1. Lottery screen printing
In the past 10 years, the need for masking ink has increased year by year. On the offset printed text, numbers, and marks, use masking ink to screen-thick film printing, so that it is completely masked, and then made into a card is a lottery ticket. There are various forms of lottery, such as sports lottery, social welfare fund-raising lottery, etc. In this lottery, you can see the characters and numbers printed below by scratching off the masked ink with coins or nails.
In addition, by masking images, text and numbers can be combined into a variety of interesting entertainment, which is very popular.
1. The composition of lottery tickets, because most lottery tickets are disposable, so they are printed on paper, usually 150-200g / m2 coated paper. First, printing text, numbers, images, etc. with offset printing. The printing surface of offset printing is smooth, which is very beneficial for the last concealed screen printing. The printing surface after offset printing must be coated with an outer layer with good transparency. Its function is not only to make the masking ink peelable, but also to make the offset print bbs.wescn.com stable. Then use masking ink to make a final screen printing on this coating, generally only for partial masking thick film printing on letters and numbers.
2. Lottery performance requirements.
â‘ After the stable masking ink is printed on the lottery ticket, it should be easily peeled off with nails or coins. Lottery tickets printed with this ink must be stable for at least one year of circulation.
â‘¡ After peeling off the masking ink, the exposed characters and numbers cannot be contaminated by the ink.
â‘¢The masking ink should have sufficient masking property.
â‘£ The ink film that masks the ink must have a certain toughness, that is, the surface of the ink film cannot be damaged due to some external force during the drying and cutting operations of the lottery.
From the above points, â‘¢ and â‘£ are almost determined by the performance of the masking ink, so it is very important to choose the right ink. â‘ and â‘¡ are determined by the degree of adhesion between the coated paper and the masking ink. The faults in the previous experiments are mainly â‘ and â‘¡, so this is a very critical issue. [next]
Second, the silk screen of electric decoration advertising board
Electric decorative advertising boards generally project light from the inside of the advertising board to make the surface more beautiful. The materials used mainly include acrylic plates and glass plates. In addition to printing, the board is also decorated with cutout text and lines. The main processes of screen-printed electrical decoration advertising boards are surface printing, inside printing, full shading printing, etc.
The most commonly used is the electric decoration advertising board printed on the inside. Generally, the screen printing is carried out on the inside of the acrylic board, and finally the white solid printing. The surface can be formed into a bright and bright decorative pattern. If the light inside disappears, light from other directions is reflected on the surface, and various colors appear.
When printing on the surface, a milky white translucent board is generally used. Since all-white printing is not required, unevenness in quality rarely occurs, but scratches are likely to occur because of surface printing.
When shading, it can be printed in two ways. If the surface wants to use full red shading, before printing all red, use the same printing plate for shading purposes, print a silver or gray, and then print all red on top. When performing electrical decoration, only the text or pattern part protrudes, which is very clear and beautiful, so it is often used for the printing of road signs or guide plates.
When printing on acrylic, the material itself is charged, and it is easy to attach dust, so be very careful.
Since the dust adheres to the electric decorative plate is very obvious, in order to eliminate dust and prevent static electricity, wipe the substrate with alcohol before printing. Because the light is emitted from the inside, the printed scraper marks are also very obvious. For this reason, pay attention to the squeegee grinding, printing pressure, printing speed, etc., and try to reduce uneven printing. Due to the use of good light-transmitting inks, after printing and electrical decoration, the color tone seems to have completely different changes. When combined with other colors, if the light transmission is not observed, it is possible to make a product that is different from the customer's requirements. In four-color color printing, if the color is adjusted without observing the light transmission, a very light and fuzzy image may be formed. [next]
Third, the silk screen of the metal advertising board
The metal advertising board refers to the guide board and the advertising board whose material is the metal board. Its predecessor is the enamel advertising board and the melamine advertising board. The metal material is mainly aluminum and stainless steel. The surface of stainless steel has the advantage of not rusting. After screen printing, the surface can be coated with hardener for processing. Aluminum can use its plasticity to carry out relief processing by pressure method to make the surface have concave and convex patterns, strengthen the three-dimensional sense and improve the visual effect.
The earliest metal billboards are enamel billboards, which use galvanized iron plates as materials, use enamel to prevent rust, and are mostly used in billboards, place names, etc. Although this brand is highly adaptable to climate, it takes time to process and coloring is not easy. With the development of spraying technology, melamine billboards began to appear, which improved the anti-rust performance, and can be colored by screen printing through the cut-and-cut method. Since the billboard began to use hard plastic as the main material, the melamine advertising board has given people a feeling that bbs.wescn.com is outdated. The iron plate billboard is outdated and outdated. Due to its own weight, the processing is affected, and it is also difficult to circulate the goods.
The main material of the metal advertising board has been changed to aluminum or thin zinc plate, these are light materials, good processability, even if the size is large, it is easy to handle. In order to increase the strength of the metal thin plate, a part of the protrusions can be made into ribs, and the material consumption is about the same as that of the flat plate.
Fourth, the silk screen of stainless steel products
There are many methods for processing on the surface of stainless steel, which can be roughly divided into two types. One is to process the stainless steel to make it have a surface gloss, and the artistic processing of using gloss contrast to form patterns; the other is to give color to the composition of the patterns Art processing. Among them, the typical examples of the screen printing method are etching processing and color spraying processing.
The etching processing method is to screen-print the acid-resistant protective film on the surface of stainless steel with color, and then etch it with ferrous chloride solution to form an artistic pattern. The color spray method is to spray color particles after screen printing to form a pear-like surface and form an artistic pattern.
In recent years, in order to adapt to the diversification of stainless steel applications and increasingly high artistic requirements, the "color art" processing method with colors has been developed and has become the mainstream in this field. The method of imparting color to stainless steel includes a method of screen printing color ink followed by firing and a chemical coloring method.
The process of chemical coloring art processing method for stainless steel products is: stainless steel products â†’ silk screen â†’ oxidation coloring â†’ alkali treatment â†’ finished products.
The process of etching art processing method of stainless steel products is: stainless steel products â†’ silk screen â†’ etching â†’ alkali treatment â†’ oxidation coloring â†’ finished products.
The technological process of the color painting art processing method of stainless steel products is: stainless steel products â†’ silk screen â†’ etching â†’ alkali treatment â†’ silk screen â†’ oxidation coloring â†’ alkali treatment â†’ finished product.
The chemical coloring method of stainless steel does not use pigments and dyes. Instead, the stainless steel is immersed in a heated concentrated chromium sulfate solution for chemical coloring, which is characterized by good food resistance. The ink used in this processing method must have a very strong acid resistance, and generally use a UV vulcanized ink with special properties that is compatible with the processing process. [next]
5. The silk screen of the light reflector
The light reflector is a screen-printed object that is irradiated by the headlight or other lights of the car, and the irradiated object reflects light toward the light source without being affected by the irradiation angle or the climate. The reflection is formed by hollow glass particles with a diameter of about 40 Î¼m, and a reflective layer at other centers. Its soft sheet-like support has an adhesive layer and a peeling layer on the surface. Generally, a reflective layer is provided on the acrylic resin plate. The reflective layer is printed with a screen printing method by adding a certain amount of hollow glass particles with a resin with strong transparency. When printing, we must carefully select the mesh size, hole width (opening) and type of hollow glass particles. The hollow glass particles are regularly arranged.
This kind of printing is mostly used for various signs and commercial advertisements, etc., so that it can be confirmed in darker occasions. In addition, it can also be used for printing road signs, airway signs, life-saving appliances, safety helmets, etc.
Sixth, transfer anodized aluminum with silk screen
Gorgeous and beautiful, bright colors of anodized aluminum are printed on the substrate by the hot stamping machine, and its beautiful color has won wide praise. However, sometimes the bronzing machine will encounter products that are not suitable for mechanical bronzing, and customers stubbornly do not use screen printing gold. In the dilemma, the unique screen printing plate transfer anodized aluminum shows its superiority. Hot stamping machine stamping anodized aluminum is mainly based on temperature and pressure, and screen transfer anodized aluminum is based on the role of adhesive. The reason why the adhesive can transfer anodized aluminum is because the outermost layer of anodized aluminum is composed of an adhesive layer.
During the transfer operation of anodized aluminum, the printed graphics must first be made into a screen version, and the graphics on the version should be clear. Then use a silk screen to print a layer of adhesive on the substrate, and then paste the anodized aluminum on it, and then use cotton or sponge to gently press on the graphic area. Dry, fast when tearing), clear and bright anodized aluminum graphics appear on the part with adhesive.
Adhesive formulation is the key to transfer. The formula should be separately formulated according to the nature of the printed matter, the nature of the anodized aluminum adhesive layer and the suitability of the screen version. The viscosity and concentration of the formula should be properly prepared. For example, bbs.wescn.com, when transferring cloth and PVC, polystyrene plastic products and wood products, the adhesive formula is:
Perchlorethylene resin 100g
Vinyl chloride resin can also be used instead of polyvinyl chloride resin or two kinds of blending. Low molecular weight polyvinyl chloride resin. When transferring celluloid plastic products, the xylene in the above adhesive formula can be changed to acetone. When transferring organic glass products, some chloroform can be added. When transferring metal, ceramic and glass products, the adhesive formula is: 100% epoxy resin. (O) Dibutyl benzoate 3% ï½ž 5%, ethylenediamine 12% ï½ž 15% (the concentration is too high, diluent can be added). [next]
Seven, silk screen prints
In recent years, silk screen prints have been promoted and popularized in China, and many high-level works have appeared. The art level of silk screen prints is close to woodblock prints, but the production of silkscreen prints is much simpler than that of woodcut prints. In addition to the commonly used paper, the substrates for silk-screen prints include cloth, plexiglass, wooden boards, porcelain plates, and metal plates. This has broadened the way for the development of silk screen prints in practical arts, such as the production of posters, decorative paintings, clothing, scarves, etc. in the form of silk screen prints. Printmakers can fully devote themselves to the design and production of practical art to improve their artistic level. Wall hangings, screens, curtains, sofa covers, mattresses, etc. are all areas where silkscreen prints can play a role. On the one hand, making purely artistic prints, on the one hand, opening up the position of prints in practical art, and playing a role in beautifying people's lives, this is very meaningful.
8. Lacquer silk screen
Screen printing has been introduced into the traditional industry, one of which is the lacquerware industry. The representative lacquerware products such as bowls, drawers and boxes can also be adapted to the modern lifestyle. The implementation of this printing method has improved the value of the product. Among these decorative methods, the most commonly used is silk screen printing of gold powder and silver powder on lacquerware.
1. Screen printing and lacquer lacquer technology. Lacquer lacquering technology is to spray black lacquer and lacquer on wood and plastic base, and then draw a pattern on the surface with paint, and then apply gold and silver on bbs.wescn.com before the paint is dried and hardened. The lacquer painting, high lacquer painting, polished lacquer painting.
In the lacquer process, there are two types of manual and automatic printing with silk screen, and manual is the main method. The first process of the lacquer is to make the designed pattern outline into a printing plate. In silk screen printing, this process belongs to plate making, so it is omitted. The following is a description in order.
2. Printing Equipment. For flat printing equipment of pots, drawers and boxes. First place the plate on the stage, then place the lacquer ware on the stage and position it, and fix the lacquer ware after positioning.
When printing in large quantities, a positioning and fixing device (for example, a convex wooden table on which the printing material can be inserted) is required, and the gap between the printing surface and the printing surface is 1 to 2 mm. The curved surface printing of cans and bowls substrates, with the round screen as the center, the scraper down, and the substrate runs upward. When the scraper, screen and substrate are in contact, the pressure of the rotary force of the screen will cause the substrate to print The object rotates for printing.
3. Modulation of printing lacquer. Here is just a brief introduction to the paint mixing method. The lacquer itself cannot be printed as an ink. The viscosity of the lacquer is low, and it is easy to mix with air bubbles, which makes the printing surface blisters and fails to meet the requirements of accurate printing. Therefore, in order to achieve a good ink state of the paint, it needs to be modulated.
Compared with other coatings, the drying conditions of the paints are completely different, they are dried by oxidation, therefore, the temperature and humidity need to be controlled. Viscosity adjustment of printing lacquer: mix ferric oxide, titanium oxide, protein, anhydrous silicic acid, etc. with paint, mix thoroughly, seal for 4-5 days, the viscosity can be adjusted to about 500 poise, and can be used for printing Ink.
4. Lacquer (ink) drying and lacquer time. The drying of paint is greatly affected by temperature and humidity. The optimal drying conditions are 30-35 Â° C and 75% -80% humidity. The lacquer time is directly proportional to the drying time. The greater the viscosity of the paint (ink), the faster the drying.
5. Printing accuracy. When the paint liquid for adjusting the paint (ink) is 65% or more or 40% or less, the printing conditions are not ideal. That is, when there is a lot of paint, the plate is not good, leaving traces of paint.
Especially on the curved surface of the printing material, it can be clearly seen in the printing direction. In addition, when the paint liquid is low, the paint has poor fluidity, the printed pattern surface is unstable, and traces of net lines are left, especially when printing gold and silver powder. Generally, 250-300 mesh nylon mesh is used for the screen mesh, and its precision is good. Because paint requires special drying conditions, it is not easy to block holes in the screen, and printing operability is good.
Today, a multitude of wipes exist for almost every imaginable use and niche. Body Cleansing Wipes are available for removing makeup, showering, wiping away sweat, sanitizing, and hygienic cleaning. There are exfoliating wipes, wipes for camping, wipes for traveling, workout wipes, and wipes for many, many other uses. Body Wipes provide us with many benefits and consumers have come to rely on them.
1,Body wipes are Convenient
Convenience is without a doubt the primary reason why body wipes have become so popular. Since their introduction in the early 1960s, hundreds of body wipe products for a wide range of diverse uses have become available. You can find them at your local grocery store, drug store, and online. Fast-paced lifestyles resulting from the contemporary demands of home, job, family, and recreational pursuits keep us busy all day long. We all love Body Wet Wipes because they save us time.
Carrying the equivalent of a quick shower in your pocket or purse is a big deal for men and women on the go. No matter the situation, the ability to pull out a wipe and freshen up is one of the benefits of the modern age. Here`s a partial list of the different kinds of cleansing body wipes that are readily available.
2. Body Wipes Are Easy to Use
Going hand-in-hand with the convenience of using body wipes is their ease of use. No instructions are needed. Simply remove a body wipe from its individual wrapper or box and use it. Then, the used wipe goes in the trash or is flushed away. No rinsing, washing, or reusing the wipe is necessary.
For the most part, the disposal of body wipes has minimal environmental impact. Some flushable wipes can wreak havoc on community sewer systemsâ€“especially body wipes that are not made of cellulose fibers. Wipes made from materials other than cellulose (paper) biodegrade too slowly and can clog sewer system pumps.
3. Body Wipes Can Be Antibacterial
You don`t have to suffer from germaphobia (fear of germs) to use antibacterial body wipes. Touching surfaces in public places that have been touched by hordes of other people is a great way to catch something. Wipes provide us with a quick way to protect ourselves.
It`s not just shopping cart handles. It`s doorknobs, restaurant table-tops, handrails, and the weight machines at your gym. Andâ€“horror of horrorsâ€“children, too. In fact, children can be the grimiest and most germ-laden carriers of all.
Many researchers now say that washing hands frequently with regular soap is just as effective as using an antibacterial wipe or antibacterial soap. But if soap and water are not available, an antibacterial body wipe may be just the thing you need in a pinch.
4. Body Wipes Are Great for a Quick Freshen-Up
Ever feel like you need to freshen-up after lunchtime run? Or when you`re on the road or between connecting flights? Perhaps you have a social event planned right after work. Anytime you need to freshen up but are short on time, personal body wipes can help you feel ready and rejuvenated.
A body cleansing wipe can clear away perspiration, dirt, and unpleasant odor, helping you feel refreshed and revitalized.
5. Wipes for When You Can`t Shower
You may be among those who can`t bear the thought of not taking a shower every day. But what about those times when showering is impossible? There will always be those times when taking a shower isn`t an option. It could be a camping trip, a long flight, an unexpected travel delay, or even an emergency situation. When it happens, having a supply of shower wipes or bath wipes can certainly brighten your day.
[Body shower" wipes have recently become quite popular among consumers. Some full-body shower wipes can even temporarily replace taking a shower. These wipes contain a mild cleaning solution, vitamin E, aloe vera, and they`re alcohol-free. They`re larger and thicker than typical body wipes, tooâ€“about the size of a standard washcloth but several times thicker.
Shower body wipes can remove sweat, body odor, and dirt. They also moisturize, dry quickly and leave no sticky residue. They`re safe for cleaning all areas of your body. Some have a medicinal smell that disappears quickly as the skin dries. Full body shower wipes are helpful for those who may be bedridden and unable to bathe.
6. Body Wipes for Hygienic Cleaning
Cleaning up [down there" has a long historyâ€“ as long as humans have been roaming around planet earth. Before the advent of toilet paper, invented in the 19 century, we homo sapiens used dried leaves, clay, newspapers, and even Sears catalogs. Now, we have body cleansing wipes for use in the bathroom. What started out as a welcomed and convenient way to wipe baby bottoms has now grown into a billion-dollar business for adults, too.
However, there are differences of opinion among physicians as to the medical benefits of using body wipes as toilet paper. Some medical professionals say there`s no additional benefit compared to normal wiping with toilet paper, while others note that a sanitary wipe is more thorough. Most people would agree that using bathroom wipes just feels better.
Most leading brands of hygienic bathroom wipes are alcohol and paraben-free. They contain mild cleaning solutions and may contain aloe and vitamin E. Typically, these wipes are also fragrance-free. Because flushed wipes were known to clogging sewer systems, many wipes today are made with cellulose or plant-based fibers which biodegrade quickly.
7. Wipes for Exfoliating
Exfoliating wipes are different from facial Cleaning Wipes . While both are designed to clean the skin, exfoliating wipes are designed to remove dead skin cells, oil, dirt, and germs. The definition of exfoliate is [wash or rub with a granular substance to remove dead cells from the surface." A good exfoliating wipe will unclog skin pores and allow your facial skin to breathe.
What exactly makes an exfoliating wipe different? The ingredients. Because exfoliating wipes are made to scrub and exfoliate, their texture will be rougher. Microbeads are the most common additive that gives exfoliating wipes the ability to remove dead skin without harming the living skin. Other ingredients may include oils, vitamins, glycerin, crushed oats, or wax beads.
8. Wipes for Women
Ladies, it`s easy to become dependent on body wipes for the face. It`s a great way to remove makeup. With hundreds of brands available in the makeup aisle or online, there`s something to meet the needs and wants of anyone wearing makeup. Yes, they`re easy to use, but here are some things you may not know about face wipes.
Do makeup wipes clean effectively? While quick and convenient, some dermatologists say that face wipes may not be the best way to remove makeup at the end of a long day. Instead of cleansing and removing makeup, wipes may just be pushing the dirt and makeup around your visage. They may be even lead to clogged pores. But when soap and water aren`t available or you have time constraints, makeup wipes will certainly do.
Wipes are differentâ€“so choose wisely. When shopping for Facial Wipes , remember there are differences. Some wipes are meant for removing eye makeup, while others are designed for deep cleaning. It`s important to carefully read the labels.
Great for the beach. Facial Cleansing Wipes are great for a day in the sun and sand. You can use them to remove old sunscreen and to refresh your skin.
Great for facial cleansing on the go. After a long plane, car or train ride, a facial cleansing wipe can help you feel reinvigorated. And, you won`t rile the TSA with a package of face wipes.
Effective for removing stains. Facial body wipes can even remove small stains from your clothing. Gently pat a face wipe on a newly acquired stain and the stain will likely disappear. Don`t wait. If the stain has been there too long, all the rubbing in the world with your face wipe won`t do any good.
Facial wipes are not a substitute for washing. While using a face wipe to remove makeup is quick and convenient, don`t get out of the habit of washing your face. A thorough and complete cleansing of the face still requires good ol` soap (mild) and water.
Get rid of deodorant stains. Don`t you hate it when you`re applying deodorant and accidentally get some on your dark shirt or dress? When that happens, grab a face wipe and gently wipe the stain away. This should take care of any unwanted deodorant residue.
Clean up when dying hair. If you`re one who likes coloring your own hair, you know that when finished, there`s always dye on your forehead and neck. A face wipe will quickly and gently remove dye from your skin.
