Predicting detectability and grading prior to printing
The present disclosure relates generally to image signal processing, including encoding signals for image data or artwork. A color blend/print model is used to predict signal detectability and visibility as is printed on a particular substrate, which facilitates object grading prior to print runs.
1. An image processing method comprising:
obtaining a digital file representing a three-dimensional (“3D”) package, the 3D package including plural panels that adjoin each other, the 3D package comprising an encoded signal printed on at least two (2) of the plural panels;
defining plural pairs of adjoining panels;
determining an encoded signal detectability score for each of the pairs of adjoining panels, the determined encoded signal detectability score being dependent on characteristics of the encoded signal; and
combining the determined encoded signal detectability scores to yield a net score for the 3D package.
2. The method of claim 1 that includes weighting the determined encoded signal detectability score of a first of said pairs with a first weight, and weighting the determined encoded signal detectability score of a second of said pairs with a second weight, before combining said scores to yield the net score.
3. The method of claim 2 in which the first weight is based on a combined area of the first pair of panels, as a fraction of the combined area of all of said panels.
4. The method of claim 3 in which the defining act comprises defining 24 pairs of adjoining panels.
5. The method of claim 1 in which the characteristics comprise an orientation metric and a message metric.
6. A non-transitory computer readable medium comprising instructions stored thereon that, when executed by one or more multi-core processors, cause said one or more multi-core processors to perform the following acts:
obtaining a digital file representing a three-dimensional (“3D”) package, the 3D package including plural panels that adjoin each other, the 3D package comprising an encoded signal printed on at least two (2) of the plural panels;
defining plural pairs of adjoining panels;
determining an encoded signal detectability score for each of the pairs of adjoining panels, the determined encoded signal detectability score being dependent on characteristics of the encoded signal; and
combining the determined encoded signal detectability scores to yield a net score for the 3D package.
7. The non-transitory computer readable medium of claim 6 further comprising instructions that, when executed by said one or more multi-core processors, cause said one or more multi-core processors to perform the following acts: weighting the determined encoded signal detectability score of a first of said pairs with a first weight, and weighting the determined encoded signal detectability score of a second of said pairs with a second weight, before combining said scores to yield the net score.
8. The non-transitory computer readable medium of claim 7 in which the first weight is based on a combined area of the first pair of panels, as a fraction of the combined area of all said panels.
9. The non-transitory computer readable medium of claim 8 in which the defining comprises defining 24 pairs of adjoining panels.
10. The non-transitory computer readable medium of claim 6 in which the characteristics of the encoded signal comprise an orientation metric and a message metric.
11. A system comprising:
memory for storing a digital file representing a three-dimensional (“3D”) package, the 3D package including plural panels that adjoin each other, the 3D package comprising an encoded signal printed on at least two (2) of the plural panels;
means for defining plural pairs of adjoining panels;
means for determining an encoded signal detectability score for each of the pairs of adjoining panels, the determined encoded signal detectability score being dependent on characteristics of the encoded signal; and
means for combining the determined encoded signal detectability scores to yield a net score for the 3D package.
12. The system of claim 11 further comprising means for weighting the determined encoded signal detectability score of a first of said pairs with a first weight, and weighting the determined encoded signal detectability score of a second of said pairs with a second weight, before combining said scores to yield the net score.
13. The system of claim 12 in which the first weight is based on a combined area of the first pair of panels, as a fraction of the combined area of all said panels.
14. The system of claim 13 in which said means for defining is configured for defining 24 pairs of adjoining panels.
15. The system of claim 11 in which the characteristics of the encoded signal comprise an orientation metric and a message metric.
