Barcode printing should pay attention to matters

In the bar code application system, the differences in the prices of goods and products are identified by different product codes. If two different goods are identified by the same code, the computer system treats it as the same product, resulting in errors in scan settlement and confusion in management.

2, amplification factor

The magnification factor actually refers to the size of the product barcode. Too large a commodity barcode will occupy too much space for packaging patterns or printed text, and it is not practical. Too small a size may easily cause difficulties in printing and reading. Therefore, the size of the bar code should be appropriate. According to the size of the outer package of the product and the area allowed for printing, the bargaining coefficient of the product bar code on the outer package of the product is in the range of 0.8 to 2.0, and the general amplification factor should be 0.9 to 1.2. For a bar code symbol of 0.8 to 0.9, quality control is more difficult and should be used recklessly.

3, empty color match

The empty color match refers to whether the contrast between the color of the bar code bar and the substrate color is in conformity with the standard. The commodity bar code is identified by the dedicated reading device relying on the lightness, darkness, and width of the resolution bar. Therefore, the greater the contrast between the bar and the empty bar, the better. In general, white is the bottom and black is the most ideal and safe color combination. Because the color itself can have a variety of changes, so in the choice of empty color match should master a principle: empty color as bright as possible, the color as far as possible no blue, black ingredients, strip color as deep as possible, the color should contain blue or black .

4, the printing position of product barcode

The printing position of commodity barcodes should be based on the principle that bar code symbols are not deformed and are easy to read. The greater the change in the placement of the product barcode on the product package, the slower the rate at which the cashier looks for the barcode and settles through the scanner and the lower the retail efficiency. Therefore, the printing position of the product barcode should be standardized as much as possible. For ease of scanning and settlement, the bar code of the product should normally be printed on the "natural" underside of the outer package.

5, product barcode truncation

In any degree, the truncation of the bar code symbol height of the product will affect the scanning and reading of the bar code. Therefore, the height of the product bar code symbol is strictly prohibited in principle.

6, left and right blank area

The dimensions of the left and right blank areas for merchandise and symbols should be sufficient to facilitate correct reading by the scanning device. It should be ensured that there are no characters, graphics, perforations, scratches, etc. in the left and right blank areas of the product barcode, and the printed position of the product barcode should also be far from the edge of the outer packaging of the product to meet the requirements for the blank area of ​​the barcode.

7, bar code printing on corrugated board

Printing barcodes directly on corrugated paper should pay attention to dimensional accuracy issues. Due to the uneven force during printing, the barcode is bent and degenerated. This problem is usually solved by printing barcodes on other carriers and then attaching them to corrugated packaging.
