1. Printing related environmental protection concepts.

VOC of volatile organic compounds.

• the United States astmd3960-98 standard defines VOC as any organic compound that can participate in atmospheric photochemical reactions;

Y DIN55649-2000 standard definition of a VOC, Germany is in normal pressure condition, the boiling point or initial boiling point lower than or equal to 250 ℃ of any organic compounds;

• in the context of environmental protection, VOC emission is involved in atmospheric photochemical reaction to generate ozone directly causing air pollution;

Printing common volatile organic compounds.

•Gasoline (100% voc100% vocable)

•Blanketwash eraser (90-95%VOC)

•Alcohol Alcohol IPA isopropanol (100%VOC)

VOC is harmful to the body.

IPA alcohol:

• a dangerous source of fire.

• the central nervous system that affects the human body.

• stimulate the eyes, nose and other organs.

• irritation and destruction of the skin.

• make people dizzy.

Gasoline/kerosene:

• a dangerous fire source that irritates and damages the skin, damaging the central nervous system.

2. Several testing standards should be paid attention to in the printing industry.

GB9685 - China national food packaging convention.

Since June 1, 2009, the hygienic standard for the use of additives in food containers and packaging materials (gb9685-2008) has been officially implemented. The standard stipulates the use principle of 959 kinds of additives for food containers and packaging materials, usage scope, maximum usage, specific transfer amount or maximum residual amount and other restrictive requirements. This standard emphasizes that substances not specified in the list shall not be used for processing food containers and packaging materials.

ROHS - eu electronics packaging convention.

RoHS, a mandatory standard set by eu legislation, is called "Restriction on the use of certain harmful elements in electrical and electrical equipment".

OfHazardousSubstances). The standard has been officially implemented since 1 July 2006. It is mainly used to regulate the materials and process standards of electronic and electrical products, making it more conducive to human health and environmental protection. The aim of this standard is to eliminate the six substances of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated biphenyl ether in motor electronic products, and the concentration of lead should not exceed 0.1%.

En71-3 and en71-9 - eu toy packaging convention.

EN71 is the normative standard for toy products in the eu market. Children is the most concern and care for the whole society, children's favorite toys generally market developing rapidly, at the same time due to various aspects the quality problem to all kinds of toys children harm also happen from time to tome, so the toys from around the world to the domestic markets are increasingly demanding.

EN71 relates to the printing industry in parts en71-3 and en71-9, the former is the liquid class standard which is used in printing ink, light oil and other substances, the latter is the standard for the use of paper in printing. The main detection of eight heavy metals, applicable age labels, formaldehyde and other content.

HR4040 - American toy packaging convention.

H.R.4040 is an acronym for the U.S. consumer product safety improvement act (CPSIA/HR4040), which was formally signed into law by President bush on August 14, 2008.

The bill is the toughest consumer protection act since the consumer product safety commission (CPSC) was established in 1972. In addition to the stricter requirements for lead in children's products, the new law also sets new rules for the amount of phthalates in toys and children's care products.

The idea of low-carbon environmental printing.

1. Analyze the carbon emission of the printing process (analysis of the production of VOC)

2. Take corresponding measures to reduce carbon emission (reduce VOC emission)

3. Optimize the production process to stabilize the printing process and improve the production efficiency.

4. Select high-quality environmental materials.
