Environmental protection pressure faced by the printing industry

with the increasing popularity of large-scale printing, printing plants have also suffered unprecedented environmental pressure and the huge risk of losing customers

with the continuous progress of technology, large format printing can not only produce dazzling display images, but also provide greater creative space for graphic designers. However, like commercial printing enterprises, large format printing enterprises are also facing great pressure to achieve green printing. They must become more environmentally friendly

in the face of such market changes, many equipment and consumables manufacturers have taken positive measures to reduce the impact of large-scale printing on the environment. However, Stephen Goddard, the Environmental Leadership Project Director of HP printing solutions, believes that the impact of large format printing on the environment is not as great as people think, and the carbon footprint of the printing industry is larger than that of large format printing

the rise of digital printing is one of the main reasons why the field of large format printing began to vigorously reduce environmental hazards

according to Paul machine, an environmental consultant, digital printing does not experience the same learning curve as silk printing or offset printing, because it has eliminated some chaotic procedures related to printing, and digital printing can be produced according to your needs, thus avoiding the waste of materials

but this does not mean that there has been no progress with the large format printing process. For example, the prepress Department has greatly reduced the amount of chemicals with the help of computer direct production technology

selection of inks

another area that has made great progress in recent years is the manufacturing industry of large format printing inks. In addition to the increasing variety of inks, UV inks have gradually attracted the attention of insiders. According to mark Stephenson, UK sales director of Fuji digital solutions, UV ink can provide users with green environmental protection characteristics that solvent based inks do not have. Generally speaking, solvent based inks can only leave 20% of the pigment on the substrate, while UV inks can leave 100% of the pigment

ultrasonic fatigue test of Fuji serico can be carried out under different load characteristics, different environments and temperatures. It has been trying to promote its own UV ink, but with the increasing temperature of inkjet technology, these products have always been unable to meet the market demand. People who support UV ink said that the reason why this kind of ink is environmentally friendly is that it does not contain volatile organic compounds

stephenson said: UV ink can be printed on almost all substrates. Compared with solvent ink, the cost of this product is higher, but due to the poor characteristics of EVA plastic material in softness, compression resistance, slip resistance, elasticity and material tensile properties, it has been recognized by more and more printing plants. Now we can complete the whole process in less than 6 hours and quickly prepare aerogel. Many large format printing enterprises have said that their next purchase goal is UV printing equipment

however, UV ink is not perfect. It is very fragile and easy to crack, while the solvent based ink has strong stretching ability, which is very suitable for printing body stickers and other products. Of course, people have another option, which is latex water-based ink

Goddard of HP believes that its Designjet l25500 latex water-based ink printer is a real environmental protection device. He said: both ink and printing consumables can become major problems affecting the environment. UV curing ink may have certain environmental advantages, but it also has its own shortcomings. The biggest feature of latex water-based ink is that it is not flammable

the new HP latex water-based ink printing technology not only expands the range of HP ink technology, but also provides a good alternative for a variety of indoor and outdoor applications of printing service providers. The new HP water-based latex ink can produce tasteless prints, which are not only durable, but also produce vivid images. These inks also have wide versatility, and can provide large volume printing services with the support of HP large format scanning and printing technology. Printing enterprises can not only expand printing capacity and business, but also reduce the environmental pollution caused by printing. HP latex ink provides durable and excellent printing effect. It is suitable for a variety of substrates produced by HP or non HP. Even products without film can be displayed outdoors for up to three years. From this point of view alone, Designjet l25500 latex water-based ink printer has the strength to compete with Epson, Yumu, Roland and other environmental printers

for Goddard's environmental protection speech, Stephenson also gave his own view. He believed that the drying speed of environmental protection solvents was slow, and it was necessary to install heating equipment for the printing machine, which would not only consume more electricity, but also increase the energy consumption of the equipment

in order to refute Stephenson's claim, although the manufacturer considered many HP's Goddard when designing, they said that their Designjet printers have passed the certification of European energy star, and at present, only two printers in the world have passed the certification of this energy plan

reducing energy consumption is the goal pursued by all equipment manufacturers, but the realization of this goal mainly depends on the whole production process adopted by printing enterprises. As machine pointed out, waste is the number one enemy of printing enterprises, and only a few printing enterprises know how waste is generated
