An image data readout section (48) reads out image data on a color chart field corresponding to the calculated actual position. At the same time, image data on a white color field immediately above the color chart field is also read out.Type: GrantFiled: October 9, 2001Date of Patent: April 6, 2004Assignee: Dainippon Screen Mfg. Co., Ltd.Inventor: Tsuyoshi Okuda

Patent number: 6712000Abstract: A cylinder for a rotary printing press is supported by bearings that are situated outside of the spaced side frames of the press. Each bearing is arranged in a bearing bushing that is, in turn supported by the press lateral frame. All of the bearing is located away from the lateral frame.Type: GrantFiled: May 28, 2002Date of Patent: March 30, 2004Assignee: Koenig & Bauer AktiengesellschaftInventors: Helmut Holm, Kurt Johannes Weschenfelder, Thomas Gerhard

Publication number: 20040045469Abstract: A pearlescent honeycomb material and an apparatus and method for making expandable pearlescent honeycomb structures suitable for use as window coverings. In one embodiment, a pearlescent material is prepared and then folded into tubular strips. These folded tubular strips with adhesive lines applied to them are fed continuously through a cutter which cuts them into predetermined lengths. The cut strips are then accelerated to a stacker for further processing before the next cut strip arrives. In another embodiment, webs of material are fed continuously in a downstream direction, adhesive lines are applied, a middle web is slitted into strips, and the strips bonded along opposite edges to the outer webs. By choosing for the outer webs transparent or porous material, and for the middle web opaque material, a light or air controlling honeycomb structure results.Type: ApplicationFiled: March 21, 2003Publication date: March 11, 2004Inventors: Karen S. Herhold, Leo Warner

Patent number: 6698355Abstract: A patch measurement device which is capable of accurately detecting the position of a patch in a control strip is provided. In a patch measurement device 27, a data storage section 271 stores printed-image data containing a control strip printed on a printed material. A reference mark detection section 272 detects the positions of cross points P corresponding to reference marks rm contained in the printed-image data. An inter-mark distance calculation section 273 calculates a measured shortest distance with respect to the cross point P. An inter-mark distance correction section 274 calculates magnification correcting coefficients k, by utilizing theoretical shortest distances among the cross points P in deployed position information and the measured shortest distance. Based on the magnification correcting coefficients k and the values of pixels constituting the printed-image data, a patch position detection section 275 finalizes the patch position.Type: GrantFiled: March 26, 2003Date of Patent: March 2, 2004Assignee: Dainippon Screen Mfg. Co., Ltd.Inventor: Kazuki Fukui

Patent number: 6691610Abstract: There is disclosed a method for printing metallic inks wherein a fountain solution and a first imprint ink are concurrently deposited onto a printing plate. A foundation metallic ink is then deposited onto the first imprint ink followed by depositing a second imprint ink is then onto the metallic ink. One or more layers of process ink colors can then be deposited onto the second imprint ink. The fountain solution is adjusted to have a pH of from about 3.7 to about 3.9 and the metallic ink is provided to have a tack of from about 14 to about 16.Type: GrantFiled: November 1, 2002Date of Patent: February 17, 2004Inventor: Richad Wilen

Patent number: 6684773Abstract: A method of determining misalignment of color planes within an image forming apparatus. A first pattern is formed with a first color and comprises first and second sections. A second pattern is formed with a second color and positioned within the first and second sections of the first pattern. The alignment of the two color planes is determined by the difference in the amount of color within the first and second sections. The amount of misalignment may further be determined by the ratio of the difference in the amount of color within the sections and the sum of the amount of color within the sections. Perfect alignment of the two color planes results in equal color amounts in each section.Type: GrantFiled: March 21, 2002Date of Patent: February 3, 2004Assignee: Lexmark International, Inc.Inventor: Cary Patterson Ravitz

Patent number: RE41048Abstract: A combined lithographic/flexographic printing process having a plurality of successive printing stations for printing color images on a substrate in a continuous in-line process. One of the stations prints a first color image using the flexographic process and at least one of the successive printing stations prints a second color image over the first color image using an offset lithographic process in the continuous in-line process.Type: GrantFiled: May 20, 1999Date of Patent: December 22, 2009Assignee: Williamson Printing CorporationInventors: Bill L. Davis, Jesse S. Williamson
