How to make environmental friendly inks truly move towards the "green" road

although everyone knows that environmentally friendly ink is the development trend in the future, people obviously have not reached a consensus on what is truly environmentally friendly ink. Although we have not been able to give an accurate definition of green ink so far, one thing is certain: printing plants and their customers have increasingly strong demand for environmental protection products, which also prompted ink manufacturers to start developing various environmental protection products. But this is not an easy thing, and some people think that although ink can make your prints brighter and more environmentally friendly, it is the printing process that really works

Kenny Boyd, an environmental service consultant of Fujifilm seleco, pointed out that people have different understandings of environmentally friendly inks. Some people often ask whether a product is sustainable, but they don't know what sustainability means. This is the problem, and the best way to protect the environment is to start from the overall situation

environmental protection options

then, in today's increasingly demanding environmental protection, what is the response of ink manufacturers? Sun Chemical has said that it will use vegetable oil in its ink products. The production of the company's sheet fed and UV curing products always makes the pointer return to zero. John adkin, the supervisor (responsible for Europe and Africa), said: people must make a choice between using mineral oil and vegetable oil. We have developed products using these two raw materials, but through communication with customers and end users, we decided to choose crop raw materials that are more responsible for the environment

Fujifilm seleco claims that they have also developed a series of UV inks with environmental advantages. The company has a strong background in the field of silk printing and has made great progress in the digital field, especially in the large format printing market

Tudor Morgan, the company's European image marketing manager, explained that with the rise of inkjet technology, UV ink has also attracted more and more attention. This is a very stable product, which can cure 100% and will not emit VOC, so it can better meet customers' requirements for product health and safety

David grey, general manager of classic colors, believes that anhydrous ink is also a good choice for environmental protection. Consistent with the view of sunchem, Mr. gray also believes that soybean oil ink is less harmful to the environment than mineral ink, and the advantage of anhydrous ink is that it does not need to use any solution, so it can enable users to achieve color balance faster when printing on the machine, and it is easier to deink at the same time

this also fully proves that environmental friendly ink will not only have a positive impact on the whole printing process, but also promote the green process of an enterprise

environmental protection ring

Atkins believes that ink should give full play to its important role in the whole process of environmental loop of a printing enterprise, from production to recycling, printing market. Proper ink can reduce the energy consumption in the printing process: the newly emerging fast drying ink not only avoids the large demand for energy in the drying unit, but also meets the requirements of the traditional four-color printing process

Atkins explained that if you compare four-color printing and spot color printing, it is necessary to consider the design and process and the material itself when developing new products, and you will find that the former does not need to be cleaned in the process of version transfer

in order to calculate the carbon footprint left by the ink in the printing process, sunchem and Bertelsmann's subsidiary in France jointly conducted a survey and found that the carbon emission of the ink accounted for about 5% of the total carbon emission of the printing process

this is a very meaningful project, which can let us clearly know how much impact ink can have on the environmental protection of the whole printing process

sunchem believes that if an ink wants to truly achieve green environmental protection, it must have as many environmental protection features as possible. For example, although some inks can get rid of the dependence on VOC, they cannot be recycled, so they cannot be called green inks

take flexo printing inks as an example. Because most of them are water-based and do not contain VOC, they have obvious environmental advantages, but at the same time, flexo printing products cannot be 100% recycled. Therefore, before choosing an ink product, you must fully understand it and avoid generalizing

environmental protection is only a problem that ink manufacturers need to overcome in the process of developing green ink. Another problem that cannot be ignored is the cost

for example, anhydrous ink does have some environmental advantages, but its cost is also higher than other inks. As gray of classic colors said: not everyone will choose anhydrous ink, because it has high requirements for process and involves a large cost. But now many modern printing machines are equipped with temperature control and anhydrous printing functions, which greatly facilitates the choice of users

clear choice

the emergence of plant inks also raises the question of whether it is ethical to use crops as raw materials for production. Atkins of Sun Chemical also admitted that this was a potential problem, but he also believed that the choice of the printing industry was very clear. He said: you can get raw materials from mineral oil or vegetable oil, and you can also produce high-quality inks, but also ensure their safety. Like our tensile testing machine, we have selected soybeans and rapeseed as raw materials for ink production, and these raw materials will not be used less and less like mineral oil

The limitation of UV ink is that it cannot be attached to some substrates. Plastic is an example. Boyd of Fujifilm seleco also admitted that UV ink is the best environmental protection option, but it cannot achieve the ideal ink coverage

ink manufacturers have also encountered some stability problems in the process of developing new products, but now they have basically overcome them, and Fuji serik has also found some problems related to UV inkjet inks

in addition, the life cycle of products, waste, the health and safety of equipment operators and the atmospheric environment are also issues that ink manufacturers always pay attention to

in some cases, giving up chemical composition means that the sales volume of ink manufacturers will be affected in the short term. Morgan added: some chemical ingredients have not been banned by the European Union, but our company has always paid more attention to environmental protection, so we decided not to use these chemicals anymore. Customers want to find reliable partners, and hope that if there is anything unclear, we can provide them with high-quality service and technical support. Environmental performance is an issue that we will always consider in the development of all products

opinions vary

at present, there are many views around green ink, which is enough to make everyone feel headache. Boyd of Fujifilm seleco said: I can imagine how difficult it is for printing houses. They should not only consider health and safety issues, but also find ways to improve energy efficiency and reduce waste in the printing market. All their decisions are based on customer needs

Boyd suggested that when choosing environmentally friendly inks, we must shop around and solicit as many opinions as possible. Every printing enterprise is now facing certain environmental pressure, which is determined by the needs of the market and customers

however, printing enterprises should also be soberly aware that ink is not the whole of the printing process. Although green ink may have a little impact on the production process, only a comprehensive environmental protection plan can ensure the long-term stable development of a printing enterprise

colorific company has launched colorific bio series inks with 90% biodegradable ingredients and ISO9001 certification. This product is specially designed for printing plants using Epson DX3 and DX4 print heads, but it is also suitable for substrates without lamination and coating

in May 2009, one solution, a Belgian ink company, launched a series of environmentally friendly solvent based inks at the fespa digital exhibition. Onejade series is specially designed for large format printing, while onepearl is a UV curing ink, which has 8 colors and can maintain its color for at least 36 months outdoors

also in May, 2009, durst company launched what is said to be the world's first digital ink approved to use Nordic swanlabel. This ink does not contain VOC, and has also passed the certification of toy standard en17 part3. It absolutely does not contain some heavy metals that are forbidden to be used in children's products
