Rotogravure Printing is one of 4 most popular Printing Methods in the World.

    Rotogravure Printing is in contrast to Letterpress Printing, the image area of which plate cylinder is lower than the plane of Printing. The Rotogravure Printing is to print through the depth of printing plate to show the variable color gradation from the original manuscript.

    If the Image Area is in deep sunken, it will fill more ink and left thick ink layers after embossing. If the Image Area is in shallow sunken, it will fill less ink and left thin ink layers after embossing. The Ink quantity of Printing Plate is corresponding to the gradation of original manuscript. In the printing, daub over the whole printing plate cylinder through ink fountain or ink transferring Roller, then scrape the inks where non-image area locates with scraper; and the inks that filled inside the sunken area will be transferred to the surface of printed materials.
