Your generate process can be successful yet still have warnings regarding contributing pages with errors. If you have contributing pages with errors, Prinergy reports the name of the page in the Process Information dialog box and in the History view.
Problem file affecting others in the process
For input file models 1 and 2, when Prinergy finds a problem in a contributing page during generation, Prinergy also finds errors in all subsequent pages of the same process. These files may not have errors.
To confirm whether or not the files have errors, remove the problem file and regenerate the remaining files. The files will process successfully if they do not have errors.
For models 1 and 2, with the new options Move only common object differences to error layer or Copy only common object differences to error layer, the PDF file linked to the base (common) layer is always considered as the 'control' file. All of the common objects are compared to the common layer objects. If a problem is detected, only the common object from the faulty layer is moved or copied to the error layer. This now enables you to output the common plus non-faulty layers, while you wait for the faulty version/layer to be corrected.
Objects on the error layer
Prinergy LPV extracts the following objects onto a PDF layer, which is, by default, named Error:
- Objects that have been defined with colors that are not specified in the version plan. For example, if no version plan layer is set to extract the color Spot5, then any objects colored with Spot5 are placed on the error layer.
- For input file models 1 and 2, objects from different contributing pages that are meant to be common, but that do not exactly match. For example, if an object in a change layer contributing page has been incorrectly positioned, sized, or colored, but is otherwise the same as the base layer object, the object in the change layer is extracted to the error layer but the object on the base layer is considered the "correct" one and is not moved to the error layer. The object on the change layer is extracted to the error layer in order to prevent potential misregistration on press.
To view errors, in the Pages view, in the Pages pane, open the problem layered PDF page (VP_xxx.pdf) in Acrobat. View the error layer in the problem page, remembering to clear the display of all other PDF layers to isolate the objects in error.
When trying to determine why an object does not match the first set of base objects, remember to compare the following attributes:
- Position
- Font
- Color
- Associated ICC profile
- Clipping path
- The order in which an object is stacked in relation to other objects on the page (z-order)
If you are unable to determine why objects are appearing on the 'error' layer, use Prinergy PDF Compare, a licensed Acrobat plug-in, to help you find the differences between objects.
In Prinergy 7.0 or later, you can mark the faulty objects in the source layer with a red X to better identify the source of the error. For details, see Generate process template.
Note: If you do not want the objects in the error layer to print, you do not need to take any action. Simply leave the objects in the error layer.
