A unique hand-held instrument intended for the imagesetting environment. The Betalog 130 is the only one-piece instrument capable of reading both films and reflection copy. Read any size films on a light table, not limited by instrument throat depth.
Read dot area in positive or negative form and density in transmission mode to 6.00D. Stochastic and conventional halftones can be read with equal ease and accuracy. Reflection mode uses Murray-Davies equation compensation for greatest accuracy with different proof and repro materials. Yule-Nielson "n" factor is available in reflection mode to improve the agreement between measurements and visual comparison.
The Betalog Model 130 is equipped with a serial data port for connection to an optional printer or directly to a computer for data collection and analysis. Optional PostScript calibration software allows linearization to be accomplished directly from the densitometer. Optional cables are available for connection to PC or Macintosh computers.
Portable and battery powered for convenience, micro-processor based for ease-of-use and accuracy. Part of a family of quality control instruments for the new graphic arts industry.
