How the glossary relates to the rest of the site
Several terms here cover ground that has its own page. Paper terms (basis weight, GSM, caliper) are expanded on paper weight conversions and coated and uncoated paper. Mail terms (EDDM, flat, metering, nonmachinable) are expanded on USPS mailing prices, 2026 and direct mail. Plan sizes (Arch D, Arch E) are set out in full on reprographics.[3][16][2]
A few terms are used differently in different places. Replica’s “B size” is 12 × 18 inches (Arch B), while ANSI B is 11 × 17 inches. Its resolution guide calls CMYK additive, but CMYK is a subtractive model. This glossary follows the standard meaning and notes the company’s usage where it differs.[1][2][4][7]
Not in this glossary
Terms the official pages use only as marketing language, such as “HD imaging,” are not defined here, because the pages do not explain what they mean in technical terms.[24] Names of specific press models are left out because the company does not publish them.
