Embodiment 1

[0060] Such as figure 1 Shown is a printing process abnormality detection method provided by Embodiment 1 of the present invention, and the method includes:

[0061] S101. Receive the standard detection parameter value sent by the terminal;

[0062] Wherein, the standard detection parameter value may be: a standard raster value preset at the interval between two inkjet trigger signals; or it may be: the maximum printing frequency of the nozzle.

[0063] S102. Determine the actual detection parameter value according to the inkjet trigger signal;

[0064]Wherein, the standard detection parameter and the actual detection parameter are used to detect whether an overclocking phenomenon occurs during the printing process, and the standard detection parameter value corresponds to the actual detection parameter value. For example, when the standard detection parameter value is: the standard raster value of the preset interval between two ink ejection trigger signals, the correspondi...

Embodiment 2

[0068] Embodiment 2 of the present invention provides another abnormality detection method in the printing process, such as figure 2 As shown, the method includes:

[0069] S201. Receive the standard detection parameter value sent by the terminal;

[0070] In this embodiment, the standard detection parameter value is: the standard grating value of the preset interval between two inkjet trigger signals; wherein, the standard grating value is specifically: R=4d / S, where R is the standard grating value , d is the precision of the grating ruler, and S is the horizontal precision of the printed picture. For example, if you want to print a picture with a grating ruler precision of 180dpi and a horizontal precision of 360dpi, the standard grating value is: R=4d / S=180dpi*4 / 360dpi=2, namely

[0071] During standard printing, it is necessary to generate an inkjet trigger signal every second raster value.

Embodiment 3

[0085] Figure 4 Another method for detecting abnormalities in the printing process provided by Embodiment 3 of the present invention includes:

[0086] S401. The terminal sends a standard detection parameter value to the printer;

[0087] In this embodiment, the standard detection parameter value is: the maximum printing frequency of the nozzle.

[0088] S402. The printer determines the actual detection parameter value according to the inkjet trigger signal;

[0089] Wherein, the standard detection parameter and the actual detection parameter are used to detect whether an overclocking phenomenon occurs during the printing process, and the standard detection parameter value corresponds to the actual detection parameter value.

[0090] In this embodiment, the standard detection parameter is the maximum printing frequency of the nozzle, and the corresponding actual detection parameter is: the actual spraying frequency. In this step, the actual spraying frequency can be determ...

Abstract

The invention discloses a printing abnormality detection method, device and system, and relates to the technical field of printing. The printing process anomaly detection method comprises the steps ofreceiving a standard detection parameter value sent by a terminal; determining an actual detection parameter value according to the ink-jet trigger signal; determining whether an overclocking phenomenon occurs in the printing process according to the standard detection parameter value and the actual detection parameter value. Through real-time comparison and judgment of the standard detection parameter value and the actual detection parameter value determined according to the ink-jet trigger signal, real-time detection of the printing abnormality caused by the overclocking phenomenon can be realized, and the instability that the printing abnormality needs to depend on human eye observation is solved; according to the invention, the printing abnormality caused by the overclocking phenomenon cannot be detected in time in the printing process is solved.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a method, device and system for detecting abnormal printing. Background technique [0002] With the wide application of computers in graphics or word processing, the application of printers has become more and more common. Through printers, people can easily output the text or graphics in the computer to pictures. [0003] In the current printing system, the printer issues printing instructions through the computer, and the printer prints the information sent by the computer. Common printers include inkjet printers and laser printers. Inkjet printers use nozzles to print, while laser printers use laser beams and photosensitive drums for electrostatic printing. Inkjet printers are widely used in industrial printing because of their cheap price. [0004] In the field of industrial printing, it is necessary to control various nozzles for printing, and each nozzle has its maximum...
