I as well.  I was looking for an "all of the above" option.

Artelf2xs:
Ok, so let's say out of all the options witch one will control dot gain the most? and I forgot to put... Sharpen your squeegee!  :-[

squeezee:
Dot gain is not a problem.  We can handle it with several of the means mentioned.  Variable dot gain (or any other variable) is a problem because if you are not sure what's going to come out, how can you compensate for it.

Sbrem:
If I had to pick one, durometer seems to be big in mind, triple durometer, 70/90/70, but really, all of them. Also, the wet white method, the one I learned was making a white printer that was the negative of the other 4 combined. We'd tape the 4 films together, cut a ruby mask around the outside, then create a negative from that stack, of all the white space between the dots of the 4 films. It worked pretty well, especially with the lower tensions of the day...

Artelf2xs:
you folks crack me up. Now an admin has added all the above.... My point is that one of the original mentioned is the most critical in controlling dot gain on press.
Not how to adjust films or screens for, or if it is a problem, or workaround solutions.

Which "ONE" element has the "MOST" impact on dot gain?
