Roland,
Sounds like we both go back a bit in the industry. We used to do
red-blue separations and pad masters. Everything was shot on a Brown
3000 horizontal camera. I bought my first photoplotter in 1987 and
sold the Brown camera. Kept a smaller Eskofot vertical camera that I
still have and use on occasion. Most of the time I use a table top
Lavenir photoplotter. Also have a Gerber Crescent 30 photoplotter in
storage but haven't used it in several years. I bought the Lavenir
plotter in 1989 and it's never failed yet. That machine just keeps on
running. It may become obsolete along with the cameras when rapid
access film is no longer available. I still have some rubylith film
and use it once in a while!
