6. RFI was discussed briefly and it was confirmed that design and fabrication
to specificationslwould be sufficient without RFI test procedure.
7. Pre-View and Punch Station. Basic philosophy is to relegate precise
fiducial locationland alignment to off-line station. At the Printer, frame
location should be quick, easy, and dark-room operable. No optical devices or
tedious adjustment at Printer is desired. This rules out optical alignment at
Printer and emphasizes quick manual location of punched holes over pins. Morton
states that wear on punched holes is not a problem since frames will not be
used more than 2-4 times. The problem of possible parallax and simultaneous
focus of fiduciall and single grid-line was mentioned since they lie in different
plane . i~l~lilco.ncentrate on,or,iginal punched-hole , and, raised-pin alignment.

Negative film may be advanced and viewed in semi-auto. mode with pull-out
drawer extended, interlock will prevent advance when pins are extended.
9. Masking.' Best location for mask appears to be under platen so as not
to add thickness between films or under films. Masking in length is of primary

Presentation of latest approach to exposure control was made by
Multiple light source (120 G. E. 1385 bulbs) was proposed with
according to amount of light transmitted to photocell through negative frame
(and through platen, dupe. film, and air-bag)
Collimation of light sources will be controlled so as not to. distort Reseau
lines or overlap into areas which have already received sufficient exposure.
However, some diffusion is desirable so as not to effect a pattern of lights
on dupe. film. System delivers gross dodging in lateral as well as longitudinal
direction of frame.
1:1 ratio of controlling photocells. Each lamp would be programmed in time
Monitors received system well, and approved of configuration and intent. Pre-
liminary demonstration of system to be held on October 20th at
Circuitry may not be complete by then, but is being breadboarded at present.

MINUTES OF MEETING
HIGH RESOLUTION STEP & REPEAT PRINTER

U. S. Government
1. Presentation of Artist's Concept" Materials
Technical monitor feels that material is satisfactory for the present, but
would like to see 20" x 24" mattes with more color for a future presentation
in about six weeks. Polaroid color snaps were given to the monitor for the
present.
2. Technical monitor suggested that we consider future possibilities of com-
bined features of printers I and 2 since the basic features are similar.
3. Control Panel
Preliminary configuration and modes of operation were discussed. Monitor
requested. resets for all pushbuttons one at a time, or a self cancelling
feature.
"Emergency Stop" philosophy was questioned. It was pointed out that in the
event of a malfunction, the machine could not be restarted until it was
cleared.
4. RFI and Power Distribution
Monitor re-emphasized 208 volt, 4 wire, 3 0 power, with no D. C. available.
It was re-affirmed that equipment would comply with RFI spec but that tenta-
tively no testing would be required.
5. Film Coding
Seventeen approaches to film coding were listed, and the monitor eliminated 14.
Remaining options are marking inks, fluorescent penetrants, and ultrasonic
deformation.
The coding size was tentatively determined to be approximately 3/32" x 1 with
13 code bits.

6. Film Gate
Monitor emphasized that #8430 will be the primary duplicating material.
Newton rings or granular methods for correction cannot be tolerated.
7. Film Handling
Loop systems were discussed as a means for providing minimum film motion.
Monitor suggested that 0 successfully used vacuum capstans, but that
had problems with dimpling in their wet processors. A
multiple roller guiding system was mentioned as existing in an enlarging
printer at the monitor's facility.
8. Exposure Control & Dodging
A presentation was made by on the parameter study. Monitor states
that film processing would be controlled from roll to roll but that constant
gamma could not be guaranteed.
Statistics on gamma, density ranges, D maximum, D minimum, etc., will be
provided by the monitor later in the program. It was generally felt by
the monitor that maximum contrast expansion of low contrast negatives is
desired even though the results may not be pleasing from an aesthetic point
of view.
Monitor suggests that he will bring experts from his facility to at a STAT
later date to specifically discuss sensitometry, photo interpretation, exposure
control, and dodging.
A presentation was made by 0 on a possible approach to exposure control.
It was generally agreed that the approach was a good one, but was neither
accepted nor rejected by the monitor as meeting all of the technical require-
ments.
9. Agreements
There were no new agreements made at the meeting.
