There much of a difference in special printing intaglio printing and offset printing, first put the amplification of about ten times, the peripheral line with hand carved on a zinc plate, and a narrowing of the external mechanical retractedthe original carved on a piece of about eight inch copper sheet. And the copper sheet is coated with some corrosionfilms, because copper is on the hook word peripheral line, so want to hand the film gross body ground scrape, and then use the potion will image depth, finally still need to use a magnifying glass and the carving knife, the patience toline edge, angle position fix, a chrome plated, this plate can be accomplished.

In printing, which of course you want to use a particular gravure printing machine. It is the method of plate after the ink tank, then through a steel piece straight away excess ink layout, and then after a paper, the excess ink to wipe clean.When the concave printing hid with ink on paper, the pressure, ink is transferred to the paper, because the ink is thick, so dry after the convex feeling. If you do hit convex effect, increase the pressure, not ink, can cause subtleletterpress effect.
