Problems solved by technology

That is to say, when many points are close to or overlapped, there will be a disadvantage that high-definition images cannot be obtained due to bleeding
Especially in the mixed part of the color or the connection part of the serial scan, the degradation of the image quality will be obvious due to the blurring of the outline

example 1

[0067] FIG. 4 is a perspective view showing an example of the ink jet printing unit 105 of the apparatus of the present invention.

[0068] Inkjet printing unit 105 is mainly made up of following parts: a frame 6, two guide rails 7,8, an inkjet head 9 and a support 10 for making it move, an ink supply device 11 and a for making it move Support 12, an inkjet head recovery device 13, and an electrical system 5, the inkjet head 9 includes several rows of discharge ports and converters for converting electrical signals into energy for ink discharge, and it also includes a mechanism, For selectively discharging ink through the discharge port arrays based on the image signal from the binary processing unit 103.

[0069] The inkjet head may be a printing head which uses thermal energy to discharge ink, and preferably includes a thermal energy converter for generating thermal energy to supply ink, so that the state of the ink changes due to the thermal energy provided by the thermal e...

example 2

[0078] Fig. 5 is a typical schematic diagram of a second example of a printing unit to which the method of the present invention is applied. The printing unit is mainly composed of the following parts: a cloth supply unit B, which is used to deliver the pretreated printing medium, such as cloth, rolled on a roller 33 ready for textile printing; a main unit A, when accurately fed For cloth, it prints the cloth with an inkjet head; and a winding unit C having a roller 39 for winding the printed cloth after the drying process. The main unit A also includes a precision feeding unit A-1 which includes a leveling and printing unit A-2. Fig. 6 is a perspective view showing the detailed structure of the printing unit A-2.

[0079] The operation of this device will now be described taking textile printing on pretreated cloth as the printing medium as an example.

[0080] The pretreated rolled cloth 36 is conveyed to the cloth feeding unit and reaches the main unit A. In the main uni...

Abstract

An object is to provide ink jet printed products superior in the image quality such that ink jet printing onto the cloths satisfy the various conditions regarding the density, resolution, blurring, graininess of dot. To accomplish this object, when an image is formed by a number of dots obtained by discharging the ink from a print head to attach the ink onto the cloths, the ink amount discharged from the printing head onto the cloths is controlled to produce ink jet printed products so that the average value of equivalent circle diameter for each dot after image formation may be three-fourths or less the average value of diameters of fibers constituting said cloths. Thereby, ink jet printed products excellent in image quality can be obtained with blurs reduced and high graininess of dot.

Description

[0001] This application is a divisional application of the patent application with application number 93108902.6, date of application on July 24, 1993, title of invention "equipment and method for manufacturing inkjet printed products and products manufactured by this method". Technical field: [0002] The present invention relates to an apparatus, a method for manufacturing ink-jet printed products, and ink-jet printed products manufactured by the method, which are printed by discharging ink onto a printing medium such as cloth made of cotton, silk, etc. was printed. It should be noted that the production equipment and method of the present invention can be used in offices, but is preferably used for industrial purposes. [0003] It should also be noted that the term "print" as used in this specification refers to textile printing. In addition, the term "fixing the colorant to the print medium" refers to coloring the print medium with a colorant or dye to such an extent that...
