the cost of the plate material should give any novice second thoughts about
diving into the hand washing of plates.
That said, I purchased a machine-washout platemaker after years of "trial
and error" and consistent success with hand-washout. The volume of work in
my shop convinced me because the commercial units are efficient and save
Although I was pleased with my results while hand-washing (and didn't expect
any improvement was possible), the results from the machine washout are
superior. This came as quite a surprise. With eighteen 40W bulbs I'm getting
much more even exposure than the eight 20W I used to use (now there are no
light corners or banding). The evenness of the brush pressure and repeatable
functions of the new platemaker mean sharper detail and noticeably crisper
Larger (and, needless to say, more expensive) plates are particularly
improved, because I don't need to submerge an 11x17 plate for fifteen
minutes of scrubbing with a 4x8 brush. Remember that the adhesive which
holds the polymer on the backing eventually dissolves in water--small
details are the first to go when washout times increase.
Hand-washing often works on medium to small-size plates, but a machine will
always do a superior job and can process the biggest plates just as well as
the smallest plates.
