Analyze factors affecting bar code levels

Here are a few factors that affect the bar code level. First, the color bar is empty and color matching. When matching with the air, you must ensure that the contrast of the color of the strip is large enough. The color of the strip can be: dark blue, dark green, dark brown, black, and the empty color can be red, orange, yellow, white, and the best in black and white.

Here are a few factors that affect the bar code level.

First, the color

Empty color matching. When matching with the air, you must ensure that the contrast of the color of the strip is large enough. The color of the strip can be: dark blue, dark green, dark brown, black, and the empty color can be red, orange, yellow, white, and the best in black and white.

Gold, silver is not available.

When printing bar code symbols on transparent materials (such as plastic, glass, etc.), you cannot print only the color of the bar, but not the background color (empty color). Otherwise, the scanner cannot acquire an empty reflected signal and cannot read it. Therefore, the bar code printed on the transparent material must first be pre-printed.

Second, the size

According to the size of the outer packaging and the area allowed for printing, the bar code magnification factor is selected within the range of 0.8-2.00 times the standard bar code size (the standard bar code refers to the bar code with the magnification factor of 1.00, and its size is 37.29*26.26 mm).

The bar height of the bar code: the height cannot be less than 1/3 of the standard height.

The left and right margins of the bar code: the security range of the bar code, which needs to be more than 2.5 mm from the edge.

Third, the location

The position of the bar code symbol should be determined in accordance with the principle of non-deformation and easy reading.

The barcode surface curvature should not exceed 30 degrees.

Bar codes cannot be placed in a tangential position.

The bar code shall be at least 5 mm from the edge, overlap, wrinkle or corner of the package.

The bar code rating refers to the quality of the printed or printed bar code.

Therefore, the design of qualified barcodes mainly depends on the effect of printing or printing.

CORELDRAW cannot control the level of the bar code.

Software such as CORELDRAW cannot guarantee the correct scaling of the barcode. Therefore, barcodes that may cause good printing or printing effects are not scanned.

There are many possibilities for not going to the bar code level:

1, the use of bar code editing software problems, such as the software itself, the bar code is not standard and other factors, what bar code software you use.

2, printing method, are you printing with a bar code printer, or printing presses, if you use a label printer, and with the bar code software that comes with the bar code machine, as long as the quality of the consumables is not too bad, the bar code level printed Generally can reach C or above.

3, typesetting problems, this is actually a bar code design software problem.

All bar code software can't control the bar code level, even the professional bar code editing software will not work. If it can be controlled, no one will buy a bar code detector to check whether the bar code level is qualified.
