An ink jet printer for forming an ink jet printed long strip of cloth includes a design image generation unit, a receiving unit, a generating unit and a synthesizing unit. The design image generation unit generates design image data representing a design image repeatedly using a basic pattern. The receiving unit receives first designation data regarding a logotype mark, while the generating unit repeatedly generates logotype mark image data representing the logotype mark repeatedly using a logotype pattern independently from the repeated using of the basic pattern, in accordance with the first designation data received by the receiving unit. The synthesizing unit repeatedly synthesizes the design image data and the logotype mark image data in a fixed repetitive pattern and supplies the synthesized design and logotype mark image data to an ink jet head, so that an image including the design image and plural repetitive patterns of the logotype mark is printed onto the long strip of cloth along an elongated direction thereof by using the ink jet head.

When an magnified and synthesized image is finally printed on a printing medium based on an original image and a character font data, linear magnifying processing is executed with the aid of a software on the host computer side for the original image optically read by a scanner. In addition, vector magnifying processing is executed for font data likewise with the aid of a software, and moreover, synthesizing processing is executed for the font data. At this time, forming processing such as edge emphasizing or the like can be executed after completion of the vector magnifying processing. Synthesizing data are additionally magnified in a printer with the aid of a hardware, and subsequently, the magnified and synthesized image is outputted to the printer for performing a printing operation by the latter. An magnifying rate applicable to the host computer and the printer can be determined such that productivity of the image forming system is maximized.

Image forming system

An image output apparatus according to the present invention is able to additionally output another image data item to a desired position to which subject image data is outputted and able to repeatedly output the same image or repeatedly output the image while rotating the image. A setting unit sets the image repetition portion, the number of the repetitions and the rotation of the image. An image read by a reader is stored into a memory, and a reading counter changes the reading address of the memory in accordance with set information. Hence, a desired repeated image or the rotated image is outputted to a printer.

The invention is directed to a system including a host computer and a textile ink jet printer connected to each other via an interface. The system includes an input unit, a selection unit, an extraction unit, a designation unit and a print controller. The input unit inputs image data of a basic image, while the selection unit selects a design pattern for repeatedly arranging the basic image. The extraction unit extracts at least one design from the image data of the basic image. The designation unit designates whether or not to maintain the continuity of the extracted design in accordance with the selected design pattern, in a case where the ink jet printer restarts printing of the design pattern after interruption of a print operation of the design pattern. The print controller controls the ink jet printer to print the design pattern in accordance with a designation by the designation unit, in the case where the print operation of the design pattern is restarted. The continuity of printed basic images is controlled in accordance with the designation even if the print operation is interrupted.

Image forming apparatus for forming images with primary and secondary image data

A test image is formed by performing overlap printing using a plurality of printing heads provided for a printing agent of one color. Density data attained by reading this test image is averaged. On the basis of this average value, a common correction is performed for drive signals for the printing heads. This makes it possible to perform head density unevenness correction at a high efficiency in performing overlap printing by using the plurality of printing heads.

In a printing method which can suppress half band irregularity caused by 2-pass printing and implement high-image-quality printing, image data is distributed into two sets of data for front and rear heads, and each distributed data is distributed into two sets of data, i.e., forward print data and backward print data, thereby allowing 4-pass printing. An image on one line in the main scanning direction is formed by a total of four scanning operations, i.e., reciprocal printing by the front head and reciprocal printing by the read printhead.

Printing method and apparatus

An image processing system having an input/output unit for inputting or outputting a video signal, and a scanner for reading an original image or a printer for printing the video signal, in which the aspect ratio of the image is converted at the input or output of the video signal between the input/output unit and the scanner or the printer.

An ink-jet printed product is formed by printing an image with a plurality of similar color inks having different concentrations and a special ink having a single concentration. In the product, graininess resulting from ink dots is decreased for all hues of the printed image. A decision is made as to whether or not a hue of an image to be printed can be printed with inks without the special ink of a color (for example, special color BL (blue)) having a single concentration. When it is decided that the hue of the image is to be printed with inks without the special color ink, data on ink color BL (blue) is decomposed into data on C (cyan) and data on M (magenta). The hue can be printed without the color BL, thereby significantly decreasing graininess in a portion having this hue.

The present invention relates to an image processing apparatus and an image output apparatus that effects an image output operation by recording on a cloth recording medium. The image processing apparatus supplies first image data as original image data to the image output apparatus, and supplies second image data, different from the first image data, to be used for processing the cloth recording medium after the image output operation. The second image data can include a pattern for cutting or sewing the cloth. The apparatus further designates information associated with the second image data, so as to form the second image data on the cloth recording medium on which the first image data is recorded. The output of the first and second data is controlled in accordance with the designated information.

Textile image forming apparatus and method for forming original image data and secondary image data for use in post-processing

A high resolution head having smaller ejection amount and a low resolution head having larger ejection amount are employed. With respect to an image to be printed, an image separating portion separates a portion of a field in an image from a portion other than the field. For the field, printing is performed by the low resolution head through process of an image processing portion and a head control portion. As a result of this, for the field in the image, large dot is formed to reduce gap between the dots. Thus, color of the field can be uniform.

Ink-jet printing apparatus capable of increased image uniformity

An image processor performs image processing depending upon a plurality of data types such as additive color mixing type colors or substractive color mixing type colors. Other data types may be processed such as when extra colors are used other than yellow ink, magenta ink, cyan ink and black ink, in order to enhance image quality in an ink jet recorder, or in the event an ink color is arbitrarily changed or one or more types of ink colors are increased or decreased.

Image forming apparatus

The invention seeks to reduce amount of image data without detracting from picture quality, thereby lowering processing speed and holding down memory cost. While preserving the density of color image data, a computer compresses the color image data, which has been outputted by an image scanner, to a prescribed number of colors on the basis of the colors of inks. An image processor binarizes the results of compression, while preserving density, on the basis of ink colors. A main unit repeatedly prints a basic image, which is represented by the binarized image data, on cloth supplied from a supply unit.

Image processing apparatus and method, and method of manufacturing

An information processing apparatus applied to an image forming system, which can repetitively record a basic image, includes a device for obtaining a number of dots forming the basic image on the basis of the image data representing the basic image, and a device for estimating a consumption amount of an expendable consumed by recording an image of a predetermined unit on the basis of the obtained number of dots.
