摘要:
In an apparatus for performing printing with a higher density ink and a lower density ink of the same color type, in order to prevent degradation of printing quality due to overlapping printing of the higher and the lower density inks, an input image signal is converted to an output image signal indicative of one of "non-printing" "printing with lower density ink" and "printing with higher density ink" is generated. More specifically, when printing is performed with two kinds of inks, i.e. the higher density ink and the lower density ink with respect to the same color type inks, the input image signal is subject of conversion process into three level data and two out of three levels are taken as printing signals of a head for ejecting the higher and lower density inks.

When a black image region is printed, the overall pixels in the region is printed by a black ink. Then, a cation type cyan ink which makes a coloring agent in the ink insoluble is printed on the pixels of a predetermined pattern. By this, the dye of the black ink is maintained near the surface of the printing medium to increase density of the black image. At the same time, for preventing variation of tone of the black image, the pixels of the predetermined pattern are printed by a yellow ink.

In forming an image with plural recording heads corresponding to plural inks of different densities, the image data are so distributed that the image is formed with the ink of low density until the image density reaches a predetermined density level, but is formed with the inks of low and high densities when the image density exceeds the predetermined density level, and the distributed data are corrected according to the detection of temperature relating to the recording heads, whereby a desired recorded image can be obtained even in the presence of a variation in the head temperature. Also the image data are distributed in such a manner that, when the remaining amount of one of the plural inks becomes low, the recording is conducted with the remaining ink, whereby a desired image can be obtained even when the remaining amount of one of the plural inks with different densities becomes low.

An ink jet recording apparatus uses a recording head having discharge ports to discharge ink, and records by discharging ink from the recording head while enabling said recording head to travel in the direction of main scan. This apparatus comprises a recording head which is provided integrally with a plurality of recording units having a plurality of discharge port arrays for discharging ink of different colors, respectively, and then, the plurality of recording units are arranged in the direction of main scan to discharge ink of different densities, respectively. With the structure thus arranged, the recording in all the colors is not executed at a time thus making it possible to obtain an excellent image with a lesser deterioration of image due to ink blur and the like.

A recording apparatus for performing recording on a recording medium by scanning the medium with a recording device having heads of a plurality of colors has a setting device for setting a color recording mode for recording a color image or a monochromic recording mode for recording a monochromic image, and a drive device having a first recording mode for driving the recording device while reducing a drive load on the recording device and a second recording mode for driving without reducing the drive load. The apparatus also has a determination device for determining the drive load with which the recording means is driven in a unit time on the basis of a data signal corresponding to a region of a scanning recording width of the recording device, and a changing device for changing the drive means into the first recording mode when the drive load determined by the determination device is large, and into the second recording mode when the drive load is small, if the color recording mode is set by the setting device.

A method for manufacturing thin film transistor array substrate for a liquid crystal display device-includes:—(a) forming a first metal thin film layer on a insulating substrate and forming a gate wiring and a gate electrode by a first photolithography. (b) forming a gate insulating film layer, a semiconductor film layer, an ohmic contact film layer and a second metal thin film layer, and forming the thin film transistor by a second photolithography, (c) forming an interlayer insulating film, and forming a pixel contact hole, a first contact hole and a second contact hole by a third photolithography, and (d) forming a transparent conductive film, and forming a pixel electrode by a fourth photolithography. The first metal thin film has a two-layered structure comprising a first layer made of aluminum or aluminum alloy and a second layer located on said first layer, and the second metal thin film is formed of an alloy mainly containing molybdenum.
摘要:
It is an object of the present invention to detect whether or not a conveying path is in a state capable of discharging a recording medium, having a recorded image thereon, outside of the apparatus, so as to prevent generation of a jam in conveyance and discharge of the recording medium. A state of covering a discharge port by a cover member is detected, and image recording on a recording medium is executed only when the recording medium can be conveyed and discharged. Non-execution of recording is indicated to an operator, and execution of recording is resumed when the cover member is moved to a state not obstructing conveyance and discharge of the recording medium.
