Abstract

In an example of the disclosure, first and second print jobs are received at a printer. The first and second print jobs each include production frames. The first and second print jobs are printed with a media roll change occurring during printing. A first finishing device information nonproduction (“FDIN”) frame and a second FDIN frame are printed. The first and second FDIN frames include coded information regarding the first print job and the second print job, respectively. The coded information is for reading by a scanner at a finishing device. A press calibration nonproduction (“PCN”) frame that includes a printer calibration diagnostic is printed. A scanner at the printer is caused to capture the printer calibration diagnostic. A calibration operation is performed at the printer utilizing data or attributes captured from the printer calibration diagnostic.

First claim

What is claimed is:

1. A printing method utilizing media roll changes and nonproduction frames, comprising:
receiving at a printer first and second print jobs, wherein the first and second print jobs each include production frames;
printing the first and second print jobs with a media roll change occurring during printing;
printing a first finishing device information nonproduction (“FDIN”) frame and a second FDIN frame, the first and second FDIN frames including coded information regarding the first print job and the second print job, respectively, wherein the coded information is for reading by a scanner at a finishing device;
printing a press calibration nonproduction (“PCN”) frame that includes a printer calibration diagnostic;
causing a scanner at the printer to capture the printer calibration diagnostic; and
performing a calibration operation at the printer utilizing data or attributes captured from the printer calibration diagnostic.

2. The method of claim 1 , further comprising determining the media roll change is to occur during printing based upon one from the set of a received print job manifest, an observed limitation of available media at a supply roll, and an observed limitation of capacity at a take-up roll.

3. The method of claim 1 , wherein the media roll change includes one from the set of a splicing media so as to switch media feed from a first supply roll to a second supply roll, and a splicing of media to switch media collection from a first take-up roll to a second take-up roll.

4. The method of claim 1 ,
wherein the media roll change is from a first take-up roll to a second take-up roll, the media roll change including splicing of a media at a splice line;
wherein the first print job is printed upon the media ahead of the splice line; and
wherein the FDIN frame is printed upon the media after the printing of the first print job and ahead of the splice line.

5. The method of claim 1 , wherein the media roll change is to occur without interrupting printing of the first and second print jobs, and such that no portion of a production frame, a FDIN frame, or a PCN frame is printed on a splice line.

6. The method of claim 1 , wherein the finishing device is in-line with the printer, wherein the first FDIN frame is printed before printing of the first print job, and wherein the second FDIN frame is printed before printing of the first second job.

7. The method of claim 1 , wherein the reading by a scanner at a finishing device is to inform the finishing device of an attribute of a subject production frame of the first and/or second print jobs, and settings of the finishing device for performing a post-printing action upon the subject production frame are to be modified based upon the reading of the coded information.

8. The method of claim 7 , wherein the finishing device is a cutting finishing device and the post-printing action is a cutting action.

9. The method of claim 1 , wherein the calibration operation is to modify a setting of the printer for the second print job.

10. The method of claim 1 , wherein the calibration operation is one from the set of an image registration calibration and a color accuracy calibration.

11. The method of claim 1 , wherein the calibration operation is a verification calibration operation.

12. A system for printing with media roll changes and nonproduction frames, comprising:
a job receipt engine, to receive a set of print jobs at a printer, wherein each print job includes a production frame;
a job print engine, to cause printing of the set of print jobs;
a media roll change engine, to cause a media roll change to occur during printing of the set of print jobs;
a FDIN frame engine, to cause printing of a finishing device information nonproduction (“FDIN”) frame for each of the first and second print jobs, with each FDIN frame including coded information for reading by a scanner at a finishing device to modify a setting of the finishing device;
a PCN frame engine, to cause printing of a press calibration nonproduction (“PCN”) frame that includes a printer calibration image;
a scanning engine, to cause a scanner to capture the printer calibration diagnostic and create scan data representative of the printer calibration diagnostic; and
a calibration engine, to perform a calibration operation at the printer based upon the scan data.

13. The system of claim 12 , wherein the media roll change engine is to determine the media roll change is to occur and cause the media roll change based upon one from the set of a received print job manifest, an observed limitation of available media at a supply roll, and an observed limitation of capacity at a take-up roll.

14. A printer, comprising:
a marking agent application component to form images upon a web media in accordance with a received print job;
a media transport component to cause movement of the web media past the marking agent application component;
a scanner;
a controller to
receive first and second print jobs;
determine a media roll change is to occur during printing;
cause printing of the and second print jobs with the media roll change;
cause printing of a finishing device information nonproduction (“FDIN”) frame for each of the first and second print jobs, with each FDIN frame including coded information to be read at a cutting finishing device, the coded information for modifying a setting of the cutting finishing device;
cause printing of a press calibration nonproduction (“PCN”) frame that includes a printer calibration diagnostic;
cause the scanner to capture the printer calibration diagnostic and create scan data representative of the printer calibration diagnostic; and
calibrate the printer utilizing the scan data, wherein the calibration to modify or verify a printer setting for the second print job.

15. The printer of claim 14 , wherein the media roll change is to occur without interrupting printing of the first and second print jobs, and wherein no portion of the first or second print job, the FDIN frame, or the PCN frame is to be printed on a splice line.
