Printing control method and printer

The invention discloses a PS (Presensitized Plate) plate surface detection system based on machine vision, and relates to the field of industrial automation technology. The system comprises image acquiring equipment, image processing equipment and system lighting equipment, wherein the image acquiring equipment is used for acquiring the information of the original image of the upper surface of a PS plate; the image processing equipment is used for processing the original image information acquired by the image acquiring equipment in order to distinguish the defects on the upper surface of the PS plate; and the system lighting equipment is used for providing imaging light to the image acquiring equipment during acquiring the information of the original image of the upper surface of the PS plate. By adopting the PS plate surface detection system based on the machine vision, provided by the invention, the PS plate detection process can be carried out in a mechanical automatic detection way in stead of a manual detection way, and thus the purposes of reducing the omission factor, decreasing the cost and improving the precision and production efficiency during detecting the PS plate can be realized.

A printer and a control method of a printer can print barcodes appropriately according to a given print medium by means of a simple, easy operation. The printer stores a constant preset value relationally corresponding to each type of print medium. The printer also stores an added correction value that is optionally input for each specific type of print medium. The constant value and the added correction value are used to adjust the printed state of the barcode, e.g. to adjust bar widths within the barcode. The print control unit prints barcodes using the constant value stored in the printer storage unit adjusted with the added correction value.

CTP (Computer to Plate) plate surface detection method and system based on machine vision

The invention discloses a paper eliminating processing method and a device. The paper eliminating processing method comprises the following steps: acquiring the quality parameters of paper in the process of manufacturing paper with pulp; comparing the quality parameters with preset threshold values; if the quality parameters exceed the range of the threshold values, spraying quality identification codes on the paper; acquiring the quality identification codes of the paper in the process of cutting the paper; and carrying out eliminating processing on the paper according to the quality identification codes of the paper. Thus, the paper eliminating processing method and device of the invention can carry out automatic identification and elimination on the paper of which the quality parameters exceed the range of threshold values, thereby improving the production quality of paper on the basis of low economic cost and time cost.

Paper eliminating processing method and device

The invention discloses a code spraying system. The system comprises a horizontal positioning device, a longitudinal positioning device, a quality detection device and a spraying device, wherein the horizontal positioning device is used for identifying transverse label information of paper and generating code spraying horizontal position data according to the transverse label information; the longitudinal positioning device is used for identifying longitudinal label information of the paper and generating code spraying longitudinal position data according to the longitudinal label information; the quality detection device is used for detecting the quality of the paper and generating quality detection data of the paper; and the spraying device is used for spraying an identification code corresponding to the quality detection data at the position, corresponding to the code spraying horizontal position data and the code spraying longitudinal position data, of the paper. The code spraying system of the invention can detect the quality of the paper, and then sprays the quality identification code at the spraying position of the paper according to the specific condition so as to realize convenient and effective labeling and improve the production quality and management level of the paper.
