Re: Cutting polymer plates



Last message of the day, I promise!!!  Man am I getting my
$10 worth.  

Susan, I cut the plates with the school's big honkin' cutter
thingie whatever it is called.  I tried scoring it with an
exacto, and bending back and forth, but always it would end
up being uneven and then my negative would sit unevenly on
the plate and leak light through.  They require a lot of cut
power!  Honestly, Susan, since I have to go into town to cut
the plates, I ended up just ganging a whole bunch of
different test things on one plate and using the whole plate
instead of cutting.  What is another 10 or 20 bucks when
you've already spend 700??? I'm kidding.

Now, speaking of plate tone--the funny thing is that I was
printing this one plate for a person in the collaborative
group.  He wanted the plate to look just like his original. 
I printed it three times for him--the second time I loved
it, with nice heavy plate tone.  He wanted the background
"white." So each to his own, I suppose.

The layer on the KM73s is much thinner than the layer on the
solarplates, and the solarplate surface is bumpier/more
textured, so I am surprised that you all think KM73s have
more plate tone?? But I'll accept your truth over Diane's...

Sorry to mix posts, but Jon, you said this: 

Too much exposure to the aquatint and you burn out
highlights, 
however.  Too little and the plate gets to be sticky and
mucky in the 
shadows.

Dan Welden says more aquatint exposure, the more the
highlights hold detail (I mean, up to a certain point
because overexposure in general results in a white plate). 
Do you find this not true?  Because I found that when I
increased my aquatint from 1mn15 to 5mn in the 10mn total
exposure I got more detail in my highlights.  

And what book is your friend Angela writing??

And as far as why I say "luck" with no mottling, I have
found that with UVBL whenever I assume mottling is gone, I
get some in the next plate.  But I have exposed 3 plates now
with powdering the positive and not the plate, with no
mottling.  The images were busy, tho. I still think is is
luck.  

If our tax refund is good, Amergraph here I come.  If it is
not, oh well.

When i get back to MT I will experiment with all kinds of
solarplate tests--sun exposure for one.  But also exposing
the screen last on top of the image.  

I'm hoping there will be some sort of booth on this stuff at
the SPE conference but maybe that is a CAA sort of thing. 

Keith, did you dig out from under the foot of snow you got
in Mpls??
