A silver halide color photographic light-sensitive material for making a color proof and a method for making the color proof using the light-sensitive material. Halftone color proofs having a similar color tone of small dots and large dots can be obtained by the light-sensitive material and the method using it. The silver halide color photographic light-sensitive material comprises a yellow image forming light-sensitive layers, a magenta image foming light-sensitive layer and a cyan image forming light-sensitive layer which are different from each other in spectral sensitivity, and the magenta image forming layer contains a magenta coupler and an yellow coupler. The color proof is prepared by a method comprising steps of sequentially exposing the above-mentioned silver halide color photographic material to each of light having different spectral distribution through each of a plurality of black-and-white halftone images prepared by color separation of a color original, respectively, and developing the silver halide color photographic material with a color developer.

Silver halide color photographic light sensitive material for color

Significant improvement in color reproduction can be achieved by a direct positive silver halide color photographic material having at least one each of a blue-sensitive, green-sensitive and a red-sensitive direct positive silver halide emulsion layer, in which material at least one of said direct positive silver halide emulsion layer contains both silver chloride or a silver halide composed of silver chlorobromide or silver chloroiodobromide containing no less than 50 mol % of AgCl, and a specific compound that is capable of reacting with the oxidation product of a developing agent to release a specific compound capable of scavenging said oxidation product or a precursor of said scavenging compound.

Direct positive silver halide photographic material

A method of preparing a color proof from a silver halide color photographic light-sensitive material and a black-and-white halftone dot image is disclosed, wherein said light-sensitive material has on a support the photographic component layers including silver halide emulsion layers each having different spectral sensitivities, and one of said silver halide emulsion layers comprises a magenta coupler represented by Formula M-I; ##STR1## wherein Z represents a group of non-metal atoms necessary to form a nitrogen-containing heterocyclic ring including a substituted one; X represents one selected from the group consisting of a hydrogen atom and a group capable of splitting off upon a reaction with an oxidized product of a developer; and R represents one selected from the group consisting of a hydrogen atom and a substituent. The method comprises the steps of:

Method for developing a silver halide color photographic light-sensitive

A process for forming a color image is disclosed. In the process a photographic material which comprises a light-sensitive silver halide emulsion layer containing a 2,5-diacylaminophenol-based cyan coupler at a ratio of over 50 mol % of the total cyan coupler is processed with a color developer containing a color developing agent represented by Formula I at a ratio of over 55 mol % of total developing agent in the color developer, ##STR1## wherein R.sub.1 and R.sub.2 independently represent a substituted or unsubstituted alkyl group, and R.sub.1 and R.sub.2 may link together to form a ring.

Method of image formation using a silver ahlide color photographic

A method for making a color proof in a photo-mechanical process. The method comprises a step for exposing a silver halide color photographic light-sensitive material to light through a black-and-white halftone dot image, and a step for developing said silver halide color photographic light-sensitive material with a color developer. The photographic material is comprised of at least three silver halide emulsion layers which are different from each other in spectral sensitivity thereof, and at least one of these silver halide emulsion layers contains a specific yellow coupler and the color developer contains a specific color developing agent. A halftone color image having a color tone similar to that of image printed with printing inks can be obtained by the simplified process.
