Synthetic paper <br> The paper industry consumes a large amount of wood. Every year, many trees need to be felled around the world. Ecological imbalances have been caused in different places. Many people are deeply disturbed by this. However, due to environmental considerations and advances in technology, not only recycled paper of ever-increasing quality has been developed, but also papermaking techniques using fiber raw materials other than wood have been developed. These papermaking materials include bagasse, sugar cane, kenaf, ramie, and bamboo. The reason for choosing these papermaking materials is that they are fast-growing perennial herbs. One of the characteristics of these materials is that the maturation cycle is short, inexhaustible and renewable. In addition, experts are now studying the use of agricultural waste (including bagasse, banana rods, corn stover, and plant stems, etc.) in the paper industry. It is actually meant to refer to plant materials that are no longer being used in agriculture. In addition, there is a type of synthetic paper on the market, which is basically no longer used in wood. However, environmentalists still have doubts about this. Although some of the paper's ingredients can be recycled and recycled, it is necessary to use polymers such as plastics after all. Synthetic paper has superior performance in terms of opacity, water resistance, and durability, but there is still room for further improvement in ink affinity. Third, ink-jet printing and wide-format substrates <br> Wide-format inkjet printers, especially the emergence of large-scale printers, so that the types of materials contained in the substrate than traditional offset printing is much more. Since ink jet printers print at slower speeds than conventional printers, the requirements for substrate tension and tear resistance are low, and some fragile substrates are also suitable for such printing devices. This is not only a good news for digital artists, but it is also a great news for those who are engaged in sign design and POP/POS exhibitions. With the application of wide-format substrates, the problem of the hanging position of such prints has attracted people's attention. If you are hanging outside, consider the impact of weather factors such as rain and ultraviolet rays on prints. Otherwise, the ink on prints will fade due to smoke corrosion and air pollution, while outdoor prints hanging in indoor or indoor environments must also consider the harmful effects of cigarette smoke. This has also created concerns about the service life of inkjet printing products. Many activities have been held in the industry and many discussions have been held. The ink of traditional inkjet printers is dye-based, so that the printed colors are more vivid. But this aesthetic is only temporary, dye-based inks tend to fade, and sometimes the ink fades quickly and fades, even if the printed matter hangs indoors. Therefore, many ink-jet printer ink manufacturers and equipment vendors have developed pigment-based inks. Test results from many independent testing equipment indicate that the new inks are estimated to last for 50 years, 100 years, and even 200 years without noticeable fading. sign. The issue people now consider is not only ink, but also the service life of the substrate. The inks need to be printed on substrates that are compatible with them. We cannot print archived prints on old paper and hope that these prints will last for 100 years. The prolongation of the service life of the printed matter is a problem of the joint action of the ink and the substrate. Here, it is necessary to consider both chemical and physical factors. Therefore, for the printing of archives, we must consider the compatibility of the ink and the substrate of the printed matter. Both large-format paper and inkjet printer paper have some similarities in this regard. However, since ink jet printers have relatively high ink flow properties, they should be more suitable for papers with higher ink absorbency. Inkjet printer special papers are easily found on the market. These papers are available in a small format and include many varieties ranging from high gloss to high shading, from high thickness to low thickness. In addition to paper, ink-jet printing and wide-format substrates include canvases, which are quite popular among logo designers and art designers. Another important type of wide-format substrate media is various types of vinyl materials. The performance indexes of different types of vinyl substrates such as water resistance, discoloration and abrasion resistance are different. Vinyl materials are often used to print floor designs in shops or shopping centers, and these substrates can withstand pedestrians' long and long walks. Many vinyl materials are also used in the outer packaging of motor vehicles, and some even have magnetic backs, which, to a certain extent, work like the magnets of large refrigerators. There are many types of vinyl films on the market that can be printed directly on top of it, or they can be replicated on the transfer film. This is mainly used for backlighting exhibitions. One thing to watch out for when designing a backlight display: Do not use colors and designs that are too dark to transmit light. This reminder seems to be more than one move, but there are indeed people who have made this mistake. A new area of ​​wide-format imaging replication is fabric printing. Thanks to advances in the design of new substrates and machinery, it is now possible to print on a wide variety of fabrics. The most commonly used printing method is banner printing, but creative designers may still think of this technology in other applications. For example, in the printing of sportswear, many designers use this kind of printing method, and the effect is very satisfactory. Wide-format prints are generally fixed on display panels, foamed materials, or other rigid supports. They can also be hung with metal wires, ropes, or hooks. They can also be laminated using laminating techniques. Regardless of the type of exhibition, it must be ensured that the substrates can be fixed in the expected way. In addition, the issue of how to print the printed product and how to install the printed matter should also be considered. A 5 x 5 foot commercial display attached to a foamed material could not be directly transported by air. It can, of course, be done through hard work, but it is quite laborious. If such prints need to be shipped by ship, it is better to use printing materials that can be rolled up and put into a cylindrical parcel, which is both economical and avoids damage to the prints. With the advancement of technology, new types of wide-format substrates are emerging in an endless stream. Designers can choose according to specific circumstances. One thing to keep in mind when choosing a wide substrate is to ensure that the printed information is compatible with the substrate. It is now possible to print on large sheets of metal using fluorescent inks, but this design has not won the praise of those old-fashioned banking customers. So before you start designing, you have to consult with a wide format printer. Make sure the printed information is compatible with the substrate media. Finally, keep this in mind: Whether it is wide-format or narrow-width printing, the substrate chosen by the designer must be included in the design part of the design, which is as important as the design of the font, image, color and other aspects. The kinds of substrates that are applicable to various types of jobs are different, just as the fonts used for different types of jobs should also be different. We must consider the work in the printing industry in its entirety rather than biased. It is best to consult with the printers before starting the design, because their understanding of paper (substrates) is always more profound.
