2 KODAK VISION2 Color Negative Control Strips, Technical Data and Crossover Information

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.

KODAK VISION2 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 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.
