摘要:
According to a method and apparatus for processing a color image, three primary color signals are input, and the input three primary color signals are processed to obtain three color reproduction signals and a black reproduction signal. In order to obtain the black reproduction signal, a value corresponding to a minimum value of the three primary color signals is obtained, and the value is transformed by a continuous function having a downwardly convex shape, thereby defining a transformed value as the black reproduction signal.

An image recording apparatus records an image on a recording medium by causing a recording head having an arrangement of a plurality of recording elements to conduct its main scanning for the recording medium interrelatedly in the direction opposite to the arrangement of the recording elements. The apparatus comprises a setting device to set the number of main scannings by the recording head; a main scanning device to perform recording by plural numbers of main scannings with respect to one pixel by causing the recording head to conduct its main scannings for the same recording area of the recording medium in accordance with the number set by the setting device; and a sub-scanning device to cause the recording head and the recording medium to be sub-scanned interrelatedly per main scanning in an amount smaller than the width of the arrangement of the recording elements of the recording head. Hence, even if a disabled ejection occurs in one scanning at the time of recording by a multi-scanning, the missing dot is complemented by the following scan to make it possible to obtain an image having no image defects at all times.
摘要:
An ink jet textile printing method forms an image on cloths in an image forming operation by repeating a step of applying ink on the cloths from an ink discharge port of a recording head, the recording head relatively main-scanning to form the image in a main scan direction, and a step of relatively conveying the cloths in a sub-scan direction. The method includes the steps of forming the image on the cloths by applying ink on the cloths from the recording head based on image data. The method further includes the step of temporarily stopping the image forming operation in accordance with an indication to effect a temporary halt of the image forming operation. When the temporary halt is indicated while the recording head performs a main scan in the image forming operation, the image forming operation by the main scan is completed, and then the temporary halt of the image forming operation is effected by moving the recording head to a standby position. The method still further includes the step of releasing the temporary halt of the image forming operation and restarting the image forming operation in accordance with an indication for releasing the temporary halt of the image forming operation. When the release of the temporary halt is indicated, ink is discharged from the ink discharge port and then the image forming operation is restarted.
摘要:
An image recording apparatus for moving, relatively to a cloth recording medium, a recording head for discharging ink so as to record an image. The image recording apparatus is arranged such that the operation conditions of the recording head can be changed at the time of the recording operation in accordance with the thickness of the cloth, or the diameter of the fiber or the pitch of weaving the fiber of the cloth, so that the quantity of ink to be supplied to the cloth to record an image is controlled so that a high quality recorded image can be obtained regardless of the type of the cloth.
摘要:
A recording apparatus for recording an image, by a recording device, on a recording medium having been conveyed to a position opposite to the recording device. The apparatus comprises a conveyor for conveying the recording medium to a recording region where a platen is disposed, a detector for detecting a floating amount and/or a floating angle of the recording medium with respect to the platen, and a selector for selecting either a first mode to continue the recording operation by varying the distance between the recording device and the recording medium in accordance with the detected result of the detector or a second mode to stop the recording operation. According to such a recording apparatus, it is possible to perform a high-quality recording operation since the distance between the recording head and the recording medium can be kept optimum.

An image recording apparatus records an image on a recording medium by causing a recording head having an arrangement of a plurality of recording elements to conduct its main scanning for the recording medium interrelatedly in the direction opposite to the arrangement of the recording elements. The apparatus comprises a setting device to set the number of main scannings by the recording head; a main scanning device to perform recording by plural numbers of main scannings with respect to one pixel by causing the recording head to conduct its main scannings for the same recording area of the recording medium in accordance with the number set by the setting device; and a sub-scanning device to cause the recording head and the recording medium to be sub-scanned interrelatedly per main scanning in an amount smaller than the width of the arrangement of the recording elements of the recording head. Hence, even if a disabled ejection occurs in one scanning at the time of recording by a multi-scanning, the missing dot is complemented by the following scan to make it possible to obtain an image having no image defects at all times.
