摘要： To reduce the number of simultaneously driven printing elements so that the instantaneously flowing current is restricted in a printing system for completing an image by repeating the printing scan a plurality of times in the same printing area while applying random mask thereto. For this purpose, a mask of a predetermined size is structured as a thinning pattern in which data are arranged randomly, the data being for determining whether or not the respective ink ejection openings in a printing head are to be driven when the printing head repeats the scan a plurality of times in the same printing area of a printing medium. When forming an image, the printing elements concerned with the printing operation in the same printing area are divided into a plurality of sections, and the thinning patterns complementary to each other are applied to the respective sections during the respective printing scans.

摘要： Print codes supplied from a host computer are received and analyzed to generate print data for the individual colors, and the generated print data are stored in print buffers corresponding to the colors. The print data corresponding to yellow ink with high lightness is expressed by binary data, and is printed by one dot per pixel by a single print scan. The print data corresponding to each of the remaining high-density (thick) inks is expressed by multi-valued data having a larger number of bits than the yellow data, and is printed by a plurality of print scans.

摘要： In a multi-scan method for printing a printing area by n (4) scans of a head and printing individual scan lines with n different ejection ports, a paper feed amount of transporting performed between the individual n scans is set to a value less than an amount of {(a length of total ejection port)/(n-1)}, and thereby close ejection ports in the ejection port arrangement in the head can be used as the n ejection ports for the individual lines, and an application position deviation between the ejection ports for individual lines due to a head mount error or the like can be reduced. As a result, unevenness of density due to deviation of dots in a scanning direction can be suppressed.

摘要： An ink is ejected at the same timing from ejection orifices in a number corresponding to an ink quantity 7% or less of an ink quantity ejected from all the ejection enabled ejection orifices of a plurality of ejection orifices of a recording head, and the ink ejection period from all the ejection enabled ejection orifices is set to be 70% or more of the driving period. Since the quantity of an ink ejected per unit time is minimized, and the negative pressure level generated in a common ink chamber can be set to be closest to normal pressure, the amplitude of a refill oscillation is minimized to stabilize ejection, and the driving frequency can be further increased.

摘要： An apparatus that includes a recording head having a plurality of recording elements arranged in a first direction is scanningly moved relative to a recording material in a second direction which is different from the first direction. The apparatus includes a motor driver for scanningly moving the recording head to the recording material in the second direction and a CPU/MPU for controlling driving of the recording head such that while scanningly moving the recording head in the second direction, the recording is effected such that a recording band region which extends into a second region and which is recorded using part of a continuous recording element and a non-recording band region which is not recorded, appears alternately, and by a different scanning movement, the non-recording band region is recorded. The recording band region and the non-recording band region have the same size.

摘要： In an image processing device for recording images with Y, M, and C color ink, a received Bk image is recorded with a color more similar to an original black color and solves a problem caused by too much amount of ejected ink such as bleeding with other colors or feathering. An image data consisting of four color elements of YMCBk is entered from a host computer, a Bk conversion unit converts the Bk element to respective Y, M, and C elements by masking of respective Y, M, and C elements generated randomly for the entered Bk element image data, and an image synthesizing unit synthesizes the converted YMC elements with the entered YMC elements. Then, an image recording unit for forming an image with three colors of YMC forms an image based on the synthesized YMC elements and records the image on a recording medium with ejecting YMC ink from a recording head.
