A series of usually flat platforms of open construction stacked or hinged one over the other on which printed sheets may be placed for air drying at ambient temperature.
Language and our ideas about how it is interpreted change rapidly. The Specialty Graphic Imaging Association (SGIA) is aware of this and continues its effort to keep our constituents well informed about changes to the increasingly complex industry terminology. This publication represents the most recent changes.

(1) A line segment joining the center of a circle with any point on its circumference; (2) A measure of the curve or range on which a printing screen travels in printing tapered objects; (3) Measure of the curve on which artwork is distorted to fit a curved or tapered surface of a bottle or cylindrical object.
The technique of screen printing on conical shapes, where the printing screen moves along the arc of a circle while the squeegee remains stationary.
