Description

Continuous conveying printing medium and scanning type multi-PASS printing output method and system

Technical field

The present invention relates to the field of printing technologies, and in particular, to a continuous conveying printing medium and a scanning multi-PASS printing output method and system.

Background technique

At present, there are two main ways of printing and outputting, one is scanning multi-PASS printing, and the other is ONE PASS continuous printing. Both printing output methods have their own advantages and disadvantages.

Scanning multi-PASS printing: The advantage of this printing output method is that after multi-PASS printing is superimposed, the color and the degree of reduction of the printed image are increased, the quality of the printing output is greatly improved, and the utilization of the printing nozzle is also improved. However, the shortcoming of this printing method mainly means that the printing medium must be intermittently conveyed, that is, after the printing medium has finished PASS, the printing nozzle moves along the X-axis direction while continuously discharging the ink to complete a PASS printing, and after the printing area is delivered. A PASS width print medium repeats the print transfer step to complete the printout. The method of intermittently conveying printing media, in the mechanism of conveying printing materials such as paper feeding system, paper feeding system, delivery system, etc., the friction and force of various printing media and conveying mechanism are complex and uncontrollable. The requirements for the design and assembly of the mechanism for transporting the printing medium are relatively high. Intermittently transporting the printing medium, due to the friction of the printing medium, the reaction force of the paper feeding system, the pulling force of the delivery system, etc., the length of the material transported between the multiple PASSs is not uniform, and the PASS channel cannot be effectively eliminated. The inconsistency of the same printing device on different printing media causes various limitations of the type of printing media when the device is in use.

ONE PASS continuous printing: The advantage of this printing output method is that the printing medium adopts a continuous conveying mode, so that the influence between various printing media and the conveying mechanism is minimized, and the printing medium is continuously conveyed, and the printing output speed is very high. Great improvement. However, this output method must use the print nozzle array to cover the entire print area, and the print material is conveyed while the print head is inked to complete the printing. The disadvantages of this method are as follows: 1. The lack of multi-PASS printing superposition process, the print output image There are obvious disadvantages in quality, color and reduction. 2. The print nozzle array is used to cover the print area. The print medium width has great requirements on the number of print nozzles, and the utilization rate of the print head is extremely low. 3. Due to the image, not all the nozzles of the printing nozzle can discharge ink, and the nozzles without ink discharge are easy to break the ink after a long time, which increases the design difficulty of the ink supply system and the quality requirements of using the ink. 4. The printing nozzle array is used to increase the complexity of the printing nozzle maintenance station system, and it is difficult to clean the printing nozzle at the same time.

It can be seen that the existing print output methods have their own advantages and disadvantages, and can not simultaneously take into account the performance of the printing device.

Example 3

As shown in FIG. 5, the present invention further provides a continuous transport printing medium and a scanning multi-PASS print output system. The third embodiment differs from the second embodiment in that the print head is moved forward and backward in the Y-axis direction, and the rest and the embodiment 2 The same, will not go into details here. The Y-axis direction front-back running device of the printing nozzle of the embodiment includes a Y-axis motor 14, a screw 15, and a second fixing member 16; the Y-axis motor 14, the screw 15, and the second fixing member 16 are disposed on the small frame 10, and the printing nozzle The Y-axis motor 14 is connected to the screw 15 through the second fixing member 16, and the control device controls the Y-axis motor 14 to drive the screw 15 to rotate, so that the printing nozzle moves along the screw 15 in the Y-axis, that is, the Y-axis direction of the printing nozzle.

The invention adopts continuous conveying printing medium and scanning type multi-PASS printing, and controls the movement of the printing medium by the control device in the Y-axis direction to control the movement of the printing medium, and combines the continuous conveying printing medium and the scanning type multi-PASS printing organically. This printout inherits the advantages of the traditional two independent methods, avoiding the deficiencies of the traditional approach.

1. Continuously transporting the printing medium, avoiding the deficiencies in the design of the mechanism, the assembly of the equipment, and the types of the printing medium by intermittently conveying the printing medium, and avoiding the problem of the PASS caused by the intermittent conveyance of the printing medium. However, the present invention uses relative motion between each PASS, and shortening the printing time improves the printing medium transport efficiency.

2, the use of scanning multi-PASS printing, to ensure the quality, color and reproduction of the printed output image. The print head can be moved to the outside of the print medium, and the spray nozzle can be used to avoid the phenomenon of ink breakage and plugging caused by the ink jet being discharged for a long time, and the use condition of the printing ink is lowered. The number of printheads is significantly lower than that of the ONE PASS printhead array, reducing the maintenance station system of the printheads. The multi-PASS superimposed printing method is adopted, which reduces the requirement of the inkjet state of the printing nozzle, and increases the use range and usage period of various printing nozzles.

In summary, the print output mode of the present invention controls the movement of the print head to synchronize the print medium by the control device, and combines the advantages of the above two. The conventional scanning multi-PASS printing output mode is avoided, and problems caused by intermittently conveying the printing medium must be used. The traditional ONE PASS continuous print output mode is also avoided, and the print head array must be adopted, the ink discharge state of the print head is required to be high, the print output quality is low, and the print head utilization rate is low.
