L
Laminate Any protective, transparent material applied to either side of a print. Available in many
thicknesses (1.5 mil to 10 mil), finishes (gloss, lustre, matte), with anti-graffiti treatments and
scratch resistance. Laminates with heat-activated adhesives are known as hot laminates.
Pressure activated laminates are known as cold laminates.
Laminate Bead When the top and bottom laminates extend past the edge of a print, they form a bond that
seals out dirt and moisture. This aids in outdoor durability. Proper temperature and pressure
is required for an even, permanent seal.
Lay-Flatness The ability of a self-adhesive laminate to remain flat under changing temperature/
humidity conditions.
Lightfast The ability to withstand a predetermined amount of light with minimal or acceptable change.
M
Migration The movement of one or more components from one material into another. (e.g. plasticizer
from film to ink, plasticizer from film to adhesive, etc.)
Mottle Random blotchy irregular pattern in solid fill areas giving loss of density.
Mounting The process of adhering a digital print to a substrate using an adhesive, either on the back
of the laminated print or coating the substrate.
N
Nip The gap between the heat or pressure rollers of a laminator.
Normal Observer Person whose visual acuity and color perception fall within normal limits.
O
Opacity The degree to which a material can prevent the transmission of light.
Overlaminate Typically a pressure sensitive (cold) laminate that is applied on top of a finished print
(usually vinyl) to add durability, special finishes, increased thickness or other characteristic.
Over saturation Excessive amount of ink placed onto media causing image to bleed through to the backside
of the media.
P
plasticizer Component of plastic materials that provide flexibility.
