according to Yao Weidong, standing vice president of the Ji'nan seal industry association, the commonly used seals are mostly toxic and harmful chemical synthetic materials, which are not environmentally friendly, easy to be deformed, easy to shrink, and poor in imprinting, and are difficult to prevent false identification. Like the commonly used hard seal material will shrink or even deform after a certain time, this is not consistent with the original stamp retained in the seal file. When the seal is printed, the printing oil is dipped in and the size of the seal is strong. Discrimination brings difficulties. In order to effectively manage the public seal from the source and eliminate the "public carrot stamp", which can be engraved on the street stalls, it is necessary to promote the new type of anti counterfeiting information.
it is understood that the new type of back ink seal products are not only clear, but also consistent and easy to use, especially for the identification of the authenticity of the seal. Because of its unique design, it can automatically control the amount of dip oil and keep the stamping force consistent. Detected by the Ministry of public security's counterfeit product quality inspection center, it has been printed for 220 thousand times without distortion. The use of anti-counterfeiting products is internationally recognized as an environmental protection product. It is an upgraded product recommended by the China seal industry association.
uses the new technology for the public seal, and is convenient for the users to identify them. It is beneficial to the Ji'nan city to further strengthen the control of the public seal and to expend the counterfeit seal from the market. "The new seal with unified standard, unified channel and unified material will effectively eliminate the" radish seal ". Yao Weidong said that Ji'nan will solve the problem of illegally carving the official seal from the raw materials of the unified official seal.
