A Little About Archival Quality

Internal Factors

  • Binding

The various binding processes that are employed take the same care to negate acidity as the care of paper selection noted above.

External Factors – Production

  • Gregath Printing Facility

Our printing plant is in a rural area with low air pollution.  While we are not a “white glove” facility, our employees are kept to a “clean hands” policy, which minimizes the amount of oils on the skin (guarding against acid transfer), as well as taking precautions to further lower particulates and chemicals in the air, in-house. Our physical plant is kept at an optimum temperature with a low relative humidity (down to 45%).

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.
