Abstract
A printing apparatus includes a head part, an encoder, a tension sensor, a head part temperature sensor, an edge sensor, an estimation part, a storage, and an output part. The estimation part estimates print quality in terms of a page printed by the head part on the basis of variation elements detected by the encoder, the tension sensor, the head part temperature sensor, and the edge sensor. The storage stores print quality information containing the printed page and the print quality estimated by the estimation part in association with each other. The output part outputs the print quality information to a display, a post-processing device, and a printer controller section.
Claims9
A printing apparatus comprising:
- a transport part that transports an elongated strip-shaped base material in a transport direction;
- a head part that makes a print in terms of a predetermined print unit by ejecting ink to said base material transported by said transport part;
- a first detector that detects at least one of variation in a temperature at said head part, variation in the transport speed of said base material, variation in tension applied to said base material, and variation in the position of said base material as viewed in a width direction perpendicular to said transport direction;
- an estimation part that estimates print quality in terms of said print unit printed by said head part on the basis of a variation element detected by said first detector;
- a storage that stores print quality information containing said print unit and said print quality estimated by said estimation part in association with each other;
- and
- an output part that outputs said print quality information.
A printing apparatus comprising:
- a transport part that transports an elongated strip-shaped base material in a transport direction;
- a head part that makes a print in terms of a predetermined print unit by ejecting ink to said base material transported by said transport part;
- a drying part that dries ink adhering to said base material at a position downstream from said head part in said transport direction;
- a second detector that detects variation in a temperature at said drying part;
- an estimation part that estimates print quality in terms of said print unit printed by said head part on the basis of a variation element detected by said second detector;
- a storage that stores print quality information containing said print unit and said print quality estimated by said estimation part in association with each other;
- and
- an output part that outputs said print quality information.
A printing method comprising the steps of:
- (a) transporting an elongated strip-shaped base material in a transport direction;
- (b) making a print in terms of a predetermined print unit by causing a head part to eject ink to said base material transported by said step (a);
- (c) detecting at least one of variation in a temperature at said head part, variation in the transport speed of said base material, variation in tension applied to said base material, and variation in the position of said base material as viewed in a width direction perpendicular to said transport direction;
- (d) estimating print quality in terms of said print unit printed by said step (b) on the basis of a variation element detected by said step (c);
- (e) storing print quality information containing said print unit and said print quality estimated by said step (d) in association with each other;
- and
- (f) outputting said print quality information.
