collected data is sent to the host software. This method is not only fast,
but it produces multiple measurements per patch. For example, both the
Eye-One Pro and PULSE are able to collect more than 100 measurements
per second. Even if the user moves the Spectrophotometer across the row
of patches quickly, multiple samples per patch are measured. The X-Rite
PULSE can measure up to 3000 patches without having to be tethered
to the host computer, powered using its rechargeable battery. The data is
stored inside the unit after which it is downloaded to the host software
via a USB cable.
The Eye-One Pro, PULSE, and the Spectrocam can be used in spot mode
whereby the user can read just a single patch of any object they wish. These
devices in spot mode can be used for other tasks besides building printer
profiles, as the spectral data from these devices is useful for a myriad of
uses. For example, these products would be ideal for measuring a Macbeth
ColorChecker to create a custom Target Description File. A user may want
to sample the color of a printed logo to ascertain the spectral data to use
in Photoshop's color picker. Collecting this kind of data can even be used
when building a camera profile using some software products.
In Chapter 4, I discussed that ProfileMaker Pro's digital camera
module has an option to measure colors using the Eye-One Pro for use
in building a camera profile. The Eye-One Pro Spectrophotometer also
has the ability to read ambient light and electronic flash. When an
ambient head is placed on the unit, the user can measure ambient light
by using the supplied Eye-One Share software. Click the measure button
on the unit and hold the Eye-One Pro Spectrophotometer under a light
box or in front of a studio flash to read the spectral makeup of the light.
