Metrics Description
Maximum ΔH CMY sol-
ids
Highest color difference in ΔH between the measured Lab values of
the CMY solid patches on the color control strip and the Lab values
of the matching patches of the reference printing condition.
Average ΔH composite
grays
Average color difference in ΔH between the measured Lab values of
the composite gray patches on the color control strip and the Lab
values of the matching patches of the reference printing condition.
Maximum ΔH composite
grays
Highest color difference in ΔH between the measured Lab values of
the composite gray patches on the color control strip and the Lab
values of the matching patches of the reference printing condition.
NOTE
Refer to
Patches of the target chart on page 248 to read the description of the patches.
△L (Delta L)
Metrics Description
Average |ΔL| composite
grays
Average lightness difference in |ΔL| between measured Lab values of
the composite gray patches on the color control strip and the Lab
values of the matching patches of the reference printing condition.
Maximum |ΔL| compo-
site grays
Highest lightness difference in |ΔL| between measured Lab values of
the composite gray patches on the color control strip and the Lab
values of the matching patches of the reference printing condition.
Average weighted |ΔL|
composite grays
Average lightness difference in weighted |ΔL| between measured Lab
values of the composite gray patches on the color control strip and
the Lab values of the matching patches of the reference printing con-
dition.
Maximum weighted |ΔL|
composite grays
Highest lightness difference in weighted |ΔL| between measured Lab
values of the composite gray patches on the color control strip and
the Lab values of the matching patches of the reference printing con-
dition.
Average |ΔL| K-only
patches
Average lightness difference in |ΔL| between measured Lab values of
the K-only patches on the color control strip and the Lab values of
the matching patches of the reference printing condition.
Maximum |ΔL| K-only
patches
Highest lightness difference in |ΔL| between measured Lab values of
the K-only patches on the color control strip and the Lab values of
the matching patches of the reference printing condition.
Average weighted |ΔL|
K-only patches
Average lightness difference in weighted |ΔL| between measured Lab
values of the K-only patches on the color control strip and the Lab
values of the matching patches of the reference printing condition.
Maximum weighted |ΔL|
K-only patches
Highest lightness difference in weighted |ΔL| between measured Lab
values of the K-only patches on the color control strip and the Lab
values of the matching patches of the reference printing condition.
Estimated black point |
ΔL|
Lightness difference in |ΔL| between the measured darkest patch on
the color control strip and the darkest patch of the reference printing
condition. The darkest patch is the patch that has the lowest L* val-
ue.
