In many life occasions in countries such as Europe and the United States, such as family dinners, classmate gatherings, birthday banquets, wedding banquets, etc., consumers usually want to show distinctive taste in every detail. For example, color printed napkins with special patterns are used in the event, and napkins with different patterns, different congratulatory texts and poems are printed to create a happy and warm atmosphere. Each family's kitchen is also equipped with various styles of napkins for different occasions and different purposes. Shops and supermarkets also sell, and there are design companies that specialize in designing colorful printed napkin patterns. We know that the investment in this color printing napkin equipment is very small, a set of equipment only needs 25,000 yuan, and the computer typing and engraving shop can make plates, which can be printed with various colors and patterns, and each napkin can also be based on customer requirements Printing shop emblems and promotional language to improve the brand and grade of the store, and sell well, while the cost only increased by 0.00001 yuan / sheet. However, in the current Chinese market, only a few foreign fast food chains, such as McDonald's, KFC, Pizza Hut, etc., will print simple patterns on napkins, and domestic catering industry and ordinary families rarely use personalized printed napkin products. There is no doubt that with the rapid development of China's economy, there will be more and more people's demand for personalized products, and personalized printed napkins will be a huge business opportunity. Requirements for substrates Because flexographic printing is ink-and-water printing, it is easy to cause swelling of the paper when it encounters water or ink. Local unevenness after printing affects the next printing, and it is also easy to cause wrinkles. At the same time, the swellable printing material exacerbates the fluctuation of tension It makes the accuracy of overprinting fluctuate greatly, making it difficult to produce good products. Secondly, due to the poor moisture resistance of toilet paper, after contact with the printing plate, it is easy to bring the loose fibers on the paper to the plate surface, resulting in paste printing, which makes the printing unable to continue, which more seriously affects the printing quality and yield. Ordinary facial tissue is a simple combination of two or three layers of wrinkle-free toilet paper hinged, then flexographically printed, and then embossed by toothed rollers and paper foil rollers. Most of the napkins in China belong to this type. Nowadays, most napkins on European and American dining tables are micro-sizing composite materials before printing. Such napkins are smooth, wrinkle-free, and have a texture and a thick sense. There is also a special product called micro-adhesive composite products with the printed layer in the middle. The three-layer structure has good texture and flexibility, and the product surface is more beautiful. Napkins produced by domestic printers should strive to change the method of embossing and pressing into micro-sizing and then printing, so as to make a qualitative leap in the quality of napkins. In addition, domestic napkins should also be improved in materials to narrow the gap with foreign products. For example, try to use high-purity wood pulp to produce base paper, add enough moisture resistance agent, and strive to meet the printing requirements on the surface flatness and moisture resistance. Requirements for ink As napkins are closely related to people's lives and related to the service industry, the inks used are required to be safe, non-toxic, strong in adhesion and non-bleeding. Napkin printing was originally printed with grease-based ink, which is characterized by good adaptability on the machine, but the smell of the printed matter is particularly large. Some napkin printers that use letterpress printing technology try to print napkins with glycol ink (washable) to eliminate the smell of the printed matter. However, this process encounters some difficulties, such as the occurrence of ink bleed paper when the printed matter encounters ethylene glycol (the liquid spreads out or penetrates in the paper); in addition, the on-machine suitability of this ink is not ideal. 1. Main advantages With the gradual progress of ink technology, napkin printing companies began to switch to more suitable flexographic printing water-based inks, and felt the advantages of pigment inks over dye inks. In this context, flexographic printing technology has stepped onto the stage of napkin printing, and its main advantages are as follows. (1) The odor is smaller, and it has good chemical resistance and wear resistance. (2) Reduce the phenomenon of ink bleeding. After some napkins are stained with beverages, the ink on them will smudge the white table cloth or clothes, which will lead to consumer complaints. The composition of water-based ink for flexographic printing contains resins and waxes that harden after drying. After pigments replace the dyes, the ink bleeding paper is reduced to a minimum. (3) Environmental protection: Because waste inks (such as water-based inks and solvent-based inks) can recover pigments, flexographic printing water-based inks are more environmentally friendly. Because no VOCs are produced, water-based inks for flexographic printing meet the environmental requirements for reducing VOC emissions. (4) Improve the profit of the enterprise: reducing the price pressure and ink inventory, which is very helpful to the operation of the enterprise. 2. Matters needing attention If you are considering entering the napkin printing market, then the most important thing is to understand the ink, and the relationship between ink and napkin printing. No matter which type of material is printed on the surface, it is important to understand that the colors printed on napkins have limitations. Therefore, pay special attention to the following points when selecting inks. (1) Have common sense in pigments. For example, to know which pigments are not suitable for printing on napkins, such as rose red, methyl violet, basic blue, red C precipitation pigments, etc., because these pigments will affect the ink after contact with certain compounds (such as water and ethanol, etc.) Resistance. (2) There are two types of ink available for napkin printing companies, one is finished ink and the other is concentrated ink. The finished ink can only be printed on a limited number of printing materials, and the concentrated ink can be printed on a variety of printing materials, but some additives need to be added. Concentrated inks are easy to use and can be applied to a variety of printing presses and anilox rollers. This is important because different models are often used for a batch of jobs. (3) In order to avoid the problem of poor resistance after napkin printing, it is necessary to understand what substances the napkin will be exposed to during the terminal application process, and it must be considered that the napkin printing ink must have a high alkali resistance, and also must be milk , Water and ethanol are resistant. The test methods developed by the enterprise should be repeatable to eliminate the influence of the operator's subjective factors on the test results. (4) To consider the safety of napkins in contact with the skin and eyes during use, it is also necessary to be familiar with some terms, such as occasional food contact, indirect food contact and direct food contact, and correctly select the ink that has passed the direct food contact certification. When the printer fully considers the above factors, it will limit the choice of ink color for napkin printing, especially many bright colors cannot be copied on napkins, and these limitations also increase the cost of ink. There is a famous saying in the business community: "Business originates from creativity." As a napkin printing to take into account both the catering industry and the printing industry, there will be many difficulties on the road of development, but we are convinced that as long as we continue to innovate and improve, we will make rapid progress in technology Today, it will have more room for development and bring huge business opportunities to the catering industry and printing industry. tv cabinet,tv unit, tv stands,floating tv stand Guangdong Planet Cabinetry Co., Ltd. , https://www.ptkitchencabinet.com
