Abstract
Abstract A method for reproducing color separation pictures on a recording material from original pictures, wherein each original picture is color-separated and color-corrected to obtain color separation picture signals of primary colors such as yellow, magenta, cyan and black, which are stored in a memory, and wherein according to the color separation picture signals read out of the memory each color separation picture is reproduced in one of recording sub-areas of each recording area which is divided into the sub-areas of the corresponding number to the original pictures.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A method for reproducing color separation pictures on a recording material from original pictures, wherein an original picture is color-separated and color-corrected to obtain color separation picture signals of primary colors, and then said color separation picture signals obtained are stored in a memory, and when color separation pictures of the original picture are reproduced in recording areas to which each of color inks is allocated corresponding to the primary colors or a reproducing material according to the other separation picture signals read out of said memory, characterized by comprising the following steps: dividing said recording areas into a number of recording sub-areas corresponding to the number of original pictures; allocating the original pictures to said sub-areas; and recording each of said color separation printing plates obtained by scanning each of said original pictures on said respective allocated sub-areas.
Claim 2
Independent Claim
139 words
A method for reproducing color separation pictures on a recording material from original pictures, wherein an original picture is color-separated and color-corrected to obtain color separation picture signals of primary colors, and then said color separation picture signals obtained are stored in a memory, and when color separation pictures of the original picture are reproduced in recording areas to which each of color inks is allocated corresponding to the primary colors or a reproducing material according to the other separation picture signals read out of said memory, characterized by comprising the following steps: dividing said recording areas into a number of recording sub-areas corresponding to the number of original pictures; allocating the original pictures to said sub-areas; and recording each of said color separation printing plates obtained by scanning each of said original pictures on said respective allocated sub-areas.
Claim 3
Dependent Claim
40 words
A method as claimed in claim 1, wherein each recording area is divided into said recording sub-areas of the corresponding number to the original pictures by detecting positions in directions of a recording cylinder's periphery and axis by detector means.
Claim 4
Dependent Claim
39 words
A method as claimed in claim 2, wherein said detector means in the direction of the periphery of the recording cylinder is a rotary encoder, and said detector means in the direction of the recording cylinder's axis is switches.
