Abstract: In a normal record mode, a non-heat mode such that a non-ejecting pulse for heating is not supplied when the image recording is not executed is set. In a continuous magnify-record mode, a heat mode such that the non-ejecting pulse for heating is supplied when the image recording is not executed is set. Thus, a non-uniformity of an image density at the start and end of the recording can be suppressed and a reduction of the life of the head can be minimized.

Abstract: An image forming apparatus for forming an image in accordance with an input image on a recording material includes generating means for generating a predetermined pattern; superimposing means for superimposing the predetermined pattern on an input image; forming means for forming on the recording material the image superimposed with the predetermined pattern by the superimposing means; a controller for controlling an amount applied on the recording material of the predetermined pattern in accordance with the recording material.

Abstract: When an image is to be printed by the so-called multi-scanning method where image data corresponding to one band width is printed by a printhead scanning for a plurality of times, masking is performed on the image data in each of the scanning operation, and an image is printed on the basis of the masked image data. In such manner, pixels printed in each scanning form an image corresponding to one-scanning data (one band width of the data). At the time of printing by multi-scanning, a preliminary pulse is added prior to a driving pulse which drives the printhead so that the density of the image printed by multi-scanning is not decreased. In addition to changing such driving condition of the printhead, the density of the image data outputted to the printhead may be changed.

Abstract: 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.

Abstract: 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.

Abstract: An ink jet textile printing apparatus for performing printing by reading an original image created by a designer, converting the original image into original data represented by an electric signal, retrieving the original data for processing to be output as image data, and recording data on cloth based on the image data. The ink jet textile printing apparatus has a first ink jet recording head provided upstream of a recording position, and a second ink jet recording head provided downstream thereof, and is provided with a drying unit located between the recording heads, whereby high-quality recorded images with less bleeding can be obtained by recording on a recording area again with the second ink jet recording head after drying the recording area on the cloth recorded by the first ink jet recording head with the drying unit.

Abstract: A recording apparatus includes a recording unit having a nozzle line comprising a plurality of nozzles arranged along a sub-scan direction for recording a band having a record width corresponding to a length of the nozzle line onto a recording medium in accordance with an input image signal by discharging ink from the nozzles along a main scan direction orthogonal to the sub-scan direction, a transport unit for intermittently transporting the recording medium in the sub-scan direction, and a control unit for controlling the drive of the recording unit and the transport unit. The control unit sets a transport distance of the recording medium by the transport unit to a distance smaller than the record width when the image to be recorded on the recording medium comprises a plurality of bands. Each of the bands has at least one end having an image pattern complement to an image pattern at an end of adjacent band along the sub-scan direction.

Abstract: When a recording head having an arrangement of plural ejection portions for ejecting ink is moved for scanning, coefficients for the calculation of blur correction are set according to the number of nozzles used during scanning (magnification), and image signals corresponding to nozzles at scanning boundaries are corrected by an amount selected according to the set coefficients. This method makes it possible to always obtain a good image in which stripes formed at such boundaries are reduced even if image recording conditions are changed.

Abstract: 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.
