Precision White Point and Black Point Targets
Precision White Point/Black Point Targets are used to visually determine
the white and black point settings and systemize digital printing for specific
printer/media combinations. Proper white and black point systemization can
greatly improve your digital output. By visually judging a print's shadows
and highlight tonal separation in a color managed printing work flow, you
can achieve more consistent results and produce full-scale, full-substance
prints.
The Tone System
The Tone System is a process for color correcting digital images. It incorporates
color management and specifically addresses systemizing white point and
black point settings for specific printer/media combinations. The use of
Precision White and Black Point Parameter Targets allows the photographer
to predict the tonal separation in highlights and shadows to a higher degree
than with color management alone.
By following the six-step Tone System Color Correction Routine and applying
visual evaluation results from the Precision White and Black Point Parameter
Targets, photographers and digital printers can achieve more accurate color,
richer tonal ranges, and better shadow and highlight detail in their digitally
produced images.
In addition to accurate color representation, images processed with the
Tone System Color Correction Routine and systemized with Precision White
and Black Point Parameter Targets can achieve full scale, full substance
tonal rendition.
Tone System Color Correction
The Tone System Color Correction Routine is a six-step process for correcting the color bias of digitized images. All capture devices lend their own color bias to the image being digitized based on lighting, capture device settings, and inherent aspects of capture technology.
Tone System Color Correction Routine consists of six steps:
- White Point Setting (Highlight Tone)
- Black Point Setting (Shadow Tone)
- Midpoint Tone Setting (Density Correction)
- 1/4 and 3/4 Tone Settings (Contrast Correction)
- Channel Tones Settings (Color Cast Correction)
- Saturation Setting (Color Purity)
