Tim,
I am assuming you mean transparent base , If not what does the extender say
on the can? If it is indeed base, you would use it to make lithography and
etching ink more transparent. You will still get good color, but it will be
more of a trasparent color, so it will layer over itself, blue and yellow
making green instead of blue sitting on top of yellow and no green showing.
How much you use is trial and errorr. I just printed my print for #11 and I
used a lot of base and just a little color as I was after a very delicate
transparent look. But I usually use 1/2 base to 1/2 lithography ink. This is
Graphic Chemical's Handschy Lithography ink, other inks may not have as much
pigment and it may be too much base.
Let us know how it turns out for you....I bet you use that 5# can up in no
time, I use one every 6 months, at least.
Best to you,
Barbara
