Lookup the DPI of a PDF in Acrobat

You can check the resolution of a PDF image by using the Preflight tool. In this example, I'm working with Acrobat XI.

1. Go to Tools . . . Print Production . . . Preflight.

2. On the Profile tab, click open the PDF/X Compliance drop down menu and then choose Verify Compliance with PDF/X-1a. Then click 'Analyze'.

3. You will be moved to the 'Results' tab. Look in the Overview drop down menu. There will be a submenu for Images which will show the width and height for each page in pixels.

4. Pages of a different print sizes (8.5 x 11; 11 x 17, etc.) will have set pixel dimensions for standard resolutions such as 300 PPI. So a PDF letter size page with pixel dimensions of 2550 x 3300 will have a resolution of 300 PPI.

5. Alternatively, if you click on the magnifying glass icon on the toolbar of the Profiles tab, and then in the Image drop down menu select the option for 'Resolution of bitmap images between 300 and 600 dpi', you can Analyze the resolution of each page.

PDFs do not have a single resolution. There is a different resolution for each object in the file. The resolution of text and vector images will not change with magnification.

Working with Java scripts

Don't miss how easy it can be to write and execute your own Java script in Adobe Acrobat. If you'd like to extract specific page ranges from a PDF, you can use a script like this:

this.extractPages(21,30);

this.extractPages(51,60);

this.extractPages(101,110);

1. On the Tools panel, go to Action Wizard and select 'Create New Action . . . '

2. In the More Tools menu, click on 'Execute JavaScript'.

3. Clicking on 'Specify Settings' will open the JavaScript Editor.

4. Save and name the new action.

5. You will then be able to execute the new action from the Action Wizard menu. This script will quickly extract just the designated ranges.

Export Highlighted Text from Multiple Transcripts to Spreadsheet

When preparing deposition designations, or simply when identifying relevant testimony during witness preparation, it's common for attorneys to highlight page and line ranges in multiple deposition transcripts. If you'd like to export the highlighted testimony from multiple transcript PDFs to an Excel file or Word document, follow these steps.

1. Before any highlighting takes place, be sure that the text selected to be highlighted will be added into comments. Using Adobe Acrobat, in the Edit menu, select Preferences and then click on the Comments category. Check the option to, "Copy selected text into Highlight, Strikethrough, and Underline comment pop-ups".

2. When page and line ranges are highlighted the text will be automatically added into new comments.

3. In the right sidebar, select 'Comment'. A comments list will be displayed at the bottom.

4. Select the Options icon, and then choose 'Create Comment Summary' in the drop down menu.

5. Select 'Comments only' in the dialog box, then click the 'Create Comment Summary' button.

6. A new PDF will be created with only the highlighted text. This text can then be saved to an Excel file.

7. If you are working with multiple transcripts, create an Adobe action to process the PDFs. First, go to Tools . . . Action Wizard, and click 'Create New Action'

8. In the Content menu on the left, select 'Create Comment Summary', and move it to the right. Uncheck the 'Prompt User' box.

9. Click on 'Specify Settings' and choose the comments only layout. Save and name the action.

10. Click on the action from the Tools . . . Action Wizard menu. Select the option to add the files you need and then click start.

11. A new PDF will be created with just the selected text for each source file, and be save to the same folder as the source files. You can easily combine these and then export the text to an Excel file.

Note that in order get this process to work correctly, it may be necessary to edit the tags of the PDFs. See the Tip of the Night for February 4, 2019.
