Description
Technical field
The invention belongs to information technology and field of anti-counterfeit technology, and in particular to a kind of gold stamping RFID and its preparation
Method.
Background technology
1. electronic label technology
Electronic tag is RFID (Radio Frequency IDentification) technology, and electronic tag is also known as radio frequency mark
Label, transponder, data medium, also known as radio frequency identification, it is a kind of communication technology, is a kind of wireless communication technology, Ke Yitong
Cross radio signals identification specific objective and read and write related data.The basic module of its system includes RFID, RFID
Read write line and antenna, wherein, antenna is a kind of with RF signal power reception of the electromagnetic wave wireless set or spoke
The device being shot out.RFID operation principles：After label enters magnetic field, the radiofrequency signal that plug-in reader is sent is received, by induced electricity
The obtained energy of stream sends out the product information of storage in the chips；After plug-in reader reads information and decoded, central letter is delivered to
Breath system carries out relevant data processing.
While enterprise constantly seeks to change with innovation under new normality, new technology emerges in an endless stream with new industry situation, intelligent
All become more " wisdom " with quick popularization and application in logistics, all core links in enterprise's production with informationization technology.Industry
4.0th, Chinese intelligence make, internet+... one gushes.How using technology of Internet of things the production of wisdom and logistics management made
System, realize wisdom production and can the logical whole world of thing, the dosage of electronic tag is also increasing under this overall situation, printing,
The market share occupied by the fields such as wisdom packaging, manufacturing technology is also more and more, the also more and more higher of the requirement to electronic tag.
New breakthrough is needed at the false proof aspect of electronic tag.
2. gilding technology
Gold stamping is exactly by certain pressure and temperature, with the template on thermoprinting machine, makes printed matter and printing plate
Press in a short time, metal foil or color pigment paper tinsel are transferred to by the picture and text requirement of thermoprint template and added by the surface of boiling hot material
Work technique.This technology is increase label, trade mark, tobacco and wine packaging and various high-grade packing box visual effects and the important work of class
Skill.
First ironing and then printing can be divided into from technique and first printed and scalded afterwards, first ironing and then printing is electric in first thermoprint on blank carrier
Change aluminium foil layer, then in aluminium foil layer surface printing picture and text, be used for needing the package printed matter of large area thermoprint, and first print and scald afterwards, be
On printed printed matter, the pattern that is needed in the position thermoprint for needing thermoprint is a kind of work being widely used at present
Skill.
From thermoprint mode, it can be divided into hot stamping technology and cold-hot stamping technology again.Hot stamping technology is exactly mentioned above
Need certain temperature and pressure could complete the hot stamping process of phone aluminium foil transfer.Cold-hot stamping technique is by by UV adhesive
Being coated on printed matter needs the position of thermoprint, the technique that electrochemical aluminum foil is transferred into package printed matter surface through certain pressure.
Both approaches respectively have feature, meet the needs of different product.
With the rapid development of stamping systems and packaging industry, electrochemical aluminium gold-stamped application is more and more extensive.Such as：Book cover
Gold stamping, gift box is gold stamping, cigarette, wine, gold stamping, greeting card, invitation card, gold stamping etc., its color and the flower of pen of the trade mark of clothes and box
As many as line, can also be according to specific requirement special edition customized.More preferable effect can be reached by being used in combination with electronic tag, widen application
Scope, and keep up with the paces of big data Internet of Things.
