Abstract
Abstract A visual calibrator for a digital color imaging proof system includes a series of patches on a carrier layer, the patches composed of combinations of at least two colors in halftone or continuous print, and associated with at least some of the patches are alphanumeric markings which relate to specific changes in an imaging signal for adjustment of the imaging system to modify the color of a proof towards a desired target color.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
73 words
A visual calibrator for a digital color imaging proof system comprising a series of patches on a carrier layer, said patches composed of combinations of at least two colors in halftone or continuous print, and associated with at least some of the patches are alphanumeric markings which relate to specific changes in an imaging signal for adjustment of the imaging system to modify the color of a proof towards a desired target color.
Claim 2
Dependent Claim
73 words
A visual calibrator for a digital color imaging proof system comprising a series of patches on a carrier layer, said patches composed of combinations of at least two colors in halftone or continuous print, and associated with at least some of the patches are alphanumeric markings which relate to specific changes in an imaging signal for adjustment of the imaging system to modify the color of a proof towards a desired target color.
Claim 3
Dependent Claim
14 words
A calibrator sheet comprising more than one visual calibrator as described in claim 1.
Claim 4
Dependent Claim
35 words
The calibrator of claim 1 in which the alphanumerics direct specific signal alterations for a thermal imaging system for at least one color signal selected from the group consisting of cyan, magenta, yellow, and black.
Claim 5
Dependent Claim
18 words
The calibrator of claim 1 wherein said patches extend to an edge or hole on said carrier layer.
Claim 6
Dependent Claim
22 words
The calibrator sheet of claim 2 where at least one target color extends to an edge or hole on said separate carrier.
Claim 7
Dependent Claim
26 words
The calibrator of claim 1 wherein said alphanumerics contain specific instructions for the adjustment of the imaging system to alter an energy output of that system.
Claim 8
Dependent Claim
26 words
The calibrator of claim 2 wherein said alphanumerics contain specific instructions for the adjustment of the imaging system to alter the energy output of that system.
Claim 9
Dependent Claim
27 words
The calibrator sheet of claim 5 wherein said alphanumerics contain specific instructions for the adjustment of the imaging system to alter the energy output of that system.
Claim 10
Dependent Claim
31 words
The calibrator sheet of claim 2 wherein there are also single color halftone images representing specific percentages of halftone dots, with holes available in the halftone images for viewing a proof.
Claim 11
Dependent Claim
31 words
The calibrator sheet of claim 5 wherein there are also single color halftone images representing specific percentages of halftone dots, with holes available in the halftone images for viewing a proof.
Claim 12
Dependent Claim
28 words
The visual calibrator of claim 1 having holes in said carrier which extend to said patches and a second layer beneath said holes which can support a proof.
Claim 13
Dependent Claim
28 words
The calibrator sheet of claim 2 having holes in said carrier which extend to said patches and a second layer beneath said holes which can support a proof.
Claim 14
Dependent Claim
28 words
The calibrator sheet of claim 5 having holes in said carrier which extend to said patches and a second layer beneath said holes which can support a proof.
Claim 15
Dependent Claim
28 words
The calibrator sheet of claim 8 having holes in said carrier which extend to said patches and a second layer beneath said holes which can support a proof.
Claim 16
Dependent Claim
28 words
The calibrator sheet of claim 10 having holes in said carrier which extend to said patches and a second layer beneath said holes which can support a proof.
Claim 17
Dependent Claim
16 words
The visual calibrator of claim 1 in which the alphanumerics are defined in a look-up table.
Claim 18
Dependent Claim
16 words
The visual calibrator of claim 11 in which the alphanumerics are defined in a look-up table.
Claim 19
Dependent Claim
17 words
The calibrator sheet of claim 2 in which said imaging system is a thermal transfer imaging system.
Claim 20
Dependent Claim
17 words
The calibrator sheet of claim 5 in which said imaging system is an electronically driven imaging system.
Claim 21
Dependent Claim
74 words
A visual calibrator for digital color imaging proof systems comprising a series of patches on a carrier layer, said patches composed of combinations of at least three colors in halftone or continuous print, and associated with at least some of the patches are alphanumeric markings which relate to specific changes in an imaging signal for adjustment of an electronically driven imaging system to modify the color of a proof towards a desired target color.
Claim 22
Dependent Claim
