Abstract
A wide format scanner moves a substrate to be scanned along a first axis and at a first predetermined speed, and moves a scanning head across the substrate obliquely with respect to the first axis at an angle and at a speed coordinated with the first predetermined speed so as to provide a scan trace perpendicular to the first axis.
Claims13
A scanner comprising:
- means for displacing a substrate to be scanned along a first axis and at a first speed;
- a scanning head having a linear scanning element operative to scan the substrate;
- means for moving said scanning head across the substrate obliquely with respect to the first axis at an angle and at a speed coordinated with the first speed so as to provide a scan trace across the substrate which is perpendicular to the first axis;
- and
- means for selectably orienting the linear scanning element relative to the first axis, thereby determining the scan resolution.
