2 KODAK VISION3 Color Negative Control Strips, Technical Data and Crossover Information

KODAK VISION3 Color Negative Control Strips 

Introduction 

KODAK VISION3 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 VISION3 Color Negative 

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

code 5012 for 16 mm, CAT 152 0444.

Important Improvements 


incorporate several important improvements into the control 

strips for Process ECN-2. 

• A VISION3 emulsion is being used for process control. 

The new format is exposed on KODAK VISION3 200T 

Color Negative Film 5213, while the former ECN control 

strip was exposed on KODAK VISION 200T Color 

Negative Film 5217. 

KODAK VISION3 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. 

KODAK VISION3 Color Negative Control Strips, Technical Data and Crossover Information 3

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 VISION2 200T Color Negative Film 5217, and 

the new format exposed on KODAK VISION3 200T Color 

Negative Film 5213. 

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 VISION3 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 VISION3 Color Negative Control Strips 

exposed on 5213 Film compared to the former VISION2 

Control Strips exposed on 5217 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 represented by 

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 possible solution problems. Most of the important 

photographic effects take place in the developer.

Control-Strip Crossover 

Important: During the inventory crossover from the old 

VISION2 Control Strips to the new VISION3 Control Strips, 

every effort should be taken in your operations to avoid 

switching back and forth. Your process control will be 

greatly simplified by depleting your supply of the VISION2 

Control Strips (except for what is needed for crossover 

purposes) prior to utilizing the VISION3 Control Strips. 

There will come a time when you will need to begin using 

a new batch of control strips. A new batch means a new code 

number, not a fresh box of strips with the same code number. 

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. 

When you first started using control strips, you had no 

previous reference and you set up your aim value parameters 

by reading the densities of the specified (D-min, LD, MD, 

HD, or D-max) control reference steps and applying the 

deviation numbers supplied with that batch. Using a new 

batch of strips is really no different, except you will have a 

new set of aim numbers, 

As the time approaches to change to a new batch (code), 

you will want to make a “crossover” from the current, or old 

batch. Crossover simply means to adapt to a change in aim 

numbers, not a change in processing technique. You should 

begin the crossover with at least a week’s supply of strips 

still available (never wait until you run out). 

The crossover to a new batch lets you get a “feel” for the 

new set of aim numbers. Do not attempt to match the new 

aim numbers to the old ones. If you do, you probably will 

find it necessary to change the mechanical and/or chemical 

specifications of the process, and this will most likely lead to 

a non-conforming unacceptable process. You will notice 

some differences in the way the new batch trends as 

compared to the previous batch. this is a normal batch-tobatch 

variation, and is to be expected. If you are unable to 

maintain a plot within your action limits with the new 

control-strip batch, call your Kodak representative to assist 

you. 

Use the following crossover procedure each time a new 

code number is put into service: 

Determine the aim values for the new batch, the same as 

you did for the current or old batch by reading the 

specified steps (D-min, LD, MD, and HD or D-max) of the 

reference strip and applying the correction factors. If there 

is more than one roll of the same batch, average the 

corresponding step densities for all reference strips in the 

batch, then apply the correction factors. 

Process an old and new control strip simultaneously at 

least three separate times. Do this at different times of the 

day, and better yet, on different days, until you have a 

number of pairs. During this time, continue to control the 

process with data from the old strips. 

Post the new aim values on the same form as the old, 

leaving an appropriate space between the two aim sets (as 

illustrated in Figure 14). This way you can see the 

differences of each control strip reaction at a glance. You 

will observe the tracking of the “old” batch as compared 

to the “new” batch, with each plotted to its individual set 

of aim numbers. Both should be tracking in similar 

directions, but not exactly. However, they still should be 

within the same action and control limits. Please 

remember, no matter how the aim densities differ in 

numerical value, you still use each set as your zero (0) 

reference line. 

Once you are comfortable with the new batch of control 

strips, use a new H-24F or Y-55 form to separate and not 

confuse the old and new aim numbers while making the 

daily notations. 

If, for some reason, there is a need to adjust the process to 

conform to the new batch of control strips to new action 

and control limits, cease processing and evaluate the 

entire system. Such a need for change indicates a 

fundamental system difficulty, which most likely involves 

all aspects of the process, not necessarily a problem with 

the new batch of control strips. If difficulty continues, 

contact your Kodak technical representative.
