The Practical Use of a Handheld Spectrophotometer for Print Properties Analysis

A previous TAGA paper suggested the use of the right instrument for the right job in the measurement of graphic arts ink and print properties. The paper explores the use of a new instrument that combines some of the instruments previously studied into one device, a handheld portable spectrophotometer and densitometer. The paper details the comparison of the handheld spectrophotometer to a referee device, the Diano Spectrophotometer, for a variety of printed halftone samples and compares the practical uses of spectrophotometry, colorimetry, and densitometry in the graphic arts.
