In the professional environment from time to time we have to comment or place stamps on Adobe PDF documents. In doing so, we add stamps or comments to the pdf which usually are in a red box with an arrow callout. When dealing with stamps and comments there are numerous problems that can come about. For one, if you would like to print the pdf, you have to make sure that you print the pdf with comments. Also, when sending the PDF document to other people, they are able to edit and or delete your PDF comment or stamps. What we want to do is make the comments uneditable. This means we have to flatten the PDF file. Don’t go around searching for software to do it. Just follow these instructions and you will be able to merge all your comments into the document when you comment on PDF..
