Static Frames?

[3Deep]

I still buy static frames from different companies, my question is what is the norm on newtons on those type frames 15, 20, 25 etc that you have bought.

Last three orders I placed I returned right away. Everybody promises north of 20 N/cm. None of them were delivered like that.

Switched to Newmans and now I can control the tension.

When considering static frames, the specs of the particular mesh used on the frame is what's important. The amount of newtons the screen is stretched to should be in direct relation to the mesh's thread diameter & % open area &  ink volume. To achieve optimum performance of the particular static screen you are paying for, it should be stretched to the manufactures spec. The mesh's elongation properties must also be considered so that after work hardening, the tension fall's within the optimum %open area, whether it is 15, 20, or 25 newtons.  This can only work if you know the characteristics of the mesh and trust that the supplier does too. Another way to control this however is bringing the stretching in-house. And I figure it is simpler to stop and start over on retentionable frames than it is on static glue frames.

I bought almost 200 of them over a few years and the highest I ever recorded was 22 newtons.  The vast majority of them were in the 12-16 newton range after a few runs through production and I have kept the 10 out of all of them that were 18 or above.  I bought from several different suppliers and they were all the same.  I haven't bought any in several years though so maybe they are better these days.
