We are interested in learning about the printing requirements on PWB's.
Specifically the variable printing that is currently printed on a board,
information we believe is known as "legend printing".  My understanding is
the "legend" printing indicates the components locations, part number,
company name or anything that needs to be printed.  I understand the
printing is a screen printing application and that there are some systems
developed by Pentax that prints on the board using an "ink jet" technology.

I would appreciate any assistance the members can provide as to:

manufacturers of the ink ( US AND WW )

types of ink available

volume of ink used

screen printing suppliers

current problems with the inks...is the resolution acceptable

what improvements are required

is the screen process expensive from a time point of view

are there problems with the time and expense to produce, clean and store
the screens

Would there be a market for a digital technology that would allow for a
rapid, direct printing technology that eliminates time, the storage of
screens and the screen cleaning process that provide high quality print.

I would appreciate any assistance to the above questions.  I would
appreciate the opportunity to speak to any of the respondents via the
telephone.  I look forward to the response.
