BETALOG 130
The Betalog 130 is a combination reflection/transmission densitometer. A
unique handheld 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 Mac or PC computers.
