"He who marches out of step hears another drum." ~ Ken Kesey
Mark...... I'm pleased you mentioned blade sharpness. Quite often one of the most overlooked interdependant variables. I know of many flatbed printers that dispose of the squeegee material when finished with the run and simply replace it just for the secure knowledge that it is a stable variable. Correct me if I'm wrong; I know of no tool to measure this.
Pierre (bluemoon) mentioned this somewhere else and I've been intrigued by the idea ever since but haven't tried it yet. If it is the case that 330/30 might allow a printable dot a couple percentage points lower (or higher) how much differnce could it make visably on a print? I'd love to hear Pierre's take on this as well.TIA
This is a very, very common question and there's usually some "machoism" associated with it. You know, I can print 85 lpi all day, and so on. Here are some things to consider. Just because you can print a finer dot, doesn't mean you should.
Add 2% - 5% high density base to you colors and you will dramatically improve (reduce) the dot gain in the midtones and significantly open up the shadow detail.
