Optimizing the print registration of black
If color-to-color print registration is critical, you can optimize the print registration of black in a
job with the CMYK Black check box in the GSPPlot Print Options dialog box. For example, if the
job has spot colors with black butting against other colors, occasionally there may be a small
seam of unprinted vinyl, which allows the vinyl color to show through. If you change the spot
colors to process colors and turn on the CMYK Black check box, black is printed with all four
process colors and registration problems are reduced.
To optimize the print registration of black
1 Turn on Print as Process in the Print Options dialog box in GSPPlot to convert the job
to a process color job.
2 Turn on CMYK Black. Black is printed with all four process colors.
Tip: When you use this printing option, you will use slightly more process foil and the edge of the
black shape may not be quite as sharp as spot color − however color-to-color registration is
improved.
Refining color registration when using GerberColor Spectratone colors
Occasionally when printing GerberColor Spectratone colors, the bottom (base) color may show
as a halo around the top color. To reduce the bottom layer of the Spectratone color, you can
change the base color size by shrinking it with the Shrink Base check box in the GSPPlot Print
Options dialog box.
To refine a Spectratone color job
1 Turn on Shrink Base in the Print Options dialog box.
2 Enter the value to reduce the base size in the Shrink Base text box.
Tip: The perimeter of the base color shape is reduced by half the value you enter in the text box.
