Inkjet printing to multiple environmental challenges facing – ink-jet printing,
Currently the industry's most popular topic is probably the two environments and digital printing, while the deinking of digital printing is the intersection of these two topics. To improve the environmental credibility of the print is to strengthen its media portfolio in a key step in an important position, but the adoption of digital technology to enhance the overall efficiency of the printing is also very important.

Digital printing deinking problems printing companies will make a headache depends on the specific circumstances of these printers. International Deinking Industry Association (INGEDE) that this is its member companies are facing the biggest threat, but also affect the production of quality recycled paper. However, the new digital printing press manufacturers and HP Indigo sector?? INGEDE claim that their device potential problems?? Has repeatedly said that they did not find any problems so far, but will not guarantee that any problems. Hewlett-Packard, General Chi, companies such as Kodak and Océ last year set up a digital printing inking Alliance (DPDA), the main purpose is to allow people to better understand the deinking problems with the supply chain Cooperation Partners to develop effective management systems. Ingede Fisher on DPDA press spokesman welcomed the establishment, he said: "This is a manufacturer of inkjet devices in dealing with the issue of the first step deinking, their products must be recyclable." Fishbein Hill explained that the Association would like people to take initiative to solve the digital printing of deinking problems and avoid repeat of its member companies in over 20 years ago the introduction of flexo equipment in the past. He said: "We have seen the seriousness of this issue and hope to ink-jet equipment manufacturers in bringing products to market before finding the ideal solution." Ingede hope that any new printing technology can not recovery system to change the current deinking treatment under the premise of. According to Fisher introduced in Germany, any one of the existing recovery system to break the new products must be labeled. Germany and the European Union have strict rules through legislation that all new products can be recycled. Despite some strong reactions Ingede, but did inkjet equipment suppliers has increased the degree of attention to this issue. They said that regardless of the deinking performance digital printing is now how they will do their utmost to improve the efficiency of paper recycling, which is no doubt. Kodak Graphic Communications Group's media business development manager DonBurns said: "We are also compatible with existing systems, but with the expansion of inkjet printing market, which might have become a very prominent issue." Digital printing now all incoming paper deinking processes account for only less than 5% share, while inkjet printing in which the percentage is negligible, and most of dry toner devices. Select a different ink-jet equipment suppliers and the biggest difference between Ingede just can not recall the number of digital prints. The former believe that as long as the total printing ink jet printing in the proportion of no more than 10%, it will not be a problem deinking, while the latter argue that even if the total digital printing in the print share is only 5% It will also bring trouble. Kodak Burns that the inking in a question, inkjet printing output growth of at least another 100 times. Hewlett-Packard's inkjet development and environmental strategy expert NilsMiller said: "Although we in the printing market, the development of a small proportion, but also the need for de-inking technology research." Deinking is part of the process of paper recycling, which the paper reuse has a crucial role. The technology is primarily used to produce recycled paper mill, and the most suitable printing process with the mainstream use: offset printing and gravure printing. Deinking is a combined application of chemical and physical process. It is primarily through the use of effective deinking agent deinking equipment to oil-based ink, and paper pulp separation of impurities, which are recycled pulp. Hewlett-Packard, General Chi, Kodak, Océ and Screen launch of a new generation of commercial companies such as inkjet printers are water-based inks used, which obviously can not copy the oil-based ink used in deinking process. There is a similar dye-based ink problem, because dyes can not be removed. Fisher likened this issue wash color red socks. For those who have invested in a closed water system of the European deinking enterprises, the problem is particularly serious; while in other areas of business, you can use washing process. Digital inkjet equipment suppliers say they can dye ink for inking deal with, and for pigment inkjet ink, they can find a reasonable solution.
