The application field of the thermal transfer ribbon and the principle of work

Thermal transfer OLIVETTI printer ribbon  s a very wide range of uses, the amount is very huge products. With the development of information technology in China and rapid development of computer application domain unceasing expansion and in-depth, people of high speed, high quality output print demand more and more, and the traditional way of printing market in terms of price, printing quality, printing speed is difficult to meet the user needs in all directions. Thermal transfer ribbon made of high strength thin films due to the high concentration and ink, and the use of single use mode, so the characters of high quality printing, epson printer ribbon dfx8000/5000 and long service life, but also overcome the ink feathering, easily soluble in water and other defects, thermal transfer printing method to print medium without any requirements, can be in plain paper, recycled paper, waxed paper, ordinary film, envelopes, paper label until the cloth to achieve high clear print.
Thermal transfer imaging method was invented by Mille in 1953, along with the development of microelectronic technology, lithography technology, the semiconductor electric heating element technology and laser technology, especially the development of high sensitivity thermal transfer imaging function of material technology, thermal transfer printer as a non-contact printing computer peripherals hard output devices, has become a market share special kind of printer of high rate. The imaging principle of thermodynamics is heat transfer to the imaging material support body through computer signals to drive the semiconductor electrothermal head or laser, the imaging material heat melting and transferred to the text and image by image forming medium. Thermal transfer imaging material is coated on the base tape, called thermal transfer ribbon or thermal transfer ribbon.

Thermal transfer ribbon profile, and basic structure

Thermal transfer ribbon called hot foil stamping ribbon, referred to as the ribbon, English is Thermal Transfer Ribbon.
Thermal printing ribbon is printer supplies, is on the side of a base coated with wax, resin or mixed ink polyester or other high density film. In the absence of ink coated on one side with a lubricant to epson printer ribbon DFX9000 prevent wear and damage to the print head, a common shaft core ribbon with paper and plastic two, the main requirement is not deformation and not in print slide. Common ribbon with wax, wax tree based mixed base, resin based several. China, use of the ribbon are common date code Tandai, infusion bag ribbon, washing cloth, special resin ribbon cable with ribbon, barcode ribbon, wax - ribbon, mixed base - ribbon, ribbon and other kinds of resin matrix - type. Different materials and varieties of Nylon ribbon roll   ribbon for printing materials and printers have different applicable in thermal transfer ribbon, ribbon / technology, printer performance is the primary.
A) thin but strong polyester or other high density material with base;
B) bottom coating with matrix positive to ensure that the ink evenly and printing ink transfer complete;
C) ink layer of wax or resin base;
D) outer coating layer on the printing ink in ink and enhanced protection and adhesion of printed material;
E) back coating base with anti-static, both heat and reduce friction, in order to protect the print head.

The working principle of inkjet printer

Head of technology is the key technology of inkjet printer ink, the ink head type has been from the traditional bubble of hot gas and micro piezoelectric technology dominated. Hot bubble print technology application earlier, mature technology, low equipment cost. But because of the ink cartridge with ink to create pressure under the action of a hot bubble, so the cartridge must become integrated with nozzle structure, so the material are relatively expensive. And because the ink head to work for a long time in high temperature and high pressure environment, nozzle corrosion is serious, also easy to cause drops splash and nozzle blockage. Application of hot gas bubble method of printing color inkjet printers, Canon and HP company's main brand. At present, the total thermal inkjet print head of nozzle can reach hundreds, even thousands, of each nozzle diameter with hair, spit out the OLIVETTI printer ribbon PR3 minimum of 4 drops capacity rose slightly. Three color is green, magenta and yellow ink head is often one of the water, will be a few small colored drops combination, can form different sizes of ink, to produce more abundant harmonic color and smooth halftone. Black ink ink head are separate.
Piezoelectric method with ink dot shape rules, no splash, ink dot size can be controlled, can choose more different chemical epson printer ribbon LQ310
  composition of the ink, the opportunity to reduce corrosion, the advantages of the nozzle life extension. Users can also use powder ink and oily ink, so as to prevent discoloration caused by ultraviolet light and faded. Due to less pressure in micro piezo ink head, nozzle is, in fact, has been replaced by a piezoelectric ceramic chip, is no contact between the nozzle and the cartridge, so head in micro piezoelectric ink and ink cartridges are discrete structure of nozzle, such a nozzle can support multiple ink cartridge, thereby greatly saving the cost of the use of the user. Micro piezoelectric inkjet technology is Epson company's patent technology, the mainstream of latest Epson inkjet printer head. There are 128 black ink nozzle, color ink there are 288 nozzle head (96) of each color, natural resolution of 1440 dpi x 720 dpi. Epson designed for piezoelectric technology development of the ink is very exquisite, has dissolved and quick-drying properties, can rapid permeate into the paper, no flash, no dizzy catch, print quality is very good, especially in the inkjet paper and glossy paper.

Printing two (non-contact printing)

Non-contact printing is printing, any part of the printer is not contact surface are printed. The main method has the ink jet and laser printing type two kinds. Contact print compared with non-contact printing, people attach more importance to the latter. This is because the non-contact epson printer ribbon printing, can be in operating condition changes under the condition of wide application; And on a variety of different materials, can print out the clear writing and design in a reliable way.
1. The ink jet printing method
This method is to put the tiny point from one or more ink spray printing head through the slot injection into a production line of each package, the form of lattice's handwriting. The handwriting height is from a few millimeters to more than 50 mm.
Use a microprocessor control program of the letters and Numbers, number equals the number of spray printing head. At the same time, through the role of the sensor and the speed of production line, to ensure that each package can correctly printed on code (with words and Numbers compatible olivetti printer ribbon represent data).
Ink jet is accomplished by pressure or electrostatic. This method USES the printer there are many kinds of models. Can along the horizontal direction from bottom to top, from top to bottom; Print or from any Angle. In the two kinds of non-contact printers, ink jet printer used more widely.
2. Laser printing method
By the laser beam transmission system, optical imaging system and sensor of synchronous positioning system. In optical imaging system, in addition to the reflector and transmitting mirror, there is an engraved with the printout template. The laser beam through the gap on the template and the image on the surface of the focusing lens in the packaging. Instantaneous high-energy from laser beam, in the microscopic thin layer on the surface of the packaging printing work according to the shape of the image.
The role of laser energy produced in the package, depends on the composition of surface; On the coated metal and paper, is the coating material (such as ink, paint and spray paint, etc) to burn to a layer to form the handwriting; In some plastic or ceramic surface, the result of shows like heating effect of color pigment handwriting; On the glass, and some other plastic function, the result like frost or etching effect of handwriting.
Different plastics have different reactions to the laser energy. Some plastic only absorb all or part of the wavelengths of light in the laser does not absorb.
In acetate, cellophane, polyester, vinyl resin, polycarbonate, polystyrene, polyvinyl chloride, such as material, use laser printing can get very good effect.
Laser for polypropylene and polyethylene film doesn't work. This feature is also useful. Can be used in the film wrapped package paper to print. This is to use other printing methods do. Aseptic packaging of fruit juice and other drinks, for example, after filling outside with plastic film wrapping package for laser doesn't work, preserved in cold storage or wholesale stores in the freezer. When sold to retail stores to sell date print. It can not print during production, and with a laser at the beginning of the sales through the plastic film on the aluminum foil or paper to print the date code.
The main advantage of the laser printing is printing the handwriting will not be dirty, alter or wipe away. Defect is the printer price is expensive, so that its application is restricted. Only commonly used for mass production, or use other printing methods can't print.
About the standard of trademark, packing marks and codes, regulations, rules, some have been issued and implemented, some is in the formulation, will be published and constantly improve, this part name as follows:
Dangerous goods packaging symbol GB190-85.
GB191-85 packaging graphic symbol.
GB388-86 transport packing shipping marks.

Printing method

1. Wet printing
Is wet printing ink or paint, oil or other solvent modulation, the fluid status, subject to a certain time to dry after printing. So, referred to as the wet printing.
Oil when wet printing ink from printing components (such as seals, plate and printing roller, etc.) in direct printed on the surface of the package, called direct printing; From printing ink components to a first surface soft transfer printing roller, and then from the transfer printing roller printing on the package, called a transfer.
No matter from the process or equipment, wet printing is a kind of early use of cheaper printing method. Wet printing ink needs to maintain the specified viscosity, easy to spill or leak when using, often need to scrub. To this end, the wet seal the intensity of labor is higher than other printing methods. In addition, the text of wet printing are easy to be dirty, so need a certain amount of drying time, this will impede the flow of products in the workshop. Choose the appropriate ink, is the key to the wet printing. This should be a quick-drying ink, and can be reliably adhesion on the surface of package.
2. Hot stamping
Will need to print the data with hot melt ink printed on advance TTR printer ribbon  ubstrate made of metal foil, the handwriting is reverse. When printing the substrate printed with the words of one side were applied in packaging materials on the surface, and then heating melt ink, the handwriting is printed on the package. Print out clear, will not be blotted out, and the quickly dry solid. This method is best suited to the occasion of printing results for clean and beautiful. Heat is printed and the general humidity ratio of expensive price, and need some time to stop with substrate reels, therefore, printing cost is higher.
3. The dry seal
Use a hot melt plastic roller, heating the activation and for printing ink, print out the handwriting immediately dry solid. Print can realize high speed operation, under the speed of print 1000 beats per minute, can work continuously and high print quality. Can print on the IBM printer ribbon commonly used all kinds of packaging materials, printing ink consumption is slow, such as printing size of 3 x 25 mm, but do not need to print 250000 times in a row in the printing roller, thereby greatly reducing the downtime. Although this method of printing is emerging, but have been developed to combination can be easily used packaging production line.

Printing technology printed (contact)

On printing refers to the goods or packaging are printed on a variety of constantly changing information. Such as product production date, batch number, code, logo, product freshness, validity and price, composition, color, weight, size, etc. The content for commodity warehousing, transportation, sales and consumers to purchase is very important, and often STAR printer ribbon should change. , therefore, not when printing packing bag, packing and label printing, print out a blank sash only when necessary, after packaging for printing.
Early printing method, is done by hand. Commonly used is the pragraphs plate (on galvanized steel or waxed paper thin, such as the need to print words and figures carved hole), ink or paint brush with the brush on the container; Also can use spray gun spray printing; Sometimes used rubber carved into a seal for printing.
With the need of modern Epson printer ribbon dfx8000/5000 production, there appeared a lot of semi-automatic and fully automatic printer. Can be divided into two kinds: one kind is contact printer; Another kind is contact the printer.
Contact print is dip in with ink printing element direct contact with the packaging material or container surface printing. Including wet printing, hot stamping and dry three methods. The wet printing and direct printing and transfer printing two.
