Publication number: 20150302286Abstract: Printing a screened image includes a computer for converting a contone image to a digital image. A digital front end provides a screening tile, a dither magnitude curve, a spot function for each of the cells in the screening tile and a displacement vector for each of the cells. The digital front end displaces the center of each cell spot function and constructs a halftone image from the contone image and the screening tile by comparing value of each pixel from the contone image to a corresponding threshold value from the screening tile. If the pixel value exceeds the threshold value set a corresponding pixel in the halftone image to one otherwise set the corresponding pixel in the halftone image to zero. An imaging system prints the halftone image on a substrate.Type: ApplicationFiled: April 16, 2014Publication date: October 22, 2015Inventor: Richard R. Bielak

Patent number: 8958129Abstract: A method of forming a screened image includes providing a contone image, a screening tile structure of M by N cells, a dither magnitude curve, a spot function for each of the cells in the screening tile, and a displacement vector for each of the cells in the screening tile. Threshold values for each of the cells are constructed by displacing the center of each cell spot function according to the displacement vectors and according to the dither curve. A halftone image is constructed from the contone image and the screening tile by comparing value of each pixel from the contone image to a corresponding threshold value from the screening tile. If the pixel value exceeds the threshold value set a corresponding pixel in the halftone image to one otherwise set the corresponding pixel in the halftone image to zero.Type: GrantFiled: April 16, 2014Date of Patent: February 17, 2015Assignee: Eastman Kodak CompanyInventor: Richard R.

Patent number: 8031911Abstract: A method for producing mottling in an image includes modifying digital colorant information in a digital image data file for at least one of a plurality of colorants. The degree of modification is based on digital colorant information in the digital image data file, mottling information from a mottling tile, and a colorant gain curve for at least one colorant. The colorant gain curve is obtained by determining a tint percentage, the variation of the tint of the printed at least one colorant when printed at a tint percentage on volume printing stock. The mottling information has a spatial frequency distribution substantially equal to the spatial frequency distribution of the mottling produced by at least one colorant on a volume printing stock. The method allows the digital image to emulate the image that would result if the digital image was printed on a volume printer on high volume printing stock.Type: GrantFiled: May 13, 2008Date of Patent: October 4, 2011Assignee: Eastman Kodak CompanyInventors: Andreas M. Albat, Richard R. Bielak

Publication number: 20080204771Abstract: A method for printing includes sending first image file data (160) and color target data (32) to a printing system (5) comprising a printer (7), a color measurement device and a controller (90). A first document (190) including a first image and at least one color patch (30) based on the first image file data and the color target data is sent to the printer. Measuring the color patch is measured to obtain an output color and a color difference between the output color and a goal output color is determined. A second image file data is sent to the controller. The second image file data is changed based on the color difference. A second document comprising a second image is printed, and a plurality of copies of a third document comprising the second image are printed.Type: ApplicationFiled: February 22, 2007Publication date: August 28, 2008Inventors: Andreas M.

Patent number: 5420722Abstract: A cylindrical microlens is mounted directly to a laser diode die by using reference edges touching the die at the emitting face and at the top face. Three edges are used to have a stable mounting. The cylindrical microlens, including the reference edges, is manufactured by drawing a glass preform, thus the edges are in perfect register with the optical center of the microlens.Type: GrantFiled: October 25, 1993Date of Patent: May 30, 1995Assignee: Creo Products Inc.Inventor: Richard R.
