What is the difference between flexo printing and silk screen printing?

Flexo printing is a type of direct printing that uses an elastic, raised image plate. The plate is cemented to the plate cylinder. The plate is fed by an engraved metal anilox roller.

Due to the high elasticity of flexographic plates, liquid or grease inks can be transferred to almost all types of materials. Flexographic printing is a light pressure brush. According to the characteristics of flexographic printing, the original suitable for flexographic printing should be selected when selecting the original

1.It is necessary to design various patterns suitable for flexible printing, such as lines and color blocks, and spot colors are preferred. 2.

Excessively fine text and lines (especially inverted white requirements) flexo printing is difficult to achieve and should be avoided when designing. 3.The design should avoid strict registration requirements.

4.The characteristics of the printing machine and whether the ink can restore the original truthfully, and the halftone original should avoid the design and selection of large areas of high-gloss originals and **. 5.

Reducing and enlarging at high magnifications should be avoided in the size of the original, as these will cause a loss of layers. Silk screen printing is the abbreviation of "screen printing". Screen printing is to stretch silk fabrics, synthetic fiber fabrics or metal wire mesh on the screen frame, and use the method of hand-engraved paint film or photochemical plate making to make screen printing plates.

Modern screen printing technology uses photosensitive materials to make screen printing plates through photographic plate making. During printing, through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the ** part, forming the same ** as the original. The screen printing equipment is simple, easy to operate, simple to print and plate-making, low cost and strong adaptability.

Screen printing has a wide range of applicationsCommon prints are: color oil paintings, posters, business cards, bound covers, commodity signs, and printing and dyeing textiles, etc. First of all, the plate-making process produces a developer, the ink used produces an ink barrel, and the cleaning process produces cleaning wastewater or waste rags.

One is digital printing and the other is monochrome printing.

Compared with offset printing, there are mainly the following differences:

1. Reproducible range of color values. 1% 99% (or 2% 98%) for offset printing and 3% 95% for flexo printing.

2. Expansion of outlets (50%). 15% 20% for offset printing and 30% 40% for flexo printing.

3. Add the number of network cables. Offset printing is generally up to 175 line inches, while flexo printing and screen lines are generally not more than 150 line inches.

Due to the high elasticity of flexographic plates, which can transfer liquid or grease inks to almost all types of materials, flexographic printing is light pressure printing.

Flexo printing is a type of direct printing and is known as flexographic printing due to the use of an image plate that has a flexible, raised face. The flexographic plate is glued to the plate cylinder, and the plate is fed with ink by an engraved metal anilox roller.

The barcode anti-counterfeiting and anti-channeling management software system can help enterprises to achieve strict supervision and control of the orderly flow of key commodities in the distribution network, improve the channel management level of enterprises, and reduce and avoid channel risks. Through the application of encrypted 2D barcode technology, the system accurately and confidentially identifies key commodities. Flexo printing makes the goods have the greatest inclusiveness, flexibility and environmental protection, makes the packaging and trademark materials complex and diversified, the design is characterized by professional color blocks, lines and texts, and the printing is characterized by multiple batches and small quantities; The improvement and development of flexo printing process and supporting technologies, such as direct plate making, high-quality UV ink, high-precision anilox roller, servo motor, etc.; The original one-stop production, with the cost-effective advantage of comprehensive production, the unit type flexo printing machine in the high-end market like a tiger.

Flexibility and environmental friendliness make the materials of packaging and trademark-related information complex and diversified, the design is characterized by professional color blocks, lines and texts, and the printing is characterized by multiple batches and small quantities; The improvement and development of flexo printing process and supporting technologies, such as direct plate making, high-quality UV ink, high-precision anilox roller, servo motor, etc.; The original one-stop production, with the cost-effective advantage of comprehensive production, the unit type flexo printing machine in the high-end market like a tiger. At present, carton printing and cardboard printing technology has been relatively mature, which makes the mixed production line become a packaging product, all of which are a strong guarantee to improve the added value of products, innovative printing means, it does not need to add additional equipment, packaging. Mounting the tile state and rolling on the rolling car, then the corrugated should be opened, which can be a variety of packaging products.

In the field of paper packaging printing in China, it accounts for the majority of the share of packaging and decoration printing, and the ink used in the wheel is diverse, and a reasonable production process is formulated.

Flexographic printing has unique flexibility, economy, and is beneficial to the protection of the environment, in line with the hygiene standards of food packaging and printing, which is also one of the reasons why the flexographic printing process has developed rapidly in foreign countries. However, judging from the current situation in China, offset printing is more popular, gravure printing has also occupied a large market in the packaging industry, and flexographic printing technology started relatively late, although in recent years has indeed made great progress, but there is still a big gap with the international advanced technology level. A range of reproducible color values.

1% 99% (or 2% 98%) for offset printing and 3% 95% for flexo printing. Expansion of the network (50%). 15% 20% for offset printing, 30% 40% for flexo printing.

Add the number of network cables. Offset printing is generally up to 175 line inches, while flexo printing and screen lines are generally not more than 150 line inches.
