C41 Process Chemistry for Laboratories with Low Throughput
Applies to : All C41 processors only achieving low film throughput - all minilabs and other processors
Introduction
In recent years film volumes have declined dramatically, and many (perhaps even most) minilabs (in particular) are processing less that 10 films per day - or even less than 5 films per day, yet wish to continue to operate their film processors. Professional labs now generally have C41 processors that are far too large for their current film volumes. The result is a decrease in process quality - decreased contrast and increased DMin (base stain) on the film. This gives poor print quality, even with the boost given by digital printers such as the Fuji Frontier. The less films you process, the worse it gets. Just allowing the film process to get worse and worse will simply mean that customers will no longer bring you their films, and film volumes will decrease even further.
Until now, the only workable solution has been to dump the developer working tank - and sometimes the replenisher (and other baths) as well - and replace with fresh solution. Now there are chemicals available to greatly reduce low throughput problems - EnviroNeg Developer 60 AC for most minilabs and professional processors (or even large finisher machines), and Fuji CN-16SER for all Fuji CN-16S process film processors. Under all but the most extreme low throughput conditions, proper use of these new chemistries from FUJIFILM will avoid any requirement for developer retanking - previously necessary to retain process activity.
EnviroNeg Developer 60 AC for Minilabs, Finishers and Professional Laboratories
Further information on Fuji Hunt EnviroNeg Developer 60AC for general use in most types of film processor can be found by clicking here. There is also a new bleach - EnviroNeg RA Bleach 10 AC - available that compliments the quality gains offered by EnviroNeg Developer 60 AC, and suitable for use on all C41RA process film processors.
