Super Wide Print Straightener
1. Introduction:
Photographic papers are emulsion coated on one side only;
this results in differential drying of the two sides of the paper
causing contraction of the emulsion and a decided curl toward the
emulsion side.
Although commercial print straighteners will not accommodate
prints larger than 14" in width, there does not appear to be any
technical reason to prevent their being made to accommodate larger
print sizes.
2. Concept:
Briefing prints are frequently made in sizes up to 40 inches
in width. It is intended that this print straightener will be used
to remove the curl from paper prints, thus permitting their use
without the necessity of mounting. It is further intended that the
equipment be of such weight and size that it may be readily moved
from one location to another. It is assumed the design of the
equipment will require electricity for its operation and will make
use of liquids for generation of moisture or vapor. Any solution
used must be non-injurious to the emulsion.

3. Scope:
This project is for the development, design, fabrication, test
and evaluation of a, prototype model of a. print straightener to accept
paper prints up to 40 inches in width. Literature requirements
will include a, final report on the development and such speqification
and drawings as may be required to permit subsequent procurement
of the equipment.
4. Philosophy:
There are several methods presently being used to accomplish
this purpose; one is to stretch the emulsion by passing the print
over a. series of rollers with the paper base next to the roller.
This method sometimes damages the emulsion. The more acceptable
method makes use of a combination of rollers and the application
of moisture. The moisture technique is acceptable, however, any
method may be used so long as it meets other requirements stated
herein and does not damage the print or the emulsion, or have any
adverse effects on dry mounting.
5. Requirements:
Physical - the print straightener shall consist of a feed table,
belts, or rollers as may be necessary to transport the prints through
the equipment and a basket or container to receive the finished
prints. If water moisture or other vapor is required the equipment

shall include a removable tank to contain the liquid, a flexible
line input and automatically controlled solution level in the tank.
If heat is required for the generation of moisture or vapor,
electric heating elements shall be contained in the body of the
tank or shall be a securely attached inversion type heater. Either
method shall include thermostatic control.
This print straightener shall be capable of accepting either
single or double weight black and white paper prints of the
commercial variety (such as Kodabromide, enlarging; or AZO, contact;)
in any width from 70mm to 40 inches at continuously variable speeds
up to 60 running feet per minute. The equipment shall be as light
and compact as is consistant with other requirements. The equip-
ment shall not exceed 50 inches in width or 80 inches in length,
including the feed platform and the take up receptacle. The
equipment is intended to be table mounted. However, if the total
weight exceeds 100 pounds it shall be provided with stand and
casters.
Electrical - The equipment shall be designed to operate on
110-120 volt 60 cycle single phase AC, with a maximum power load
not to exceed 15 amps.
