With the rapid industrial development and raise the level of product quality, many industrial products, such as instant noodles, snack foods, cosmetics, liquor, beverage and other packaging materials to be printed on the surface of the production date and shelf life, and some need to print product identification bar code and security signs. Extensive use of computers and printing standards, need to instruments (such as bus tickets, train tickets, tickets, etc.) and many files quickly print out some of these rely on thermal transfer ribbons in the corresponding printer (or coding machine) to complete.
sublimation ink ribbon used in current solvent-based and wax-type two categories: the former is the type of ink preparation materials are more costly, the need for ribbon preparation and drying processes exist to varying degrees, resulting in solvent evaporation environmental pollution problems; which basically does not have this problem. This article provides a wide range of sources of raw materials, quality and cheap ink and ribbon wax preparation method.

2 Results and discussion
2.1 the choice of sublimation ink formulations
Sublimation ink is a new type of ink, it is very different from ordinary ink. Because the first sublimation ink attached to the baseband, when used through the heat to transfer ink to the desired part of the surface to be printed, while the ordinary ink is printed at once, so the ink quality is very different large. For example: ordinary ink hope the bigger the better adhesion, and sublimation ink adhesion to moderate, too large to complete the transfer process, too easy to de-inking Ribbon (waste), poor adhesion after the transfer ribbon. In writing clarity, temperature and other aspects of the thermal transfer printing ink has its own specific requirements. Therefore, an ideal screening sublimation ink formulation is not easy, for each component of the specific performance requirements are very strict. For example, vinyl chloride – vinyl acetate copolymer resins are many varieties, the proportion of degree of polymerization and monomer polymerization great impact on product performance, so the choice of raw materials for the formulation and accuracy of dosage need to continue to explore the practical application.
2.2 improve the sublimation ink in the heated state of permeability is essential
In the thermal transfer ribbon and the process of preparation, sublimation ink are in a molten state, the sublimation ink adhesion play a role mainly by the resin, thermoplastic resin so the resin must be used, the author developed the modified polyvinyl acetate good application effect. Polarity of the high melting point of stearic acid and rosin to the ink permeability play a significant role, experiments show that the amount of this polar material added, to improve adhesion and thermal transfer resistance after writing a very clean performance good. Meanwhile, the role of surfactant stearic acid and rosin fully dispersed pigment also played an active role.
2.3 the choice of colorants
Colorants may be dyes, pigments can also be generally used in sublimation ink pigment more. When using pigments as coloring agents, be carried out if the paint is ideal for micro-encapsulation process.
To make bright and beautiful color effect can also use 2 or more color pigments or dyes. Commonly used carbon black pigment or dye, iron black, iron blue, iron red, phthalocyanine blue, phthalocyanine green, Fast Red 2B, Fast Red 7B, Lithol red, magenta 6B, benzidine yellow 2C, John solid yellow GT, titanium dioxide.
2.4 heating temperature control
In the production of ink, should control the heating temperature, the temperature is too high will cause coking and decomposition of some resin, and even fire accident occurs! In principle to meet the melting temperature is appropriate, and to keep stirring to prevent local overheating.
The coating should also control the proper temperature, the ink temperature is too high will cause the ink ribbon base-band distortion and loss, the temperature is too low when the ink into a semi-solid (or solid), can not be achieved coating process.
P> In the thermal transfer, the same printer to regulate (or machine) prefix temperature, which is essential for printing.
3 Conclusion
Sublimation ink and ribbon consumables as a new high-end market has great prospects. Because of its preparation and use of the special nature and the disciplines involved in cross-cutting edge, there are no standards, many areas need intensive study and research.

1 Effect of sublimation ink Summer

Sublimation ink effects occur in summer temperatures after the fundamental reason is that some of the changes caused by sublimation ink. Mainly by the pigment printing with sublimation ink binder, in addition, there are some fillers and additional material. For newsprint, black mineral oil used for sublimation ink binder, colored sublimation ink is used vegetable oil as binder.

Black Sublimation ink printed on paper, the sublimation ink in the binder (mineral oil) in the beginning of the paper’s surface, but after a period of time (4-6 months) of age, almost all of mineral oil absorbed by the paper, because of its poor ability to absorb oxygen, leaving the binder on paper, very little cross-linking, and no rigid structure, and only some weak and fragile structures, so the formation of many small sublimation ink particles.

Vegetable oil sublimation ink printed on paper, the sublimation ink in the bonding material (vegetable oil) are also in the beginning of the paper surface, but because it ability to absorb oxygen, after a period of aging, vegetable oil is part of the paper absorbed, but many still remain on paper and pigments bonded together. As the unsaturated vegetable oils have double-stranded structure, it can form a number of cross-linked rigid structures, and attached to the fiber.

Vegetable oil, mineral oil sublimation ink and sublimation ink printing solution of old newspapers in the broken machine broken solution, the mineral oil than vegetable oil ink sublimation sublimation ink is easier to fragmentation, so fragmentation ERIC value after the High (effective concentration of residual sublimation ink particles) and fully washed, and then paste in the irreversible deposition of sublimation ink particle concentration is also large, this waste pulp brightness greater impact.

(2) effects of sublimation ink whiteness affect summer

Canada deinking pulp brightness minimum 6-8 months each year. North American whiteness Deinking July and August each year a minimum, about 1.4 lower than normal. White paper pulp factory off July and August each year degree is the minimum. Such as: 98 degrees minimum pass rate of 46.2% white, 99 years minimum passing rate of 71.2% whiteness, whiteness of the lowest pass in 2000 was 2.6% in 2001, the lowest pass rate of 11.3% whiteness. Thus, no matter which country or region, the sublimation ink waste paper deinking effect is common in summer.

Currently, many dye sublimation inks on the inaccurate information filled website and forum, so unknown to novice, to be deceived. The author combines his many years of experience, sum up the history and sublimation ink China market information, to set the record straight.

Sublimation Ink (also known as sublimation ink) is the low-energy, easy to disperse dye sublimation digital printing ink produced, printed on transfer paper, by heating, in the shortest possible time, the image produced to fine porcelain , metal, silk, chemical fiber fabrics and other materials, is very suitable for the development of individual market needs and environmental requirements.

Sublimation inks are mostly used by the textile disperse dyes prepared. Disperse due to its saturated color and good weather resistance, so in the textile dyeing and printing has a wide range of applications, so far still printing and dyeing industry, one of the main raw material. The traditional textile printing and dyeing industry use dispersed pigment dyeing process has serious environmental pollution problems, and are not suitable for small batch production. Also in the screen printing of disperse dye ink has a certain market in the world have done a better quality of LECHLER SPA of Italy produced a series of sublimation ink screen printing, the company currently has sales offices in Shanghai, its products of good quality, but not cheap.

The first generation of digital sawgrass sublimation ink by the United States developed in the late nineties and in patent, trademark its products Sublijet ®, Epson and other major for piezoelectric printers. Subsequently Dupont, BASF, Sensient, Ciba and other companies are aware of the tremendous business opportunities to the product, and soon launch similar products. Before 2001, due to nano-technology is not mature, companies have the problem of quality ink, so the heat transfer technology and related products has not been quickly developed. Dramatically, ASF 2002, the company in order to ensure that their dye-sublimation ink industry leading position in the acquisition of Sawgrass fail, through sawgrass court of the United States patent is invalid, Sawgrass responding to two near the end of bankruptcy, but in the end won the case. Sawgrass followed by patent protection in the U.S. market monopoly sublimation ink sales. At the same time Dupont, BASF, Ciba, Sensient and other companies can only pay royalties and sawgrass in the manner authorized to sell, and slowly fade sublimation ink market. Because sawgrass with patent monopolies, leading U.S. and European markets the high cost of dye-sublimation inks. As the ink from the Korean patent restrictions, the price is relatively cheap.

Heat to get good results, you need the machine, software, transfer paper, ink, transfer conditions and transfer the combined effect of the material. In this regard, the United States sawgrass is put up R & D to develop products of the company. With its supporting image transfer products and processes can achieve professional-class, but because their prices expensive, so currently only sold in the U.S. and European markets (market price around 200-300USD / liter). If only to compare the quality of ink, Sawgrass ink is the most stable, which can reach 2-year warranty requirements. Lechler SPA’s ink only about 6 months to 1 year warranty, if you spend expired ink, it may be a problem. South Korea ink reduction of color have some problems, but overall quality is still better than the homemade ink, do not plug the basic phenomenon.
Currently popular in China mainly imports sublimation ink company in South Korea and Italy Lechler SPA INKTEC the Manoukian-Argon dye-sublimation inks. From the price, the Korean ink is cheaper, should be in the 400-600RMB / liter, Italy ink is more expensive, but quality is better guaranteed. Many brokers claim to original U.S. sales of ink, they are actually false advertising. Because there is no ink in U.S. sales in China. South Korea INKTEC company to the wholesale price of Chinese agents about 250-300RMB / liter. So if you buy less than 300RMN / liter of imported sublimation inks, basically is a fake.

Sublimation ink is applied trend of industrialization and wide. But this demands a higher ink. At present, the dye-sublimation printing market is mainly small amount of the desktop application, but in Europe, especially in recent years, dye-sublimation inks have been applied to industrial production, so the heat transfer market has developed rapidly, to 30% per year growth rate.
