.. 1 I. PURPOSE OF STUDY
The objective of this study is to determine the feasibility
of a continuous film-to-film contact printer that uses open-gate
techniques and has an output performance compatible with'current
state-of-the-art. Known factors contributing to degradation of
image quality in the system are to be analyzed.
Specific attention will be paid to the problems of assuring
film contact in the printer gate, as well as possible advantages
of using "liquid gate" techniques in the system. Also techniques
for film cleaning will be evaluated. The study will be summarized
in a test plan, which defines a program to evaluate experimentally
the most promising approaches.
II. ACTIVITY OF THIS REPORTING PERIOD
We have completed our evaluation of techniques and have pre-
pared a draft of the final report to be submitted on this program.
Liquid gate techniques and air bearing systems appear at the present
time to be the most promising methods for open gates.
Ultrasonic film cleaners appear to present the best overall
cleaning capability. Electrostatics may provide a good alternative
for cleaning.
III, PLANS FOR NEXT PERIOD
The final report and test plan will be submitted during
this period.
