摘要： An ink jet printing method is provided which, although it uses an ink jet print head with a fixed small ink ejection volume, can form an image with a desired density by performing data processing and printing at a lower pixel density. The dot arrangement pattern that determines the presence or absence of a printed dot in each of a plurality of element areas making up each pixel is allocated to the individual pixels according to their grayscale level. Then the printing dots are divided into a plurality of scans of the print head. At this time, for those pixels having a predetermined grayscale level, a plurality of dots are printed overlappingly in each of predetermined element areas of these pixels. This arrangement allows a greater number of dots than is determined by the allocated dot arrangement pattern to be printed in these pixels according to the grayscale level.

摘要： The present invention provides a method of printing a high quality color image with no color variations at high speed. For this purpose, this invention arranges in a main scan direction a plurality of print heads that eject different color inks, and reciprocally moves each of the print heads to perform a multipass printing in which a print operation is executed in both the forward and backward passes. During the multipass printing, the print duties of the print heads are set by mask patterns. Each of the mask patterns divides the print duty setting area for each nozzle group of each head into subdivided areas, sets the print duties of the subdivided areas to values different from each other and sets the print duties of the print heads to different values.

摘要： An ink jet printing apparatus capable of forming a high quality multivalued image without using a plurality of print heads and suited for a size reduction is provided. In an ink jet printing apparatus in which the electrothermal transducers are heated by a drive pulse to generate bubbles in ink and in which the pressure of the bubbles is used to eject ink droplets from nozzles onto a print medium to print an image, the drive voltage and the drive pulse width for the print head are changed simultaneously in accordance with print data. For example, when ejecting small droplets, the drive voltage for the nozzles is increased and the drive pulse width shortened. When ejecting large droplets, the drive voltage is lowered and the drive pulse width elongated.

摘要： When an image is sensed by a digital camera, image additional information as image sensing conditions is stored together with the sensed image information. Also, information unique to that digital camera is stored together with the image additional information. The digital camera is connected to a printer by, e.g., an IEEE1394 I/F. The printer stores printing control information as various combinations of unique information such as its printing method, the types of ink, the paper, and the like, the print quality and the print speed, and the processing technique, such as masking. In response to a print instruction, the printer reads the image information and image additional information from the digital camera, and selects the printing control information in accordance with the read information and the set printing mode. The printer prints an image using the selected printing control information.

摘要： A method for standardizing an ink jet recording head is arranged to be capable of utilizing the characteristics of each of recording heads to the maximum, while maintaining the compatibility between them. Particularly, the compatibility is maintained between the novel type recording head whose interior is partitioned into two layers through movable members, and a conventional type recording head. When the conventional type recording head is mounted on a novel type recording apparatus, all the requirements are handled by the novel type recording apparatus side to drive the conventional type recording head under a condition regulated for the conventional type recording head. When the novel type recording head is mounted on a conventional type recording apparatus, it is driven within the capacity of performance of the conventional type recording apparatus. A discriminator for discriminating the kind of mounted recording head is provided for each of the recording apparatuses. In this way, various control operations are attained. When the structure is arranged to use separate recording heads and ink tanks, the compatibility is maintained, while utilizing the difference in characteristics of the novel type recording head and ink, and those of the conventional type recording head and ink to the maximum by means of discriminating one kind of ink from another.

摘要： A method for preserving a liquid-ejection head is disclosed. The method uses the liquid-ejection head having a first liquid-flowing passage that receives a supply of a first liquid and communicates with an ejection port; a second liquid-flowing passage that receives a supply of a second liquid that differs from the first liquid; a bubble generation area formed on the second liquid-flowing passage for heating the second liquid to generate a bubble in said second liquid; and a movable member positioned between the bubble generation area, having a free end on an ejection port's side of the first liquid-flowing passage and a supporting end on other side of the first liquid-flowing passage, where the free end of the movable member is displaced toward the first liquid-flowing passage by a pressure caused by a generation of the bubble when said second liquid is heated. The method includes a step of performing a replacement of one of the fist liquid and the second liquid with the other at least at a periphery of the ejection port or a periphery of the movable member. Thus the liquid-ejection head is able to perform an excellent recording whether it has not been used for a long time.

摘要： The first print data indicating the discharging amounts of color and clear inks is generated in correspondence with an image to be printed with the color and clear inks. The second print data for designating a region for expressing decoration is generated. The discharging amount of the clear ink in the region for expressing decoration in the first print data is changed based on the second print data. Printing is done by scanning a printhead a plurality of number of times based on the changed first print data to execute the print scan of the clear ink after that of the color ink.
