Flexo Printing: Batch and Environmental Protection

What is flexo printing: Flexo printing is a branch of letterpress printing. Flexographic printing is similar to letterpress printing in terms of printing principle. It differs from traditional letterpress printing in printing plate, ink composition and embossing process. The transfer of the image is accomplished by a photochemical reaction resulting in a printing late or a patterned rubber stick. In the United States, which originated in the early 1920s, the early use of aniline inks was toxic and failed to develop. Since then, the ink factory began to use acceptable color agents, and was renamed the Flexographic Process at the 14th Packaging Conference in the United States in 1952.

The main advantages:

1. The substrate has strong adaptability;
2. Fast printing speed: Usually, the normal printing speed of the flexographic printing plate can reach 100 m/min or more;
3. The UV ink or ordinary ink used is environmentally friendly.
4, large amount of ink, good saturation, suitable for large color, freehand design, soft gradient, blur effect is good;
5, more suitable for standardization: through the anilox roller on the network to transfer the amount of ink, you can change the anilox roller to adjust the amount of ink, once the appropriate selection of anilox roller, the color difference during the printing process is very small, to a certain extent This can reduce the basis for the operator’s experience;
6, has a rich connection after processing, easier to achieve the need for combination printing.

Limitations:

1, in the fine text and lines, dot gradient, the relative letterpress and lithography is not enough fine and soft;
2. The fuselage printing machine has a long fuselage, and the material loss of the tuning machine is relatively large;
3, high plate making requirements, high edition fees, there are certain requirements for the number of printing, short-term profit margin is small;
4. The plates and raw and auxiliary materials have not been localized domestically, and most of them still rely on imports;
5, the use of water-based ink, the speed is too fast when drying is not timely, cutting into a single sheet when the convergence error-prone;
6, overprint accuracy, outlets less than offset.

Field of application: Suitable for large-volume printing of paper, plastic, stickers.

Future trends: Offset printing, gravure printing and other printing methods are preconceived. People are accustomed to comparing the advantages of these printing methods with the disadvantages of flexographic printing. The characteristics of flexographic printing are often overlooked. In fact, the experience of foreign countries has proved that flexo printing can print high-grade prints. However, there must be corresponding equipment and corresponding plate raw and auxiliary materials as well as mature processes and high-level operators. With the continuous improvement of people's living standards, it also promotes a new round of technological innovation in flexographic printing. The main innovations of flexo printing are: 1 Non-shaft independent driving of flexo printing machine; 2 Widely used sleeve technology; 3 Digital plate making; 4CDI imaging technology; 5 automatic register control technology; 6UV drying technology. With the localization of flexographic plates, raw materials and auxiliary materials, the cost of flexo printing in China will become lower and lower, and the prospects for flexo printing will be bright.

Combination printing: the director of the collective home

What is combination printing: Combining printing refers to the production of various types of printing and finishing machines, which are composed of screen printing lines. The more common combinations are screen printing, flexo printing, letterpress, offset printing, and hot stamping. As the combination printing method adapts to the needs of the development of the modern printing industry, it brings huge profits to the printing manufacturers, and therefore it is rapidly developed. According to industry insiders, with the continuous development of related technologies, combination printing will gradually develop into a mainstream way of label printing.

The main advantages:

1. On-line simultaneous completion of a product's various processing procedures, high production efficiency;
2. Save on the number of waste products, reduce the loss rate of printed materials;
3. The combination printer has a compact structure, a small footprint, and easy operation.
4. Fewer operators
5. The total investment in equipment is small;
6. Increasing the difficulty of counterfeiting is conducive to anti-counterfeiting and at the same time improves the quality and grade of printed matter.

Difficulty of combination printing process:

1. The calculation of register zooming between different printing methods;
2. Ink control is difficult;
3. It must be ensured that the sequence of the units used in the combined press has sufficient variability;
4. Set the printing unit speed according to the printing requirements;
5. The operator's quality requirements are high.

Future trends: At present, the combination of plastic, soft, concave, convex, and screen printing equipment has pushed traditional labels and trademarks to new heights; while digital systems have opened up new markets for labels and trademarks. In the packaging field, a single printing method has become increasingly unable to adapt to market demands. In the next 5 to 10 years, the combination printing will achieve faster development. The current development of combination printing is still in its infancy, and many technical issues and material issues need to be improved and improved. With the increasingly personalized and diversified printing, the application of combination printing will become more and more extensive.

Applicable areas: mainly used for smoke labels and washing, anti-counterfeiting features.

Digital Printing: Frontiers and Future

What is digital printing: Digital printing is a very comprehensive technology that covers a number of technical fields including printing, electronics, computers, networking, and communications. The so-called digital printing means that electronic files are transmitted directly from the computer to the printing press, thereby eliminating steps such as color separation, imposition, plate making, and test run. It brings one of the most effective ways for printing: from input to output, the entire process can be controlled by one person to achieve a print. This small amount of printing is suitable for four-color proofing and reasonable variety of printing. Digital printing realizes the concept of "distribution before printing."

Advantage:

1. No need for plate making, one for printing, improving production efficiency;
2. The number of prints is controllable, reducing production costs;
3. Can print up to 230 lines / inch high-precision images, greatly enhance the appearance of the label;
4. Variable data printing;
5. Can realize spot color printing of labels;
6. Wide selection of label materials;
7. Increase the security of the label.

Limitations:

1. The uneven quality of various inks and papers in China caused a wide range of printing costs and prices, and the differences were obvious.
2. Digital printing machine OEM-type paper supply and ink supply methods, so that digital printing does not have the conditions to reduce prices, making it difficult to adapt to low-cost competition;
3. As the most typical advantage of digital printing - the space for personalized printing has not yet been developed;
4. In the case of short-run printing, digital printing needs to better align with offset printing;
5. On-line processing and other high-automated operation methods are the biggest features of digital printing, but the excessive domestic labor force causes the production cost to be too low, and does not have the conditions to stimulate the wide application of this technology.

Future trends:

According to different digital technologies, digital printing systems with different functions can be designed in the future:

1. The combination of simple CTP technology and small offset printing technology forms a non-integrated digital printing system;
2. The digital printing system is realized by the combination of organic silver salt plate making technology and small offset printing technology;
3. The combination of high-speed inkjet technology and small offset printing technology enables inexpensive digital printing systems.
The rapid development of digital printing has enabled the public to quickly recognize digital printing and tasted the benefits of using digital printing. However, it has also brought public awareness into the misunderstanding that digital quick printing is equivalent to digital printing. In fact, digital printing has 80% of its own market. Digital printing and offset printing are two different customer groups. With the development of technology, these markets include personalized printing, variable data printing, and on-demand publishing, all of which are impossible to achieve with traditional printing.
