It also includes the recommended cycles for processing

EKTACOLOR PRIME SP, EKTACOLOR PRIME, and 
EKTACOLOR RA Chemicals for Process RA-4.

For decades, Kodak has been designing and 

manufacturing films, papers, and chemicals that reduce the 
impact of photoprocessing on the environment. KODAK 
EKTACOLOR PRIME SP Developer Replenisher is a new 
developer for EKTACOLOR Papers that offers even more 
beneficial features. Formulated in a single part, it is 
convenient and easy to use. Intended for minilabs with 
average to high utilization, it will give consistent print 
quality with less effluent discharged and less packaging 
waste than KODAK EKTACOLOR PRIME Developer 
Replenisher. (See CHOOSING A PAPER PROCESS for 
more information on the availability and features of this new 
product.)

Although your choice of chemicals may be limited by 

your minilab’s design and its level of utilization, choosing 
the chemicals recommended in this publication ensures that 
you are using chemicals that provide optimum results with 
the smallest possible environmental impact. We continue to 
develop new products that will further reduce chemical use 
and discharge.

* Do not process films of older design that require a stabilizing agent for 

image stability in minilab processes using KODAK FLEXICOLOR Final 
Rinse and Replenisher. These films are KODAK VERICOLOR III Film, 
VERICOLOR Slide Film / SO-279/5072, and VERICOLOR Print 
Film 4111. Process these films only in a processor that uses 
FLEXICOLOR Stabilizer III and Replenisher. 

To determine which chemicals to use for your film process, 
locate the process cycle that best matches the sequence of 
processing steps and process times of your minilab.
The following section describes the three basic process 
cycles for films, and includes a listing of the appropriate 
KODAK FLEXICOLOR Chemicals for each cycle. You can
use any of these cycles with or without a wash step. If you 
select a washless cycle, carefully follow the 
recommendations in the footnotes.

Note: This publication does not discuss KODAK 
FLEXICOLOR SM and EKTACOLOR SM Chemicals, 
which are designed for use only in specific minilabs. For 
detailed information on these chemicals, see KODAK 
Publication No. Z-101, Using KODAK SM Chemicals in SM 
Minilabs.

Use the cycles in this publication as guides. You may 

have to modify a cycle slightly to suit the design of your 
processor. The replenishment rates for each cycle are 
intended for a typical mix of Kodak color negative films. 
For more detailed information, see KODAK Publication 
No. Z-100, Using KODAK Chemicals in Minilabs, or Z-131,
