In-Depth Information
The Eye-One Pro Spectrophotometer also has an optional attachment
called the
Beamer
, which allows the unit to calibrate and profile a digital
projector. For those doing presentations from a computer hooked up to
such a digital projector, the Beamer and Eye-One Pro Spectrophotome-
ter is a necessity when projecting images. The ICC profile built for the
digital projector doesn't affect the projector but instead loads a correction
LUT to the graphic system on the computer driving the projector. I never
travel and conduct a seminar anymore without first calibrating the digital
projector because it makes a huge difference in quality. In addition, there
is an optional robotic arm for the Eye-One Pro Spectrophotometer called
the
Eye-One iO
, which allows a user to automate the scanning of targets
(see Fig. 6-5). This device also comes with an optional transparent base
to measure various transparent materials and can handle targets as thick
as 10 mm.
GretagMacbeth has a Spectrophotometer called the
Spectrolino
, which
can be used in a spot mode to build a printer profile. However, the way
in which this unit really becomes productive is when inserted onto its
optional X/Y table called the
Spectroscan
, as seen in Fig. 6-4. This
Spectrophotometer, therefore, can be used in either spot or automated
mode and can be used with an attachment to calibrate and profile a
display. The Spectrolino has been around for many years and is an excel-
lent device; I would strongly recommend it be used to build printer pro-
files with the X/Y table. This unit does not have the ability to scan a row
like the Eye-One Pro, PULSE, or Spectrocam, therefore using it as a one-
patch-at-a-time unit is not effective. With the X/Y table, a user can sample
from one to five measurements per patch. The robotic arm can move in
very small and precise increments and measure hundreds of patches
unattended. The downside is the speed of the unit. It takes about 45
minutes to read 900 patches taking only a single reading per patch.
