Description

Engraving plate special for bar code printing

Technical Field

The utility model relates to the field of printing technology, especially a special engraving of bar code printing.

Background

Intaglio printing is a direct printing method, which directly imprints the ink contained in the intaglio pits on a printing stock, wherein the shade level of the printed picture is determined by the size and the depth of the pits, if the pits are deeper, the contained ink is more, and the ink layer left on the printed matter after impressing is thicker; conversely, if the pit is shallow, the amount of ink contained is small, and the ink layer left on the substrate after the imprint is thin. The intaglio printing plate is composed of pits corresponding to the original pattern and the surface of the printing plate. When printing, the ink is filled into the pits, the ink on the surface of the printing plate is scraped by the doctor blade, and the printing plate is in certain pressure contact with the printing stock to transfer the ink in the pits to the printing stock to finish printing.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will explain specific embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and for a person skilled in the art, other drawings and other embodiments can be obtained without inventive effort, and the invention is not limited to this example.

Referring to fig. 1 to 5, the engraving plate for printing a barcode according to an embodiment of the present invention is a laser etching engraving plate, and sequentially includes a bottom plate, a copper plating layer, a chromium plating layer, a heat insulating layer and an insulating surface layer, the insulating surface layer is provided with an ink groove with a thickness of 0.01mm, the number of dots of the engraving plate is 30-80 lines/inch, the depth of the dots is 30-100, and the shapes of the dots include a quadrangle and a hexagon.

And sending the screened image-text signals to a laser modulator, enabling laser to act on the engraving surface layer, inputting set process parameters according to process requirements, converting the image-text information of the manufactured laser file into electric signals, and driving a laser head to etch the electric signals on the surface layer photosensitive adhesive. After the laser engraved printing plate is developed, the glue of the image-text part is reacted, the non-image-text part is remained, and the image-text information is solidified on the printing plate. And carrying out corrosion reaction according to the requirements of the corrosion process, and corroding for different time according to the requirements to form mesh point pits with different sizes on the engraving plate.

The laser engraving process overcomes the defects of hair and weakness of the traditional engraving characters and thin lines, and has the characteristics of high ink content, thick color, clear handwriting and durability.

The edge of the bar code bar is carved with an ink groove with the thickness of 0.01mm by a laser grooving process, and only vertical scratch is processed in order to prevent knife hitting phenomenon in consideration of the knife facing surface of printing, so that the edge of the bar code is smooth, and the probability of burr occurrence of the edge of the bar code is reduced.
