Beer trademark printing and precautions (on)

In 2004, the production and sales volume of beer in China reached 29.1 million tons, and the output has risen to the top in the world, and the production and sales volume is still growing. With the continuous increase of beer production, the demand for its packaging, especially trademark labels (including high, medium and low grades), is also steadily increasing.

Because beer needs to be refrigerated before drinking, it needs to be stored in the freezer often, especially in some areas in the south, it needs to be soaked in water for a long time. In addition, beer trademarks also need to bring consumers a strong visual impact and thus enhance the customer's desire to buy, so the design and printing of beer trademarks, compared to other packaging, there are many different. First of all, it has its own characteristics in the selection of printing materials for wine labels. Under normal circumstances, the printing of ordinary wine labels requires the selection of single-sided coated paper, in particular, the surface smoothness is high, so that the ink layer is even and thick when printed on the label; Towards the south, the beer must be printed on waterproof paper to improve the water resistance of the surface. Second, for printing inks, inks with high adhesion strength should be selected to ensure high-speed transport of the bottles on the chain during beer production. When there is no fading phenomenon, there is still a need to pay attention to the content of the layout in a simple and neat manner, so as to reduce the difficulty of printing and ensure that the printed products give consumers a strong visual impact. At present, China's beer trademark printing methods are mainly offset printing, gravure printing, and flexo printing. The following sections discuss their advantages and disadvantages and precautions.

First, offset printing

Offset printing is a relatively mature printing method. It has the advantages of high register accuracy. Therefore, some products of the beer trademark with low yield and high registration accuracy are generally used in this printing method. But when printing, you need to pay attention to:

1. Graphic design

Consumers' recognition of a product first passes a trademark. This requires the trademark to have a bright color to achieve a compelling feeling. Therefore, when designing a beer trademark, it should try to choose a color with strong visual impact. The content design of the trademark should focus on the field, lines, and text as much as possible, and strive to be concise and clear, reduce or reject too detailed overprinting, overprinting, trapping technology should also be considered in the production, so as to avoid appearing in the printing Direct deduction, in order to improve product quality and pass rate. In addition, due to the humidity of the production environment of beer, and the transverse deformation of the paper filament is greater than the longitudinal deformation, the plate making should be carried out in the correct plate making manner to ensure that the beer mark's left and right direction is in line with the paper's paper filament direction, so that the trademark can be Firmly affixed to the surface of the beer bottle, so that the labeling mark loss is effectively controlled.

2. Selection of printed materials

Due to the high printing requirements for trademarks, the following factors should be taken into full consideration for the selection of paper and other consumables. First, consider choosing a single-sided coated paper with high surface smoothness to ensure the color of the trademark is stable and bright. Secondly, the paper's permeable time should be considered. Since the beer labeling generally uses water-soluble adhesives, the speed of the beer production line is as high as 30,000 to 40,000 bottles/h. The trademark has just been affixed to the beer bottle and will result in beer bottles. Collisions, so that some trademarks with a short duration of penetration, are prone to breakage. Therefore, we need to observe the labeling of beer to find out the time it takes to mark the label after labeling, and use this as a reference to select the paper. In addition, the paper is to be printed by offset printing, and the printing principle of offset printing is ink-water balance, which causes inconsistencies in the performance of the paper before and after printing. Therefore, when checking the water-permeation time of paper, it is also necessary to consider the water permeability of the paper in terms of printing. influences. In addition, the paper's whiteness, opacity, and mechanical strength should all be given full attention when the trademark is printed. Only the high whiteness and opacity of the paper can guarantee the bright and uniform color of the trademark. Only good mechanical strength can ensure that the paper does not tear at high speed.

The selection of the ink should ensure that it has a high adhesion, and in addition, the inks selected for trademark printing, especially for beer trademark printing, should also have a lightfastness to ensure that the beer trademark is bright and durable.

3. The layout of the printing process

High registration accuracy is a major advantage of offset printing, but because offset printing adopts the printing principle of ink-water balance, the influence of overprinting caused by water-absorbing deformation of paper during printing should be taken into consideration in the arrangement of color sequence, and sometimes it can also be used. The deformation caused by the absorption of paper to the targeted arrangement of the color sequence to ensure the accuracy of the overprint. In addition, when printing, it is also necessary to ensure that the temperature and humidity of the printing environment are constant. Generally, the temperature is controlled at about 25°C, and the humidity should be higher than 55%.

When printing vacuum aluminum-plated paper, it is necessary to pay attention to the drying of the ink, and in particular to control the ink-water balance to ensure consistency of the ink color.
