower
head in place, run machine before turning on blower switch (aux. 1). Only use as many blower heads as your
application requires. Use of all blowers when not necessary may affect the performance of the ink.

NOTE: The above instructions are designed to explain print set up only. The following instructions will

dwell on proper registration, set up and running registration, along with the fine adjustments that may be
needed to achieve quality print.

FOLLOW THESE INSTRUCTIONS AND ILLUSTRATIONS CAREFULLY. THIS WILL ALLOW FOR

QUICK SET UP WITH MINIMAL WASTE.

Now that we have established how to get print onto our stock, it will be necessary to register the print both

along and across the web. This particular phase of printing will require some patience and practice.
However, by following the list of instructions and illustrations, you will be printing quality labels in only a short
time.

All print registration will be done in conjunction with the first print station (bottom). This particular station

remains as a constant for all registration. Run the machine slowly and engage the ink fountain. Move the
ink fountain inward using the adjustment collars until uniform covering is observed across the printing plate.

NOTE: Excessive ink fountain pressure against the plate may cause damage to the printing plate. In

order to achieve uniform impression, adjustment to the print cylinder adjustment blocks may be necessary.

NOTE: If at this point you are printing only one color, you should now set the cutting die. The next steps

will explain how to set the rotary cutting die.

CAUTION: Keep hands and loose fitting clothing away from all moving parts on this machine. Always

turn the machine off when making adjustments.
