Print monitoring system and method
View Patent ↗A print monitoring system comprising a printer that generates a printed object that comprises a) a printed area located on a substrate, the printed area having a predetermined width and defining a two-dimensional matrix having a plurality of rows and a plurality of columns; b) print indicia printed on the substrate within the two-dimensional matrix of said printed area such that at least one row of the plurality of rows contains print indicia that are separated by a maximum width; and c) at least one print validation symbol printed on the substrate in a predetermined first validation print area. The system can also comprise an image capture device configured to read at least the at least one validation symbol and a controller in communication with the image capture device that compares the at least one validation symbol to a predetermined at least one validation symbol and makes quality control decisions based on the comparison.
1. A print monitoring system, comprising:
a. a printer that generates a printed object, the printed object comprising:
i. substrate adapted to be printed thereon;
ii. a printed area located on said substrate, the printed area having a predetermined width, the printed area further defining a two-dimensional matrix having a plurality of rows and a plurality of columns;
iii. print indicia printed on said substrate within the two-dimensional matrix of said printed area such that at least one row of the plurality of rows contains print indicia that can be spaced along a transverse axis of said substrate to a maximum width; and
iv. at least one print validation symbol printed on said substrate in a predetermined first validation print area, wherein the at least one print validation symbol extends at least about the maximum width of the print indicia, and wherein the at least one print validation symbol is printed on the first validation print area such that the at least one print validation symbol is substantially co-axial with a portion of each column of the plurality of columns;
b. an image capture device configured to read at least the at least one validation symbol; and
c. a controller in communication with the image capture device that compares the at least one validation symbol to a predetermined at least one validation symbol and makes quality control decisions based on the comparison.
2. The print monitoring system of claim 1 , wherein the printed object further comprises a second validation print area on said substrate that has a predetermined area that is substantially blank, wherein the image capture device is configured to read the second validation print area, and wherein the controller determines if there are print markings in the second validation print area.
3. The print monitoring system of claim 2 , wherein the first and second validation print areas are co-located.
4. The print monitoring system of claim 2 , wherein at least a portion of the second validation print area is within the printed area of the substrate.
5. The print monitoring system of claim 2 , wherein the second validation print area has a width at least about the maximum width of the print indicia.
6. The print monitoring system of claim 2 , wherein the printed object is a lottery ticket.
7. The print monitoring system of claim 1 , wherein at least a portion of the first validation print area is within the printed area of the substrate.
8. The print monitoring system of claim 1 , wherein the at least one print validation symbol has a predetermined height sufficient to reach a threshold of visibility for the image capture device.
9. A method of monitoring the output of a printer, comprising:
printing, on an imprintable substrate, quality control information in a manner detectable by a print monitoring system, the imprintable substrate having a printed area having a predetermined width and defining a two-dimensional matrix having a plurality of rows and a plurality of columns, print indicia being printed on the substrate within the two-dimensional matrix such that at least one row of the plurality of rows contains print indicia that can be spaced along a transverse axis of said substitute to a maximum width;
defining a first validation print area on said substrate;
printing at least one validation symbol in the first validation print area so that said validation symbol extends at least about the maximum width of the print indicia; capturing an image of the at least one validation symbol with the print monitoring system; and analyzing the image to indicate the quality of the print indicia printed on the substrate with the print monitoring system.
10. The method of claim 9 , further comprising defining a second validation print area on the substrate that has a predetermined area that is substantially blank.
11. The method of claim 10 , wherein the second validation print area has a width at least about the maximum width of the print indicia.
12. The method of claim 10 , wherein the first and second validation print areas are substantially co-located.
13. The method of claim 10 , further comprising capturing an image of the second validation print area and determining if there are markings in the second validation print area.
14. The method of claim 13 , further comprising identifying imprintable substrates in which a printing error is detected in the first validation print area.
15. The method of claim 14 , further comprising identifying imprintable substrates in which a printing error is detected in the second validation print area.
16. The method of claim 15 , further comprising storing data that identifies imprintable substrates having a printing error.
17. The method of claim 15 , further comprising displaying data to an operator that identifies imprintable substrates having a printed error.
