Abstract
Method, apparatus, and system are described wherein dot matrix characters are formed by an array of ink spray nozzles within a marker head assembly upon the inside surface of a pipe or other curved surface. The marker head is moved by a traversing arrangement including a carriage in a manner wherein full character pixels are formed during movement of the marker head along locii parallel with the longitudinal axis of the pipe being marked. This achieves full messages marking with a minimized number of required marker head movements along the inside surface. An indexing mechanism engages the outer surface of the pipe to index it from one marking locus to a next. A translational mechanism moves the marker head traversing mechanism from off-line to on-line positions at the production path during the course of operation of the system.
