Title: Drying screens Level
Post by: Maxie on March 04, 2016, 12:29:32 PM

I noticed that the floor in my drying room is not level so my screens are not level while drying.
Does this matter?

are you seeing waterspots and/or high/low areas of emulsion thickness?

Hell, I even know of at least one veteran who dries them vertically and still manages to keep cranking out shirts, so, I doubt that a little out of level horizontal will queer the deal.

We dry them vertically. Have both cabinets, haven't been able to measure any ink thickness or EOM difference.

on some theoretical level yes, but I'm sure you're not noticing it...

we used to dry them vertically...worked fine.  we switched mainly because it takes up so much less space horizontally.

We made a cabinet long ago to dry our coated 18X21" Newmans and
when the auto came along just slid the 23X31" in on about an angle of 20˚
because of width being too narrow.

Never seen a difference with even that kind of angle. Not optimal, but I'd say
surface tension of emulsions viscosity is enough to over come any ill effect.

Hope your floor isn't that much off.  :o  :)

How about propping up rack to make level...

I cannot see any thickness problems, maybe I'll measure
We have a slight angle, the screens are on wagons with wheels so it's not easy to adjust the level.
I could take the wheels off and then level them if needed but looking at the answers I won't need too do that.

The higher the emulsion viscosity, the less you will notice if drying vertically.  Will only be noticed by high performers with a right-left or top-bottom variance in exposure parameters affecting highlights and shadows primarily.  MOST rag printers probably very minimally affected.

Graphic Guys who shapen squeegees ever 500-1000 strokes on 380+ mesh,  this is potentially a really big deal.

My 2 cents,
