Description

technical field

[0001] This invention relates to methods and apparatus for processing photographic material. In particular, the invention relates to a method of charging a treatment liquid into a treatment machine. Background technique

[0002] Traditional photographic material processing requires the use of large tanks that are individually filled with processing fluids. Each tank contains a processing solution such as developer, bleach, fixer or cleaning solution. The photographic material passes sequentially through the slots. The solution is easily carried from one tank to another, contaminating the solution. Traditional processing methods also have some other disadvantages. The temperature at which it can be used is limited, so processing is slow. The composition of the solution must remain stable over time in the treatment tank. Solution replenishment is also difficult to control. Since there are many processing tanks, the processing equipment is very large. ...
