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.

摘要： Random masks each having a given size and defining a random array of non-record pixel locations and record pixel locations are placed in association with record areas in mask registers. Using the placed masks, record data is thinned-out and supplied to a recording head. An image is then recorded. Thus, since thinning-out masks do not have periodicity, any inherent density nonuniformity loses periodicity. Consequently, high-definition images can be produced.

摘要： In image recording by discharging plural inks of different characteristics onto a recording medium, recording pixels to be recorded by at least one of the inks of either yellow, magenta or cyan color subjected to pixel expansion are expanded in four direction, then a logic product is calculated between the expanded pixels and the pixels to be recorded with an ink which is black not subjected to pixel expansion, and the recording pixels to be recorded by the ink which is black not subjected to pixel expansion are replaced by the pixels formed by the inks (Y, M, C) subjected to pixel expansion. Thus high-quality image recording is made possible even in case the inks of different properties are brought into mutual contact.

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.
摘要翻译： 在与喷墨孔相同的时刻，墨水以对应于从记录头的多个喷射口的所有喷射口喷出口喷出的墨量的7％以下的墨量喷射，喷墨 所有喷射启动喷射口的时间段被设定为驾驶时间的70％以上。 由于每单位时间喷射的墨量最小化，并且可以将普通墨水室中产生的负压水平设定为最接近正常压力，因此使再充电振动的振幅最小化以稳定喷射，驱动频率 可以进一步增加。

摘要： According to this invention, upon execution of recording by ejecting an ink droplet from a recording head, a surrounding temperature sensor for measuring the surrounding temperature is provided to a main body side, and a change in temperature of the head is presumed from the past to the present time by calculation processing, so that optimal temperature control can be performed without arranging a head temperature sensor having a correlation with the head temperature. At this time, the ejection quantity can be stabilized by changing the pulse width of a driving signal on the basis of the presumed head temperature, and ejection can be stabilized by performing restoration processing.
