| 20090201331 | PRINTING METHOD, PRINTING SYSTEM AND METH0D FOR DETERMINING CORRECTION VALUE - A medium is carried to a predetermined position in a carrying direction. A first pattern is formed on the medium with nozzles on the carrying direction upstream side of a nozzle row constituted by a plurality of nozzles lined up at predetermined intervals. After forming the first pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row. Along with forming on the medium a second pattern that forms a boundary with the first pattern with nozzles on the carrying direction downstream side of the nozzle row, a third pattern is formed on the medium with the nozzles on the carrying direction upstream side of the nozzle row. After forming the second pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row so that a carry amount of the medium after forming the first pattern is longer than the length in the carrying direction of the nozzle row. A fourth pattern that forms a boundary with the third pattern is formed on the medium with the nozzles on the carrying direction downstream side of the nozzle row. | 08-13-2009 |
| 20100157342 | METHOD FOR MEASURING DENSITY, PRINTING METHOD, METHOD OF CALCULATING CORRECTION VALUE, METHOD OF MANUFACTURING PRINTING APPARATUS AND METHOD FOR OBTAINING CORRECTION VALUE - A method for measuring density, includes: forming on a medium a pattern that consists of a plurality of dot rows formed respectively in a plurality of row regions lined up in a direction intersecting a movement direction in which a plurality of nozzles move, by forming each of the dot rows in the row region arranged in the movement direction by ejecting ink from the nozzles; reading the pattern by a scanner; measuring density of each of the row regions of the read pattern; calculating respective modification values corresponding to each of the row regions, based on at least a part of a measurement result of the density of the plurality of the row regions; and modifying respective measured values of the density of each of the row regions based on the respective modification values corresponding to each of the row regions. | 06-24-2010 |
| 20100201733 | PRINTING METHOD, STORAGE MEDIUM, MEDIUM, PRINTING APPARATUS, METHOD FOR DETECTING END OF IMAGE, METHOD FOR DETECTING CARRYING UNEVENNESS OF MEDIUM, AND DEVICE FOR DETECTING CARRYING UNEVENNESS OF MEDIUM - A printing method according to the present invention includes carrying a medium, and printing, using a nozzle for ejecting ink, a plurality of images each having a section to be detected for detecting an inclination of the image with respect to the carried medium. | 08-12-2010 |
| 20100289842 | PRINTING METHOD, PRINTING SYSTEM AND METHOD FOR DETERMINING CORRECTION VALUE - A medium is carried to a predetermined position in a carrying direction. A first pattern is formed on the medium with nozzles on the carrying direction upstream side of a nozzle row constituted by a plurality of nozzles lined up at predetermined intervals. After forming the first pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row. Along with forming on the medium a second pattern that forms a boundary with the first pattern with nozzles on the carrying direction downstream side of the nozzle row, a third pattern is formed on the medium with the nozzles on the carrying direction upstream side of the nozzle row. After forming the second pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row so that a carry amount of the medium after forming the first pattern is longer than the length in the carrying direction of the nozzle row. A fourth pattern that forms a boundary with the third pattern is formed on the medium with the nozzles on the carrying direction downstream side of the nozzle row. | 11-18-2010 |
