The development trend of digital printing equipment and materials

paper

the first generation of color digital toner printer is very sensitive to the properties of paper, which is related to the inherent structural design of the equipment. When imaging, it will be affected by the conductivity of paper, which is related to humidity. The second generation equipment improves the adaptability to various types of substrate materials by installing a dynamic control system. Now the third generation digital printing equipment has made significant improvements to the imaging principle, reducing its dependence on paper to the minimum. For example, iGen3 uses the gradually changing voltage value to transfer the image from the ribbon to the paper. The image transfer is assisted by a 60KHZ ultrasonic stimulation, which can realize the transfer of 100% toner. In other parts of the equipment, there is also a conveyor belt with controllable resistance coefficient to transfer the paper to the image transfer area. This greatly reduces the impact of the resistance coefficient of the paper

the dry toner system has smaller toner particles and lower fusion temperature, so it is easier to match with different types of paper. The wet toner system is more sensitive to the surface properties of the substrate materials, which requires the use of specially processed paper; However, some paper (mainly uncoated paper) can also undergo appropriate surface post-treatment to change the characteristics of the paper surface to adapt to this technology, which is a very necessary treatment process

from the above introduction, it can be seen that the future toner digital printing equipment will be more and more adaptable to paper, and can easily print on various types of paper. Therefore, the ultimate dependence on paper will become a history. Although the industry is still proposing the concept of electronic paper, it is more for technical reasons, but also for brand promotion and marketing expansion

the requirements for inkjet printing materials are very different. For all water-based and solvent based systems, the properties of paper are crucial if you want to achieve the desired image quality. To obtain ideal color saturation, special coated paper should be used, and the demand for this kind of paper will continue to grow. For the UV curing ink system, the best way to obtain the ideal quality is to use coating paper to seize the lead in the future development

ink

chemiicallypreparedton ers CPTs are mainly developed for toner based printing system. In the production process, the particle properties and size of toner have been carefully controlled, which has certain practical significance. The particle size of CPTs is between 310 microns. The ideal particle size can be selected according to the demand, but it will increase the difficulty of processing when the particle size is less than 8 microns. Liquid toner does not have this barrier, and smaller particles can be used without causing trouble. In the next five years, the development of this field will not be rapid unless the manufacturer's efficiency is significantly improved

inkjet inks should be able to well match the application needs of inkjet heads, printing materials and end users. The trend is to develop towards more pigment systems, which have better water fixation, light fixation and color fastness. Similarly, UV curing systems will continue to grow

uv ink has stronger spray stability than water-based and solvent-based inks, and its film-forming properties during printing and curing make it more widely used. The diversity and universality of UV ink applications make it the main growth point in the next stage

equipment

there are so many digital printing technologies that no company can fully develop and apply them. Therefore, we can see that, especially for inkjet technology, system integrators have built a bridge between different technology developers, end users and partners

for traditional printing machine manufacturers, this is a development direction. Especially for some manufacturers of small format offset printing equipment, the competition in this market branch will be more intense in the next few years. Therefore, it is best to enter into a cooperative relationship with a digital printing engine developer in order to effectively integrate new technologies with traditional equipment. This will result in an increase in the number of hybrid printing systems

another reason for looking for partners is that the development of digital printing systems requires huge capital investment, which is also a very big obstacle for some companies that are not very strong, especially in the field of toner printing systems

however, the situation is different for inkjet systems. Although partners are also required, the investment cost of such systems is low. Some technologies, such as inkjet head manufacturers, have large production capacity and economic strength. Therefore, the entry cost is not too high, but it also needs to promote the development of light composite materials required for clean energy products

the equipment developer implies that it is necessary to develop some completely innovative equipment for different end users, which can be operated only by workers with low technical level, so as to reduce the technical difficulty

in the future, digital printing will be integrated with other types of printing processes, and will also be combined with different needs and sales. Therefore, the sales of digital printing equipment and market applications will be very different, depending on the audience. The design and operating characteristics of the printing press will also take into account the user's environment and corresponding skills. In addition, after-sales support will also rise to a higher level
