Abstract

The invention provides a bar code printing method. The bar code printing method comprises the following steps: firstly, solidly printing first bar code white stripes and second bar code white stripes on paper; secondly, hollowly printing third bar code white stripes; and finally, printing bar code black stripes at blank parts of hollow printing. According to the bar code printing method provided by the invention, hollow plate printing of a group of the bar code white stripes is added through paper making file processing, so that the covering capacity and smoothness of the original bar code white stripes are improved, and a black plate is much smoothly printed, thus the effect of stable bar code reading is achieved. In a plurality of examples, a great laser or light column effect of product paper is achieved through adopting the printing method; traditional printing of two groups of bar code white stripes and bar code black stripes cannot meet the printing requirement of a bar code, and hollow plate printing of a group of the bar code white stripes is added (the bar code printed with the black plate is hollowed), so that the surfaces of the parts printed with the white stripes are smooth, and the covering capacity is also improved; and qualified bar code reading and stable quality are achieved after the black plate is normally printed.

Description

A kind of bar code printing method

Technical field

The present invention relates to a kind of bar code printing method, belong to printing technology.

Background technology

With expanding economy, almost all of commodity all bar code graphical identifier as merchandise news is used, By one group, by necessarily regularly arranged width, the multiple patterns waiting and null pattern do not form bar code, in order to ensure commodity bar Shape code can be effectively recognized, and really plays its great function in business pos system it is ensured that the printing quality of bar code meets National standard, printing enterprise should strengthen the management to commodity bar code printing quality, and barcode quality is control effectively, It is not result in, because of blindness printing, a large amount of waste products occur, thus avoiding causing heavy losses to printing enterprise.

In recent years, with growth in the living standard, new requirement is proposed to various manner of packings, wherein various reflection effects Fruit very strong special paper such as gold silver paperboard, laser paper etc. are widely used in the packaging such as tobacco and wine class, various cosmetics and medicine, with Improve product specification, artistic effect and anti-counterfeit capability.At present, open surface printing bar code in gold, silver laser transfer paper easily to go out Show the situation that the unstable problem of reading or bar code thoroughly can not be identified, therefore one kind can improve bar code printing effect The research of process and with being just particularly important.

Content of the invention

In view of problem present in background technology, it is an object of the invention to provide a kind of bar code printing method, can make Make stay-in-grade bar code.

To achieve these goals, the invention provides a kind of bar code printing method:

Step one: field printing first bar code is white on paper；

Step 2: field printing second bar code is white on described paper；

Step 3: hollow printing Article 3 code is white on described paper；

Step 4: it is black that " empty " place of the hollow printing on described paper prints bar code.

Further, the color net of described hollow printing is that 45%-60% is hollow.

Further, print the black ink of described bar code and measure as 37%-41%, pressure is 0.1-0.2kg, and the moistening water yield is 23%- 25%.

Further, pressure during described hollow printing is 0.15-0.25kg, and ink is measured as 20%-30%, and the moistening water yield is 18%- 23%.

Further, adopt lithographic printing in described step one, in described step 2 and step 3, adopt flexographic printing, described Bar code printing is adopted in step 4.

The effect of the present invention is as follows:

The bar code printing method that the present invention provides, by file process of making a plate, increases by one group of bar code chronic leukorrhagia blind printing version, makes original Bar code increases covering power and flatness in vain, and black print stamps more smooth, reaches the effect of bar code stable reading.In multiple example In, using this printing process, product paper is radium-shine or light beam effect is very strong, and traditional two groups of prints cannot meet with black in vain The print request of bar code, plus one group of leakage dummy plate (by hollow for the bar code of print black print), make the white part surface of print smooth, and hide Lid power is also strengthened, and black print normally stamps that rear bar code reading is qualified and steady quality.

Brief description

Fig. 1 is embodiment of the present invention printing-flow figure.

Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the present invention, real technical scheme is clearly and completely retouched State.

As shown in Figure 1:

A kind of bar code printing method,

Step one: field printing first bar code is white on paper；

Step 2: field printing second bar code is white on described paper；

Step 3: hollow printing Article 3 code is white on described paper；

The color net of described hollow printing is hollow for 50%.

Print the black ink of described bar code and measure as 40%, pressure is 0.2kg, the moistening water yield is 25%.

Pressure during described hollow printing is 0.25kg, and ink is measured as 25%, and the moistening water yield is 20%.

Adopt lithographic printing in described step one, in described step 2 and step 3, adopt flexographic printing, described step 4 Middle employing bar code printing.

In addition to the implementation, the present invention can also have other embodiment, all employing equivalents or equivalent transformation shape The technical scheme becoming, all falls within the protection domain of application claims.
