Special Printing - Latest Trends (2)

Popular friction image printing

There are quite a few types of special printing. Table 1 is a list of commonly used special printing. The characteristics of special printing are briefly introduced in the table. About forty kinds are listed here. Among them, some of the effects are good, to obtain customer satisfaction, there are many uses, are frequently used in all aspects, and some are limited due to use, usually not easy to see. Among them, the ones that are often adopted by people are representative of friction printing. Its use is very wide, such as lottery tickets, game cards, rubbed lottery tickets, magazine appendices, postcards with lottery tickets, sporting goods, etc.

Friction image printing ( abbreviated as wiping printing ) uses offset printing to apply all the patterns and covered parts after printing to gray oil, and then to print the pattern of the part to be covered with silver ink screen printing. The ink residue will appear when rubbing the surface, so it cannot be used for food. Now that we have developed a tape that uses gravure tape to peel off the masked part of the ink ( scotch tape peeling image printing ) , by 2001, we have adopted screen printing to solve the problem of printing ink for printing on the transparent tape, so Bulk demand can also respond.

  Dainippon Printing Co., Ltd. has recently developed a new ink that can exhibit the same function as wipe printing without the appearance of ink residue. The printing ink used contains a material that is harder than a coin. When a coin is used to scrape the print, the ink is printed. On the part of the coin metal powder, instead of adhering to the pattern, it can be called pencil image printing.

Significantly improved three-dimensional printing and thermal printing

The very popular three-dimensional printing, as shown in Table 1, is a two-color three-dimensional printing with a lens, and there are 2D/3D holograms that rely on the interference of light to see a three-dimensional picture . Stereoscopic printing of lenses.

Conventionally, a three-dimensional map is a scanner that inputs text and graphics that are intended to appear three-dimensional, and then processes the images on a personal computer such as a Macintosh . The images are now printed on the Web site of the Internet . Website or public works website.

For stereo printing using a column lens, high-definition printing at 600 dpi is used, and the images therein can be clearly distinguished. With regard to thermal printing, vivid full-color images can be reproduced significantly compared with many years ago. All of these can give viewers a strong impression. As long as they are adopted in the planning, they will certainly bring about the effect of encouraging additional value printing.

Progressive offset printing

In fact, special printing has not yet been adopted in large numbers. The reason is not the issue of cost and time, but the lack of understanding of it.

In addition, there are a few offset printing that can already be solved, and because the patent right and other information are not clear, the general printing company is not easy to realize in the factory, and they do not know where to solve the external processing, and sometimes it is not clear how much the price is. , how long delivery deadlines and other conditions of dealing.

Some attempts have been made to transform special printing into offset printing. For example, inks for aroma printing have produced inks that can be used not only for a sheet-fed offset press, but also for a web offset press. Pearlescent ink printing also produces ink for lithographic printing, but its particle size is only slightly smaller than the particle size of the screen printing ink, so the bead effect is slightly inferior. Heat-sensitive printing and photochromic printing have already been implemented in the lithography test stage. Ways to connect friction printing printing to a coater on a lithographic printing press are also under consideration.

  In the general printing environment, lithography + on- line coating has been used instead of screen printing for thick-film printing, and parts that need to emphasize the printing effect can be printed with UV ink to increase gloss. In short, the field of solving special lithographic printing using lithographic printing is expanding.

Fairly clear patent

In the special printing patents, there are not only a few patents that have been explicitly declared expired, so the restrictions have been reduced, such as friction image printing, liquid crystal printing, foam printing, uplift printing, fragrance printing, pearl printing, and the like.

At present, the re-use of print and security considerations are increasingly important. Because the materials used in special printing are different from those used in ordinary printing inks, some use metal foils, and it is worth paying attention to from the viewpoint of waste recycling.

Regarding the above-mentioned circumstances, some of them need to be confirmed by individual investigations. Up till now, there has been no accusation on the special printing used in the magazine's planning. There have been changes in the use of other materials for novelty products originally made of polyvinyl chloride film. These ideas are also necessary from an environmental perspective.

The key lies in planning

The above describes the practical and convenient use of a variety of special printing and printed products, the application of them, whether to get the user's satisfaction, the key lies in how to adapt to the needs of the user to plan. It is not to tell the other party that there is a special printing method. It is necessary to find out what the user is seeking for. The purpose and theme of the user are what is required. How to use this type of special printing? Because the cost is definitely higher than that of general printing, so it must be To master the effect of using the following to plan. It is also important to adopt the opinions of art designers in the field when adopting.

Conclusion

This article has collected some recent information about special printing. To ask how many special printing, there are probably no more than 70 kinds of applications. Here is a brief list of 40 types. There are still banknote printing and stamp printing that people encounter every day. Tin prints for food cans, foam prints for blind readings, curved prints for non-planar surfaces, etc. have all been used very popularly and productively. At present, the role of special printing has drawn the attention of the printing industry in various countries at a time when the general printing market environment is sluggish. It is hoped that companies with aspirations will fully understand it, grasp it, and consciously apply special printing to obtain gratifying economic benefits.
