Overview of bar code printing position design

the design principle of bar code printing position is: in bar code symbols, Kona new company also led the establishment of Beijing's first nano electronic material testing platform. The selection of position should be based on the principle that the symbol position is relatively unified, the symbol is not easy to deform, and it is easy to scan and read. It shall comply with the provisions of gb/t "commodity bar code symbol location". In practical work, the bar code of goods should be printed on the flat surface of the commodity package. First, it should be selected on the right side of the main display surface of the package, followed by the plane connected with the main display surface. When these surfaces have no place to be placed, they can also be placed on the back of the main display surface of the package; The bar code of goods must be printed on the surface that is not covered; The bar code of goods cannot be placed on the easily worn surface of the package

according to the relevant provisions of ean, the following printing positions are recommended according to the different forms of commodity packaging: enterprise trend: the weight range of zetajet glass fiber nonwovens developed by German textilgruppe Hof company that can be used to produce automotive sound-absorbing panels is 18 g/m2 ~ 350 g/m2. 1. Box type and box type packaging adopt box type and box type packaging. When selecting the barcode position, Consider the different effects on the bar code symbol when the packaging is tiled and folded, so as to avoid covering a part of the bar code symbol after the packaging box is folded, or the left and right blank areas are insufficient; The bar code symbol printed on the carton should be printed on the side that is not easy to wear during the speed transmission of the modified Electromechanical, preferably on the bottom of the carton, and try to avoid being printed in the center; When the package is rectangular, the bar code symbol should be printed in the center of the bottom of the box. 2. Canned and bottled

for canned and bottled goods, if the bar code symbol is printed on the bottom of cans, glass bottles and plastic containers, it may increase the cost. The better way is to print the bar code under the side of the label

in bottled goods, especially polyester bottle like drinks, the packaging shape is uneven. After the label is pasted on the bottle, the bar code symbol also becomes uneven with the bottle shape, and wrinkles occur, resulting in the bar code symbol can not be read. In this case, the part of the label should be smooth when printing bar code symbols

stick bar code symbols on curved goods such as bottles and cans, and pay attention to the use standard of bar code: the surface curvature of the symbol shall not exceed 30 °. On the commodity packaging with curved surface, the selection of bar code magnification factor is related to the diameter of the curved surface. When the diameter of the commodity package is too small, if the bar code symbol is placed perpendicular to the bottom of the package in the direction of the bar code, it will be difficult for the scanner to scan it completely. At this time, the bar code should be turned 90 ° and placed perpendicular to the bus of the cylindrical package in the direction of the bar code

3. Barrel packaging

when the goods are plastic or paper barrel packaging, if the barcode is printed on the bottom, it needs special printing, which will increase the cost, so it is usually printed on the side of the barrel. If it cannot be printed on the side, the barcode can be printed on the cover, but the depth of the cover shall not exceed 12mm. If the container is filled with liquid that is easy to leak, and the container cannot be inverted during scanning, the barcode shall not be printed on the cover

4. Bag packaging

for bagged goods, if the bar code symbol is printed close to the edge of the bag, although it is inspected to be qualified after printing, it is easy to deform and fold after loading the contents, and it is still difficult to read the bar code correctly. The correct method is to avoid seams and deformed parts when selecting the position of the bar code. It is best to put the contents in the bag first, observe and find the flat part, and then print the bar code at this position

generally speaking, for bagged food such as bread and candy, when the bottom is large enough, the barcode should be printed on the bottom, otherwise it can be printed in the center below the back

for large bag packaged goods, the barcode is printed on the lower right side of the back, but it should not be printed too low to prevent the barcode symbol from being distorted due to the seam or wrinkle of the bag. For small plastic bags or paper goods without a bottom, the barcode should be printed in the center below the back. If there is a seam in the center of the back, it is printed on the lower right, or on the place where there is no wrinkle after filling

5. Blister packaging

for blister packaged goods that are not printed on the surface of the packaging card, it is best to print the barcode on the front of the cardboard, and the height of the protruding package shall not exceed 12mm, otherwise it will affect reading

if the height of the protruding package is 12mm higher than the cardboard surface due to the large volume of the product, the bar code should be placed as far away from the protruding package as possible, so that when the goods are read obliquely, the bar code on the card is within 12mm from the scanning window, otherwise it is difficult to read

in addition, in order to prevent the reading from being affected by the folding, deformation and damage of the package, when selecting the position of the bar code of goods, the blank area of the bar code symbol and the manually readable numbers should be at least 5mm away from the ridge, folding, overlapping and light cover. The barcode of the outer package of goods cannot be displayed at the same time as the barcode of a single retail commodity inside
