Choosing the right paper for a printing job is a very
complicated undertaking. It should not be that way though. You
have overwhelming options. All you have to do is to be specific.
Paper influences all the aspects of a print project, together
with overall perception, reproduction quality, durability and
mailing cost. Choose defectively, and you can spoil an otherwise
great project.
To be specific is to consider a lot of aspects. First the
surface of the paper because it affects its look, feel and
printability. It matters because people are influenced by the
appearance of the paper, it’s that simple.
Second aspect is the paper color. Color is the most important
characteristic since it controls the hues and shades of the ink.
At present, white is the most popular color and is generally
optimal for conventional uses. Off-white paper produces fewer
glares. It is usually used in publications such as novels and
manuals.
Brightness is another aspect that needs to be considered. It
measures the percentage of light that it reflects. Most papers
reflect 60-90% of incoming light. It is important because it
affects readability. High level of brightness can cause eye
strain. Conversely, low brightness can cause blurring effect.
The fourth aspect is opacity. It is the degree to which other
printing is visible through the page. High level of opacity
minimizes the visibility of printing on succeeding pages, as a
result, it enhances readability. Opacity is influenced by the
other factors such as bulk and weight of paper, paper color, ink
color, coatings, chemicals and coverage.
Grain, on the other hand, describes the direction or alignment
of its component fibers. It is either grain short or grain long.
When fibers run parallel to the width it is grain short. Grain
direction determination is critical to paper strength,
flexibility, tack and versatility.
The basis of weight of paper is premeditated in pound of one
ream or five hundred sheets. Paper is sold by pound and
understanding paper weight is essential to a triumphant cost
control programs.
Caliper means thickness. It is measured in thousandths of an
inch and referred to as point size (.001 inch = 1 point).
The eighth aspect is the bulk. It denotes thickness relative to
its basis weight. Uncalendared paper will have a higher bulk
than gloss coated paper. Keep in mind though, that paper may be
bulkier or thicker than another grade but may still have the
same basis weight.
The size of the paper depicts its physical dimensions. Ask your
supplier for specific information concerning the range of paper
sizes to ensure proficient usage.
The tenth aspect is the paper quantity. It refers to the number
of sheets. A ream is equivalent to 500 sheets. Cartons of paper
are typically weighing 150 pounds.
In purchasing paper, work side by side with the supplier. Paper
suppliers can help you in picking the best paper in terms of
possible weight, texture, tear strength and color for the
printing surface. Always discuss your paper needs with your
paper supplier and your printer at the earliest possible
opportunity.
