    THE DIFFERENCE BETWEEN LETTERPRESS, OFFSET AND ROTOGRAVURE

    In letterpress printing, now outdated, are used movable type to direct impression on the paper, the characters are returned with the edges marked by offering a total of three-dimensional effect. Offset printing is an indirect impression, with the use of aluminum alloy plates engraved, today, with laser heads (light or heat) which collect ink in the positive area and collect water in the unprinted part, the result is a character from dimensional effect. The rotogravure printing instead of using hollow slabs that absorb ink, where there is the character to be printed, the result is little defined with a low definition of the finer characters.
