The difference between Solvent-based Ink and Water-based Ink.
Traditional Solvent-based Ink mainly includes benzene, xylene and other aromatic hydrocarbons and alcohols, ketones (such as butanone) and acetic ester solvents. At the same time, it is essential to add stabilizer. Aromatic hydrocarbon has great harm to human body, as well as heavy metal pigments such as lead and chromium. Water-based Ink is based on water as a new type of printing ink dispersant, it greatly reduces the use of organic solvents and thus solves the harm of printing and reading process on the human body,as well as greatly reduces the pollution to the surrounding environment and destruction, ensure the sustainable development of ecological environment.
According to reports, in United States and some European countries have banned using Solvent-based Ink, instead of environmental ink. At present, 40% factories of the use Water-based Ink. In other developed countries, such as Japan, Germany and France, more and more use Water-based Ink in plastic film printing also, Britain enacted banned using Solvent-based Ink printing and packaging for food in June 2003.
