Varnish Workflow Overview

Varnish Workflow Overview
Introduction
Océ Arizona printers with the Varnish Option can overprint varnish on top
of a printed image in select areas in a print job or as a flood coat. The
printing of varnish applies only to flatbed printing and is not available with
the RMO.
NOTE
The Varnish option is not available for print jobs that use the High
Definition print mode. Varnish can be used with all other print modes.
Printing varnish creates a high value-added special effect. However, since
this is an additional process after printing image data, it also decreases
productivity. Due to the low productivity of printing large areas of varnish,
it is best to concentrate the use of this feature on spot decoration.
Fortunately, the Arizona printer "blank space" skipping feature skips over
areas in the print that do not contain varnish, and greatly improves the net
productivity of spot applications.
Varnish is printed as a second process after the CMYKW image is printed.
Immediately after printing a CMYKW image. The gantry moves to the start
of image position and prints a varnish spot or printer generated flood data
using three additional passes.
NOTE
Varnish is actually "clear ink" and is for decorative purposes only. It does
not provide additional protection to the printed image.
Spot Versus Printer Flood Fill
Varnish data can be applied to a print job in two ways: Printer Flood Fill or
Spot Data.
• A Printer Flood Fill is like an auto-fill that is done by the printer, where
varnish data fills the entire bounding box (the rectangular area that
defines the total perimeter) of the image.
• Varnish Spot data can be defined in image editing applications such as
Adobe Illustrator® or with the Spot Layer tool in the ONYX workflow.
The Spot Data can be defined as either Spot 1 or Spot 2. The same spot
data can be used to print either varnish or white ink, or both.
