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, comprising:
printing a first print job on web media;
printing a first finishing device information nonproduction (FDIN) frame on the web media after the first print job is printed;
printing a second print job on the web media after the first FDIN frame; and
printing a second FDIN frame on the web media after the second print job, wherein the first and second print jobs are performed with a media roll change, wherein the media roll change is comprised of splicing media from a first supply roll to a second supply roll or splicing media from a first take-up roll to a second take-up roll, and wherein the first FDIN frame includes coded information indicating instructions for finishing the first print job by a finishing device and the second FDIN frame includes coded information indicating instructions for finishing the second print job by the finishing device.

2. The printing method of claim 1 , wherein the first FDIN frame precedes a production frame of the first print job and the second FDIN frame precedes a production frame of the second print job when the web media is unwound at the finishing device.

3. The printing method of claim 1 , wherein:
the web media includes at least one splice line, and
the first print job and the first FDIN frame are printed in advance of the at least one splice line and the second print job and the second FDIN frame are printed after the at least one splice line.

4. The printing method of claim 1 , further comprising: printing a press calibration nonproduction (PCN) frame on the web media at a location between the first FDIN frame and a production frame of the first print job.

5. The printing method of claim 4 , wherein the PCN frame is printed between two splice lines on the web media.

6. The printing method of claim 4 , wherein: the PCN frame includes a printer calibration diagnostic which includes information that indicates how a calibration operation is to be performed.

7. The printing method of claim 1 , wherein the coded information indicates a setting of the finishing device.

8. The printing method of claim 1 , wherein the first FDIN frame includes a diagnostic or calibration pattern.

9. The printing method of claim 1 , wherein the first FDIN frame includes one or more alignment fiducials.

10. The printing method of claim 1 , wherein the first FDIN frame includes one or more color calibration fiducials.

11. A printing method, comprising:
printing a first finishing device information nonproduction (FDIN) frame on web media;
printing a first print job on web media after the first FDIN frame;
printing a second FDIN frame on the web media after first FDIN frame; and
printing a second print job on the web media after the second FDIN frame; and
wherein the first and second print jobs are performed with a media roll change,
wherein the media roll change is comprised of splicing media from a first supply roll to a second supply roll or splicing media from a first take-up roll to a second take-up roll, and
wherein the first FDIN frame includes coded information indicating instructions for finishing the first print job by a finishing device and the second FDIN frame includes coded information indicating instructions for finishing the second print job by the finishing device.

12. The printing method of claim 11 , wherein the finishing device receives the first FDIN frame before the first print job.

13. An apparatus comprising:
a memory to store instructions; and
a controller to execute the instructions to control:
printing a first print job on web media;
printing a first finishing device information nonproduction (FDIN) frame on the web media after the first print job is printed;
printing a second print job on the web media after the first FDIN frame; and
printing a second FDIN frame on the web media after the second print job,
wherein the first and second print jobs are performed with a media roll change,
wherein the media roll change is comprised of splicing media from a first supply roll to a second supply roll or splicing media from a first take-up roll to a second take-up roll, and
wherein the first FDIN frame includes coded information indicating instructions for finishing the first print job by a finishing device and the second FDIN frame includes coded information indicating instructions for finishing the second print job by the finishing device.

14. The apparatus of claim 13 , wherein:
the web media includes at least one splice line, and
the controller is to control printing of the first print job and the first FDIN frame in advance of the at least one splice line and printing of the second print job and the second FDIN frame after the at least one splice line.

15. The apparatus of claim 13 , wherein:
the controller is to control printing of a press calibration nonproduction (PCN) frame on the web media at a location between the first FDIN frame and a production frame of the first print job,
wherein the PCN frame includes a printer calibration diagnostic which includes
information that indicates how a calibration operation is to be performed.
