Adhesive labels, as an important component of commodity packaging, with advertising, commodity instructions and other roles, is an important way to identify goods, identify the efficacy of goods, in reflecting product quality, causing consumers to buy plays an important role, different varieties of raw materials, different uses of the label, the processing technology used is different.
General label printing machine for multi-purpose machines and equipment, manufacturers can develop printing production process according to the needs. Self-adhesive label printing production and processing production process is shown below.
(1) Feeding
A intermittent: the roll of paper is released without tension shift, so no adjustment. Utilized in the flat, round flat labeling machine, the release speed is relatively slow. Because these machines and equipment without printing paper precision positioning calibration equipment, the provisions of the roll paper bore clean and neat, to ensure accurate printing when printing.
B rotary type: used in the wheel transformation round press round label machine. Because when the roll paper diameter rate shift, the paper has tension shift, so this equipment has tension fully automatic or manual adjustment mechanism, also has the roll paper correction device calibration equipment, in order to ensure stable paper delivery, to ensure printing quality.
2）Stamping
Flat press: used in round press, flat press label machine, low rate.
Round press: used in the round press round label press, faster speed, can be sustained foil stamping word, generally very little application, widely used in the printing gold processing process instead of foil stamping.
3）Printing
Flat press: suitable for small areas, simple pattern printing, such as labels, bar codes, etc.
Round press flat: suitable for containing field, general pattern of label printing, can achieve a simple colorful eye tone printing.
Round press round: suitable for a variety of patterns label printing, especially in the appropriate high-grade color eye-tone label printing.
UV printing: in the above three printing methods, coupled with UV dry mania, can be printed film self-adhesive materials.
(4) first foil stamping, then printing
On the facility without UV drying, the application of general ink, the defect is the printing design pattern is limited.
5）Printing first, then foil stamping
Utilized on facilities with UV drying device, the ink dries quickly after stamping on the ink, stamping pattern design scheme at will, will not be limited by the ink, applicable to high-grade label printing, is a modern production process.
6) Varnishing
Field varnish: in the ink surface layer coated with a layer of varnish oil, the purpose is to maintain the ink layer, waterproof, moisture and its enhanced surface gloss, can replace the film processing process, the choice of UV dry manure method.
7）Lamination
In the paper or film on the raw material lamination, the purpose is to maintain the ink, moisture, waterproof, enhance the strength of the label, enhance the pattern of the hierarchy. Film into a backing paper lamination and no backing paper lamination, because the latter is a low-cost, widely used at this stage. According to the standard of processing technology, there are two kinds of composite transparent film and matte film, the former one is more widely used.
8) Perforation
Not widely used, the key applies to the electronic computer printing label. Provisions are made on both sides of the label to play precise positioning to promote the hole, or pricing gun on the use of the label, the provisions in the middle of the label to open the hole for precise positioning and promote the use.
9）Die-cutting
Self-adhesive label die-cutting for the semi-cut through processing technology, that is, only cut through the surface layer of raw materials and save the bottom paper. Divided into two types of production and processing methods.
Such as flat die-cutting, suitable for a variety of label printing machine, human printing plate, low cost, short printing plate cycle time, but low viscosity, suitable for short-run live printing production and processing. At this stage, Chinese label factories basically all choose flat die-cutting methods.
In addition, a kind of round die-cutting, the use of round label machinery and equipment, faster, high viscosity die-cutting, suitable for long version of the work, the defect is that the printing plate cost, long time. At this stage, Chinese manufacturers of die-cutting rollers are generally produced and processed overseas.
10）Receiving
It can be roughly divided into cut sheet and folded sheet.
