| A light-sensitive color-proofing sheet is described for producing an image on various substrates. A light-sensitive continuous color layer is releasably attached to a carrier. Overlaying the color layer is a water-insoluble transparent colorless barrier layer. On the opposite surface of the barrier layer is a thermally laminable adhesive layer. Upon lamination of the sheet to a substrate, removal of the carrier and exposure to actinic radiation, the color layer is formed into an image, photomechanically, by removal of the non-image areas. | ||||||
| 163 | Method of forming a pressure sensitive image transfer sheet and the product thereof | US808524 | 1985-12-13 | US4640878A | 1987-02-03 | Robert Evans; Robert Evans, Jr. |
| There is described a photomechanical method for forming pressure sensitive transfer reproductions of color images, either single color or multicolor, upon a substrate involving the forming of a base coat protective layer on a substrate, applying one color ink layer on the base layer and a white ink overlayer on the one color ink layer. The surface of the white ink overlayer is powdered and a layer of photoresist composition is applied. The photoresist covered layered substrate is exposed to a light source through an image carrying photographic negative film to harden the photoresist at the imaged areas thereby forming a mask. Nonhardened photoresist composition areas along with their underlaying layers are removed using stepwise solvent development steps. The steps are repeated where different ink colors are to be applied to form a multicolored image. The final single color image or the final multicolor image, as the case may be, being thoroughly dried, finally coated with a pressure sensitive adhesive to form the image transfer sheet. Drying between each step of formation is essential. | ||||||
| 164 | Photosensitive material with two photosensitive layers for forming separate imaged elements | US532105 | 1983-09-14 | US4599295A | 1986-07-08 | Syuzi Kondo; Akira Yamano; Keiji Toei |
| Disclosed is a photosensitive material which has a first photosensitive layer formed on a support body such as an aluminum plate, a peel-off layer thereon and a second photosensitive layer formed on the peel-off layer in such a manner that the second layer can be photographically exposed to light and photographically developed independently from the first photosensitive layer and the first photosensitive layer may be subsequently photographically exposed with the picture image formed on the second photosensitive layer acting as a photographic mask. After the first photosensitive layer has been photographically developed, the two photosensitive layers may be used for different purposes, for instance, using the first photosensitive layer as a printing plate and the second photosensitive layer as a photographic film for making duplicate printing plates. Since the first photosensitive layer may be photographically exposed with uncontrolled light while the second photosensitive layer may be photographically exposed with a laser beam of small intensity, this photosensitive material is highly useful for use on a scanning image processing device. Also, a method of conveniently utilizing the photosensitive material is additionally disclosed. | ||||||

| The exposure latitude of positive-acting, color pre-press proofing photosensitive articles can be improved by positioning an optical filter between the separation half-tone positive and the photosensitive article. | ||||||
| 166 | Sulfur and/or amide-containing exposure accelerators for light-sensitive coatings with diazonium compounds | US359629 | 1982-03-18 | US4446218A | 1984-05-01 | Major S. Dhillon |
| This invention relates to proof film-type light sensitive diazonium materials containing accelerators selected from sulfur and/or amide-containing compounds which are capable of accelerating the contact exposure of negative-working diazonium compounds when such diazonium compounds are subjected to UV radiation. These accelerators enhance essentially photosensitivity speed. The invention also relates to presensitized reproduction materials comprising diazonium materials containing these accelerators. | ||||||
| 167 | Method of making hand proofs of color prints | US904135 | 1978-05-08 | US4258125A | 1981-03-24 | Ronald D. Edhlund |
| A table has a mechanically driven draw bar squeegee mounted thereon to spread ink and other substances in a uniform manner. There is an interchangeable plurality of such squeegees which may be sequentially placed in said table to enable successive layers of different types of materials to be spread, in sequence, over the surface of a paper. This succession of materials includes an isolation layer between successive colors of ink, whereby a mistake on work in progress does not necessarily lead to a final destruction of all previously done work. A feature of the invention is that the pigmented surface of dried ink is not seen through the tint of other material, such as photoresist, for example. Also, a releasable layer may be provided among the successive layers so that a hand proof copy may be transferred, as a decalcomania. | ||||||

| 170 | Wipe on color proofing process and product | US25684672 | 1972-05-25 | US3811882A | 1974-05-21 | HENRY V |
| A process of color proofing by a wipe on method and color proof product produced thereby wherein the color proof process comprises coating at least one side of a paper with a bichromate gelatin emulsion and thereafter drying the same; exposing the emulsion through a color separation negative so as to expose a portion of the gelatin and effect hardening of the exposed gelatin; applying a first desired color, i.e., pigment formulation, to the gelatin emulsion; washing the coated paper to remove the unhardened gelatin and thereafter drying the same; coating the paper again with the bichromate gelatin emulsion, drying the same and exposing this further emulsion through a second color separation negative so as to again cause the exposed gelatin to harden; applying a second desired color to the gelatin and drying the coated paper and finally washing the coated paper to remove the unhardened gelatin with subsequent drying. The steps of applying the bichromate gelatin emulsion, exposing the emulsion through a color separation negative, applying a desired color and washing the paper to remove unhardened gelatin can be repeated for as many colors as desired. One or both sides of the paper can be advantageously processed in the above manner to provide a color proof substantially indistinguishable from the actual copies made with subsequently produced printing plates. Additional variations of the above process are applicable including exposing the emulsion through more than one separation negative at a time with overprinting if desired.

| A colored image or pattern formed of one or more colored hydrophilic colloid layers is produced on a permanent support by transferring onto such support in the presence of an aqueous liquid from a temporary support carrying the same, an unhardened colored hydrophilic colloid layer containing a photosensitive iron (III) complex which yields iron (II) ions on exposure to active electromagnetic radiation, exposing the thus transferred colloid layer while in a substantially dry state to an image of such radiation, treating the exposed layer with an activator liquid containing a substance that releases iron (III) ions from the iron (III) complex, and washing away the exposed regions of the colloid layer leaving a relief pattern corresponding to the unexposed portion of such layer, these steps being repeated in sequence for each colored colloid layer transferred to the permanent support to constitute the ultimate colored image or pattern. A suitable activator liquid is an aqueous liquid having a pH above 8 and containing an alkaline compound selected from the group comprising an alkaline metal carbonate, ammonium hydroxide or a water-soluble organic base.

| THE INVENTION DESCRIBES A PROCESS FOR THE MANUFACTURE OF COLOURED HALFTONE AND LINE-WORK PHOTOGRAPHIC IMAGES E.G. FOR COLOUR PROOFING. AN ELEMENT COMPRISING A TEMPORARY SUPPORT AND A LIGHTSENSITIVE LAYER, WHEREIN A COLOUR PIGMENT IS DISPERSED IN A PHOTO-SOLUBILIZABLE BINDER MATERIAL, IS TREATED AS FOLLOWS:
(A) EXPOSURE TO LIGHT THROUGH A COLOUR SEPARATION TRANSPARENCY, (B) DISSOLUTION OF EXPOSED PORTIONS, (C) PRESSING THE POSITIVE IMAGE FORMED ON A RECEPTOR SURFACE WETTED WITH A SOLVENT OR SWELLING AGENT FOR THE PHOTOSOLUBILIZABLE BINDER MATERIAL AND SEPARATION OF THE TEMPORARY SUPPORT, (D) DISSOLUTION OF TRANSFERRED BINDER MATERIAL WHEREBY A POSITIVE PIGMENT IMAGE REMAINS ON THE RECEPTOR. IN THE CASE A MULTICOLOUR IMAGE IS DESIRED THE DIFFERENT STEPS ARE REPEATED WITH OTHER COLOUR SEPARATION TRANSPARENCIES AND OTHER PIGMENTED PHOTOSOLUBLIZABLE LAYERS ON TEMPORARY SUPPORTS, WHEREBY IN EACH STEP (C) THE NEW POSITIVE IMAGE IS TRANSFERRED TO THE RECEPTOR SURFACE IN REGISTER WITH THE PIGMENT IMAGE ALREADY PRESENT. WHEN THE TEMPORARY SUPPORTS ARE TRANSPARENT THE DIFFERENT COLOURED POSITIVE IMAGES FORMED ON THEM CAN ALSO BE COMBINED INTO REGISTER SO AS TO FORM AN OVERLY COLOUR IMAGE OF THE ORIGINAL. |
