ABSTRACT:
A circuit pattern printing system includes alignment apparatus (71) which is located remote from a printer (35). The alignment apparatus includes a means for displaying a cursor (69) on a video screen (101). The cursor identifies a desired position of a fiducial mark (61) printed on a substrate (106) when the substrate is positioned against a reference guide (86) on an alignment table (76). The cursor (69) and the reference guide (86) are aligned to each other by first aligning the reference guide (86) to an alignment marker on a standards substrate (41), and then aligning the cursor to a fiducial mark located on the same standards substrate.
