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： This invention has as its object to realize multi-pass print control which requires a short processing time by a simple arrangement. To this end, a printer according to this invention attains multi-grayscale print control by changing the number of dots to be printed on each pixel to overlap each other in multi-pass print control that prints the pixel in a plurality of scans. In this case, index patterns, each of which designates which of scans is to be used to print in accordance with the density level of a pixel, are prepared for respective pixel values. If a plurality of patterns are prepared for each pixel value, a pattern is randomly selected from them. An image is printed in accordance with a print pattern defined by the selected pattern.

摘要： To achieve high-quality printing by controlling an ink-travelling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink is landed on a desired position of the printing medium effectively without disturbing the ink ejection, independent of a difference in the thickness of the printing medium. An electric field between a printing head and the printing medium is generated by applying a voltage to a platen of conductive material positioned immediately below the printing medium. At this point, the voltage applied to the platen is adjusted so that the electric field of a preferable intensity can be generated on a face of the printing head where ejection openings are formed irrespective of the thickness of the printing medium.

摘要： A printer having storing means storing time information indicating the time at which cleaning operations were last performed, with the initial value of time information stored in the storing means being set to a time later than the shipment of the printer. Elapsed time between the time information stored in the storing means and the current time is calculated when a user gives the printer an instruction to start printing operations. The printer performs suitable cleaning operation for a case wherein the calculated value of the elapsed time is negative.

摘要： In an image processing apparatus, a data amount of printing data generated for each different size of dot is reduced. Specifically, in quantization to obtain data for each printing head, printing data for a large dot is set as data in which a bit number per pixel is two bits, and printing data for a medium or small dot is set as data in which a bit number per pixel is one bit. Thereby, a data amount per pixel can be reduced compared with data in which all bit numbers per pixel for the large, medium and small dots are equally two bits.
摘要翻译：在图像处理装置中，针对每个不同大小的点生成的打印数据的数据量减少。具体地说，在为了获得每个打印头的数据的量化中，将大点的打印数据设置为每像素的位数为2位的数据，并将用于中点或小点的打印数据设置为数据，其中位每像素数为1位。因此，与大，中，小点的每像素的所有比特数相等地为2比特的数据相比，可以减少每像素的数据量。

摘要： The present invention can correct, when a printing position is displaced by an inclination of a printing head for example, the displacement in an easy and effective manner and also allows a user to easily recognize the displacement of the printing position to correct the displacement. To realize this, dots for forming a test pattern are formed by different scannings by a nozzle group including a plurality of nozzles positioned at one end side of a nozzle row and a nozzle group including a plurality of nozzles positioned at the other end side of the nozzle row. Depending on displacements of the printing positions of these dots, the plurality of nozzles constituting the nozzle row are divided to a plurality of divided nozzle groups. Then, the printing position is adjusted on the basis of the divided nozzle groups.
