1.0 CONTACT DUPLICATING AND RESEAU PRINTER
1.1 Purpose
The overall objective of the current contract is the design, fabrica-
tion, test and delivery of a Photographic, Step and Repeat, Contact
Duplicating and Reseau Printer. Prime design goals are high-speed
automatic operation, variable format capability, and high resolution
with minimum film distortion or damage. The delivered equipment
will be suitable for operational use. The printer will accommodate
films of 70 mm to 92" width with frame lengths up to 30 inches and
will provide operation in the reseau mode and selective mode as options.
1.2 Activity of this Report Period
Final acceptance tests at Army Map Service were interrupted by two
machine failures. The failure of the rider lift roller reported on
July 26 was traced to a burned out lift solenoid coil. A new coil

On August 8 there was a reported failure of the outer air bag. This
was discovered to be a tear along the front-left end of the outer
polyethylene bag. Repairs were made by
on August 10.
A trip was made-to Army Map Service on August 17 to review the test
results to date. The customer reported problems with punch alignment,
negative. advance accuracy, raw stock double exposure and uneven ex-
posure control. From review of the test data on the original transport
frame separation timer, it appears that the variations observed were
normal and the system is operating properly. Tests at

personnel visited Army Map Service on
August 24-26. The raw stock double exposure condition reported was
traced to a failure of the lift roller solenoid which was replaced.
?
The dodge circuit board calibration was checked, and two boards were
replaced. A film test did not reveal any gross adjustment diffi-
culties; however, a problem may exist when very weak negatives are
printed on fast film. The resultant exposure is extremely short and
is difficult to control with tungsten filament lamps. A remedial
solution may be the addition of a neutral density filter to increase
exposure time.
A new eyepiece and reticle were installed into the Pre View and Punch
?
Station, and the latter was recalibrated byl personnel.
Although alignment accuracy was improved, final calibration was not
achieved at this time.
1.3 Plans for Next Period
It is anticipated that acceptance tests will be completed.
1.4 Problems
The outstanding problem is calibration of the Pre View and Punch Station.
Methods for improving the precision are being investigated.
