Abstract
Abstract A method for preparation of the final film used for engraving a flat screen, belt screen or rotary screen for a printing machine. The final film is prepared from a photograph of the image to be reproduced and engraved by known techniques on a screen so as to provide a continuous repetitive pattern on the face of a pile fabric dyed in a continuous print dyeing process. Select areas of photographic images are montaged and put into a repeat pattern within a predetermined outline to establish the basic repeat. Four continuous tone color separations are made of the selected pattern to provide yellow, blue, red and black continuous tone negatives which represent the four colors of the original image. Each color separation is posterized and half toned to provide eight positive films. The films are selectively combined, blown up to the desired repeat size to provide a negative or positive which is used to prepare a flat bed screen or rotary screen for an otherwise conventional printing process.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A method for preparation of the final film used for engraving a screen for use in continuous print dyeing of textile fabrics with a continuous pattern wherein the image to be reproduced is taken from a photograph and provides a continuous pattern having a three dimensional appearance on the face of the printed fabric which comprises setting off a select area of the photograph to form a pattern with a predetermined outline to establish the basic repeat for the pattern without obvious discontinuities, preparing a plurality of continuous tone color separations of the selected pattern to provide red, green, blue and black continuous tone negatives which represent the colors of the original image, preparing a posterized and a half-tone positive of each color separation, selectively combining the posterized and half-tone positives to provide a negative for use in engraving one or more screens with the combined negative.
Claim 2
Independent Claim
147 words
A method for preparation of the final film used for engraving a screen for use in continuous print dyeing of textile fabrics with a continuous pattern wherein the image to be reproduced is taken from a photograph and provides a continuous pattern having a three dimensional appearance on the face of the printed fabric which comprises setting off a select area of the photograph to form a pattern with a predetermined outline to establish the basic repeat for the pattern without obvious discontinuities, preparing a plurality of continuous tone color separations of the selected pattern to provide red, green, blue and black continuous tone negatives which represent the colors of the original image, preparing a posterized and a half-tone positive of each color separation, selectively combining the posterized and half-tone positives to provide a negative for use in engraving one or more screens with the combined negative.
Claim 3
Dependent Claim
23 words
A method as set forth in claim 1 wherein the combined posterized and half-tone positive is blown up to a desired repeat size.
Claim 4
Dependent Claim
52 words
A method as set forth in claim 1 wherein said step of selectively combining includes combining one half-tone and one posterized positive to provide a negative for engraving at least one screen and selecting at least one other posterized half-tone positive to provide a negative for engraving at least one other screen.
Claim 5
Dependent Claim
42 words
A method as set forth in claim 1 wherein said step of selectively combining includes combining two or more half-tones and two or more posterized positives to provide two or more negatives for engraving two or more screens for the printing process.
Claim 6
Independent Claim
133 words
A method for preparation of the final film used for engraving a screen for use in continuous print dyeing of textile fabrics comprises setting off a selected area of a photographic image to be reproduced by the printing process, montaging the photograph to provide a pattern within a predetermined outline defined by the selected area to establish a basic repeat, preparing four continuous tone color separation negatives of the selected pattern to provide green, blue, red and black continuous tone negatives which represent the four colors of the original image, posterizing and half-toning each color separation to provide eight positive films, selectively combining the positive films and enlarging the selected positives to the desired repeat size to provide a negative of the enlarged positive used to engrave the screen for the printing process.
Claim 7
Independent Claim
133 words
A method for preparation of the final film used for engraving a screen for use in continuous print dyeing of textile fabrics comprises setting off a selected area of a photographic image to be reproduced by the printing process, montaging the photograph to provide a pattern within a predetermined outline defined by the selected area to establish a basic repeat, preparing four continuous tone color separation negatives of the selected pattern to provide green, blue, red and black continuous tone negatives which represent the four colors of the original image, posterizing and half-toning each color separation to provide eight positive films, selectively combining the positive films and enlarging the selected positives to the desired repeat size to provide a negative of the enlarged positive used to engrave the screen for the printing process.
Claim 8
Independent Claim
151 words
A method for preparation of the final film used for engraving a screen for use in continuous print dyeing of flat textile material with a continuous pattern wherein the image to be reproduced is taken from a photograph and provides a continuous pattern having a three dimensional appearance on the face of the material which comprises preparing a color photograph of said image, setting off a selected area of the photograph to form a pattern within a predetermined outline to establish the basic repeat for the pattern, preparing a plurality of continuous tone color separations of the selected pattern to provide red, green, blue and black continuous tone negatives which represent the colors of the original image, preparing a posterized and a half-tone positive of each color separation, selectively combining the posterized and half-tone positives to provide a positive for use in engraving one or more screens with the combined positives.
Claim 9
Independent Claim
151 words
A method for preparation of the final film used for engraving a screen for use in continuous print dyeing of flat textile material with a continuous pattern wherein the image to be reproduced is taken from a photograph and provides a continuous pattern having a three dimensional appearance on the face of the material which comprises preparing a color photograph of said image, setting off a selected area of the photograph to form a pattern within a predetermined outline to establish the basic repeat for the pattern, preparing a plurality of continuous tone color separations of the selected pattern to provide red, green, blue and black continuous tone negatives which represent the colors of the original image, preparing a posterized and a half-tone positive of each color separation, selectively combining the posterized and half-tone positives to provide a positive for use in engraving one or more screens with the combined positives.
Claim 10
Dependent Claim
38 words
A method for continuously print dyeing as set forth in claim 6 wherein the selected area of the photograph is montaged to balance out the image to provide natural continuity of the pattern forming the basic repeat .
