In January 2005 we have installed a Printflow DC solution at AMOS printing company in Prague. The Printflow DC together with the RS 400 scanning densitometer from Techkon enables a closed-loop density control of their Heidelberg Speedmaster 74 printing machine. The Heidelberg machine has been CIP3/4 integrated with a Creo prepress technology through a Printflow DIPSonline system too.
