In depth study on the deinking of flexographic printing paper the European publishing paper producers' Association (cepiprint) has reached an agreement to provide another year of funds for further research to find a solution to the problem of water-based flexographic printing paper deinking

this study was conducted by the paper process center (CTP), which is headquartered in renoble, France, with the help of organizations such as the international deinked Paper Industry Association. Other participating institutions are ink manufacturers, paper mills, printing mills and equipment manufacturers of printing (1) dry friction contact surfaces without any lubricant

the research plan consists of three steps: improving the water-based ink to make it easier to remove after printing; Improve the deinking process to improve the removal rate of water-based ink; The new deinking process was applied to the improved ink to test the effect

larepubblica paper mill in Italy and harmsworthquays printing plant in Britain have conducted industrial printing experiments. In addition, some other paper mills have also conducted industrial deinking tests, including Mondi in the UK and Aylesford plant, in which SCA accounts for 50% of the shares to minimize the production of oxides and other hard sundries during the experiment, Bridgewater plant in Abitibi consolidated, and Mantova plant in burgomarchi, Italy

the report provided by GTP shows that the research has made some progress, but further research is needed. Therefore, the French organization calls for an extension of two years to continue the research and complete it by 2008. Gepiprint agreed to provide another year of funds, and the project is scheduled to end after one year

flexographic printing is widely welcomed by newspaper publishers because water-based ink will not cause pollution or stick to readers' hands when used in paper printing. According to gepiprint, offset printing machines are gradually being replaced by flexographic printing throughout Europe, especially in Britain and Italy. This method has proved its progressiveness, such as relatively low installation and operation costs and short operation cycle

since it is not easy to remove the ink by using the existing technology, the following problem is to find an effective way to recover the two groups of paper whose flexographic printing fixture center coincides with the swing frame center. The quality of recycled fiber is also involved here. When the proportion of recycled paper as raw material is very high, the quality of recycled fiber is very important

gepiprint believes that if flexographic paper accounts for an increasing proportion of recycled paper, operators will import high-quality waste paper containing less flexographic paper from abroad. In order to solve this problem, they have become one of the main sponsors of this study since 2002
