Gray Scale Calibration Tool For Setting The Density Of A Printer

View page
US Patent:
6804027, Oct 12, 2004
Filed:
Jul 30, 2001
Appl. No.:
09/918260
Inventors:
Ho Chong Lee - Endicott NY
Larry David Teklits - Loveland CO
Jack Louis Zable - Niwot CO
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B41B 508
US Classification:
358 19, 358401, 358406, 358504
Abstract:
Density calibration for a printer is achieved using a standard grey scale vignette master and a stored gray scale vignette image that the printer operator can invoke from the operator panel of a printer. The vignette image provides a precalibrated scale that is used in conjunction with the âstandardâ image to determine the proper optical density. The density is then set by the printer control panel based upon the value obtained by visually matching the two grey scale vignettes.

Non-Integer Scaling Of Raster Images With Image Quality Enhancement

View page
US Patent:
6195473, Feb 27, 2001
Filed:
Dec 26, 1997
Appl. No.:
8/998545
Inventors:
Jack Zable - Niwot CO
Carroll Francis Hamill - Boulder CO
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06K 932
US Classification:
382299
Abstract:
A method for scaling an input bitmap by a non-integer factor with improved image quality comprises the steps of: selecting a pel in the input bitmap; selecting a neighborhood surrounding the selected pel; searching a set of image feature patterns to find an image feature pattern that matches the selected neighborhood; and writing a blocks of bits to an intermediate bitmap based on the match. The appropriate block of bits is obtained by subsampling an image enhancing tile which corresponds to the matched image feature pattern. The process of matching neighborhoods and writing a subsampled image enhancing tile (i. e. , block of bits) to the intermediate bitmap is repeated for each pel in the input bitmap. When the image enhancing tiles are subsampled to the proper size and shape and placed in the proper locations in the intermediate bitmap, the jagged "stair-step" look of curved and diagonal image features in the input image is smoothed, resulting in improved quality. The intermediate bitmap is then scaled down to a selected output resolution and written into an output bitmap with improved image quality and resolution greater than that of the input bitmap.

System, Method And Program For Converting An Externally Defined Colorant Cmyk Into An Equivalent Colorant (C'm'y'k') Associated With A Given Printer

View page
US Patent:
61375942, Oct 24, 2000
Filed:
Mar 25, 1997
Appl. No.:
8/823734
Inventors:
William Chesley Decker - Longmont CO
Ho Chong Lee - Boulder CO
Jack Louis Zable - Niwot CO
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B41B 1900
G03F 308
H04N 146
G06K 900
US Classification:
358 19
Abstract:
Disclosed is a method, system, and program for converting an externally defined four dimensional colorant, e. g. , CMYK, to an equivalent four dimensional colorant, e. g. , C'M'Y'K, having components of a printer. A measurement is made of first color values, e. g. , L. sup. * a. sup. * b, of a first set of patches having predetermined combinations of varying percentages of three primary colors, e. g. , CMY, printed by the printer. Each combination of known CMY values are correlated with corresponding color values, e. g. , L. sup. * a. sup. * b, as input to a first inversion program for determining CMY values for any given color value (L. sup. * a. sup. * b). A measurement is also made of second color values, e. g. , L. sup. * a. sup. * b, of a second set of patches having predetermined varying percentages of a fourth colorant (K) printed by the printer. The first inversion program is used to determine CMY values corresponding to the color values, L. sup. * a. sup.

Density Control For A Printer

View page
US Patent:
61476986, Nov 14, 2000
Filed:
May 29, 1997
Appl. No.:
8/865039
Inventors:
Jack Louis Zable - Niwot CO
William Chesley Decker - Longmont CO
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B41J 247
US Classification:
347240
Abstract:
A method and apparatus for controlling the density of the printed medium of a printer is provided and comprises the following steps. First a control strip is printed on the print medium having at least two coverage patches having a first and second different standard density. Next, the optical density of each of the patches are measured. Next a first and second tolerance limit is determined for the first and second patch, respectively. The next step is to determine whether the measured optical density of the first patch is within a first tolerance of the first standard density. If the first measured optical density is not within tolerance of the first standard density, then a change of at least one printer parameter is calculated such that the first density is corrected within the first tolerance. Then the effect of the change of the printer parameters on the second optical density is determined. If the second optical density with the effect is not within the second tolerance, then a change of at least one other printer parameter is calculated so that the second optical density with the effect is within the second tolerance, while the first optical density is still within its tolerance.

Postal Bar Code Printing With Engraved Character Impact Printer

View page
US Patent:
54154790, May 16, 1995
Filed:
Jul 9, 1993
Appl. No.:
8/089931
Inventors:
Robert F. Kuhn - Montrose PA
Ho C. Lee - Endicott NY
Jack L. Zable - Vestal NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B41J 500
US Classification:
400104
Abstract:
An impact printing device for printing postal bar code patterns on an information carrier. The patterns are a combination of parallel tall and short bars separated by spaces. The type elements are attached to a movable type carrier, each element comprised of pairs of vertical bars having different stroke lengths but equal widths. Additionally these elements contain overscored and/or underscored horizontal bars, that when printed appear outside the postal bar code clear space. This produces print elements that have nearly equal area and in turn produce printed characters of uniform stroke widths that are easily read by the U. S. Postal Service electronic readers.

System, Method, Program, And Print Pattern For Performing Registration Calibration For Printers By Measuring Density

View page
US Patent:
6198549, Mar 6, 2001
Filed:
Jul 31, 1997
Appl. No.:
8/903587
Inventors:
William Chesley Decker - Longmont CO
Ho Chong Lee - Boulder CO
Jack Louis Zable - Niwot CO
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H04N 146
US Classification:
358504
Abstract:
The system, method, program, and print pattern of this invention allows print misregistration to be detected and controlled through density measurements. A special print pattern is used for which a correlation between a density measurement of the print pattern and an amount of misregistration can be made. Initially, for a given printer, and for each printing station within the printer, the special print pattern is printed using two printing stations at varying amounts of misregistration of one of the printing stations. The density of each special print pattern printed at the varied amount of misregistration is measured. A correlation is made between density and amount of misregistration of the one printing station relative to the other printing station. Whenever misregistration is desired to be determined, the special print pattern is printed, the density is measured, and the correlation is applied to the measured density to determine a misregistration amount.

Paper Stacker Device For Receiving Fanfold Paper Without Assistance

View page
US Patent:
56036833, Feb 18, 1997
Filed:
Sep 14, 1994
Appl. No.:
8/308360
Inventors:
Ho C. Lee - Endicott NY
Larry T. Sehringer - Vestal NY
Jack L. Zable - Vestal NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B31B 110
US Classification:
493412
Abstract:
A paper stacker includes adjustable sides to receive paper passively of different widths. The uppermost ends of the sides are flared to avoid paper encountering these ends, permitting the received paper to slide down between the sides to settle on a bottom surface without assistance. Each of the sides has a portion cut away to permit grasping a paper stack for removal. A trapezoidal platform is located on the bottom between the sides and has a friction material on a substantially flat upper surface to prevent paper slippage.
