Methods of manufacture and use of customized flexomaster patterns for flexographic printing
View Patent ↗A method of flexographically printing a uniform pattern on a substrate where the ink deposited on the substrate is deposited in the intended location and not in unintended locations. A flexo-master comprises a pattern formed by a plurality of lines including at least one junction, and printing the pattern including the at least one junction in ink on a substrate forming a printed pattern, wherein the printed junction has a different shape than the at least one junction on the flexo-master. In addition to the junction formation, a discontinuous line on the flexo-master may be used to print a continuous line, a single line may be used to print two lines, and two or more lines may be used to print a single line. The flexo-master pattern lines may additionally have a fill pattern comprising various geometries that are used to uniformly print the pattern on the substrate.
1. A system for flexographically printing a microscopic pattern using a plurality of flexo-masters comprising:
a plurality of printing plate cylinders and a plurality of flexo-masters,
a substrate;
wherein at least some of the plurality of printing plate cylinders are used to print a single pattern using at least one ink type from at least one ink source;
wherein each flexo-master of the plurality of flexo-masters is disposed on each of the at least some of the plurality of printing plate cylinders and comprises at least a portion of the single pattern, wherein each portion of the single pattern comprises a plurality of lines;
wherein at least one flexo-master of the plurality of flexo-masters comprises a pattern formed by a plurality of lines including at least one junction; and
wherein at least one of the lines of the plurality of lines is a discontinuous line; and wherein the at least one flexo-master prints the pattern on the substrate using the ink, wherein the printed junction has a different shape than the at least one junction on the flexo-master, and wherein the at least one discontinuous line prints a continuous line on the substrate.
2. The system of claim 1 , wherein each flexo-master deposits the at least one ink type in a plurality of predetermined locations associated with the single pattern.
3. The system of claim 1 , wherein each flexo-master does not deposit the at least one ink type in areas other than a plurality of predetermined locations associated with the single pattern.
4. The system of claim 1 , wherein a single line of the plurality of lines simultaneously prints two separate, parallel lines on the substrate.
5. The system of claim 1 , wherein a first line of the plurality of lines is parallel to a second line of the plurality of lines, wherein the first and second line are used to form a single line on the substrate.
6. The system of claim 2 , wherein the junction on the flexo- master includes one or more hollow voids, and wherein the printed junction does not include hollow voids.
