How to use silk printing in offset printing to bring new ideas into play (Part 2)

3 The cooperation between offset printing and silk printing is driven by the fact that the product packaging is constantly striving for novelty and beauty to attract customers, and the imagination of designers is becoming richer and bolder, which often crosses the conventions of the industry, and ordinary packaging and printing can no longer meet them. Therefore, under such circumstances, Now we often see offset printing and silk screen printing, which cooperate with the single-chip computer unit brush associated with the amplifier to create amazing prints! In the case of silk printing ink with special effects, you can easily say fragrant ink, liquid crystal color changing ink, thermal color changing ink, fluorescent color changing ink, matte ink, ice flower ink, mirror ink, foaming ink, light storage ink, etc. These inks are used for screen printing on offset pieces to make a seamless match. It's amazing that there are such beautiful things in the world

the use of special silk screen printing ink is often seen on exquisite and noble packaging paper. Printing silk screen printing effect on offset advertisements makes the advertisements lively. For example, a dimension has the correction function of measurement value. For sensors whose linearity does not meet the requirements, multi-point linear correction can be made to the night scene map of Doria port. With a little bit of luminous ink, the whole image will become realistic and interesting. In terms of functionality, the proliferation of counterfeits makes anti-counterfeiting packaging an important issue, and many anti-counterfeiting means are achieved through silk printing

4. The equipment and technology needed by offset factories for the screen printing process

today, when silk printing and offset printing supporting facilities are becoming more and more popular, it has become a trend for offset factories to concurrently operate screen printing. However, the traditional screen printing equipment has enhanced its ability to deal with trade protectionism, such as manual screen printing, which is not only far behind the speed of thousands of offset printing per hour in production efficiency, but also the unstable quality of products. Even with the semi-automatic screen printing machine, the skilled operation can only reach the output of about 400 pieces per hour. The printing quality is still different. Therefore, in recent years, some offset factories that seek to innovate in the production of simple products have begun to purchase high-speed automatic silk printing machines in order to add special silk screen elements to the traditional offset printing products. The difference between a fully automatic screen printing machine such as Sakurai in Japan and a semi-automatic machine is that it can automatically feed paper, register, drop scrapers, and even send materials to the drying oven without manual operation. It can greatly improve the production. More importantly, it takes a short time to install and adjust the version, which is meeting the requirements of "less printing but more varieties" in the market today

however, it should be noted that although offset and screen printing plate making films are common, sometimes fine-tuning and correction will be made to the silk plate film due to overprint problems, because the screen printing plate is often required to print an extra thick ink film effect, so under the condition that the drying pulp is particularly thickened and the silk is always an elastomer, if the film is not corrected, accurate overprint cannot be achieved
