Printing a Job on a Vinyl Printer
Applying a white undercoat (Backing White)
Printing process or spot colors on clear or colored vinyl may alter the appearance of the foils. To
maintain the intended colors, apply a white undercoat (Backing White) to the print area. The
white foil serves as a barrier between the vinyl and the foil producing truer color. When
printing on a clear substrate, Backing White provides a solid background for the foils and
eliminates translucency.
Add Backing White to a job through the Print Options dialog box of GSPPlot. Click
Backing/Finish to open the GerberColor Backing and Finish dialog box. If you are working
with layers, the Backing/Finish settings apply to the entire job.
As the default setting, Backing White is applied to process colors only. Turn off Process Color
Only to apply Backing White to both spot and process foils.
Note: The Backing White option uses GerberColor Spot Color foil White GCS-10 to print the
white undercoat. White GCS-10 is qualified to print at 300 x 300 DPI Print Mode only. Set
your Print Mode to 300 X 300 DPI when printing Backing White using an EDGE 2, EDGE
FX.
Choosing the method of application
There are several ways to apply Backing White to a job:
♦ Print Shapes applies Backing White to individual shapes in the job. The example
includes print and cut-only objects, Print Shapes applies Backing White behind the
printed oval but not behind the cut-only text Cliff County Firehouse.
