Re: more and more and more solarplate

I think I guesstimated once it was something like 240-300 dpi.  Had a client say recently that even under a lupe the dots in the prints from the plate I made for him with the 1800 dpi screen were essentially invisible.  Granted that particular print had a bit of plate tone...but it was quite the compliment nonetheless. 

More soon...

Jon... I'm using the same screen as Keith (Dan Weldon's).  I'm getting basically the same exposure times as you, adjusted for my 1000w Nuarc.( about 44 sec each exposure)  I wish I knew what resolution this screen is... I keep trying to count dots, but then I blink and well....

The exposure times are very close to what Jon suggests, 10-11secs for
a 5K lightsource. This is much less than I would have usually have
exposed the plate for (45secs). From the very quick test I ran, there
is definitely a deeper black although the midtones don't seem to have
shifted at all. With such a short exposure/washout, I was worried
that it might be uneven but it's actually very uniform, even in a
smooth grey sky.

I have never liked deep blacks or stark whites in my work, preferring
some tone in the highlights, and detail that you have to look for in
the shadows; the km73s give you that plate tone in the highlights.
But with Jon's method I may have to be careful, for the blacks are so

As I mentioned before, I've played with numerous combinations of
screen and image exposures and every time, the best was always 50:50
(+or- 10%).

What effect did you notice with shorter washout?

Longley exposes the positive on KM73 for about 3 minutes ( 2.5 in
summer sun) and then the aquatint on top for 1 minute.  I find that
an interesting combo of times...
