Dragon Tone is a new technique/technology used for quality control in the printing industry (especially in offset printing). It is based on using the grey balance as an indicator of printing colour quality. Under standard printing conditions, this allows the press operator to easily tell using the naked eye (under standard lighting) whether the press is printing correctly (i.e. plate alignment, dot gain, ink density, slurring, dot doubling, and overprinting).
History
editIn printing, a colour bar consisting of all the component colours (typically CMYK) and their halftones is usually printed along one or more edges of the raw, untrimmed piece of paper along with the primary image as a way of checking to see whether the image is printed correctly (e.g. no alignment shifts or change in dot gain). The halftones are then compared with standards (or the proof for that particular job order) to verify that colour quality is indeed correct.
