Photogravure ink equal to cut ink and its application

This invention relates to a photograghic intaglio printing ink which equals to carving intaglio printing ink. It can be used in photographic intaglio printer, and its outstanding feature is that the price of the printer is cheap, lithographic cost is low, and the post-treatment step of sewage during printing process is unneeded, so the sewage from carving intaglio printing ink printing process is eradicated completely and with no environmental pollution, and the printing ink is no waste and its non-offset performance is very good. It dries quickly, so it shortens the production cycle and saves the production buildings and land. The color of ink of its printing is of distinct hierachical structure and strong stereoscopic feeling. Its printing effect is the same as that of carving intaglio printings. The physicochemical fastness of its printing is superior to that of carving intaglio printings. Its printing cost is low.
