We recently received a complaint from a large customer, complaining that they are not able to open the PDF. They are accessing the PDF via Internet Explorer and Adobe Acrobat Reader plugin.  The error they are presented with is There was an error processing a page, Invalid ColorSpace. 

We tried the same, and the file seems to open fine when saved to disk, tried Save Original, Save with Annotations, Save without Annotations, but fails to open via Browser. It seems to affect some of the documents (not all).

Various forums advise to save the PDF to disk and then open.

The origin of the file is Docuware Scan App, (Desktop Apps), using a Canon 1060 Scanner. 

As per Adobe Forum, they are blaming a non compliant PDF/A or syntax errors within the PDF.

We are using DW6.7 HF54 


My question is as follows:

1. if Docuware sends a document via email, does it manipulate the file or convert it to PDF/A prior to sending?

2. Is there a fix that can be applied to fix this issue.

Other suggestions or potential fixes?

I assume that when you say it fails to open in a browser, you mean the DocuWare Viewer. A PDF is rendered to a PNG file for viewing in DocuWare. This then indicates that the DocuWare rendering engine is throwing the error. I suggest that you open a support request so that we can investigate what is happening. If this has only recently shown up as a problem, we may be able to find what happened to cause this.
Please be sure to include a couple of example documents when you create the support request.

Just some feedback, it seems the when scanning documents with Canon imaging software, its not fully PDF/A compliant as confirmed by Adobe Acrobat Pro reports (missing output intent), however when it is scanned from Docuware Desktop Apps, it is PDF/A compliant.  The issue that arises, is that when the document is emailed to a customer as an attachment, through a workflow and viewed in a webbrowser with an adobe reader extension, it complains about color space and refuses to open the file, if the customer downloads the file, and views it in the desktop application, the document can be viewed. Enfocus Pitstop Server may be used to preflight files as an intermediate step, (would be nice if the Docuware workflow can output the file to a folder, then collect the processed file from folder and continue the workflow. (not sure if the later version has this already?

Which version of the document produces the error? Adobe's or DocuWare's? It is also not clear what PDF/A has to do with color space.
DocuWare workflow will never move a document from the file cabinet, wait for some activity and then re-store it. Be clear that Workflows do not store documents, move documents, copy documents, delete documents. They only act on index entries. This will not change.
