摘要： An ink jet printing apparatus that improves the visibility of a character and its background in different colors or of outline characters is provided. Specifically, outline character bold data is inverted and each of the pixels in the data is expanded to adjacent eight pixels. Then, the expanded outline character is processed into expanded inverted data. The logical AND of the inverted expanded data and K data on a background image is then calculated to generate K data with the outline character expanded. This results in an image with the outline character expanded. That is, the present invention enables characters with improved visibility and free from blurredness to be printed while preventing the adverse effect of bleeding on the outline character.

A recording is accomplished by a liquid jet recording apparatus for ejecting a recording composition including dispersed fine particles from a small orifice toward a receiving medium, wherein a size Dp of the fine particles and a diameter Do of the small orifice are determined by a relationship 0.001≦Dp/Do≦0.01.

摘要： To provide an ink jet head capable of performing proper image forming operations by easily removing air bubbles contained in ink. A manifold 13, 14 is formed with an ink supply channel 41. A plurality of openings 45 are formed at one edge of the ink supply channel 41. The openings 45 are fluidly connected to ink channels 31. The openings 45 have a smaller dimension toward the ink channels 31. During purging or flushing operations, an air bubble EB in the ink supply channel 41 is pulled toward the ink channels 31 while gradually changing it outer shape in the opening 45. In this way, the air bubble is smoothly and easily pulled into the ink channel 31, and ejected through a nozzle 16a.

摘要： Heating elements are driven to continuously perform a dummy jet when the number of accumulated printed sheets reaches a predetermined number that causes the image quality deficiency. The surface temperature of a recording head is increased to T1° C. to boil ink in the individual channel. A bubble attached to the common liquid chamber side edge of the individual channel is spaced from the wall surface to be expanded to be integrated with other bubbles, and then, is discharged from the common liquid chamber to an ink supply chamber by its floating force. The bubble can be removed reliably.

摘要： A liquid ejecting method for ejecting liquid by generation of a bubble includes preparing a head comprising an ejection outlet for ejecting the liquid, a bubble generation region for generating the bubble in the liquid, a movable member disposed faced to the bubble generation region and displaceable between a first position and a second position further from the bubble generation region than the first position; and displacing the movable member from the first position to the second position by pressure produced by the generation of the bubble in the bubble generating portion to permit expansion of the bubble more in a downstream side nearer to the ejection outlet than in an upstream side.
