12 effective guidelines for green printing

1. Understand relevant terms

you must be familiar with environmental protection terms related to the printing industry, so as to facilitate the selection of environmentally friendly materials. The following are some common terms:

VL rgin flber (primary fiber): extract 100% pure fiber from raw materials. Post consumer materials

V 0 C S: volatile organic compounds (such as volatile oil-based inks)

PCF: chlorine free treatment

TCF: completely chlorine free

ECF: chlorine free principle

2. To protect and save resources, the relevant environmental protection association estimates that in order to provide fibers for papermaking, More than one billion trees are cut down in the United States every year. This not only destroys forests, but also affects air quality and consumes water resources. One way to save resources is to use recycled paper to improve the utilization rate of materials after consumption. Using recycled paper can reduce garbage and reduce water and energy consumption. The standard for testing recycled paper is to see the proportion of secondary fibers after manual treatment

3. choose environmental friendly ink

solvent based ink will produce volatile organic substances. After the paper printed with this ink is thrown into the garbage, toxic organic substances will penetrate into the soil, affect human health, and may lead to cancer or other physiological diseases. This toxin will also be released into the air as the ink dries

soybean ink is a good environmental friendly ink with low content of volatile organic substances. This kind of ink is not only environmentally friendly, but also has good printing quality and low cost. Newspapers, magazines and many other printed materials can be printed with soybean ink

4. adopt digital printing

experts on environmental protection in papermaking and printing industries recommend the use of digital printing. Because the digital printing process is short, four-color printing can be carried out. The printing range includes business cards, stationery, advertising lists, and most live parts are products with a printing volume of less than 1000 copies and a format of 14in.120in. In comparison, using digital printing is better than using printing field 2006. 1 1 No。 248 soy ink is more environmentally friendly. Soybean ink contains 86% oil, which is difficult to decompose, while digital printing uses 100% non-toxic ink, which produces less chemical waste

5. Choose environmentally friendly paper

at present, there are many environmentally friendly paper on the market that can replace traditional paper, lk~denimblues (100% recycled Blue J eancotton) and Yupo synthetic paper, which have good environmental protection and durability. Some products can also use paper made of kenaf fiber and hemp fiber. For example, a new type of paper called terraskin has a small smell of raw materials, its strength can be comparable to synthetic paper, and its printing performance is equivalent to coated paper. This kind of paper is not only ink-saving, non-toxic, but also waterproof

6. Choose environmentally friendly bleach

smooth and bright white paper generally needs to be bleached. Before choosing paper, it is best to know whether the treatment process of this kind of paper meets the requirements of environmental protection. To make the paper white, it usually needs to be chlorinated, and chlorine dioxide (used in swimming pools) is the most commonly used. Although chloride is safer than pure chlorine, it will still cause some pollution. It is better to use PCF (chlorine free treatment) fhtcf (control each control stage step by step and in sequence, completely chlorine free) bleaching, that is, to use oxide instead of chloride for bleaching. At present, only a part of recycled paper has a small volume, and PCF bleaching is used, while TCF bleaching is still less used

for products treated with PCF and TCF, the chlorine free products association will grant environmental protection marks. You can check whether there are such marks when purchasing paper

7. Guide customers

many companies have to deal with printing and packaging enterprises. For packaging and printing, some large companies such as IBM, Coca Cola and McDonald's are advocating the use of 100% recycled post consumption materials, but not all enterprises understand the concept of green printing. Printing enterprises can provide customers with some environmental protection advice

8. Use environmental protection in actual production

to set an example for other enterprises in environmental protection, you can refer to the following:

when using ink, first check how many colors of ink you need to use, and whether you can use two colors instead of multi colors

use the color card to control the optimal amount of ink (which also reduces the emission of v0c)

in order to avoid waste of paper materials, use paper of standard printing specifications (such as 23inx 35In, 25in 38in, 26in 4oin, 28In 40in). When the format is too large, choose paper of special specifications and sizes. Since paper is sold in pounds, this method can save your customers a lot of money

9. reduce costs

some environmental protection products may be more expensive, but don't give up environmental protection because of cost constraints. Instead, we should creatively reduce costs. Comprehensive solutions can be adopted: for example, using expensive paper can save costs in other aspects; Business cards and postcards can be printed on one page if they use the same recycled paper. In the long run, your customers may save more money, and they also respect the environment

10. understand the relevant industrial standards

the United States Environmental Protection Agency (EPA) stipulates that paper and paper products purchased by the federal government must contain a certain proportion of recycled waste paper, office paper must contain at least 30% recycled waste paper, and coated paper and commercial paper must contain 10%. These relevant standards can be used for reference when selecting paper. In addition, we also need to understand the meaning of some relevant standard marks, such as the mark of cfucfpa, IS0, etc

11. environmental protection is considered in the design

a good design is not only attractive in appearance, but also multifunctional. Designers should consider the problem of waste. From an aesthetic point of view, a good design is quite important. But the design of things is to be thrown into the garbage, even if the appearance is beautiful, it is not a good design. Waste recycling is necessary, because it is too wasteful to be thrown away. If customers are not willing to use recycled paper with high recycled waste paper, they can find ways to reduce the number of pages. Of course, it is best to choose different paper according to different situations. For example, some exquisite advertising leaflets are printed on high-grade coated paper, while products with more words and less image requirements can be printed on uncoated paper with high recycled waste paper

1 2. Broaden our horizons

environmental protection represents the trend and trend of new products and technologies. Although environmental design is challenging, it is absolutely feasible and highly rewarding. Printing enterprises can understand or learn from the achievements of other enterprises in green printing. The following are some examples of green printing. New technology

waterless printing: waterless ink can be washed to reduce volatile organic substances emitted during the printing process (www.warerl ess.org). Utilization of wind energy: wind energy will not cause pollution. For papermaking, wind power can be used. Mohawk paper is an example. Bottle product

glue free product is a CD packaging box, which cleverly uses the edge folding method to avoid glue bonding, and uses recycled cardboard, which has strong packaging and good printing quality. Choice of tree free: using recycled paper and synthetic paper provides users with many choices. Terraskin (as shown in Figure 2) is a tree free, chlorine free paper with high durability and water resistance

more choices: in the 1980s and 1990s, the postcards designed by ALR des ign in Figure 4 of the last century began to enter the green industrial design activities, and many paper mills began to use recycled waste for papermaking

neenah paper, Domtar Inc, CAS cades fine papers group, ro11and Inc, scheufe1 en andmonadnock paper Mi US Inc, etc. all provide choices for environmentally conscious enterprises and designers

centralized printing: Figure 4 is a postcard designed by ALR design. Nine different postcards are printed on the same page. The paper used is 100% recycled paper, which effectively reflects the environmental protection design and printing

environmental protection sign

fsc: Forest Stewardship Council (FSC) is a non win deformation measurement range that promotes forests: 0 (1) 0mm; For profit-making organizations, trademarks are only granted to products that implement FSC standards and guidelines

s0y ink: the product is marked with the logo of soy ink, indicating that it uses environmental friendly soybean ink and is pollution-free

pr0cesed ch1orine free: this sign indicates that there is no chlorine or chloride treatment during paper manufacturing, and at least 30% recycled waste paper is used
