Varnish Workflow Overview
Printer Flood Fill Layer Configuration in an Onyx Media Model does not require any
pre-rip file preparation and is the easiest method of achieving varnish output. All that is
required is to set up the Print Mode to use a Varnish Flood. The printer flood encompasses
the bounding box (the outer border of the image) of the file being processed.
ONYX Software 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 Spot Layer tool requires a media with two
spot layers enabled in the layer options in order for it to work as expected.
White Spot Data Image Preparation requires that the varnish data be prepared in image
editing programs such as Adobe Illustrator®, InDesign, 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
varnish 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.
Preparation for Varnish
The application of Varnish to a print produces some spectacular, and at times, surprising
results depending of the combination of design and media. To achieve a smooth high
gloss, varnish must be applied in heavy coats. To achieve good results consider the follow-
ing influences and tools.
• Environmental Contaminants
In the printer operating environment the amount of airborne particles can influence
the final varnish finish. Since the systems that condition and circulate the air can also
circulate dust and particles, keeping the printer clean enough to produce good gloss
varnish finish may require extra cleaning. If you use the Varnish option frequently,
we recommend that you take steps to minimize contaminants by isolating the printer
from dusty conditions.
• Surface Preparation
The surface of the media must be free from dust and dirt particles. With the media
loaded on the table, it is recommended that you gently and completely wipe the surface
with a Lint Free cloth or a Tack Cloth.
• Cleaning Tools
Tack Cloths are a highly effective tool for trapping and removing dust and dirt particles
from most surfaces. They can be purchased at various stores that offer paint and sup-
plies. It is best to attach a Tack Cloth to a flat object and let it lightly rest on the media
while it is wiped.
Electrostatic Cleaning Devices can be used with a Tack Cloth attached to wipe the
surface and and will reduce static charges that attract more dust. The long handle allows
access to the media across the entire printer table. Lint Free Cloths can also be used.
