ABSTRACT:
A method is described for producing a multicolor printed web material such as a carpet substantially without spoilage of production web material during a start-up of a printing process employing a plurality of dyes applied in different patterns. A lead carpet is formed which is non-receptive to the dyes. The lead carpet is attached to the production carpet and the dye patterns tested on the lead carpet. After correction, if necessary, for print misalignments and other dye printing station operations, the production carpet is printed. Both lead and production carpets are processed to fix the dyes and remove excess non-fixed dyes. The removal step results in cleaning of the lead carpet on which the dyes were not fixed. The lead carpet is then disconnected and made available for another print start-up.
