Problems solved by technology

[0003] However, once the encoder and its installation mechanism are selected and designed, the encoder pulse signal output by the encoder will be fixed, but generally users require that the longitudinal accuracy be variable; in addition, the encoder installation mechanism will have certain structural limitations Accuracy error, such as: roundness, concentricity error, therefore, the existing encoding pulse signal may deviate from the design standard, thereby reducing the vertical printing accuracy, and the vertical printing accuracy cannot be changed, that is, it cannot meet the needs of users

Embodiment Construction

[0017] figure 1 It is a flowchart of an embodiment of the processing method of the printing accuracy of the present invention, such as figure 1 As shown, the execution subject of the method of this embodiment is a digital control system, then the method includes:

[0018] Step 101, according to the set frequency division value D and multiplication value M, and the obtained interval count value K at the current moment, formula (1) is adopted:

[0019] N=K×D÷M (1)

[0020] Obtain a counting reference value P, where the P is the integer part of the N.

[0021] In this embodiment, the first interval count value is greater than or equal to a preset threshold; the preset threshold is set according to accuracy requirements. For example, when the accuracy requires one thousandth, the preset threshold may be 1000.

[0022] Step 102, outputting a pulse signal according to the counting reference value P.

[0023] In this embodiment, whenever the output count reaches P, a pulse signa...

The method comprises steps as follows: obtaining a first count reference value P through a formula N=K*D / M according to a set frequency division value D, a frequency doubling value M and an obtained first interval count value K at a current moment, wherein the first count reference value P is an integer part of N, the first interval count value is larger than or equal to a preset threshold value, the preset threshold value is set according to a precision requirement, and a pulse signal is output according to the first count reference value P.

Description

technical field [0001] The invention relates to computer technology, in particular to a method and device for processing printing accuracy. Background technique [0002] At present, in the digital control system of inkjet printing, the encoder plays an important role without exception. In specific applications, according to the installation position and structure, the encoder can be divided into a pressure wheel encoder, a coaxial encoder and a servo encoder. Also, in all applications, the role of the encoder is to correctly reflect the displacement of the printed substrate. Specifically, digital inkjet printing is dot-matrix printing: the ink dot pitch in the direction perpendicular to the substrate is called lateral accuracy, which is determined by the physical characteristics of the inkjet print head; the ink dot pitch in the moving direction of the substrate Called longitudinal precision, the inkjet printing digital control system controls the longitudinal printing pre...
