KODAK VISION Color Print Control Strips, Process ECP-2D 3
Effects of Mechanical and Chemical
Variations
Figures 2 through 12 illustrate some of the photographic
effects of mechanical and chemical variations on KODAK
VISION Color Print Control Strips exposed on 2383 Film
compared to effects on batch codes 6101 (35 mm) and 6102
(16 mm) and above. Each plot shows the effect of a change
in a process variable (horizontal axis), on the dye density of
the processed film (vertical axis). These density plots are
deviated against the standard level for each variable (e.g.,
standard level for the variable is represented by a zero
density deviation).
The magnitude of the changes shown in these plots should
not be considered to be process control limits. Also, the data
presented are qualitative, not quantitative. The plots were
derived from experiments using small laboratory machines
in which all constituents were held constant except the
variable being studied. Hence, the figures should be used
only as trend charts and guides. If two or more process
variables are changed, the resulting photographic effect
illustrated may not be additive. Interactions can occur that
produce effects other than those predicted by addition. The
plots in this publication are representative only; they do not
contain all possible solution problems. Most of the important
photographic effects take place in the developer.
