| 121 | Temporary support film for transferring white pigment layer | US850115 | 1997-05-01 | US5800962A | 1998-09-01 | Martin Benzing; Dieter Mohr; Juergen Mertes; Peter Blum |
| A process for the production of a color image is described, in which a photosensitive material that has a temporary support film, a colored photosensitive layer and an adhesion-promoting layer that can be activated by heat is laminated at high temperature and under pressure with an image-receiving material which carries, on a support, a pigment layer containing a white pigment. The photosensitive layer is exposed imagewise and developed to produce an image, the temporary support film is peeled off from the image-receiving material before or after exposure to light and, if required, these steps are repeated with at least one further photosensitive material whose colored layer has another color to produce a multi-colored image. The process gives color images having a smaller dot enlargement compared with a halftone original and is particularly suitable for the color testing of copy for multicolor printing. | ||||||

| (Objective) In a color-proof material performed by forming multi-color image on an arbitrary material (ultimate image-receiving material) such as paper using a photosensitive transfer sheet and an intermediate image-receiving sheet, the objective is to bring the quality close to the printed quality formed with inks alone.(Constitution) For the photosensitive sheet, the colored photosensitive layer is formed with a material comprising a synthetic resin emulsion with Tg=-20.degree. to 40.degree. C. such as acrylic ester or ethylene-vinyl acetate copolymer so that the image layer itself has heat-adhesivity. Moreover, the image-receiving layer of the intermediate image-receiving sheet is formed with a material containing a resin cross-linked copolymer of olefin and .alpha., .beta.-unsaturated carboxylic acid with metallic ions and a resin comprising a copolymer of ethylene and vinyl acetate in a proportion by weight of 100/0 to 10/90.(Effect) It becomes possible to transfer the image layer alone onto the ultimate image-receiving material, thus a color-proof close to the print formed with inks alone can be produced. | ||||||
| 139 | Hard copy imaging system | US746544 | 1991-08-19 | US5252425A | 1993-10-12 | Pranab Bagchi |
| This invention relates to a full-color hard copy imaging system and a process, where a multiply photosensitive donor sheet, comprising clear polymeric or an opaque paper base, coated sequentially with a first layer of patches of a cyan, a magenta, and a yellow dye, that are thermally diffusible, with a second layer also coated sequentially with patches of a red light sensitive, a green light sensitive or a blue light sensitive, negative or a positive working photoresist layer, in such a manner that each of the colored dye patches are in registry with their complementary color sensitive photoresist patches, is exposed with white light sequentially, three times in registry on the three primary light sensitive patches, through a multicolor image (a positive transparency or a photographic negative), to produce crosslinks, image wise, in the exposed areas in the case of the negative resist system, or to uncrosslink the resist structure image wise in the exposed areas for a positive working resist system. In the second step, the first color patch is laminated on to a receiver sheet that is composed of a clear plastic layer in which the chromogenic dyes are soluble, with or without a white reflective backing and the first color image is transferred to the receiver sheet by thermal evaporation. The image is formed due to the hindrance of diffusion of dye in the crosslinked regions of the resist layer in the donor sheet. In subsequent consecutive steps the two remaining color images are transferred, by similar thermal process in registry on to the receiver sheet, thereby forming a full-color image of the original image. | ||||||
| 140 | Pre-press proofing method | US728311 | 1991-07-08 | US5240810A | 1993-08-31 | Hamid Barjesteh |
| Most prepress color proofing systems require the use of special receptor sheets. The differences between the special sheets and the final print sheet can affect the desired color balance. The use of a proof image on a temporary transfer sheet, with an adhesive layer between the image and a final receptor layer, enables the use of essentially any printing stock or printing surface as the final proofing image substrate. | ||||||
