How to Create White Spot Data in Illustrator
Create a box around your image using the Rectangle Tool or other appropriately shaped
1.
box tool.
Make sure this new box is selected and select Fill swatch located at the bottom of the Il-
2.
lustrator toolbar. This will fill the box with color. By double clicking on this swatch a
dialog box will open allowing for color changes. Ensure that the chosen color does not
appear anywhere in your image. For this example we have used red (composed of 100%
Cyan and 100% Yellow).
Place this rectangle behind your image data, either underneath or in a new layer below.
3.
It is not necessary to choose Overprint attributes for this layer.
