HC screen Special printing network Real wax print technology is introduced into our country in 1996. With our traditional hand batik completely different, real wax printed cloth all mechanized production, wax printing cloth is to natural rosin melted, reaching around 170 (temperature according to the proportion of new and old wax be) printed cloth double surface, and then dye main color, thrown wax pattern, alkaline cleaning wax pattern, then dyed a variety of colored lines. Well after the wax pattern, wax rope back wash at room temperature, left in the middle of the cloth and yarn rosin, caustic soda must be added after warming up multi-channel rope washing machine washing. To rosin saponification with caustic soda at high temperature and dissolved in water to wash cloth. This production process caused serious water pollution. Wash the batik cloth, in the back once again with the rotary parts of wax Printing machine Penetration Printing Can achieve double flowering. Penetration Printing Gray hair before treatment required to achieve the penetration effect of high efficiency, to achieve consistent double-sided color. Industry and Trade Co., Ltd. Qingdao Hexing

According to product requirements, developed a new alternative to rosin PDT Paint And double-sided multi-color rotary screen printing machine, create a new batik process.

1, PDT new paint (a wax method)

1.1PDT coating composition and use of

PDT main component is sodium silicate paint (commonly known as sodium silicate) as the main raw materials and various additives prepared from the use of the product is a colorless thick liquid 400Be.

Instead of rosin with PDT, in the double-sided printing machine to print designs, the design of space contracted main color.

Corrugated machine with a dedicated roll out the different styles of cracks. Horizontal and vertical thickness can be staggered, to dye a variety of colored lines. Use of PDT as paint can make hair wax pattern, Korea currently can not make hair with rosin is like wax pattern effect.

1.2 Process Printed PDT dye main color paint corrugated pattern dyeing joint width washing machine (return PDT) tenter double-sided multi-color printing paper fight. The production of new paint

1.3PDT Above it is clear that this process is short, the first printing PDT coating at room temperature, eliminating the need for rosin-based wax process, saving a lot of Energy . If the two conventional wax printing production line, to be equipped with 800 000 kcal oil boiler to meet the production needs, must also be used after printing rosin refrigerator, cold roll by more than just salt water cooling temperature drop cloth can be dry. PDT with double-sided color printing under the printing machine into the cloth, on a cloth by the infrared pre-reheat and air drying. Drop cloth can be dry.

1.4 dye main color process requirements

Dye main color dyeing machine using the best IBN. Because PDT coating easily dissolved in water, dry cloth dyeing, fixing the best dry cloth.

1.5 production hair-like color patterns

Printed color rosin can only make a rough pattern, hair wax pattern is not make to the. Printed PDT coating developed using our combined corrugated dyeing machine, you can crack one-time roll out thin. To make direct dyeing hair-like color pattern. After eliminating the Indian rope thrown rosin wax pattern, open rate, alkaline cleaning wax patterns and other processes.

1.6PDT paint washing and recycling

Today, the rapid development of digital printing technology, many new models are for spot color or registering color and configured, can greatly expand the application of on-demand color printing.

Printing giant Xerox has always been to release the latest digital printing technology is known, I still remember their digital printing press in October, was at the GraphExpo show scenes of people crowded around it? It really is surprising. National Association for Printing Leadership in 2006, industry report stated that: “Digital printing is creating an exciting one by a miracle.” The association found that in all the enterprises surveyed, 75% regarded the enterprise digital press as their main production: This press can produce a continuous variable data elements: the next few years this service will be one of the fastest growing areas did not.

PIA / GATF Digital Printing activities this year would grow 4.2%, and to 2006, called “digital print on.” When people realize the benefits of digital printing technology since the number of digital printing members of the Committee for a three-fold increase.

CEO MichaelMakin Digital Printing Council, said: “Most of our members are very interested in digital sound, and often carry out research on this technology, we have been closely watching its development trend.” In 2007 , digital printing infrastructure committee will make some adjustments, this way, all the members are from the new management model to benefit.

In general, color production quality and in this year’s exhibition on display are all digital presses that print quality to us is no longer an issue. Integrated workflow and between manufacturers Cooperation Relation to digital presses can also be found in the offset printing mill their own position. Equipment manufacturers are constantly strive to reduce product costs, such as xpedx to iGen3s and NexPresses launched high-speed presses PPC-style products JJ Bender.

The latest digital press The core of development of digital printing equipment and toner compatibility between the so-called “toner” is a digital printing ink. Toner yield significant growth has been reflected in the Toshiba toner manufacturing plant in Mitchell’s expansion, the company’s number of employees has tripled, plant area has expanded to more than double to 100,000 square feet . This year, Toshiba will invest 15 million U.S. dollars, increase the production capacity of color toner, but it also will become the only Japanese production in the United States OEM manufacturer of color toner.

All in all, toners for a traditional or chemical type, mainly to see its production. Plastic, colorants and additives mixed together and then put these materials into a fine powder which is the traditional method of making toner. It can also be made as needed to these powders of different sizes and shapes. The chemically produced toner particles is small, and relatively uniform.

IBM into the inkjet market IBM at Graph Expo, the company conducted IBMInfoprint color technology demonstration to show how we use inkjet printers in 20.4 inches wide web on the printing color double-page.

The Canon products through a named SuspensionPolymerization produce the S toner.
Koenig Card Minolta and Xerox’s EA toner SimitriHD use of the emulsion aggregation toner technology. Emulsion is an integrated chemical process, which enables the formation of toner resin emulsion, while the toner synthesis means to gather together the various components, made into the appropriate size (pre-designed good size) and shape (spherical ).

Manufacturers of digital presses, toner is also an ongoing source of income, regardless of whether they took their production of graphite or other brands of toner processing, these products are specifically designed for a specific printer of.

Xerox senior vice president of supply JohnLaing that his company and most other printer manufacturers will produce their own color printer on the use of traditional toner, and office / working group on the use of chemical toner printer. This change occurred early start. Laing said: “The size of the intersection of toner that is traditional and that can convert chemical toner size, probably 7 microns.”

He also pointed out that the dye is, there is a lot more important than the size parameter. The choice of pigment and its dispersion are critical. Pigment will affect the performance of toner, and it directly determines the efficiency of charging the print gloss.

Kodak NexPress presses also use their own traditional toner. In the next few months, the company will also launch a new type of light-fastness of the magenta ink. It will be available to all new and existing customers and will replace the magenta ink. Kodak will be in a particular day that this matter.

The chemical side, Konica Minolta’s new SimitriHD color toner is designed for the production printing market development, and will be the first application of the bizhub PROC6500 printer. The company says its small particle size provides smoother print out the order to reconcile the text more clearly. In addition, it leads to less toner use resulting in lower production costs.

Canon toner latest imagePress C7000VP is a pulverized toner, rather than chemical synthesis, this toner image quality better than the chemical toner. V-toner uses the average size of 5? Micron particles, because of its smaller toner particles, it can print out the image detail, and to improve the overall quality of the image. V-toner does not use fuser oil, but filled with wax (wax can help toner adhesion on the page). Clear hot melt oil helps to reduce the incidence of failure or the printed image. In addition, V-toner also achieves greater color gamut than offset presses.

Xeikon claims to be the first to polyester shaped toner used in the high-speed color printing process of the company. The company’s parent PunchGraphix believes that the new FA toner technology to chemical toner and the advantages of combining the traditional toner together. It is understood, FA toner is now certified by the FDA, can be directly used in food packaging.

CD Screen Print By Squeegee Pressure plate to ink scraping net transfer to the substrates (CD surface), thereby forming ink graphic process, supported by wire mesh body, so essential to the production screen.

1 rational choice Stretching Tension Screen Printing
important parameter is the wire mesh, mesh wire diameter, wire thickness, hole size, and under the ink, screen diameter, mesh and wire mesh weaving methods and materials directly chosen Stretching tension affect the size, stretching the basis of these parameters on the screen when the tension test. Measurement of tension, the tension point should be measured from the Network box Position within the frame 10cm, or measure the tension is not accurate. Tension can be divided into the warp and woof of the tension, stretching through to the tension is when the entire volume of the tension wire winding direction; screen is the screen width of the weft direction of the tension on the tension. Tension of the size of the screen has a direct impact on the quality. The network version of high tension network with a lower distance, the printing process to use less pressure, reduce screen wear, longer life, less pressure also helps to avoid network surrounding AIDS ink, deformation, increase network edge sharpness to ensure the printing effect. When the net increase of 1 times the distance of time, will increase by 3 times the deformation of the printing graphics. Screen tension is low, and under the ink dot gain uneven deformation affecting hue. Screen uneven tension will cause uneven ink film thickness, pattern distorted text, local graphic fuzzy, network printing, so that deformation or dislocation and other outlets, resulting in Hue. But all kinds of wire mesh can withstand the maximum tension values are different, if the value exceeds a set maximum tension, screen will lose elasticity, known as plastic deformation or nets, the stretching should be attention.

2 network box of the proper use of
Screen frame materials, section size, shape and processed formation and intensity of such a direct impact on screen tension and tension stability. Network box on the stick before using the network perimeter to surface and burr processing. Repeated use of the screen frame to use acetone Solvent Cleaning, remove the screen frame surface residual ink Glue And screen debris. Stretching before the box on the network side pre-coated layer of sticky adhesive mesh network glue stick in the wire-line network Reapply when a layer of plastic, pay attention to glue to penetrate into the fitting screen surface side of the net hole, so that Screen fully bonded in the network box. When necessary, the glue is not completely dry, with plastic lamination pressure surface scratch, to help screen completely affixed firmly network box.

3 Stretching Method (1) Standard Stretching Method Torn off before the end of the first screen irregularly, such as quantity within the folder into the chuck, and pave the screen, and then clip the other end through to the screen, and finally to network folder folder zonal boundary, this time mesh tension-free.

Requirements will be pulled by the tension of the net value of 1 / 2, and then stretched weft, so that the tension of tension close to the required value at the same time, then adjust the zonal and meridional tension, so that all the required tension value static 10min, to fully release the stress. 10min after the adjustment of the tension of warp and weft tension to meet the requirement, still around 10min, so repeat the operation twice, and then brush Sensitive adhesive , Will stick in the network box on screen, complete the stretching process. This method is a widely used standard stretching methods.

(2) 30 Stretching Method Warp and weft direction of the first to meet the requirements of half of the tension, stability, about 1 ~ 2min after netting, so that increased tension required value of 80% to 90%, stop 5min, and then netting to make it to the required tension values of the tension about 10 ~ 15min after the re-stretched to the required tension value, repeat after the sticky net to complete the stretching.

In Stretching the process should pay attention to the following:
Stretching four-side of the chuck in the 3mm gap between the maximum allowed within the network so that all are subject to tension wire and wire mesh to ensure that the same force;

Stretching units to correspond to the side of the chuck to ensure that when the wire mesh in the Stretching nearly square, uniform tension throughout;

screen frame size according to the four corners of left side of the tensile proper margin, can minimize the possibility of screen tearing;

Stretching can be made 24h after the screen printing version, because of the high tension network version of the 24h, the tension will drop 10% to 20%, and the tension loss occurs mostly within the first 4h, and then gradually stabilized ;

Stretching Stretching by the angle can be divided into direct and oblique stretching. To make the edge of the printing line straight, smooth, does not produce jagged, plate-making process while avoiding the moire produced (net wire and dot interference patterns generated), Stretching, the mesh of latitude and longitude lines and network box corresponding to the edge was a certain angle, this method is called oblique stretching. Stretching the point of view there are several general angle of 15 , 22.5 , 45 , 7.5 , 30 and so on. This point of view of several Stretching, 22.5 from the edge of the line has good flatness and smoothness. 90 Stretching Stretching is straight, the line from the edge of the poorest quality.

4 net pre-treatment Grinding using a dedicated network of cream, degreasing agent based on the coarse mesh degreasing treatment, to increase the non-porous surface of the smooth surface and remove the oil, increase the screen size and the combination of photosensitive materials, photosensitive materials to improve wire-line adhesion, increase the number of screen printing resistance, reduce screen in the production process on the photosensitive layer of the pinhole.

Although the dye sublimation printing technology known degree, smaller than the field office inkjet, laser two basic printing. However, its photo output, fabrics and glass body Transfer And so has a unique advantage, especially in photo printing effect, high image resolution, color transition of the natural, easy to store and other advantages, a large color digital photo-processing industry, the preferred printing method. The main reason for this is that the principle of dye-sublimation printing technology achieved a unique, and therefore below the working principle of the dye-sublimation printer for further clarification.

Printing technology using dye-sublimation photo printer

Sublimation printing technology, is the use of sublimation from the gas to solid and solid to gas without an intermediate state, the process of mutual transformation to achieve photo printing, that is, solid color printers use thermal recording head heated by direct sublimation to gas, photographic paper and then transfer to generate images. Sublimation printing using thermal sensor technology, the print will YMCO (yellow / products / green / protective film) three-color dye and a layer of protective film after evaporation followed by heat treatment in the special photographic paper imprint. Is the source of color dye ribbon, generally divided into yellow, goods, green three-plus protection film or yellow ribbon, goods, blue, black four-ribbon. Ribbon set on a drum, the drum is equipped with tens of thousands of semiconductor heating elements, heating elements constituted by the print head. When the ribbon at a certain temperature the thermal print head, the direct sublimation into gas and then sprayed into the print media on the formation of color.

Dye-sublimation printing technology As print, photo paper and ribbon with a roller at the same time, were heated under the print head using the print head diameter less than 40 m in the silicon lattice heat, dot matrix print head heating power will be painted on the dry solid ribbon melt ink. Heating process, the amazing transformation took place in about 320 degrees Fahrenheit, heat separate polymer molecules, when the print head off, the temperature drop from the gas into a solid ink, ink embedded in polymer. Polymer molecules aggregate together (this is why the dye-sublimation printing indelible reasons), when a color print after the beginning of the next automatically moved to a different color, resolution depends on the heating element, the amount of increase depends on the color decoration The temperature in the heating element, a piece of paper with sublimation ribbons produce millions of color mixture. Therefore, high-quality images available results.

Principle of sublimation printing technology Each heating head can be adjusted out of 256 high and low temperatures, then led to the degree of sublimation color, 256-class distinction, because it uses the color pigment into yellow, cyan, magenta three, can combined into the yellow color also has 256 256 256 cyan magenta = 16700000 kinds of trips are three-color effect can be achieved the performance of all 256 Levels 16.77 million continuous tone colors. Fresh color, structured, can involve subtle detail show color difference between adjacent; its special ribbon contains a unique protection film, you can achieve a continuous gradation of performance, compared with the ink-jet semi-Levels, the heat sublimation technology to achieve the photo quality is truly a printing technology; in photo preservation, since the protective layer, dye-sublimation printing technology in the water than the other, anti-UV and anti-fingerprint occupy a greater performance advantage.

Sublimation Printing Technology Working diagram Yellow, cyan, magenta and fusion of three primary colors can form a continuous color scale, while printing the same picture format, resolution less than the ink-jet printer, but print the form a continuous gradation of the print, but they can and high-end inkjet photo printers are comparable, the transition smooth natural picture colors are the main features of its print. The printing, the color dye-sublimation printer can be said that the best digital camera partner, therefore, this printer has color digital photo printer is often called, especially for fine print on the portrait demands delicate skin texture, but also not easy to fade with the characteristics of long-term preservation.

But in the process of sublimation printing, printing three colors is not the same time, but every time you use a color by three times to form the required color printing requirements. Is precisely for this reason, the print media in the printing process, a total of go through the printer three times, also dye-sublimation printer, the printing process is relatively slow, but the photo print quality high enough to compensate for this shortcoming.

Summary: dye-sublimation printing technology unique works, it’s high quality output as the biggest bright spot. Throughout the sublimation printing technology or there are some advantages and disadvantages, and they mainly: technology, dye-sublimation technology is that the printer uses ribbons, printed by heating the colored dye to the paper medium, the formation of color images. Performance, dye-sublimation technology-based applications, 300 * 300dpi resolution can be compared with 4800 4800dpi inkjet printing precision; in photo preservation, heat rise of the printer to print out the photos really achieve a permanent retention period; print speed , the output slowly. Consumables Costs, dye-sublimation printers use in product prices and costs are higher than those of office printing supplies.
