Adding Cutlines to Artwork
"white." In some cases, a background area of an image that appears white to the eye may
actually be gray or off-white, so you might get a cut line or clipping path around that area. The
White Threshold allows you to control the balance between "white" and "non-white" colors.
To add a cut line, clipping path, or both to an image
1 In Composer, select an image with either the Selection or Color Selection pointer.
2 Click Tools > Generate Decal Cut to open the Decal Cut dialog box.
3 Choose Cut Only, Clipping Path Only, or Both.
4 Adjust the White Threshold to set how many colors are interpreted as "white" or "non-
white."
5 Click OK. The decal cut results are placed directly on top of the originals as cut only,
clipping path, or both a clipping path and a cut shape. The decal cut results are
grouped, making it easier to isolate them.
6 Once decal cut results are generated, you can:
♦
Delete the results, adjust the White Threshold setting, and regenerate a decal cut
or clipping path.
♦
Use the Detail Edit Smooth tool or use Shape > Thin to reduce the points and
make the decal cut results less jagged.
♦
Remove any extraneous cut lines or clipping paths using Ctrl+click to select
individual shapes and delete them.
♦
Use Tools > Outline with a positive offset value and Keep Originals off to create
a gap between the print objects and decal cut.
♦
Use Tools > Outline with a negative offset value and Keep Originals off to create
a cut line that is slightly smaller than the print objects to reduce print to cut
registration gaps between the print objects and decal cut results.
