  • Patent number: 5751829
    Abstract: A system for selecting decorative materials is based on large numbers of high-resolution, full color images of decorative materials stored in a compressed format on an inexpensive medium such as a CD-ROM. In creating the ROM, each image is coordinated with additional information such as style of pattern, type of material, and other auxiliary information. Before final compression and storage of the image data color information is added by spectrophotometrically analyzing the decorative material. Color values for a background color and up to four foreground colors are determined. Individual colors are then referenced to a comprehensive color standard system containing a large number of standardized color swatches. Spectrophotometric color referencing allows the data records to be rapidly searched on the basis of color, as well as the other information in the record. Wallpaper patterns, drapery material, floor covering, or paint can then be rapidly selected on the basis of matching color.

  • Patent number: 4980262
    Abstract: A photographic contact printing process is disclosed having application in the mass production of replicate video discs from a master disc, and other applications wherein it is desired to replicate micro-detail over a relatively large area. A problem with conventional contact printing from a mask to a photographic medium is one of maintaining intimate contact over a relatively large area since dust, dirt, etc., are almost impossible to completely eliminate in any practical manner. In accordance with the present invention, a contact printing process is provided wherein intimate contact is not necessary for making high quality contact prints. The present invention recognizes that in contact printing information from a master disc to a replicate disc, the contact printing process is significantly less sensitive to imperfect contact between the master disc and the replicate disc if one employs a replicate disc comprising a photosensitive material having a certain optical properties.

  • Patent number: 4159176
    Abstract: There is described an exposure frame for aligning and holding photomasks in registration with a printed circuit board coated with a light sensitive material. The printed circuit board is held between an independently adjustable mounting strip and slides. A contact strip is floated on the mounting strip by a spring mounting to permit the slides to position the printed circuit board relative to the photomask. The photomask, in turn, is mounted on the adjustable mounting strip. This facilitates good registration between the board and mask.
