Overprint Spot Data In Illustrator - Canon Arizona 6100 XTHF Mark II Series User Manual

5. Use the new swatch for any objects which need to be printed with white ink. Create or select a
path and fill this path with your Spot 1 color. This filled path should be placed above image in
layers palette.
6. Save the file.
NOTE
In testing, we have found the .eps file format to be the best. However, Postscript and
PDF files will work as well, but may require some additional setup. Make sure that
when you save the file, "Preserve Overprints" is enabled.

Set Up Overprint
By default, when you print opaque, overlapping colours, the top colour knocks out (cuts a hole) in
the area of colored image underneath. Overprinting prevents knockout and allows the colored
image data to print over top of the other colour being used, which in this case is white. You will
want to overprint when the artwork needs to be printed over top of white, usually if the substrate
material is non-white and therefore white is required to accurately render image data.
Procedure
1. Select the spot data object or objects that you want to overprint and place these above the image
data layer that you would like to print. Or if you want them on the same layer the spot data
objects should be in front of the image data.
2. In the Attributes panel, select Overprint Fill, Overprint Stroke, or both.
NOTE
While it is possible to set Overprint opacity levels less than 100%, ONYX Thrive
software only processes full opacity data. The opacity of regular knockout spot data
can be set as desired.
