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: 6
Claim 1
Independent Claim
152 words
A method for continuously print dyeing 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 fabric which comprises 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 half-tone positive of each color separation, combining the posterized and half-tone positives to provide a negative, engraving one or more screens with the combined negative, passing the fabric to be dyed under the engraved screens and selectively applying dye stuff through the screens to reproduce the pattern on the face of the fabric.
Claim 2
Independent Claim
152 words
A method for continuously print dyeing 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 fabric which comprises 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 half-tone positive of each color separation, combining the posterized and half-tone positives to provide a negative, engraving one or more screens with the combined negative, passing the fabric to be dyed under the engraved screens and selectively applying dye stuff through the screens to reproduce the pattern on the face of the fabric.
Claim 3
Dependent Claim
21 words
A method as set forth in claim 1 wherein the fabric is carpet and the face is an upstanding pile yarn.
Claim 4
Independent Claim
155 words
A method for continuously print dyeing flat dyeable 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 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, combining the posterized and half-tone positive to provide a positive, engraving one or more screens with the combined positives, passing the material to be dyed under the engraved screens and selectively applying dye stuff through the screens to reproduce the pattern on the face of the material.
Claim 5
Independent Claim
155 words
A method for continuously print dyeing flat dyeable 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 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, combining the posterized and half-tone positive to provide a positive, engraving one or more screens with the combined positives, passing the material to be dyed under the engraved screens and selectively applying dye stuff through the screens to reproduce the pattern on the face of the material.
