| 20090268219 | INK PRINT-THROUGH COLOR VALUE ESTIMATION METHOD AND APPARATUS, COLOR VALUE ESTIMATION METHOD AND APPARATUS TAKING INK PRINT-THROUGH INTO CONSIDERATION, TARGET COLOR SETTING METHOD AND APPARATUS TAKING INK PRINT-THROUGH INTO CONSIDERATION AS WELL AS CONTROLLING METHOD AND APPARATUS FOR PRINTING PRESS - The present invention relates to a color value estimation method and apparatus for a printing press which make it possible to estimate a color value with high accuracy taking ink print-through of a sheet-formed printed matter which is printed on the opposite faces. A one-face side picture data and the other face side picture data to be printed on a printing sheet are acquired, and a basic print-through color value from the other face side to the one-face side is calculated from the other face side picture data using a correlation relationship with a basic color value where one-face side with respect to the other face side picture data is blank. Then, the basic print-through color value is corrected based on the degree of the basic color value to the other face side picture data and the one-face side picture data corresponding to the other face side picture data to calculate a print-through color value. Further, a one-face side basic color value where the other face side of the printing sheet is blank is calculated from the one-face side picture data using the correlation relationship with the basic color value where the one-face side with respect to the other face side picture data is blank. Then, a one-face side color value, which includes a value by ink print-through, to be detected by a calorimeter is estimated from the calculated print-through color value and one-face side basic color value. | 10-29-2009 |
| 20100002246 | Printing simulation method and apparatus, picture color tone controlling method and apparatus for printing press, and printing press - A printing simulation method and apparatus, a picture color tone controlling method and method for a printing press and a printing press are disclosed by which, before printing is carried out, the color tone can be confirmed readily so that a demand for a print color tone can be satisfied precisely while appearance of broke is suppressed. A printing characteristic of a printing press and data of a printing picture to be printed by the printing press are acquired, and an image of the printing picture obtained by simulating color by the printing press with the data of the printing picture converted using the printing characteristic of the printing press is displayed on a monitor screen. Then, while a sample of the printing picture is referred to, correction of the color state of the picture displayed on the monitor screen with respect to the density of the ink color upon printing is carried out so that the color tone of the picture displayed on the monitor screen approaches the color tone of the sample picture. A target density is set in response to the correction, and printing is carried out while the ink supplying state by an ink supplying apparatus for each color is controlled so that the actual density of the color of a result of printing approaches the target density value. | 01-07-2010 |
