I am looking into buying a new kind of exposure unit and from my research i have found like dozen diffrent kinds. So what kind should i get i need sumtin decent not highly over priced but im willing to spend money or even build one. Also it would have to be able to burn bigger screens ( up to 25x36)with good detail...what do u guys suggest
the sun burning method seems compicated from what i read how do u guys do it
foam pad to fit inside screen, thicker that frame. black cloth or paper on foam
coated screen face down on pad so it is suspended
posi face down on screen
glass on positive, weights down posi/screen onto pad
Hold square to sun.
depending on emulsion and mesh color and location on the earth/strength of sun, exposure takes from 30 sec-90 seconds in full sun, longer when overcast.
wash out with waterspray with garden hose or in washout tub.
I use a light integrator to time the exposure although we did a few last weekend in a course with a watch, cause the lady wanted to do it at home and see how it would work. took 90 seconds on white mesh, it was cloudy, but had a bit of a shadow.
