i am a screenprinter and yes the screen will work but the mesh count is different than what they sell for hash. i use 4 to 5 different meshes. start with a coarse mesh like a 110, then get smaller next i use a 156 mesh,then 196 or 200 and finish with a 355 or 390
i tried this on last years trim and i am pissed i diddnt know about this sooner.
so many years of wasted trim that i composted
