Prepare A File For The Spot Layer Tool - Canon Arizona 6100 XTHF Mark II Series User Manual

Prepare a File for the Spot Layer Tool

• Mask Fill Opacity
This option generates a fill in the selected spot channel where mask data exists. The fill will be
generated anywhere the image data matches the mask color.
• Choke and Spread
Choke reduces the outer edge of the underlay. Use choke when you want to eliminate white
from peeking out of the edge of your image. Spread increases the outer edge of the underlay
fill. Use spread when you want a deliberate halo around the edge of your image. Choke and
Spread work in tandem. Each mark on the slider represents 1 pixel width of choke or spread up
to 10 pixels (+-) .The actual preview in the Job Editor is exaggerated from what is printed. This
exaggerated display makes it easier for you to see the results from moving the slider. When
you use the Spot Layer Tool for masks, we recommend a choke value of 3 ticks.
• Diffuse Edge
Use this option when you want a gradual transition from the underlay to the mask to create a
soft edge for the fill. We do not recommend use of this option.
• Filter
Once you've defined your settings, save them by exporting a Filter to use on similar jobs.
Filters are a global color correction that can be applied to Quick Sets to automate the printing
process for multiple jobs that use the same settings.

NOTE
The Spot Layer Tool in ONYX Thrive can also make masks for data, and in some cases may be
the preferred method of spot layer creation. To ensure that mask selection is made without
selecting those parts of your image that are of the same color, it is necessary to create a layer in
Illustrator to serve as the mask.
Procedure
1. Create a box around your image using the Rectangle Tool or other appropriately shaped box tool.
2. Fill the box with a color that does not appear anywhere in your image. For this example we have
used red (composed of 100% Magenta and 100% Yellow).
3. Place this rectangle behind your image data, either underneath or in a new layer below. It is not
necessary to choose Overprint attributes for this layer.
Result
The prepared file should look similar to the example below.

Job Editor, if desired.
