Embodiment Construction
[0011] The technical scheme of the present invention is to print the typesetting diagram and the label pattern on the substrate together during printing, and a group of lines from thin to thick are printed on the blank position of the substrate according to the color of the ink ( figure 1 1) and a corresponding set of reversed lines ( figure 1 2) is the ink viscosity inspection line. During the inspection, as long as the printing status of each thick and thin line of the ink viscosity inspection line is clear or not, the ink viscosity during printing can be known and controlled in time to improve printing accuracy;
[0012] Print a short line perpendicular to the edge of the label on the edge of the label pattern, which serves as an anti-fall marking line ( image 3 ) with a line length of 3mm and a line width of 0.4mm, which is used for inspection of inverted labels when packaging. To inspect inverted labels, it is only necessary to observe from the side whether the anti-inve...

Abstract
Disclosed is a method for checking composing lines, which comprises: printing which is characterized in that, when printing label pattern, printing each color by a group of lines from thin lines to thick lines and a group of inverse edition line on the blank position of stock as printing ink viscosity detecting line; on the edge of the label pattern being printed a short line which is vertical to the edge of the label for checking inverse label; printing cross type line with frame on the cutting position and printing a cutting line which includes five straight lines, 1mm in general width, central straight line being long and two edge straight lines being shot, and the two ends being ladder type for verifying the cutting error; printing a solid equilateral triangle which has 1í½1.15mm length of edges on the position with distance to standard cut 0.4mm for checking cutting position.
Description
Technical field: [0001] The invention relates to an inspection method for printed labels and packaging bags. Background technique [0002] At present, there are many problems in the printing, post-processing and inspection of labels or packaging bags, such as the lack of intuitive judgment data for the control and inspection of ink viscosity during printing; there is no intuitive judgment standard for cutting and die-cutting, especially For the handling of some tolerance problems, it is still in the state of measuring edge thread, relying on experience, and feeling; the inspection of reversed labels is also very inconvenient, and needs to be turned over one by one. Not only is the speed slow, but it is also easy to cause labels to curl and affect production efficiency. and production pass rate. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a method that can visually represent the ink viscosity during printing,...
