Abstract: An online print system including a server and a print apparatus capable of communicating with the server via the Internet is provided. The print apparatus receives display page data from the server, analyzes the display page data and requests the server to print the display page data in accordance with link information included in the display page data. The server obtains the print page data using the link information, forms an index file including information indicating outlines of respective pages of the print page data, and transmits the index file to the print apparatus. The print apparatus receives the index file together with the print page data from the server apparatus and displays the index file. A page to be subjected to printing is designated on the basis of the displayed index file and the designated page is printed on the basis of the print page data.

Abstract: This invention allows both a plateless textile printer that makes process color expression, and a plate textile printer to achieve equivalent color expressions. For this purpose, image data that uses an RGB pallet is converted into YMCK image data using a correction table. An ink-jet textile printer (14) prints on textile on the basis of the converted image data. On the other hand, the image data that uses the RGB pallet is sent to a plate separation data generation unit (15), and is separated into binary plate data, the number of which is the same as the number of ink colors of the ink-jet textile printer, using an RGB/ink color tone correction table to realize the same color expression as that of screen textile printing.

Abstract: In an information processor, in which a user can only read simplified information, non-simplified information can be read and obtained on a printing medium by simple instruction.

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 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 is to perform complementary recording in order to eliminate the white streak caused by recording elements becoming incapable of recording while recording an image. Particularly, in an ink jet recording method for recording an image by discharging ink from nozzles, the white streak caused by nozzles becoming incapable of discharging ink can be eliminated by the performance of a complementary, recording in accordance with the present invention.Preceding printing, abnormal nozzles are detected, and then, data related to such abnormal nozzles are removed. In accordance with such data, one scan printing is performed. Preceding the returning operation of the printing head subsequent to the one scan, a sub-scanning feed is performed so that normal nozzles are positioned in a location corresponding to the white streak appearing in the one scan printing.

Abstract: A copying machine equipped with a recording apparatus having multi-nozzle heads for respective color components, cyan, magenta, yellow and black, is disclosed. The copying machine has a device which, if a non-ejecting nozzle is present in the head for black ink among the multi-nozzle heads, stores the number of the non-ejecting nozzle; and a recording control device which, when an ejection signal is given to the non-ejecting nozzle, causes a nozzle of each of the ink heads for cyan, magenta and yellow, the nozzle having the same number as the number of the non-ejecting nozzle, to eject ink.

Abstract: 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.

Abstract: An apparatus for performing the printing by scanning a carriage having a plurality of print heads mounted in a predetermined direction relative to the printing medium, so that an image is formed to have a desired color tone and density without decreased throughput. Conversion data for reproducing the color tone and the scan range of the carriage are changed in accordance with the used heads among the mounted heads. Also, the replaceability can be enhanced and the longer life for each group is attained by grouping the heads mounted. Further, the scan range of recording and the scan range for the recovery can be changed by selecting the group for use in accordance with the recording mode. Also, in an ink jet printing apparatus having a longer print length, a printing method for effecting the stable recording is provided.

Abstract: An image forming apparatus includes reading means for reading the density of a test pattern corresponding to each of plural recording elements of a recording head, the recording elements being arranged in an array, and the test pattern being recorded by the recording elements. An eliminating means eliminates error information, recorded from an area outside a test pattern are, from density information obtained by the reading means when the density of a test pattern end portion corresponding to an end portion of the array of plural of recording elements is determined. A means is provided for uniforming the image densities in correspondence with the plurality of recording elements based on density information from which the error information is eliminated by the eliminating means.

Abstract: An ink-jet print head comprises a plurality of heater boards as unit substrates which are connected to each other and each of which has a plurality of discharge elements arranged therein so that the nonuniformity of density which would ordinarily be produced in portions of the image printed by the head corresponding to boundaries between the respective heater boards is decreased. Since a plurality of ink-jet heads are disposed so that the boundaries between respective heater boards of the heads do not overlap one another, the potential nonuniformity of density at the boundaries can be decreased by interrelation between the heads.

Abstract: An ink-jet printing apparatus, having a first printing head at an upper position with respect to a cloth-conveying direction and a second printing head at a lower position with respect to the cloth-conveying direction, scans the printing heads in a direction orthogonal to the cloth-conveying direction. An image printed by the first printing head is complemented by the second printing head. If a stop of printing is instructed during the printing by the first printing head, the printing by the first printing head is stopped, and printing by the second printing head is continued until the position of the image printed by the first printing head is printed by the second printing head. In this manner, a printed image completed to the end of the image can be obtained.
