| 20080231658 | PATTERN FORMING METHOD, LIQUID DROPLET DISCHARGING APPARATUS, AND ELECTROOPTICAL DEVICE - A pattern forming method forms a pattern on a substrate by relatively moving a plurality of nozzle groups each including a plurality of nozzles arranged in a first direction and the substrate a plurality of times in a main-scanning direction to allow the nozzles to discharge liquid droplets thereon. The method includes (i) relatively moving each nozzle group and the substrate in a sub-scanning direction such that a rear end of a former nozzle group overlaps a front end of a latter nozzle group when viewed from the main-scanning direction after every relative movement between the nozzle group and the substrate in the main-scanning direction; (ii) selecting a plurality of former nozzles among the nozzles of the former group that overlap those of the latter group to allow the selected former nozzles to discharge liquid droplets upon the relative movement between the former group and the substrate in the main-scanning direction; and (iii) selecting a plurality of latter nozzles positioned between the selected former nozzles among the nozzles of the latter group that overlap those of the former group to allow the selected latter nozzles to discharge liquid droplets upon the relative movement between the latter group and the substrate in the main-scanning direction. | 09-25-2008 |
| 20080238997 | HIGHLY INTEGRATED WAFER BONDED MEMS DEVICES WITH RELEASE-FREE MEMBRANE MANUFACTURE FOR HIGH DENSITY PRINT HEADS - A method of fabricating a MEMS inkjet type print head and the resulting device is disclosed. The method includes providing a driver component and separately providing an actuatable membrane component, the actuatable membrane component being formed in the absence of an acid etch removing a sacrificial layer. The separately provided actuatable membrane component is bonded to the driver component and a nozzle plate is attached to the actuatable membrane component subsequent to the bonding. Separately fabricating the components removes the need for hydrofluoric acid etch removal of a sacrificial layer previously required for forming the actuatable membrane with respect to the driver component. | 10-02-2008 |
| 20080316258 | Computer readable medium with a program for minimizing banding artifacts in an ink jet printing apparatus - A computer readable medium contains a program for causing a printer to execute a multipass printing method characterized in that, on any given pass, the number of selected print locations onto which printing ink is deposited by each of N nozzles varies from nozzle to nozzle. The variation is governed in accordance with a weighted smoothing spline function, particularly a polynomial B-spline function of the order “j”, where j is a value equal to one less than the number of passes. | 12-25-2008 |
| 20080316259 | Ink jet printing apparatus having a programmed controller that minimizes banding artifacts - A multipass printing apparatus is characterized by a computer-implemented controller that controls printing operation so that, on any given pass, the number of selected print locations onto which printing ink is deposited by each of N nozzles varies from nozzle to nozzle. The variation is governed in accordance with a weighted smoothing spline function, particularly a polynomial B-spline function of the order “j”, where j is a value equal to one less than the number of passes. | 12-25-2008 |
| 20090073226 | PRINTING APPARATUS AND DATA PROCESSING METHOD - In the case where a multipass printing and an interlace printing are used together, the present invention enables outputting an image of good quality independently of the relation between the number of passes in the multipass printing and increase in the resolution in the sub-scanning direction through the interlace printing. Data processing is executed while pixels of inputted image data are made to correspond to two or more rasters in the sub-scanning direction, so that the dots are arranged in these rasters at a substantially equal rate, in the case where the number of print scannings to be executed multiple times is not an integral multiple of the number of rasters. | 03-19-2009 |
| 20110012958 | Staggered Head Stitch Shifts in a Continuous Feed Direct Marking Printer - An imaging device includes an image receiving surface configured to move in a process direction in the imaging device. A plurality of printhead arrays are arranged to deposit marking material onto the image receiving surface. Each printhead array includes a plurality of printheads arrayed in a cross-process direction across the image receiving surface. Each printhead array includes at least one stitch line corresponding to a position along an axis parallel to the cross-process direction where an end of one printhead in the printhead array aligns with an end of another printhead in the printhead array. The at least one stitch line of each printhead array is offset a predetermined distance in the cross-process direction from the at least one stitch line of each of the other printhead arrays. | 01-20-2011 |
| 20120287203 | INK JET PRINTING APPARATUS AND INK JET PRINTING METHOD - Even if colors are printed in the same order for each band, time difference unevenness is suppressed which results from a difference in duration from the end of the first scan until the beginning of the second scan. An ink jet printing apparatus completely prints a scan area with a width corresponding to a predetermined length of a nozzle line. The ink jet printing apparatus includes conveying means for moving the print medium, generation means for generating print data in such a manner that in the two scans for completely printing the scan area with the width corresponding to the predetermined length, a print duty for the first scan is higher than a print duty for the second scan, and print control means for carrying out the first scan in an identical direction for all the scan areas completely printed by the two scans. | 11-15-2012 |
| 20130241997 | INK JET PRINTING APPARATUS AND INK JET PRINTING METHOD - The present invention provides an ink jet printing apparatus and an ink jet printing method which are based on the multi-pass printing method using a print head having a plurality of nozzle rows and which enables a reduction in the number of nozzles to be simultaneously driven, allowing ink to be stably ejected. On the basis of the multi-pass printing method of dividing print data into a plurality of pieces by using mask patterns, the mask patterns are offset according to the positional relationship between the plurality of nozzle rows in the print head. | 09-19-2013 |
| 20130250001 | REDUCED GLOSS BANDING THROUGH LOW INK VOLUME DEPOSITION PER PRINT PASS - Improved output quality of a printer used in UV curable ink jet printing is achieved by minimizing or eliminating a print artifact referred to as gloss banding or tire tracking. A same or a similar number of nozzles as used in conventional printers is used to achieve a desired throughput, but the nozzles are arranged so that any given square inch of substrate to which ink is being applied receives a lower amount of ink. A longer effective print head is provided by arranging the print heads into a longer array, where the print heads are butted substantially end-to-end. As a result, the net throughput of the printer is the same as that of a conventional printer because the printer uses the same number of print heads, but the amount of ink that is applied to any given square inch is less on a pass. | 09-26-2013 |
| 20140285576 | PRINTHEAD STRUCTURE - In one example, a printhead structure includes a cover covering an underlying structure. The cover and the underlying structure define multiple chambers from which fluid may be dispensed through nozzles in the cover and the cover has a stepped edge profile along at least part of the perimeter of the cover. | 09-25-2014 |
