Ink jet printing method

Abstract

The invention discloses an ink jet printing method, which comprises: judging if the tail end, in the delivery direction, of a printing medium which is delivered in the delivery direction passes through a tail end detection sensor, and detecting the current position of the tail end, in the delivery direction, of the printing medium which is delivered in the delivery direction; reading a tail correcting value pre-stored in a memory; correcting the current position of the tail end to the tail end correcting position by using the tail end correcting value; detecting the current position of the left end, vertical to the delivery direction, of the printing medium which is delivered in the delivery direction; and reading the left end correcting value pre-stored in the memory. According to the method, the ink can be prevented from adhering to the tapes by detecting the tail ends of papers and cutting the images according to the tail ends of the papers. Besides, individual difference, such as the fluctuation of the sensor and the assembly fluctuation, can be overcome by computing the amount of stroke influence of a filler variable.

Description

technical field [0001] The invention relates to a printing method, in particular to an inkjet printing method. Background technique [0002] In recent years, printer technology has advanced rapidly due to the development of personal computers. A printer prints an image on paper based on image information. The printing apparatus for printers that has attracted the most attention in recent years is the inkjet printing system. Inkjet printing systems that print images by ejecting ink from a printing head onto paper have become popular. The advantages of inkjet printing systems are that inkjet printing systems can print high-resolution images quickly and are better than other printing methods in different aspects, such as running costs and quietness. [0003] Some inkjet printers write images on the printed paper by using a charged belt to attract the paper and make sure the printed paper is flat. In this type of inkjet printer, it is necessary to prevent ink from adhering t...

Problems solved by technology

[0007] However, in these schemes, when the sensor performance degrades and the detection results are wrong, it is impossible to obtain accurate tail position

[0008] In addition, the above-mentioned schemes only provide detection of the tail position of the paper conveying direction, fail to detect the left and right boundaries of the printed paper, and cannot fully detect the printable area of ​​the paper
