Every element of CAW's
digital workflow is calibrated and profiled.
We profile input devices
(scanners and cameras) using reflective and
transmission targets, such as the X-Rite Digital
ColorChecker SG Card, Golden Thread target, or
the HutchColor HTC target. Equipment used for
projects involving specific photographic media
is profiled against the appropriate IT8 or Q-60
Monitors are regularly
checked and calibrated.
Custom profiles are prepared
for all printer/paper combinations.
LVT film recorders are
calibrated using X-Rite Model 811 and Model
310T/R transmission/reflection densitometers.
