White Ink Workflow Overview
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.
White Ink Applications
The following are some specific examples of the ways that the white ink workflow can be applied.
• Backlit Application
The backlit application involves printing onto a transparent or translucent material and
mounting the finished piece onto a light box or location where illumination from behind is
possible. In the backlit application, white ink is intended to provide a light diffusing layer. This
application is possible using either 2 or 3 layers.
• Day-Night Application
Similar to backlit, the day-night application also involves printing onto a transparent or
translucent material. A day-night print can be viewed either front-lit or backlit. This is achieved
by printing color data on two separate layers with a white diffusing layer in the middle.
• Opaque Application
The opaque application involves printing CMYK data onto non-white media. For this
application, white ink is required both to enable the printer to produce images where white
forms part of the image content, as well as to act as a base for the CMYK color set.
