How to Create White Spot Data in Illustrator
Introduction
This section explains how to prepare images that include white spot data with vector-
based image editing applications such as Adobe Illustrator®. In order to print with white
ink, you must first have a media properly configured for the use of white spot data (
‘How
to Configure ProductionHouse for White Ink’ on page 146 ). This media model will include
at least one layer configured as a white spot color.
To add spot color data to your image in Illustrator, you need to create one layer within
the image as a new spot channel. It is possible to have more than one spot element in an
image, but each element must be on the same spot channel, and therefore have the same
opacity level, or else ProductionHouse will treat the saved document as a separation file.
CMYK is the preferred mode as the actions required for spot data creation are simpler
than those for RGB.
Note:
You can use vector-based image editing applications other than Illustrator as long as it
has the Overprint feature and the ability to create a spot color.
When to do
The first step in the white ink workflow is to prepare your source image to use the white
ink channel. The white ink data must be designed entirely on a separate channel (either
as a spot channel layer or a custom spot color) to be recognized by the Onyx RIP. The
name you assign to this spot channel layer or custom spot color must be “Spot 1” and is
the most important part of preparing the file. This named channel allows RIP-Queue to
determine that the data in the source image needs to be output to the spot channel, in
this case the white ink channel.
In preparing your file, only you can define what you want to print with “white ink” as
part of your design and assign the color as described in this document. In Illustrator, the
white ink data can be simple or complex and can range from vector shapes and text to
placed bitmap images.
How to Prepare an Image in Adobe Illustrator
Use the following steps to configure an Adobe Illustrator file for use with white ink:
1.
In Illustrator, ensure that the Swatches tab is visible (under the Window menu click
Swatches to view).
2.
Click the arrow on the Swatches tab to display the Swatches menu.
3.
Select New Swatch from the Swatches menu to open the Add Swatch dialog.
