DESCRIPTION OF EQUIPMENT
SPAN ENLARGER-PRINTER-PROCESSOR
MODEL EPP9 - 500
(Reference Drawing 606601L1)
DECLASS REVIEW by NIMA/DOD
The purpose of this equipment is to produce high quality, duplicate
positive transparencies or positive prints in any required quantities,
from selected 70 m/m, 5 inch or 92 positive transparencies. The out-
put of the equipment is 9/ inch projection printed reproduction, re-
sulting from a 4:1 enlargement of a 70 m/m transparency, a 2:1 en-
largement of a 2:1 transparency and a 1:1 enlargement of a 92 inch
transparency. The processing techniques used in this equipment is
the SPAN process (Simultaneous Positive and Negative), which also
produces an intermediary fully developed negative. The processing
media is contained in the Bimat material which ultimately
becomes the reproduction. The equipment includes as an accessory, a
Bimat Preparation Tank, Model #BP9-500, for imbibing the Bimat material
with the processing solution.
DESCRIPTION
The equipment is a ground based console, suitable for installation
in military photo-processing or photo-interpretation shelters. it
STATINTL utilizes a light table complete with microscope and
film rewinds. The light table which contains a vacuum platen for
maintaining film flatness is mounted on chassis slides for ready
insertion into the optical path for printing. Other major components
of the equipment are:
1. Quick change lens mounting
2. 9/" x 500 foot negative supply spool
3. Vacuum platen
4. Slack box
5. Bimat Supply spool
6. Processing Drum

8. Dryer
9. Positive Takeup
OPERATION:
The operation of the equipment is semi-automatic. Bimat material
which has been properly saturated in the Bimat Preparation Tank, is
threaded through the EPP9-500 together with the negative material,
as indicated in the drawing. Intimate contact between the two is
maintained on the processing drum. The drum is heated to the proper
processing temperature level.
Exposure of the negative and frame advance is accomplished by
actuation of a push button switch on the control panel. The negative,
is exposed, advanced and stored in the slack box until a quantity has
been accumulated. Several additional frames are then added for leader.
The processing switch is then actuated and the negative is transported
at a continuous speed of 12 inches per minute over the processing
drum together with the Bimat material. During this transport period,
the chemicals in the saturated Bimat process the negative to completion
and simultaneously transfer a positive image to the Bimat. The
negative material is then wound up on a takeup spool while the Bimat
continues through a drying stage to its takeup spool where it may
be removed for immediate viewing.
