Oxy-Dry
Anti-Offset Powder |
| Q: |
My
job offset (either fully or partially) and I was running my powder
sprayer at the normal setting. What's going on?
|
| A: |
Check the sheet for powder application
with a floodlight. Uneven powder spray patterns indicate a clogged
sprayer or wind turbulence that could effect application.

| Q: |
Frequent
blanket washing is required when I back up my work. Why is this?
|
| A: |
Try to use a smaller quantity of a
larger micron size powder. The balance between too much and too
little is important.

| Q: |
My
powder is lumpy and is sticking in my spraying device. Is the
powder bad?
|
| A: |
Powder storage is underrated. It should
be stored in a sealed container (moisture tight) and should be
kept off the floor where lower temperatures cause it to absorb
moisture.

| Q: |
Why
do I get bombing in my delivery? Is it a powder problem?
|
| A: |
Accumulation of excess powder in the
delivery will occur. Regularly clean the various press parts which
collect this excess, especially the spray head itself.

| Q: |
My
powder is not sticking to the printed sheet. What can I do to
get more powder to stick?
|
| A: |
Adjustment of the blow down bars and
fans may be required. On critical jobs you may have to slow the
press down. Make sure that electrostatic is functioning.
