Create Spot Data with the Spot Layer Tool
Introduction
The Spot Layer Tool can be used to set up two spot data planes that define areas where Spot 1
and Spot 2 data are added to a print job. The tool is used with the Arizona printers that both have
two extra channels to provide varnish or white ink as well as with CMYK only printers. Both white
ink and varnish can be printed using either Spot 1 or Spot 2 data. The same spot data can be used
to print either white ink, varnish, or both.
NOTE
Varnish is not supported for the Arizona 135 GT.
In this section, you’ll learn how to access and set up the Spot Layer Tool. The tool provides a
variety of options for generation of spot layers, and you may want to explore them with a sample
file of your own to familiarise yourself with the functionality. Remember that any actions you set
for this tool will only work successfully when used in conjunction with properly constructed
layers. The tool is located in Preflight on the Colour Correction tab.
The Spot Layer Tool provides options for generating spot layers for your image in ONYX Thrive
rather than in image editing programs such as Illustrator or Photoshop. The tool has many
advanced options and this section will explain them so that you can set them up to best achieve
your desired results. The tool options and settings to use it for spot data creation are listed here
and are followed by instructions to access the tool.
How to Use the Spot Layer Tool
The Spot Layer Tool Provides These Options:
Generation Options - Set Media
Set media colour is optional and serves two purposes:
• If you want to preview the media colour in Preflight, you can set the media colour either from
the image or from the colour dialogue menu.
• If you have areas in your image that use the media colour and you want that colour to be
handled with special consideration. For example; if you want the media colour from the image
to show through the design, you must first define your fill options, then set the media colour
and define the Media Colour Handling Options as either "Spot Knockout" or "Full Knockout".
NOTE
The generation options are used in combination with the fill options, except when the media
colour handling is set to "No Knockout". If you want to use the Spot Layer Tool to create flood
fills, underlay fills or mask fills it is not always necessary to set a mask or media colour to get the
desired results.
To set the media colour: Click the sample box to activate the colour picker or use the drop down
arrow to access the Colour Dialogue menu.
Generation Options - Set Mask
The mask allows you to determine the area that you wish to print with spot data. Setting the
mask colour is optional. If the image you are printing contains white data in more than the mask
area, you will need to set up a different background colour not used anywhere else in the file to
use as your mask. This must be done in an image-editing program prior to bringing the image
into the Spot Layer Tool.
To set the mask colour: Click the sample box to activate the colour picker or use the drop-down
arrow to pick the colour from the preview.
