A Little About Archival Quality

External Factors – Production

  • Offset Printing (generally 100 or more books)

Offset printing involves chemicals which may overcome the buffering of the standard paper to some extent.  The process takes place at room temperature with standard lighting and both sides of the page are printed at once.  We use a non-oxidizing, rubber base ink (pH-N/A) rather than an oil base.

  • Digital Printing (generally 99 or fewer books)

The paper is subjected to high heat and light during the initial transfer process.  Note it goes through this process twice for book pages, once for each side.  The black powder toner seems to have quite a resistance to secondary heat sources.
