Paper Specifications
Printing paper comes in a wide variety
of finishes, weights and colors. These qualities combine to determine
which paper stock is best for your project. At Edward Hine Company,
we use our experience and the knowledge from our network of paper
suppliers to show you the best options. Whether you’re looking
for high quality or low cost, we’re here to answer any paper
questions you may have.
Uncoated and coated paper
have different surface textures. In the papermaking process, uncoated
stock has been compressed between metal rollers to a limited degree,
yielding vellum, antique, wove and smooth surfaces (from rough to
smooth, depending on the amount of compression). Coated paper varies
from roughest (matte) to smoother (dull) to smoothest (gloss), also
depending on the amount of compression. Paper can also have such textures
as "linen" and "canvas" pressed into the surface.
Generally, the smoother the surface, the better holdout a sheet has
(the better the ink sits on the surface of the paper rather than being
absorbed into the fibers). M
Weight is based on the physical
weight of 1000 sheets of paper. For example, 1000 sheets of 80#
cover, measured at 20" x 26", weighs 160 pounds. The same
paper in text weight still weighs 160 pounds but the sheet size
is larger at 25" x 38", making it a thinner sheet. Most
paper weights in printing fall into the areas of bond (lightest
weights), text (light to medium weights) and cover (heaviest weights).
Brightness
refers to the amount of light a sheet reflects (0 to 100 percent).
The brightest sheets often measure 96 and above. Whiteness
refers to the color of the reflected light (either yellow-white
or blue-white, i.e., warm or cool). Brightness and whiteness affect
readability (too much light tires your eyes when reading long blocks
of text) and the crispness of photos (too little light reflected
back makes photos seem dark or muddy).
Opacity
determines show-through. A sheet with high opacity will prevent
solids, screens and halftones from being visible through the opposite
side of the sheet. Colored sheets are usually more opaque than white
sheets. This quality is rated on a 1 to 100 scale. Most sheets fall
in the 80 to high 90 range.
