Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
I read that as 15 over the target tension, then it would settle.I read an article some many years back about hitting a freshly stretched screen with a very high pressure pressure washer - about 5k - This releases the stored tension in the knuckles of the mesh as if you were pulling a squeegee over the fabric multiple times - MASSAGING- the tension out of the knuckles. After hitting it with the pressure washer they would go back and tension it up again.If you are printing with much lighter pressure now jvanick, you are "lightly" massaging the knuckles, which is why you are seeing tension readings drop slower.You need to get back to shiatsu massages
for as much of a screen junkie that i am.. i just make the screen and put it into production. no fancy tensioning trick with on/off up/down wait a min .. just wack it, lock it clean it coat it shoot it tape it print it. Here are my tricks.. 10 mins from frame to tape with bolt mesh. https://youtu.be/YMcKjQAr988
that shop was all cost driven. never retensioned and treated the screens like crap. id show up every couple weeks and restrech a dozen with cheap economy bolt mesh. wacked it to 40 and it would settle down to 25 after a couple runs.
I stretch and retension 280 s mesh. I always stop at 24n with the rollermaster whether new or retension because they reach their max of 28 by the time I tighten the rollers.
