The Method of Printing Barcode by Leakage Blank Plate

Abstract

The invention discloses a method for printing a bar code with a hollow white board. The method comprises the following steps: firstly printing a bar code hollow white board on paper to be printed, wherein the hollow part of the hollow white board is the white base color, and the bar part is a printed hollow white base color net; and then printing bars of the bar code on the hollow white base color net. According to the method, the contrast between the bar part and the hollow part of the bar code is obviously improved, and the recognition capability of a bar code detector is improved, so that the detection level of the bar code reaches to more than III. The original technology of printing bars after the solid white board is printed secondarily is replaced, and the original bars are easily influenced by the solid white board, so that the contrast between the bar part and the hollow part is relatively reduced. Meanwhile, printing twice is required when more than seven color groups are printed during the original secondary white board printing; and with the method, the problem that the color groups are insufficient can be solved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of barcode printing, in particular to a method for printing a barcode by using a blank plate. Background technique [0002] The reading of commodity barcodes is realized by the color contrast between the bars and spaces of the barcode. Generally, it can be used as long as the contrast requirements can be met. However, for special commodities such as cigarette labels and wine boxes, the barcode reading level must reach level 3 or above to be judged as qualified. On gold and silver cardboard and other special papers, the detection level of the white plate after printing once is often low, only 1.5- Around level 2, the method of printing the white plate twice is usually used to improve the barcode level. At present, the printing equipment generally has six color groups, which is suitable for printing with fewer colors, but when the packaging product reaches seven color groups, the machine color groups are not ...

AI Technical Summary

Problems solved by technology

At present, the printing equipment generally has six color groups, which is suitable for the case of fewer printing colors, but when the packaging product reaches seven color groups, the machine color groups are not enough, and it needs to be printed twice to complete it, which leads to low efficiency.

Although there are already printing equipment with more than six color groups, the purchase price is quite expensive, and for general enterprises, the production cost will increase significantly
