LESSON 1
(2) Although it can be handled under the Wratten OC safelight, its
sensitivity limits its exposure to the safelight to no longer than 3
minutes.
c. Processing methods.
Ektamatic SC paper may be processed by
conventional paper processing methods using a standard developer and fixer
solution.
However, the advantage of rapid processing necessitates use of
special chemistry with this paper.
Only two solutions are required to
produce a visible, semipermanent image on the conventionally exposed paper.
(1) An activator solution, A-10, reacts with the developer-
impregnated paper to convert the latent image into a visible image. A short
stop or rinse bath is not required before stabilization.
(2) The stabilizer solution, S-30, neutralizes further effects of
development and greatly reduces the emulsion's sensitivity to light. Note
that the light sensitivity has been reduced, but not completely neutralized.
The resulting degree of permanency of stabilized prints, therefore, depends
on the extent of their exposure to heat, light, and humidity.
Since
stabilization-processed prints are normally produced for short life
requirements such as proofs or for immediate reproduction by news media,
their lack of permanence poses no problems.
(a) To achieve lasting permanence of Ektamatic SC paper, it must
be fixed, washed, and dried by conventional methods.
(b) Procedures for obtaining permanent images are explained in the
data sheet supplied with each package of paper.
d. Stabilization processing equipment such as the Ektamatic 214K
squeegees the prints through rollers after they have passed through the
stabilizer solution.
The paper then is in a damp-dry condition with a
semigloss finish.
Complete drying occurs within a very few minutes at
normal room temperatures.
A glossy finish is possible only after drying
with normal print drying equipment.
Since this drying method normally
requires heat, the print must first be fixed in conventional fixer then
washed to prevent image deterioration.
2. Installing the model 214K Kodak Ektamatic Processor.
The Ektamatic
processor was designed to process exposed stabilization photographic paper.
Sizes range up to 14 inches in width and 6 feet long.
Two solutions
(activator and stabilizer) are supplied in plastic bottles and no chemical
mixing is necessary. The processor should be positioned
