"He who marches out of step hears another drum." ~ Ken Kesey
Just a note on exposure units.In general, a fluorescent unit with a proper vacuum lid, will usually produce better detail than a single point light unit without.It is the single most important component of an exposure unit doing high detail stuff.I once saw the figures and the difference in pressure (which translates to contact) between vacuum and compression or weights was well over ten fold.Maybe someone here can do the math comparing a vacuum lid's psi to fleetee's 30 lbs of water.Now, fleetee, don't get me wrong, one can do a lot with a compression lid or even weights but...
hey guys, are the higher mesh counts limited to high detail designs? for example can a 280 do a design that is meant for 110 or 160 design? another way to ask the question would be can a design that can be successfully done on a 110 or 160 also successfully be done on 280 or even a 305? the reason why I am asking is because I am ordering a big bulk of screens, and now knowing that the lower mesh count can not only do half tones but also cant do detailed designs like i attached on the op, i much rather spend a couple extra dollars on the higher mesh counts if that means that the mesh counts can be more versatile and buy 200/230/280 mesh screens so that they can do both the very detailed designs AND the simple designs.

how long do you guys dry your emulsion before burning a design on it? I made my own screen rack and have 2 fans on one side and 1 fan on the either. i know the emulsion gets dried in 2 hrs but im wondering if i can shorten that drying time

What criteria established this? Especially, what designs (and ink combo) do you think are meant for your 110's? I think that you almost need to order one or two each of the common mehes and see for yourself. See how much ink is deposited. See if all inks act the same.See of fine detailed that's reversed out fills in.You need some hands-on experience because, as your current screen inventory shows, I think that you have relied and acted upon some questionable advice.
Does anyone have any good videos, articles, charts, etc that they know on the top of their head that they can share with me
I just asked a question to someone else about vacuum vs weights on exposure unit. What does the data say? Does data exist? What is the pressure difference between vacuum exposure unit vs weight/foam unit?ThanksSent from my iPhone using Tapatalk
