摘要

Speed features heavily in modern print technologies, which seems to run against the traditional view of gravure. However, the industry is oriented towards progress. Current rotogravure presses run at 15.00m a second and, often times, even faster, with paper-reel widths of up to 4.32m. As with offset lithography, the gravure process is compatible with sheet-fed and web-fed presses, although the majority of presses are web-fed. Most gravure presses for publication have eight printing units, one for each of the four process colours (YMCK) on each side of the paper. Occasionally, a fifth printing unit is included - making it ten units in total - to allow a spot colour such as metallic or fluorescent inks for special effects.
