Rotogravure presses for publication run at 45 feet (14 m) per second and more, with paper reel widths of over 10 feet (3 m), enabling an eight-unit press to print about seven million four-color pages per hour. The vast majority of gravure presses print on rolls (also known as webs) of paper or other substrates, rather than sheets. (Sheetfed ...
Today, there are four main types of rotary presses; letterpress, offset (including web offset), rotogravure, and flexo (short for flexography). Although all the types use cylinders to print, they vary in their method. Rotary letterpress printing uses type metal plates molded in the form of a cylinder.
A method of full-color printing is six-color process printing (for example, Pantone's Hexachrome system) which adds orange and green to the traditional CMYK inks for a larger and more vibrant gamut, or color range. However, such alternate color systems still rely on color separation, halftoning and lithography to produce printed images.
When the two colors are process colors, the trap contains the highest value of each of the CMYK components. This trap color is always darker than the two abutting colors. In some cases, more specifically when the two colors are pastel-like colors, this might result in a trap that is perceived as too visible. In this case, reducing the amount of ...

Other colors, regardless of their relative luminance, are always trapped to (spread under) these spot colors. If several of these spot colors are used (a common practice in the packaging market), the order of printing layers rather than luminance is the decisive element: the first color to be printed is spread under the next color.
