Part of my job involves creating pdf documents, inserting pdf maps, locking the documents to prevent alteration but allow printing, and sending them to clients. Recently I updated to Adobe Acrobat 11 Standard. I have since had trouble printing the pdf documents I create; I get an error message "insufficient data for image". Maps in the document don't show up and it can't be printed. If I re-create the document and don't put the permissions password on it, the document is fine. But I need to be able to lock my pdf documents to prevent alteration! Please help!
