UV coatings
are acrylic varnish cured instantly by ultraviolet lamps.
The primary application of this finish involves
a series of precisely controlled rollers with the applicator roller
directly touching the printed surface. Providing you with a very smooth,
high gloss finish.
In the case of spot "registered" UV
coating a polymer plate is used to apply the varnish registered to the
printed matter.
The spot UV varnish can be functional "glue areas or dealer stamps"
or decorative "precise register to highlight a printed area'.
Note: Today's UV coating stocks can be
repulped and therefore can be recycled. UV coatings are V.O.C. free
and are considered to be the best available technology for a surface
finish.

UV-Book
(High Gloss)
This is the most commonly requested UV finish. It is a general purpose
high gloss coating formulated for slip. UV-B offer benefits of a tactile
effect as well as additional slip for subsequent machine ability. This
finish should be considered for covers of magazines, brochures, annual
reports, greeting cards and catalogues, but not where further processing,
such as gluing, foil stamping, and imprinting is required.
UV-WEB
(High Gloss)
This
is a highly wettable, high gloss UV coating. It is formulated to flow
out and adhere to difficult border line inks. This higher cost UV coating
is usually used when the regular formula UV coatings will not adhere.
UV-M
(Matte)
Offers the same handling resistance and protective qualities of UV-B
but with highly readable non glare finish.

UV-Gloss
(Glueable)
A specially formulated high gloss coating that can be specified where
further processing, such as gluing, foil stamping or secondary printing
is required. This coating will maintain consistent wettability and will
register a consistent dyne level on the cured film surface as an aid
to further processing. Consult your Belmont professional for recommended
adhesives and foils used in conjunction with this finish.
Selecting
Paper or Stock
Substrates best suited for UV coating range in caliper from 60 LB paper
to 24 pt. board stock. It is very important that the stock have a sizing
or clay coated surface for the UV coating to set up on. Substrates without
these surfaces tend to absorb the UV coating and prevent the coating
from converting completely. UV coatings that are not fully converted
(cured) are not commercially acceptable.
