Problems solved by technology

In order to save costs, the printing media is getting thinner and thinner, and due to mechanical design, mechanical assembly and platen wheel processing errors, etc., the printing media is inconsistent in different printing media positions. This inconsistency is very small, but in Under the high-precision inkjet device, the printing quality will be very poor, so it is very important to quickly and accurately detect whether the stepping of the inkjet printing device is accurate during the delivery of the inkjet printing device and the maintenance process of the inkjet printing device

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like figure 1 and figure 2 As shown, the inkjet printing device of the present invention comprises a printing carriage 2, a base plate 2 for installing an inkjet device is arranged on the printing carriage 2, at least one inkjet device is installed on the baseplate 2, and multiple inkjet devices are arranged on the inkjet device. A nozzle for ejecting ink droplets. The printing carriage 2 is installed on the guide rail beam 3, and driven by the drive motor 6, the printing carriage 2 reciprocates along the guide rail 4 installed on the guide rail beam 3 along the first direction (the printing head movement direction, that is, the main scanning direction), The printing carriage 2 is connected with the drive motor 6 through a combination of ...

Abstract

The invention provides an ink-jet printing apparatus. The ink-jet printing apparatus comprises a paper feeding device used for conveying a printing medium; an ink injecting device used for injecting drops of ink and provided with a plurality of ink injecting holes; a control system is used for controlling that the ink injecting device sprays a plurality of detection patterns onto a printing medium in the feeding direction perpendicular to the printing medium. The detection patterns are used to detect whether there are errors in the process of conveying paper. According to the invention, detection patterns are adopted to detect possible printing medium stepping errors and detection patterns are printed many times so that the errors are enlarged and that more accurate results are ensured.

Description

technical field [0001] The invention relates to the field of inkjet printing, in particular to a method for detecting the step error of an inkjet printing device and an inkjet printing device using the method. Background technique [0002] Inkjet printing technology refers to the technology of forming images or characters by ejecting ink droplets onto the printing medium. Because inkjet printing has the characteristics of non-contact, less pollution, and fast printing speed, it is now more and more used in industrial printing. In the roll-to-roll inkjet printing device, the printing medium is driven by multiple pickup wheels to make stepping motion , the wider the printing width, the more pickup rollers are needed. In order to save costs, the printing media is getting thinner and thinner, and due to mechanical design, mechanical assembly and platen wheel processing errors, etc., the printing media is inconsistent in different printing media positions. This inconsistency is ...
