Patch Formulation Technology
The patches in SpyderCHECKR are composed of pigment-based colors with
carefully formulated spectral characteristics, ideal for camera calibration in
varying lighting conditions. The SpyderCHECKR also provides spectrally
neutral black, white, and gray patches.
The patches are durable and produced to close tolerances. A CHECKR which
sees only moderate usage will last almost indefinitely. Replacement cards are
available for purchase from the Datacolor webstore for circumstances
involving heavy use, or in cases where the patches become scratched, worn,
or soiled over time. Please avoid touching the patches in your
SpyderCHECKR, as oils from the skin can affect the patch color and texture.
Color Patches
The color patches on the right half of the SpyderCHECKR, and those on the
SpyderCHECKR24 represent the standard 24 colors used in a variety of color
products. These patches are near or within the sRGB color gamut to avoid
gamut clipping, and assure usability with a wide range of capture, display and
output devices. Note: the order that various software programs read these
standard 24 colors varies, but the SpyderCHECKR provides them in a
serpentine pattern, such that reading down one column and up the next will
produce the usual measurement order.
The color patches in the left half of the 48 patch SpyderCHECKR represent
additional colors targeting several uses. There are six additional skintones, for
a total of eight. There are six medium saturation color patches, in the red,
green, blue, cyan, magenta, and yellow zones, to improve the coverage of the
inside of the color gamut.
There are three near white tints and three near black tones, for checking color
tints and tones at both ends of the dynamic range. And the gray ramp has
been increased from the standard 20% steps, to 10% steps, plus extra
samples at 5% and 95% to provide a more detailed gray ramp.
