Peter, I see their is the panelframe and the roller panel. I am looking into upgrading and would like to try them. What range of tension should I expect from each system?
Gerry: Great questions on target mesh tensions, but without having personal experience with the new mesh insert panels I'd hate to quote you specific numbers. My experience with the original launch of the Panel Frame system was that it was possible to achieve initial tensions in the 20N to +30N range dependant on the mesh count.
The problem was that mesh that used in the original Panel Frames was being sourced from a Chinese manufacturer, that provided very inconsistent results. There were a number of of reports of the mesh insert panels popping during the initial installation, and/or quickly losing tension levels after just a couple of reclaims. This was particularly prevalent with the higher mesh counts of 280T and above. It's my expectation, and something that has been backed up by Sefar that these problems have been overcome by utilizing Sefar mesh.
With that said, my own personal position is that if you have the money to invest, and the skills to properly use them that the Newman Roller frame provides the best quality print results of any frame on the market, bar none. I'm real interested to see the results people are getting with the Newman frames using the Sefar Mesh Panel Inserts.
So where do the TRAX frames (aka Panel frames) fit in? I see them as a good intermediate solution between static stretch and glue frames that can provide the small to medium size print shop with decent mesh tensions and the flexibility to have a wide range of options available through the ability to mix and match different mesh count panels as required. I'll reach out to the guys at Sefar this week to see if they have any specific numbers on tension levels and if they do, I'll post the info here.
