If there are issues applying varnish to particular media, try printing on a suitable alternative
media.
With its translucent property, varnish can increase or shift the apparent density of the image or
media, so for instance it can make a gray slate darker in the areas with varnish.
It is important to clean media before printing and to remove any dust or debris from the media
surface. Also, to eliminate any static charge on the media prior to printing, use the optional
printer Static Suppression Option (ionizer bar) to eliminate static.
Some media can be purchased with a top protective sheet that is removed prior to printing.
However, the act of removing the protective sheet can induce a static charge and attract airborne
dust to the media surface. Based on our experience, there is little benefit in trying to clean the
media after printing the image data and prior to printing the varnish.
The surface of the media must be free from dust and dirt particles. With the media loaded on the
table, we recommend that you gently and completely wipe the surface with a lint-free cloth or a
Tack Cloth.
There are various methods employed in print shops to clean media prior to printing and these
include:
• Tack cloth and Cleaning wands (floor cleaning style);
• Mix of 99.6% or higher pure isopropyl alcohol and distilled water.
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 supplies. It is best to attach
a Tack Cloth to a flat object and let it lightly rest on the media while it is wiped.
