♦ Print Area applies Backing White foil to the area within a bounding box that
surrounds all print shapes. Cut vinyl shapes are not included. In the example, the
square represents the bounding box of the print shapes and defines the Print Area.
Included are print and cut-only objects, Print Area extends beyond the printed shapes
and yields undesirable results.
♦ Job Area applies Backing White foil all the way to the boundaries of the job including
all print and cut shapes.
Applying Backing White to Clear Fills and Strokes
Turn on Apply to Clear Fills/Strokes to apply Backing White foil to any clear strokes or fills.
Turn off this option so Backing White is not applied to clear objects, allowing the vinyl to show
through.
When paneling or repeating jobs in GSPPlot, the print boundaries of the job are used to
determine the size of the printed job. Normally clear strokes or fills are not included in the print
boundaries since they are not printed. Applying Backing White to clear strokes and fills makes
the clear objects become print objects and boundaries may change. Before recalculating print
boundaries, GSPPlot displays a warning message. Choose Yes to allow the job to proceed.
Choosing No to return you to the GerberColor Backing and Finish dialog box where you may
alter the Backing White settings.
