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： 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： Printing can be properly performed on a print medium other than print media preset in accordance with print modes of a printer. Specifically, when the print medium other than the print media preset in accordance with the print modes is used, patches are printed on the print medium in each combination of the ink ejection amount and the number of passes, and information regarding each evaluation of granularity and banding based on colorimetry of the patches is obtained for each combination of the ink ejection amount and the number of passes. Next, a combination of the maximum ink ejection amount and the maximum number of passes is selected from the combinations that each evaluation of the granularity and the banding satisfies a certain level. Then, a print mode having a combination nearest the combination is selected from the plurality of print modes.

摘要： Disclosed are an image processing apparatus and method for the purpose of preventing overlapping of dots between two colors in low-density areas in color pseudo-grayscale processing, thereby obtaining excellent placement of the dots of each color. When a color image is binarized, an error is added to a respective one of color components (I0,I1), after which output decision means (2) decides an output value in accordance with the value of the sum in such a manner that the sum of pixel values after conversion will be rendered constant. Error calculation means (3-0, 3-1) calculate differences between pixel values before and after binarization as errors, and error diffusion means (9-0, 9-1) calculate values to be diffused to a neighboring pixel. Weighting coefficients used at such time are decided in accordance with combinations of values of the color components (I0,I1) of pixel values in the original image. The output value decided by the output decision means (2) is printed out by a printer or the like.

摘要： A printing apparatus and print control method, capable of using plural types of printheads, can achieve high throughput by performing optimized print control in accordance with the type of printhead and the number of printheads used. In a case where the printing apparatus adopting such print control method includes, e.g., four printheads, and performs printing on a print medium by reciprocally scanning the printheads, detection is first performed as to whether only one printhead which discharges black ink is mounted or four printheads which respectively discharge black, yellow, cyan and magenta ink are mounted; decision is made on a printing period of the printhead based on the detected result; then decision is made on a scanning speed of the printhead based on the decided printing period; and the printhead is driven based on the decided printing period and scanning speed to perform printing.

摘要： Each nozzle of an ink-jet head has heaters having different heating capacities, and in accordance with the heater driven, a diameter of an ink dot formed by ink which is discharged from the nozzle is changed, thereby printing a large dot or a small dot. When multi-value image data is inputted, the multi-value image data is modulated such that a pixel having high density is printed with both the large dot and small dot. On the basis of the modulated print data, any of the heaters included in each nozzle of the ink-jet head is driven, whereby printing an image having tones based on the multi-value image data.

摘要： Multi-valued image data is separated into data in units of nozzle groups of the individual colors of a printhead, and each divided multi-valued image data is converted into n-valued image data consisting of a plurality of bits. Based on the n-valued image data of the corresponding colors, print codes are generated and are transmitted to a printer apparatus. The printer apparatus receives the print codes, stores them in print buffers of the corresponding colors, and generates print data based on the print codes using mask patterns set in correspondence with image data of the individual colors. The print timing in each scan of the printhead is determined in accordance with the significant bit position in the print data, and an image is printed on the basis of the print data by multi-pass printing.
