5.2.25.3 Printer adjustment
Before completing the AVS test on a printing machine, the machine maintenance history
should be checked and any remedial work recommended is completed.
Step 1: Paste Preparation
First, 5 prints in each direction should be completed without AVS measurement. This is to
prepare the glue and stabilize the squeegee pressure, to ensure good consistent prints for the
test.
Step 2: Adjust (Theta)
Now make min. 4 prints, 2 in each direction, Front to Back (Reverse direction) and Back to
Front (Forward direction), obtain (Theta) rotational error correction, which are then applied
to the machine.
On the following steps during X/Y adjustment, check the theta to make sure it is stable.
Step 3: Adjust X/Y
Now make min. 4 prints, 2 in each direction, Front to Back (Reverse direction) and Back to
Front (Forward direction), obtain (Theta) rotational error correction, which are then applied
to the machine.
On the following steps during X/Y adjustment, check the theta to make sure it is stable.
Step 4: Perform MCT
Mark the first measurement that you would like to measure in the stable measurement se-
ries, e.g. by writing "Start MFU" into the comment field of the measurement.
From this measurement, you must perform at least 20 measurements (10 in each direction).
Parameters for printer adjustment in AVS Software
The main parameters what can be adjusted on a printer during a MCT are:
X-Offset: as a result of the AVS measurement
Y-Offset: as a result of the AVS measurement
Stencil rotation (Theta): as a result of the AVS measurement
Print speed: determined by the evaluation of the printing quality.
Print pressure: determined by the evaluation of the printing quality.
Separation distance: determined by the evaluation of the printing quality.
Separation speed: determined by the evaluation of the printing quality.
NOTICE
Use USC – Vac/Dry if possible.
Use Dry with OSC using cyclone cleaner system!
