Glossary of Terms
A _______________________________________________________________
3-Colour black Area of solid Cyan, Magenta, and Yellow combining to form a black.
Accelerated Light Testing Equipment is used to expose materials to light, at elevated energy levels,
more concentrated then the actual light source.
Adhesion Bond between two surfaces. A substance capable of holding materials together
by surface attachment
Adhesion, Initial Force required to remove a pressure sensitive material from a substrate
(Important: this force can only be measured under specific, standard
conditions to obtain reliable and comparable results.)
Adhesion, Peel Peel adhesion, measured 20 minutes after the self-adhesive material has been
applied.
Adhesion, Ultimate Peel adhesion, measured 24 hours after application of the material
Adhesive Permanent Adhesive that provides permanent bond to a wide variety of surfaces
Adhesive Removable Adhesive giving low ultimate adhesion to a variety of surfaces
Adhesive Repositionable Adhesive that permits removal and re-positioning shortly after application,
prior to development of ultimate adhesion.
Application A method for creating a graphic for a specific purpose. This can include
materials, printing, finishing and construction methods.
B ______________________________________________________________
Backlit A print illuminated from behind. These prints may also be viewed from the
front with the back lighting off.
Bleed Amount an image extends past the desired size of a print. This extra image
area allows for errors in sizing and positioning during finishing. External bleed
is measure outside the final trim dimension of the print. An external bleed of
0.5" will create a print 1" larger than required. Internal bleeds is the amount
an individual panel extends over a seam between panels. An internal bleed of
10mm will give 20mm overlap between adjacent panels
Boat-waking During lamination, uneven tension can cause ripples in the prints. Boat waking is
when ripples originating at the center of the print extend diagonally out towards
the edges.
C ______________________________________________________________
Calendered PVC PVC (poly vinyl chloride) sheet formed by means of system of cylinders,
distributing and pressing the PVC into a sheet of the required caliper.
Caliper Distance between the 2 surfaces of a material, measured in microns.
Cast Coated PVC PVC sheet manufactured by coating PVC onto a web of coated paper. This
technique allows the production of PVC sheeting with low caliper, high
flexibility and improved dimensional stability.
Chemical Resistance The resistance of a material to the deterioration effects resulting from
exposure to chemicals under specified conditions
Cohesive Strength The internal strength of an adhesive, often determined by the force required
to split or separate it internally.
Conformability Ability of a material to adjust itself to the contours of a surface.
Curl Tendency of a paper or laminate to bend around the axis of one of its main
directions.
Cyan, magenta, yellow The subtractive (process) primaries
