Extremely interesting concept (wish I would have thought of that). I
got one dropped in my lap last week that may compliment this effort. As
I am sure you know Lithographic printing requires water/fountain
solution to accomplish the printing process, but there is also waterless
technology. These presses are extremely expensive, require different
plates and inks and are not so popular.

I got a call from one of the NIST funded MEC's who met this guy who has
developed an ink that does not need fountain solution, can be run on a
standard lithographic printing press with any type of plates and no
blanket/equipment changes. Cleans up BETTER with aqueous cleaners.
Sounds very interesting huh? I am going to visit this guy in January.
I want to see this for myself.

I would venture to guess he would be willing to try coated ink pans with
this ink if he had the opportunity. If you are interested in=
something like this let me know. You may be able to achieve your goal
much easier with this different ink formulation.

Deb,

I am writing to let you know of a project I am currently working on with
application to the printing industry. As a matter of fact, the project
has application over many industries, not just the printing industry.
What I am working on is a project to conduct a study of how non-stick
coatings can be used effectively in a printing operation. More
specifically, seeing how non-stick coatings applied to printing ink feed
pans reduce the need for cleaning solvents, labor investments in time
cleaning printing stations, press down time, and, of course, their
effect on the reduction of wasted ink and cleaning solvent emissions.

We know of 5 printers so far that have used NSCs to some extent on ink
pans with excellent results. However, they still needed to clean the
ink pans. My original objective (conceived in May 1995) was to identify
a non-stick coating that could stand up to the various types of printing
inks while virtually reducing the surface tension of the ink to zero
such that no cleaning would be necessary.

If interested, let me know if you want to talk about this further. We
already have funding from EPA to not only conduct this preliminary
study, but also to conduct a scale-up test in industry.
