Embodiment 1

[0035] This is an embodiment of the present invention.

[0036] Table 1 compares two processing cycles, one of which has a one-step solution development phase and the other a two-step solution process. All remaining stages of the cycle are identical and are standard C-41 methods.

[0037] Table 1 Two-step development method and one-step development method

[0038] Treatment 1 Treatment 2

[0039] Phase Part 1 Part 2 One step

[0040] Develop 5 seconds 25 seconds 30 seconds

[0041] Stop display for 30 seconds - 30 seconds

[0042] Bleach 3 minutes 30 seconds - 3 minutes 30 seconds

[0043] Fixing 3 minutes 30 seconds - 3 minutes 30 seconds

[0044] Wash 2 minutes - 2 minutes

[0045] Wherein the bleach solution is Kodak Flexicolor Bleach Solution III NR, the fixer is Kodak Flexicolor fixer, and the supplement and stop solution are 10% acetic acid. Shown in Table 2 are the compositions of the one-step solution and the compositions of th...

Abstract

A method of processing photographic material in which a fixed volume of processing solution is added to the surface of the material and spread repeatedly over the length of material. The processing solution is added to the material in at least two stages.

Description

technical field [0001] This invention relates to methods and apparatus for processing photographic elements. In particular, the present invention relates to a treatment method using a small amount of treatment liquid. Background technique [0002] Traditional photographic material processing requires the use of large tanks containing separate processing fluids. Each tank contains a processing solution such as developer, bleach, fixer or cleaning solution. The material passes through each slot sequentially. The solution is easily carried from one tank to another, contaminating the solution. Traditional processing also has some other disadvantages. The temperature that can be used is limited, so the 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. [0003] To overcome these problems of...
