■
A Flood Fill layer is like an autofill that is done by the printer, where white data fills
the entire bounding box (the rectangular area that defines the total perimeter) of the
image.
■
White Spot data can be defined in image editing applications such as Adobe Illustra-
tor® or with the Spot Layer tool in Onyx ProductionHouse.
All of these methods to create white ink output will be explored and explained in this
chapter.
White Ink Workflow Data Preparation
White ink print job output can be accomplished in a variety of ways depending on the
desired results and preferred working process. There are three primary methods and they
can be used either independently or all at the same time. The workflow options are:
Flood Fill Layer Configuration,
ProductionHouse’s Spot Layer Tool, and
White Spot Data Image Preparation.
Flood Fill Layer Configuration in an Onyx Media Model does not require any pre-rip
file preparation and is the easiest method of achieving white ink output. All that is required
is to set up the Layer Configuration to include a flood layer. Spot data cannot be processed
in this way, as functionality is limited to creating a flood layer, which encompasses the
bounding box (the outer border of the image) of the file being processed.
ProductionHouse’s Spot Layer Tool offers many options to process an image, and thus
allows various possible configuration choices. You can save these configurations as Filters
and place them in a Quick Set and this makes it possible to re-create with minimal effort
settings that are often used. All work with the ProductionHouse Spot Layer tool requires
a media with spot layers enabled in the layer options in order for it to work as expected.
White Spot Data Image Preparation requires that the white data be prepared in image
editing programs such as Adobe Illustrator® or PhotoShop®. You must use specific
naming conventions and image use protocols in order for the Onyx RIP-Queue software
to process the data as desired. This method may be the best choice if the desired white
ink spot data includes complicated selections or if data is being created for outsourcing.
A reasonable level of proficiency in these programs is recommended to use this technique.
All of these methods can also be used either alone or in conjunction with each other to
create the desired output results. For example, you may generate the spot layer information
for parts of an image in PhotoShop and then go on to specify a Flood Layer Configuration
in Production House. This can result in a Flood Layer and a Spot Layer followed by a
CMYK Layer. The spot data and the flood will occupy two layers of white density and
the CMYK image data can occupy the third layer. You can determine the print order of
these layers in ProductionHouse.
