KODAK VISION2 Color Negative Control Strips

Introduction

KODAK VISION2 Color Negative Control Strips (Figure 1)

are intended for the control of Process ECN-2 using the

procedures described in KODAK Publication No. H-24,

Manual for Processing KODAK Motion Picture Films,

Module 1, Process Control.

The first batch of KODAK VISION2 Color Negative

Control Strips is code 5011 for 35 mm, CAT 152 0469 and

code 5012 for 16 mm, CAT 152 0444.

Important Improvements

KODAK VISION2 Color Negative Control Strips

incorporate several important improvements into the control

strips for Process ECN-2.

• A VISION2 emulsion is being used for process control.

The new format is exposed on KODAK VISION2 200T

Color Negative Film 5217, while the former ECN control

strip was exposed on KODAK VISION 200T Color

Negative Film 5274.

KODAK VISION2 Color Negative Control Strips,

Process ECN-2, 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 0.20 log H increments

(2/3 camera stop).

The reference strip accompanying each roll was exposed

along with all other control strips; it was then processed

under specified well-controlled conditions. 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.

Control Strip Log Exposure Range

The graphs in Figure 2 and Figure 3 demonstrate the

differences between the former ECN control strip exposed

on KODAK VISION 200T Color Negative Film 5274, and

the new format exposed on KODAK VISION2 200T Color

Negative Film 5217.

Physically, the center-to-center step distance has been

maintained on the new control strips; no problems should be

encountered with existing automatic densitometers.

Once the transition to the new control strips is complete,

and the new control step reference values have been

determined, continue to use KODAK VISION2 Color

Negative Control Strips in the same manner as your previous

control strips.

Please contact your Kodak representative for additional

information on monitoring your process with control strips.

Effects of Mechanical and Chemical

Variations

Figures 4 through 13 illustrate some of the major

photographic effects of mechanical and chemical variations

on KODAK VISION2 Color Negative Control Strips

exposed on 5217 Film compared to the former VISION

Control Strips exposed on 5274 Film. 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 representedby

zero density).

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

variable 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 possiblesolution problems.Most ofthe important

photographic effects take place in the developer.
