Abstract
A printing system having a registration system for use with a variety of different types of media. The printing system is suitable for use with labels (with gaps or I-marks), continuous plastic (with I-marks), and bags (with perforations). The printing system includes a system for registering perforations (30) including a vacuum probe (34), vacuum sensor (36) and detection circuitry (38) to detect perforations. The printing system also includes a system for registering contrasting I-marks (10) appearing on a transparent media.
Claims16
A system for registering perforations formed in a sheet media, comprising:
- vacuum generation means for generating a vacuum;
- sensing means for sensing a vacuum level;
- media advancement means for advancing the sheet media across the sensing means;
- and
- detection means for receiving the vacuum level from the sensing means and detecting the presence of a perforation when the vacuum level reaches a predetermined threshold level.
A method for registering perforations in a printing system comprising:
- advancing a sheet media through the printing system;
- generating a vacuum to draw the sheet media to form a seal, wherein said sheet media includes at least one perforation;
- continuously sensing a vacuum level as the sheet media advances through the printing system;
- and
- detecting the at least one perforation in accordance with the sensed vacuum level.
A method for registering a contrasting mark formed on a generally transparent sheet media as the sheet media moves through a printing system, the method comprising:
- sensing the transmittancy of the sheet media;
- advancing the sheet media through the printing system;
- detecting a contrasting mark in accordance with the sensed transmittancy of the sheet media, and
- registering the contrasting mark in response thereto.
