Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
What thread diameter are you asking about?Thin thread?Standard thread?Thicker newman thread?
What presses do you have?

I'm asking (if others are doing high tension well and how).To really answer you I would need to know the presses. As was mentioned earlier the higher you go the tighter the tolerances you would need to hold. Some presses would max out the ability to hold tolerances at say 20ncm. Others could theoretically hold tolerances for 40ncm+ screens.Only a handful of presses can hold the tolerances for any newton level above 30. Those would be Anatol Vindercator, MHM SA S2000 S3000 S4000 S5000 series presses. These are presses with massive platen arms that would take an elephant to deflect. I am in no way discounting any other press. Any press with a platen arm of say 3-5" by 1-2" simply will not hold the tolerances of say 40ncm screens over an extended period of the forces being exerted on them. Simple Physics. Next the amount of initial force needed to deflect the screen enough to release the ink raises almost exponentially as you raise the ncm.On a side note counter intuitive to what you would think higher newton levels can cause print issues on high detail prints. We are not printing a rosette pattern on a flat surface. We are for all practical purposes printing as with water balloons of color on a mountain range.
Fine. In 1995 I managed a shop that had nothing but Newmans. We kept 35ncm or better on all of the frames. We used the newman mesh as well as just about every other. I found the Dynamesh to be the most consistent. With that said the only thing I will say to you is Document Document Document. We had a log book that had all the particulars for every frame in production. Each frame was stamped with a number. The log had such info as tension; when re-tensioned; re-mesh initial, secondary and final tensions; number of impressions on each frame (total and curent). There were a ton of other parameters that were specific to that shop. Point being is it can be done but as with everything else in printing the more you track and document the better.

Very good info. I am fully on board with the documentation idea. Was it clear, that the higher tension did provide higher numbers over time? Did you happen to have that documentation kept? I know it's hard to compare unless you are running the same design the same way and for the same quantity.Do you think that 35n on S thread on all mesh, will provide even more...or the same as 40n reg mesh?
Starchild,I have no idea what you said, but it sounded cool. LOL.What's the low elongation part referring to? I only know of elongation (stretching) as a term for image distortions due to excessively low tension. What is a high module?Well, it's clear that if you have threads that hold higher tension, they open more, drop more ink, and as a result, you can print faster.
