9.1 Introduction to processing
This chapter details the steps pre-programmed into the ATL-1500 for running specific processes. JOBO has made every reasonable effort to be sure that this information is accurate, however the various manufacturers can and do change their specifications for these processes. You should always confirm the processing procedure (and mixing instructions) by referencing the instructions packaged with the chemistry. Check for rotary-specific instructions.
Before processing valuable photo materials we strongly suggest that you become familiar and are satisfied with the quality of any process used!
The developer times listed are suggested starting points for proper processing. Due to a great many variables involved in any photo process, these times should only be considered approximately correct. For best results and personal preference, the development times may need to be adjusted. See section 4.7 for information on making adjustments.
Included with the information on the processes are bottle location numbers (from right to left). It is important to fill the proper chemical step into the properly numbered bottle for correct processing.
9.2 Processing process control strips
The use of the process control strips is not strictly necessary, however, their use is the best assurance of correct processing and is suggested for very critical commercial work.
Pre-exposed process control strips are available from Kodak and other manufacturers. Control strips can be processed in the AutoLab and compared against a strip pre-processed by the manufacturer. Variations between a control strip processed on the AutoLab, and the manufacturer's pre-processed strip will determine what adjustments (if any) need to be made to the process times or chemistry.
You must use a densitometer to make accurate evaluations of control strips. If readings are out of the chemistry manufacturer's specified range, refer to the chemistry manufacturer's process manual for corrective action(s). After adjustments are made, process another control strip.
Note 1: If you are unfamiliar with the use of a densitometer, see your local industrial photographic dealer.
Note 2: Process control strips are the most accurate system for ensuring that all the parts of the process are working to produce the expected final product. Judgment must be used, however, to ensure that the result is acceptable to the end-user. If you are processing for yourself, then you are the "judge and jury" of what is acceptable. When processing for others, having a process that is documented as standard or "in control" will alleviate potential problems with your customer and will help to determine what may have caused undesirable results in the customer's film. When the process is "in control", other non-processing related areas should be examined for possible cause.

Note 1: Kodak recommends diluting their E-6 reversal bath to 60% of the working solution (i.e. 1.6 gal. for use from 1 gal. of normal working strength chemistry) when using a rotary processor.
Note 2: Hand processing of E-6 films normally would require a 6:00 minute color developer time. JOBO tests have shown that decreasing the E-6 color developer time from 6:00 to 5:00 minutes produces the best results with the ATL-1500.
Note 3: The bleach needs to be aerated to work effectively. Unlike developers which are degraded by too much oxygen, the bleach needs to be fully oxygenated. This is accomplished by making sure that air is introduced while mixing the bleach. This can be accomplished several ways, for example, mixing in a larger container than the volume of bleach and stirring or shaking (while capped) vigorously. On a large scale, air can be bubbled through the bleach with a pump.
Note 4: Stabilizer should always be used outside of the processor to avoid contaminating tanks and reels. Use a separate container for stabilizing film and remove the film from the reel before stabilizing. Stabilizer is very difficult to remove entirely from reels and tanks. If it is carried over into the next process, developing can be affected.
Note 5: JOBO tests have shown that B/W film processing in a rotary processor such as the ATL-1500 is most even and consistent when a 5 minute pre-wet is used.
Note 6: See Section 9.4 for information on processing B/W film at times other than those automatically programmed in the ATL-1500.
9.4 Calculating development times for B/W film
In the ATL-2300/2400/2500, the development time for black and white film processing is automatically calculated based on the actual temperatures. With the ATL-1500 you must use the following chart to determine the correct development time based on what the chemical manufacturer states. The reason you have to do this is that the ATL-1500 processes B/W at 24.0ºC.
The chart below calculates the development time for the ATL-1500 assuming the chemical manufacturer states the development time at 20.0ºC (vertical value) is 12:00 minutes (horizontal value). To determine the correct time at 24.0ºC you first find the 24.0ºC/12:00min value ("A"), then trace the nearest bent line up the chart to the left until it intersects 24.0ºC (value "B"). Then, simply draw a line straight down until it intersects the minutes (value "C"). Based on this information, the correct development time is 9:30 at 24.0ºC.
