Question details
The user wants to prevent Adobe Acrobat from automatically straightening or altering the orientation of scanned pages during the OCR process.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Running OCR on scanned PDF documents using the Acrobat Enhance Scans feature.
- Observed behavior
- Acrobat automatically deskews the scanned pages even though the Deskew filter has been explicitly turned off in the application settings.
Ensure your Adobe Acrobat is updated to the latest version, as bugs involving application settings not saving or applying correctly are often patched in software updates.
Verify and Re-configure Enhance Scans Filters
Double-check your Adobe Acrobat settings to ensure the Deskew filter is properly disabled within the Scanned Documents options.
Acrobat sometimes defaults to applying its standard enhancement filters when running OCR. You must ensure the specific Deskew filter is disabled in the deepest level of the Enhance Scans settings menu.
Launch Adobe Acrobat, navigate to the 'Tools' menu at the top, and select 'Enhance Scans'.
In the toolbar that appears, click on 'Enhance' and then choose 'Scanned Documents' from the dropdown menu.
Click on 'Settings' (the gear icon), locate the 'Filters' section in the dialog box, and click 'Edit'.
Find the 'Deskew' option, toggle it to 'Off', and click 'OK' to save your preferences before running OCR again.
Perform Accurate OCR Without Layout Distortion in WPS Office
If Acrobat's automatic adjustments are altering your scanned documents against your preferences, try WPS PDF. The WPS OCR tool extracts text highly accurately while giving you full control over how your original scanned images and layouts are handled.
- 1. Open PDF in WPS: Launch WPS Office and open your scanned PDF document using the WPS PDF editor.
- 2. Access the OCR Tool: Navigate to the 'Tools' tab on the top ribbon and click on the 'OCR' button.
- 3. Select OCR Mode: Choose whether you want to extract the text directly or convert the document into a fully searchable PDF.
- 4. Process Document: Click 'Start OCR' to process the document seamlessly without unwanted automatic image rotation or deskewing.
Frequently Asked Questions
What does deskewing a scanned document mean?
Deskewing is an image processing feature that detects if a scanned page was placed crookedly on the scanner and automatically straightens it so the text aligns horizontally.
Why do PDF editors automatically deskew pages during OCR?
Optical Character Recognition (OCR) algorithms require text to be perfectly horizontal to accurately recognize individual characters. Therefore, software often applies deskewing automatically to maximize text recognition accuracy.
How can I find my exact Adobe Acrobat version?
Open Acrobat, go to the 'Help' menu at the top, and click 'About Adobe Acrobat'. A dialog box will display your current version number, which is useful when reporting unresolved software bugs.
