1. True/False: Process inks use or- False
ganic pigments to provide the
transparency necessary for build-
ing colors.
2. True/False: Monomers are the sol- False
vent component of UV ink that
evaporates when exposed to in-
tense UV radiation.
3. True/False: Colbalt is an additive True
that acts as a catalyst to speed
up how quickly a lithographic ink
sets.
4. True/False: As the pH goes up, True
the viscosity of water-based flex-
ographic ink decreases.
5. True/False: Surfactants are addi- False
tives designed to reduce the co-
efficient of friction of the printed Surfactants are organic chemicals added to an offset press
product. fountain solution to reduce the surface tension of the
solution and to better allow it to quickly wet the rollers and
the plate.
6. True/False: A coated offset paper False
is naturally stronger than an un-
coated offset paper of the same
weight due to the clay fillers in the
coating.

True/False: After chemical pulp-
ing, beating the cellulose fibers
flattens them and causes them to
fray of fibrillate, making stronger
papers.
8. True/False: Hydrogen peroxide is True
a bleaching agent that is more en-
vironmentally friendly than chlo-
rine.
9. True/False: Chromatic adaptation True
refers to how our brains seek a
reference color (usually white or a
neutral) to interpret other colors.
10. True/False: Rods are the color dis- False
criminating receptors in our eyes.
Rods are small light-sensitive sensory cells on the retina of
the eye. Rods are sensitive to differences in light intensity
but CANNOT distinguish colors.
