Influence of Temperature and Humidity on Typographic and Colorimetric Properties of Ink Jet Prints

摘要

The aim of this study was to examine the influence of temperature and relative humidity on the changes in typographic and colorimetric properties of ink jet prints in order to establish what type face style is appropriate for business correspondence, where infor mation permanence needs to be ensured. The prints were made with three ink jet printers from different manufacturers on four differ ent office papers. Four different, widely used typefaces (one old style, one transitional, and two sans-serif) in two different sizes (10 and 12 pt) were tested. The fastness of printed business correspon dence under four different conditions of temperature and relative hu midity were defined using Xenotest Alpha. The color differences were determined spectrophotometrically. The differences in typo graphic tonal density and wicking of typefaces were measured by image analysis. On average, the biggest difference in typographic tonal density was observed after a transitional typeface was exposed to the highest humidity and temperature values.
