Abstract
A color image forming system allows color image formation using a color (special color) except for yellow (Y), magenta (M), cyan (C), and black (BK) normally used in color image recording. Palette tables in which data defining use of the special colors (S1 to S4) in addition to Y, M, C, and BK are supplied from a host image data supply apparatus to a printer. At the same time, image data is transmitted in the form of data for allowing selection of the defined data in the palette tables. The printer uses Y, M, C, and BK heads and heads of the special colors S1 to S4. A control unit in the printer stores each palette table for each color (508) and outputs a driving signal to the corresponding head on the basis of the corresponding palette table.
Claims18
An image forming apparatus for forming an image on a cloth using recording means, said image forming apparatus having main-scan means for scanning the recording means for performing recording at a predetermined width along a main-scan direction and sub-scan means for feeding the cloth along a sub-scan direction perpendicular to the main-scan direction, said image forming apparatus comprising:
- means for inputting a user's instruction of a type of the cloth;
- a memory for storing an adjustment amount of feed quantity corresponding to the type of the cloth, the adjustment amount being an amount for adjusting a difference of feed quantity based on an elasticity of the cloth itself that differs in accordance with the type of the cloth;
- setting means for setting a feed quantity for the sub-scan means in accordance with the instructed type of the cloth, wherein said setting means sets the feed quantity by referring to the adjustment amount stored in said memory;
- and
- image forming means for forming an image on the cloth based on input image data, the image forming being performed by repeating an operation for forming an image by the recording means based on the image data during scanning of the recording means by the main-scan means and an operation, to be performed after a scan in the main-scan direction, for feeding the cloth by the sub-scan means based on the feed quantity set for the sub-scan means.
An image forming method for forming an image on a cloth using recording means, main-scan means for scanning the recording means for performing recording at a predetermined width along a main-scan direction, and sub-scan means for feeding the cloth along a sub-scan direction perpendicular to the main-scan direction, said image forming method comprising the steps of:
- inputting a user's instruction of a type of the cloth;
- setting a feed quantity for the sub-scan means in accordance with the instructed type of the cloth, wherein the feed quantity is set by referring to a memory for storing an adjustment amount of feed quantity corresponding to the type of the cloth, the adjustment amount stored in the memory being an amount for adjusting a difference of feed quantity based on an elasticity of the cloth itself that differs in accordance with the type of the cloth;
- and
- forming an image on the cloth based on input image data, the image forming being performed by repeating an operation for forming an image by the recording means based on the image data during scanning of the recording means by the main-scan means and an operation, to be performed after a scan in the main-scan direction, for feeding the cloth by the sub-scan means based on the feed quantity set for the sub-scan means.
