What is Gravure Printing?

2011-11-17 Looking at the printing plates of Gravure Printing, you'll find that printing parts of the plate are lower than blank parts, and all the blankparts are on one level. The deepness of the printed part concave influence the depth of the tone. That is, the deeper printed parts concav is, the darker tone will be.  the plate cylinder of the printing plates are painted with ink fully, but the squeegee device will scrape off  raised ink while printing. then the printing ink will be colored on the paper by the  pressure.
