"The reference to 30n is for conventional and a good place to be for volume shops who don't perform routine maintenance.
40 and up if for serious players who dedicate time to their screens.
60n is for masters as the handling requirements and press tolerances are beyond the scope of 99.1% of the printers out there."
This is a quoting John Sheridan in another post.
I am not doubting his wisdom, I would just like to know what you use in practice?
I have a stretcher that gets to 24n, by the time a prep the screen after taking it off the stretcher I'm at about 22, a few months of work, I turn my screens around quite a lot, I can be down to 15.
So I'm printing with screens from 15 - 22n. This is after I started checking and re stretching old screens, I used to work from about 8n up.
To print with high tension would be great but we have a really hard time stopping them from ripping, we use statics and I don't think statics can hold the tensions John is talking about.
