What is Gravure, Rotogravure, Printing?
Gravure Printing works on the opposite concept of letterpress printing. With gravure printing, etched areas are the ones that will create impressions on the paper's surface. These areas are recessed into a metal plate to create tiny wells. These collect ink when an inked roller passes over them. The printing plate is covered with these wells which, depending on their depth and size, control the amount of ink transferred to the paper when pressed against the plate.
This process works well for photographs but the setup can be expensive. The costs become reasonable only when used in large print runs like those of magazines and newspapers. Either spot color or CMYK colors can be used with this printing process.
Rotogravure Printing is the same process but differs in that the paper comes from large rolls rather than sheets.
