Glassware must be cleaned up. After the flower paper is soaked in pure water to a saturated state, it should not continue to be soaked for a long time. And then the flower paper is attached to the surface of the product, scrape it back and forth with an elastic scraper to squeeze out the water and air in the interlayer between the colorless thin plastic film and the surface of the product, and at the same time ensure that the flower paper is not wrinkled and the pattern is not broken.

After the decals are dried, they are baked in the flower oven. The baking temperature is determined according to the melting temperature of the glaze of the flower paper. The baking temperature is determined according to the properties of the glassware glaze. When the baking temperature is low, the color glaze cannot be fully melted, and the color glaze pattern is dull; when the baking temperature is too high, the product can be deformed, the color glaze will flow, and the pattern will be burnt. The baking temperature of general products is controlled at about 20C below the softening temperature of the glassware.

Features of Advantages:

• Heat insulation and energy saving
• Radiation protection
• Bright in color
  
• Minimized color difference
  
• Excellent reproducibility
  
• Suitable for large-scale production

We also understand: It’s not just a label, it’s your brand.

Glassware or glass cups thermal transfer printing can be printed with ordinary ink, and the picture quality is high, but the excess part of the picture needs to be trimmed, and the quality of the paper must be good, the picture should be smooth after transfer, and it will not fade after 24 hours of cleaning, and it feels good. Compared with the sublimation ink transfer, it has an extra layer of fixing agent, and it also needs to reverse the picture. The difference is that it uses cotton material, but the hand feel is not as good as the sublimation ink transfer, and it is easy to appear if the paper quality is not good. Fading; (Dark): It can be printed with ordinary ink, the picture quality is high, the picture does not need to be reversed, and it is suitable for all kinds of fabrics. Comparable, its advantages are convenient without plate making, but the cost is high, and if the quality is not good, it is easy to fade, smoke, burst skin, not resistant to washing, not firm, feel hard and thick, and cannot be transferred.

Features of Advantages:

• Green environmental protection printing, in line with all harmless standards.
• The four-color printing pattern is formed at one time, without color registration.
• The transfer equipment is simple and the pattern effect is realistic.
  
• The loss of production is small, the cost is low, and added value is high.
  
• Bright colors, strong adhesion, durable wearing.

Screen printing belongs to stencil printing. It is called the four major printing methods together with lithographic printing, letterpress printing and gravure printing. Stencil printing includes transcription, perforated pattern, spray and screen printing. : When the printing plate is printed, the ink is transferred to the substrate (glass products, ceramics, etc.) through the holes of the stencil through a certain pressure to form images or texts.

Glass screen printing is to use screen printing plates and glass glazes to perform decorative printing on glass products. Glass glazes are also called glass inks and glass printing materials. It is a paste-like printing material made by mixing and stirring coloring materials and linking materials.

The coloring material is composed of inorganic pigments and low melting point flux (lead glass powder); the connecting material is commonly known as Liban oil in the glass screen printing industry. The printed glass products should be fired in a furnace at a temperature of 520~600 °C , the glaze printed on the glass surface can be consolidated on the glass to form colorful decorative patterns. If silk screen printing and other processing methods are used together, more ideal results will be obtained. For example, polishing, engraving, etching and other methods are used in Processing the glassware surface before or after printing can double the printing effect

Features of Advantages:

• Not limited by substrate size and shape
• Soft layout and small printing pressure
• Strong sense of 360°
  
• Strong optical resistance
  
• Convenient Plate making, cheap price
• strong adhesion

Glass Cups etching refers to the etching of glass with hydrofluoric acid to form a pattern. The glass is coated with paraffin, and then the pattern is carved on the paraffin with a tool, and then hydrofluoric acid is applied on it to obtain a glass etching pattern.

In the current upsurge of decoration and decoration, glass, mirrors, utensils, etc. engraved with various patterns and calligraphy fonts are very popular among consumers. The key to the engraving of glass containers lies in the preparation of etching solution. Now a raw material is easily purchased , Low cost, simple etching solution formulation and usage are described as follows:

50-60 ℃ hot water 18.4%, ammonium hydrofluoride 23.5%, oxalic acid 12.4%, ammonium sulfate 15.7%, glycerol 6.5%, barium sulfate 23.5%, in addition, a little agricultural production system dye is added for proper color matching. The above ingredients are mixed and stirred well That’s it. The raw materials in the formula are available in chemical stores all over the world. Before processing, wash the glass products in advance, and then warm them. The heating method depends on the size of the glass products. Put the small pieces into hot water and soak them. For a while, put the large pieces on the stove and bake for a while. Then use a brush to dip in the etching solution to write words or trace patterns on the glass surface. After about 2 minutes, a beautiful glass carving craftsmanship will be displayed in front of you.

Features of Advantages:

• Etching does not have peeling problems
• Etched glassware can be subjected to any cold processing, such as grinding, temperin. and effect no change.
• Weather resistance, especially for outdoor applications, will not reduce the effect exposed to wind and sun
  

UV printing is also called inkjet printing. It is first drawn on the computer, and then the desired pattern is printed through the printing nozzle. The printing method is similar to the principle of ordinary inkjet printers. Therefore, in the glass industry, is UV printing or screen printing more suitable?

There are relatively few color types for screen printing, because screen printing on the glassware only screen one color at a time. If you need to screen multiple colors, you need to produce multiple screens plate to screen different colors, while UV printing can be printed at one time, and do not need to make another screen version, just need to draw a computer map. Screen-printed on the glass bottles cannot produce gradient colors, but UV printing can print excellent graphics with bright colors and beautiful pictures. and gradient colors can be also printed at one time. However, UV printed patterns will fall off easily, especially over time, the printed patterns will fall off layer by layer, which is undoubtedly the Achilles heel of UV printing, and there is no better solution at present.

Features of Advantages:

• Multiple-colors Printing
• Vibrant & gradients colors,
• One-time plate making.
  

Frosted glass is also called frosted glass and dark glass. It is made of ordinary flat glass by mechanical sandblasting, manual grinding or hydrofluoric acid dissolution, and other methods to treat the surface to a uniform surface. It is often used in bathrooms, toilets, office doors, and windows that need to be concealed Partition. When using, the hair should be facing indoors.

Sandblasting is a kind of work that uses compressed air as power to push abrasives to the surface of the workpiece for processing. Abrasives that can be used, therefore, shot peening has been referred to as sandblasting at that time and for quite some time since. Sandblasted glassware is a process in which water is mixed with emery, and high pressure is sprayed on the surface of the glass to polish it.

Features of Advantages:

• Stunning smooth surface
• Compatible with multi-color screen prints
• Good light transmission
  
• Elegant appearance
• Anti-fingerprint
• High security

Glazing on the glass surface is a traditional surface decoration method for glass products, that is, a thin layer of colored low-melting glass is covered on the surface of glass products. Functional, such as luminous glaze. Glazing on glass surface is widely used in architectural glass, utensil glass, bottle glass, instrument glass, ampoules, etc.

Glazed glass container is made by coating a layer of colored fusible color glaze on the glass surface, heating it until the glaze melts, so that the glaze layer and the glass are firmly combined, and then annealed or tempered. It has good chemical stability and decorative properties, suitable for building exterior wall finishes

Glass glaze is made by mixing colorant and flux, and then stirring it with scraper oil (linker) into a paste.

Because the glass glaze is in powder form, it can be printed only after mixing with scraper oil to make it a paste color glaze. In order to make printing easier, and at the same time to prevent line disorder after printing, squeegee oil must be used as little as possible. The squeegee oil should be partially volatilized before being printed on the glass products and fired in the furnace, and should be completely volatilized before reaching the firing temperature. The low-temperature printing decoration process of glass packaging products uses low-temperature glass ink (cold printing color glaze) as the decorative material. The general curing temperature is 100-180 ° C, and the curing time is 10-15 minutes.

Features of Advantages:

• Aesthetics: The glass surface is bright in color,
• Strong adhesion between glaze and glass
• The flexural strength and tensile strength of glazed glass are 4-5 times that normal glass
  
• High security

The processing of vacuum electroplating on the glass cups, we also called ion plating. Ion coating is to use gas discharge to partially ionize the gas or the evaporated material under vacuum conditions, and deposit the evaporated material or reactant on the glass product under the bombardment of the gas ions or the evaporated material ions. There are many kinds of such ion plating. Generally, multi-arc ion plating and vacuum cathode magnetron sputtering method (vacuum sputtering method) are used for general glass products.

Features of Advantages:

• Luxury and premium features, brighter colors
• Improved performance and reduced premature wear and tear
• Smooth and uniform surface finish
• Resistance to extremely high temperatures
