PRELIMINARY ACCEPTANCE TEST REPORT
Introduction: On July 5, 6, 7th, 1967, the preliminary
Acceptance Vests were performed on the Contact
Duplicating and Reseau Printer
The Test
25X1
Plan of September 22, 1966 was used as a guide.
Government personnel in attendance were
Tests Demonstrated:
1. Resolving Power. Using a Government furnished
target containing nine images of high contrast and
over 400 lpm, a number of prints were made at
locations selected by the program monitors. Nine
target positions were printed covering top, middle,
and bottom positions on the left, center, and right
of the platen. Exposures were made on SO-267 film
and processed in D-19 developer. Five readings were
taken of each target position. Out of a total of 44
separate targets and readings, 39 showed resolution
of over 300 lpm, with the remaining 5 readings showing
256 lpm or better. Overall average of 44 readings was
335 lpm.

2. Pre-View and Punch Station Alignment and Reseau
Operation. To demonstrate punching and alignment
accuracy, Reseau prints were positioned and punched
to simulate imagery with fiducials are frame edges.
Following the punching operation, the samples were'
then placed on the Reseau grid platen and printed.
On all four sample prints, the central Reseau
line was superimposed on the grid line near the top
of the platen. On two of the four prints, there was
about a two line width divergence of the black line
and clear line near the bottom of the platen. It was
also demonstrated that multiple prints could be made
of a punched Reseau print without change in grid
position. A number of additional sample punches
were made and measured on the microscope. Readings
were taken from slot-to-line and hole-to-line to
determine parallelity. Generally, the majority of
readings were within specifications.
3. Reseau Line Print-Out thru Various Densities.
Samples of Reseau Lines printed thru various densities
were displayed. A Reseau print was made thru four
Neutral Density filters ranging from 0.4 to 1.9. A
Reseau print was also made thru a typical aerial
negative encompassing a broad range of densities from

.05 to 2.2. Measurements of Reseau line width were
made on a microscope and averaged 15 microns in
width.
4. Raw Stock-Metering. To determine accuracy of Raw
Stock Metering, a series of 30 exposures'was..made of
a N. D. Filter on 70mm 228R film. An advance in-
crement of 312" was used for a 30" image... A 10ft.
section of film was processed and showed consistent
spacing with an error of * 1/16". The remainder of
the roll was given to the Government monitors for
processing. A second test was run using a13 2"
advance for a 12" frame. Approximately 20 exposures
were made and seven frames processed for measurement.
Spacing of frames was consistently 1 2" with a
deviation of ? 1/16". The remainder of the roll was
given to the Government monitors for processing.
Note: During the Raw.Stock Metering Tests, a Platen Latch
failure was noted. The front right platen latch was
not engaging properly and the inflation cycle could
not proceed. Temporary repairs were made to continue
the Test Plan.

5. Frame Edge Detection and Film Metering System.
With the ?lower drawer open. and a roll of processed
negatives in the gate, the Film Metering System and
Frame E~:_w Detection were satisfactorily demonstrated
on both positives and negatives with a variety of
frame legnths. Activation of the FDS photocells
was also demonstrated using clear leader.
6. Automatic Print Cycle. To demonstrate Film Metering,
Frame Edge Detection, Raw Stock Metering, and Auto-
matic Exposure Control in one combined test, a series
of 40-50 exposures was made of 70mm frames"of 10"
length. A section of approximately 10 ft. was cut
off and processed which showed satisfactory results
from all systems. The remainder was given to the
Government monitors for processing.
7. Film Damage. A separate test was not conducted for
film damage. However, the sample sections processed
during tests #4 and #6 were examined for scratches
and none were found.
8. Printing Rate. A separate test was not conducted
for print rate. Cycling rates will vary with film
speed and input density.

9. Interlocks and Controls. It was noted during testing
that controls, timers, and print selector were
functioning, and that interlock warning signals were
operational.
10. Film Fog Test. Due-to recent installation of a new
light seal on the lower drawer, the fog test was not
conducted. Previous tests run on the machine in Salem
and Washington proved satisfactory. Final tests will
be conducted after adjustment of the new light seal.
11. Mask Alignment. Mylar masks are being furnished to
the Government ready for cutting of desired frame
sizes.
MISCELLANEOUS
A number of print samples were displayed which showed
the improved latitude and capability of the revised
Automatic Exposure Control System. Typical aerial
negatives and a broad range of N. D. filters were
printed to show density compression and contrast en-
hancement. Whereas exposure control problems were
previously evident with images of 1.7 or greater density,
the latitude has now been increased to meet specifications.

Following completion of the Preliminary Acceptance
Tests, permanent repairs were made on the right
front platen latch. After 13,000 recorded cycles
on the Printer, i-L-- was found that the air cylinder
operating the platen latch.was contaminated and
binding. It was also found that the latching
mechanism had developed a mechanical interference.
Corrections have been made and the Printer is now
operational.

ADDENDUM
Film Fog Test
On July 12, 1967, after adjustment of the replacement
light seal on the lower drawer, a film fog test was per-
formed. A 30" section of 92" wide 228R film was placed
on the platen, the machine closed, and room lights turned
on for one minute. The section was then processed in
duPont 16D for 3 minutes. An unexposed film sample was
similarly processed. Densichron readings of both samples
showed 0.04 base fog with no measurable fog due to
exposure within the Printer. (Note: du Pont Handbook
indicates .05 base fog on 228R with 3 minute processing
in 16D.)

TEST PLAN
The following tests describe methods and procedures
to be used to determine conformance with the performance
requirements of the purchase description for. the Contact
Duplicating and Reseau'Printer and the Pre Vie:'and Punch
Station.
I. Resolving Power (Spec. Ref. 2.7 and 3.11)
Load the Printer with Type S0-267 duplicating film under
appropriate safe-light conditions. Insert over the
clear platen with emulsion side up, a 6" x 9" format of
six resolution targets of at least 400 lpm. With the
Exposure Factor Control set for an exposure value which
op optimizes resolution characteristics, and the duplicate
film advance set for a 30" advance, make onc?exposure
in each of five positions covering the length of the
platen in 6" increments and process under controlled
conditions. The lowest of the vertical and horizontal
readings shall be utilized, and an average of the
observers' readings recorded. Fifty per cent or more
of all readings shall be over 300 lpm. for acceptability.
2. Punch Station Alignment and Reseau System Operation
(Spec.?Ref. 3.4.2 and 3.4.3)
Utilizing special grid-line test films on stable-base
film, locate and punch the round and slotted holes in
each of the provided locations on the Pre View and Punch
Station. The resulting punching error shall be less
than + (+0.0002 inches) when measured from the center
of each perforation to the referenced grid line.
Each of the three test films will then be located on
cne printer, with the reseau grid in place, and printed
such that the output print ( on stable lease film, such
as 4427) will demonstrate. that the total error result-
ing from alignment, punching and placement in the printer
shall not exceed +.

Roseau Line Print-out (Ref. Spec. 3.4.2)
The Printer shall demonstrate capability for ex-
posing a Reseau Grid onto the duplicating film with
an output line width of 12 to 15 microns when pro-
jected through a native having a broad range of
densities, with a '_m thickness of approximately
7 mils. Line widt...re to be measured by microscope
or comparator at t.n discreet points.
4. Raw Stock Transport Test (Ref. Spec. 3.5 ar 3.6)
(Note: Film will be processed by Xerox)
A minimum of 2 - 250 ft. rolls of 70 mm film (5427
or 8430) and 92 inch wide film will be printed in
the printer in the automatic mode. Clear leader may
be used for input film, and the multiple print selec-
-or may be utilized. At least one roll shall be set
for 15-inch advance, and one roll for 30 inch advance.
The output processed film will show uniform frame
spacing and repeatability for all exposed frames.
5. Film Damage (Ref. Spec. 3.6)
Utilizing approximately ten feet of clean, unexposed
9'-2" wide film, mark off three areas at random of
approximately 9" x 9". Visually examine the selected
areas for scratches and delineate and record such
imperfections.
Load the film sample onto the negative transport of
the Printer with emulsion side up, and make a simulated
series of 30" long exposures in the Manual Mode (since
there are no frame-edges) with corresponding advance
of duplicating film. Upon reaching the end of the film
sample, remove the ten foot length and visually re-
examine the delineated areas to determine the extent of
any damage to the original film incurred during Printer
.operation. -
For the purpose of this test, an objectionable scratch
shall be defined as a single scratch or rupture of the
base or emulsion which extends for more than two feet
of film or a scratch which appears periodically at the
same point of every simulated frame for more than two
feet of film.
