Beer Label Gravure how to meet the labeling requirements - label printing, gravure - printing industry

China Suppliers


Present, Beer Label They use a 65? 80g/m2 one side of Coated Paper , Wet strength paper, sprayed aluminum paper, Print Way Offset printing , Gravure , Label of quality and Label Of Fiber Direction, roughness, moisture content, dimensional stability, curl and time factors. Specific requirement is that the direction of paper fibers Bottle Axis vertical; water content of about 5% to 7%; in the humidity of 40% to 80% of the conditions, the leaflet label formation; positive and negative curl height of not more than 3mm; back curled into contact with water, the time tubular should be more than 8 seconds. In addition to these factors, the print quality to meet the standard requirements liquor, or will it difficult to label.





Beer label labeling in the prone and causes of quality problems
solar stepping stones


1. Gluing uneven (up and down both sides with adhesive, no glue or the middle of the middle left and right sides are plastic and rubber). The main reason is beer label paper, not smooth, positive, anti-curl highly than 3mm.

2. Take the time marked out sheets. Beer label paper mainly positive curl height greater than 3mm, the labeling process between the bid and the standard air can not enter, get a double-standard when label sheets or more.





3. Tags pleated or Qiaojiao (paste bottles good, but in the transmission process of labeling the four corners tilt). Mainly due to low moisture content of the label paper, with water fast elongation.





Present, most Printing Technical level to meet the appearance requirements beer labels, beer labels how to control the internal quality processes to meet the labeling requirements is key. From the above analysis, the cause of beer labels curl, Qiaojiao mainly due to issues such as beer, the lower the moisture content of the label paper. If the printing and After India Processed in different ways, but also by controlling the beer label paper to control the printing of water quality changes.





Beer label paper printing in different changes in water content


1. Offset label leaflets, single or multiple overlay to complete the printing, Ink Conjunctiva dry, natural cure, as offset printing ink exists in balance, so the water content of paper and print labels moisture content consistent.





2. Gravure label is pre-dried by the web, continuous multi-color overlay. Winding completed in each color ink by drying and after Solvent Volatile and dry, the label will cause repeated water loss after drying. Elongation from the paper wet, drying shrinkage can see, offset printing paper labels are in the "stretch" the case of printing, and gravure paper label is "shrink" the case of printing. Therefore, if the Beer Label Gravure process when the master of all good, finished affected by humidity, curl occurs, resulting in labeling failure. How to solve the water content of gravure printing beer label change, to adapt to bottle labeling requirements? May wish to note the following. Note





Beer Label Gravure 1. Back Wet: print label after the completion of restoration of the water content;





2. Shape: According to the performance of different paper wet in the process of adjusting back up water;





3. Formation: web cutting should be done after the product leaflet formation processing;





4. Workshop to keep the air humidity.
