“Print only” Overlap Registration System™
More Than One Way
Contra Vision® Impress™
Why Contra Vision® Impress™
Contra Vision® Impress™ and Contra Vision® BACKLITE
Impress™ are see-through window graphics products
on non-perforated transparent material such as selfadhesive PVC or polyester film. They have superimposed
layers of ink in a print pattern, for example of lines,
leaving transparent gaps for through vision.
The Overlap Registration System™ has many advantages
over perforated vinyl systems, including the greater
durability of a non-perforated substrate, typically
print-treated polyester or PVC films or sheet plastic.
The printer has total control over key factImpress such
as substrate selection, percentage transparency, print
pattern and the ability to emphasise a particular part of
a design, for example by “blocking out” a logo and its
background layer within a see-through advertisement.
10 Configurations
There are 10 different configurations of see-through
graphics related to:
• opaque or translucent print patterns
• outside or inside application
• one or two printed designs or a projected design
Overlap Registration System™
Normal registration error in any printing method will
lead to unwanted visual effects unless special measures
are taken.
The Overlap Registration System™ is a patented system
of managing the inevitable lack of registration in any
printing system to provide see-through graphic panels
of reliable colour rendering and the desired visual
perception of the image.

Contra Vision® BACKLITE Impress™
Conventional see-through graphics, with a black layer,
whether perforated or non-perforated, lose impact
during the hours of darkness with internal illumination,
for example inside a retail outlet or bus. When panels
are required to be visible at night, this is where Contra
Vision® BACKLITE Impress™ products come into their
own. Contra Vision® BACKLITE Impress™ products
typically comprise a design superimposed on a pattern
of translucent white lines with no black layer.

see-through advertisements are
economic and proven in
hundreds of advertising
campaigns
These panels typically have a design visible on one side
and a ‘ghost’ reverse image seen from the other side.
Both sides will allow vision through the transparent gaps
between the lines as the human brain can choose to
focus on either the design or the other side of the panel.
Thus a customer in a retail outlet can see through a
Contra Vision® BACKLITE Impress™ panel on a window
to outside. Normal internal lighting is enough to ensure
the image is visible from outside during darkness but, for
added impact, interior lighting can be supplemented,
for example by ceiling-mounted spotlights, to make the
advertisement stand out.
Transparency control
The transparency of see-through graphics is determined
by the width and spacing of the printed lines.
Graphics have greater impact with lower transparency.
See-through characteristics are better with
higher transparency.
Contra Vision® Impress™ allows total control over
the transparency of see-though graphics.
You can even selectively block areas out to be solid.

blocking
The required know-how is available free to Contra Vision
licensees, which explains how to create the print pattern and
artwork for each layer of the Overlap Registration System™
using a vectorial software system such as Adobe® Illustrator®
or Adobe® InDesign®. UV inkjet flatbed machines, such as
the Inca Spyder 320, build up the required layers in stages
whereas machines, such as the Dainippon 2500 or HP Indigo
can print all required layers in one pass of the substrate.
Screen, litho and flexo printing equipment can also be used
for larger volume orders.
Printers can now become licensed online, in any country, to
practise this patented system using any printing equipment.
Contra Vision has a unique understanding of see-through
window graphics. We started the industry in 1985. We have
invented and own the patents and other Intellectual Property
for the widest range of see-through graphics technology, a
portfolio of 25 inventions patented or patent-pending.
