Ink jet printer for photographic printing, has image sensor detecting paper path edges, and controller for applying digital mask to recently acquired image for vacuum support coverage control

摘要

The printer has drier (48) above non-vacuum support (31'') and paper cutter (59'') after second transport roller (28'). Measurement roller (18) is between transport rollers (16,28'), with rear side printer (26), vacuum paper support (31') and non-vacuum paper support between measurement and second transport rollers. Color ink jet head (36) is above vacuum paper support. Image sensor (46) detects edges of paper path. Controller (54) applies digital mask corresponding to edges.
