Abstract
An ink jet printing process for forming an image directly on a printing medium by an electrostatic ink jet method of ejecting an oil ink using electrostatic field based on signals of image data and preparing a printed matter by fixing the image and an ink jet printing apparatus comprising image-forming means of forming an image directly on a printing medium based on signals of image data and image-fixing means of fixing the image formed by the image-forming means to obtain a printed matter, the image-forming means being an ink jet drawing device of ejecting an oil ink from an ejection head using electrostatic field.
Claims17
An ink jet printing process for forming an image directly on a printing medium by an electrostatic ink jet method of ejecting an oil ink using electrostatic field based on signals of image data and preparing a printed matter by fixing the image, wherein the process uses:
- an ink tank for storing the oil ink;
- an ink circulation line for stirring the oil ink stored in the ink tank;
- and
- an ink feed line for feeding the oil ink to an ink jet ejection head, branched from the ink circulation line, and wherein the ink is circulated to the ink circulation line to simultaneously perform the stirring of the ink stored in the ink tank and the feeding of the ink to the ink jet ejection head.
An ink jet printing apparatus comprising image-forming means of forming an image directly on a printing medium based on signals of image data and image-fixing means of fixing the image formed by the image-forming means to obtain a printed matter, the image-forming means being an ink jet drawing device of ejecting an oil ink from an ejection head using electrostatic field, wherein the image-forming means comprises:
- an ink jet ejection head;
- ink feed means of feeding the oil ink to the ink jet ejection head;
- an ink tank for storing the oil ink;
- and
- ink circulation means of stirring the oil ink stored in the ink tank,
- and the ink feed means is branched from the ink circulation means.
