First of all, by printing in an extended gamut, most job changes do not require a color change. However, should a color change be required, this does not take long on offset systems like the Contiweb Thallo. Converters need only change two sleeves – the plate sleeve, and the blanket sleeve. This can be done in just two minutes per printing unit. Largely, the length of a job change is determined by the number of color changes. The Thallo has an automatic washing option that washes all the print rollers inside each unit in just five minutes.
