How much tension does a screen usually loses
after being reclaimed ?
Any big problem in using reclaimed screens ?
It depends on how many impressions you made with the screen and how much printing pressure you were using. After 2or3 prints/reclaim/re-tension you should see very little tension loss and not have to re-tension again. The reclaim process alone won't cause tension loss.
Depends more on what thread/mesh count you have, how much tension you brought it up to in the beginnng. Example: We use 380/31 68x80 and take them up to 30 newtons. Same size screen on a 330/34 is going up to 33 or 34 newtons. On the 380/31 we can loose three/four newtons after the first print run, and reclaim. We would loose another couple on the second, and stabilize aroung 22 or 23 newtons. On the 330/34 we would most likely loose about eight overall and stabailize around 24 newtons. We use stretch and glue frames, not retensionables. We stretch using the rapid tensioning method.
