摘要： In a printing apparatus improvement of drying ability and reduction of consumed power are concurrently achieved by improving the efficiency of drying ink. More concretely, hot air is blown onto a print medium printed by ink, and a portion of the blown hot air is recovered and blown again. Before the hot air is blown, the print medium is heated by a preheating unit, making it higher than the dew point temperature of the blown hot air.

摘要： A printing apparatus prints on a printing medium by using a printhead which has a first nozzle array including a plurality of nozzles from which a first nozzle amount of the ink is discharged and a second nozzle array including a plurality of nozzles from which a second nozzle amount of the ink is discharged. This printing apparatus time-divisionally drives a plurality of blocks obtained by dividing each of the first nozzle array and the second nozzle array. The printing apparatus selects, from the first nozzle array and the second nozzle array, a block to be driven by the driving unit within a predetermined period. This printing apparatus controls the selection unit to alternately select a block from the first nozzle array and the second nozzle array and sequentially select a block from each nozzle array in a predetermined order.

摘要： An ink-jet recording device is capable of correcting a recording position due to a leaning of a printing head and correcting of driving timing between multiple printing heads. Each nozzle row of a printing head is classified into multiple nozzle groups, and the driving timing of the nozzle groups other than the nozzle group serving as a reference of correction of the multiple nozzle groups is adjustable to correct for any leaning of the printing head. Moreover, in the event of performing the driving timing between printing heads, the driving timing of a non-reference printing head is adjustable relative to a reference printing head employed for leaning correction of multiple printing heads.

摘要： In an image printing apparatus for printing an image by combining dots of a plurality of sizes, a banding problem attributable to variations in conveying operation, and a temperature rise of a print head with an increase of the number of ejections are solved with a relatively simple configuration. To this end, a combination of dots of a plurality of sizes is assigned to each of pixels expressed at a plurality level of density. In this assignment, a dot larger than a pitch of an image resolution is preferentially allocated to a pixel having a density level higher than that to which one dot smaller than the pitch of the image resolution is allocated.

摘要： Provided is a print position control method whereby displacement of a print position in a wide range can be corrected very accurately, without reducing a printing speed or increasing a manufacturing cost. Thus, a printing apparatus includes: a first correction unit, for correcting a print position at accuracy equal to the resolution of the printing apparatus; and a second correction unit, for correcting the print position at accuracy higher than the resolution and in the range of an area that corresponds to one pixel of the resolution. With this arrangement, the print position displacement in a wide range equal to or greater than one pixel can be corrected by the first correction unit, and a print position displacement smaller than one pixel can be corrected by the second correction unit. Therefore, correction of a print position displacement in a wide range is enabled at a higher accuracy.
摘要翻译： 提供一种打印位置控制方法，可以在不降低打印速度或增加制造成本的情况下，非常精确地校正大范围内的打印位置的位移。 因此，打印设备包括：第一校正单元，用于以与打印设备的分辨率相等的精度校正打印位置; 以及第二校正单元，用于以高于分辨率的精度和对应于分辨率的一个像素的区域的范围来校正打印位置。 利用这种布置，可以通过第一校正单元来校正等于或大于一个像素的宽范围内的打印位置位移，并且可以通过第二校正单元校正小于一个像素的打印位置位移。 因此，可以更高精度地进行宽范围内的打印位置位移的校正。

摘要： When conveying tables for conveying the printing medium are selected to perform interlace printing, the occurrence of unevenness in an image which results from switching of the tables is prevented. It is determined whether a phase of the conveying table is a transfer inhibition phase in transfer to a printing area. In the case of the transfer inhibition phase, the switching is not made to a new table, but the previously used table is used. Thus, the switching can be made to a conveying table so as not to make a shift amount +1/2N or −1/N continue. Consequently, it is possible to prevent the occurrence of unevenness in an image which is caused by 1/N deviation of a printing position in a sub-scanning direction with regard to print data at the time of transfer from a rear end area to the normal area or the normal area to the rear end area.
摘要翻译： 当输送用于输送打印介质的台用于执行隔行打印时，防止了由于桌面的切换而导致的图像不均匀的发生。 确定传送台的相位是否是传送到打印区域的传送禁止阶段。 在转移禁止阶段的情况下，不对新的表进行切换，而是使用先前使用的表。 因此，可以进行到输送台的切换，使得不会使移位量+1 / 2N或-1 / N继续。 因此，可以防止在从后端区域传送到正常时的打印数据时在副扫描方向上的打印位置的1 / N偏差引起的图像不均匀的发生 区域或后方区域的正常区域。
