Basic Paper Primer
Paper weight is based on the basic size of a given paper as determined by a given mill. For this reason, many weight notations one finds has at least 2 separate numbers. This does not necessarily mean the weight fluctuates between the two. Generally with printers and suppliers is not a range, but a definition from more than one source and may include more than one grade of paper (bond, text, etc.). A 50/60# paper is ordered as 50# and as 60#. However, when put through standardized testing, it is found that each sheet carries the same weight. All specifics supplied If in doubt, check with the business presenting the number information for formal explanation. Gregath paper suppliers do recognize the standard variation in basis weight of + or – 5% as acceptable by industry standards.
Paper brightness affects the legibility and contrast of printing. The brightness test measures the reluctance of paper under strict optimal conditions and related it to a white standard (Magnesium Oxide). The test is mainly applicable to white paper grades. Basic offset grades are usually in the 80% brightness range. Aesthetic importance may also be given to the brighter papers. However, if archival quality is a focus, one must be certain that it is not traded for the brightness. White papers with 90+ brightness sometimes actually have a blue or colored cast due to additives.

Brightness: The brilliance or light-reflection characteristic of paper (not necessarily related to its color or whiteness).
Dimensional Stability: The degree to which paper retains its dimensions during applied stress or changes in moisture content.
Coated Paper: Paper is traditionally coated on two sides and is broadly used for all types of printing, included multicolor work. Lately, paper coated only on one side has become available and widely used as an economical measure.

Paper opacity is the lack of transparency that allows a sheet to conceal print on the opposite side. weight, brightness, type of fiber and filler in testing can all greatly influence opacity. Reflectance of paper is measured when backed successfully by a white body and a black body. The ratio of these two measurements determines the opacity reading. Typical opacity of 50# white offset is 88-90; 20# business paper is 84-88. A quick and very basic “home” test is to print something large and black (black and white clip art and or various sized of bolded text) on a sheet of paper, place a blank sheet of the paper to be tested over this printed sheet. Any print that happens to show through, will show a bit more if actually printed on the currently black paper. For book printing, take your darkest page and try this test. Many manuscript designers will change their manuscript elements to decrease the opacity needed for a nice book rather than pay the difference for higher opacity.

Most of the work Gregath Publishing Company does in-house is offset printed. We offset print on uncoated papers. Uncoated papers have been traditionally classified by weight. Interest has begun to increase also as to the brightness as well as archival nature. As publishers, we have selected as our basis paper one that balances all of these issues while taking into account economy as well. If a customer has a list of specifics, or even a particular brand/type of paper, we are happy to get paper mill quotes and pass the information on.
Gregath’s standard book paper is a #50/60 uncoated white paper, acid free with a brightness of 84% – long grain.
