KODAK VISION Color Print Control Strips

Introduction

KODAK VISION Color Print Control Strips (Figure 1) are
intended for the control of Process ECP-2D using the
procedures described in KODAK Publication No. H-24,

Processing KODAK Motion Picture Films, Module 1,
Process Control.

The catalog numbers for KODAK VISION Color Print
Control Strips are CAT 156 1323 for 35 mm, and
CAT 820 8498 for 16 mm.

KODAK VISION Color Print Control Strips

KODAK VISION Color Print Control Strips, Process
ECP-2D, are packaged in 100-foot rolls containing at least
120 exposures and a processed reference strip. The
exposures on the roll are spaced at 9.5-inch intervals. Each
exposure has 21 gray-scale steps at 0.15 log H increments
(1/2 camera stop).

The reference strip accompanying each roll was exposed
along with all other control strips in the package; it was then
processed under specified well-controlled conditions. Keep

the reference strip at room temperature in its envelope to
help protect it from heat, light, and dirt.An instruction

sheet enclosed with the package contains process deviation
(correction) factors, if they are required, to determine your
laboratory process aim numbers. A four-digit code number
appearing on the carton, can, control strips, reference strips,
and instruction sheet, identifies each production batch of
strips.

Please be aware no two batches of control strips are
identical because of slight differences in product, exposures,
process, etc. And therefore, the aim value numbers will not
match (however, on rare occasions they could), even with
the application of the deviation factors. Beginning with

batch codes 6101 (35 mm) and 6102 (16 mm), you may
notice a shift in your aim values. IF you continue to be
satisfied with the way your images look, simply cross
over to the new aim values and continue processing as
you have.

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.
