DESKEW ACROBAT PDF

Posted on June 3, by Rick Borstein Comments 0 One of the nice things about working for Adobe is that occasionally nice things show up on my doorstep. That was the case a few months ago when a Fujitsu fi scanner arrived. My test of this scanner was delayed as I waited for my new laptop to arrive. Fujitsu fi scanner on my messy desk.

You can configure the scanning presets or use the Custom Scan option to scan with the settings of your choice. The scanning presets are not available on Mac OS. Then, in the Acrobat scan interface, select a scanner and a document preset or Custom Scan. Choose Scanner to see the options available. On Windows: Create PDFs from Scanner interface; clicking the settings or gear icon shows all the settings for the selected option.

If you want to scan multiple files into a PDF, click the Settings icon. The Custom Scan interface is displayed. Select the Prompt to scan more pages check box. Click Scan. If you want to change the settings, click the Settings icon. Select scanning options as needed. Consult the scanner documentation information on available options. In Mac OS, the scanner user interface is always shown. Click the Settings icon next to the preset. Adjust the settings as needed.

If you want to scan multiple files into a PDF, select the Prompt to scan more pages check box. Click Save Settings to save the preset, and then click the Cross button X to close. Click here to see all the scanning options Scanner Select an installed scanner. You must have the manufacturer scanning software installed on your computer.

In Windows only, click the Options button to specify scanner options. When the option is not selected, scanning starts directly with the settings specified in the Custom Scan or Configure Predefined Settings interface. Pages Specify single or double-sided scanning. If you select Both Sides and the settings of the scanner are for only one side, the scanner setting overrides the Acrobat settings.

Note: You can scan both sides of pages even on scanners that do not themselves support two-sided scanning. When Both Sides is selected, a dialog box appears after the first sides are scanned. You can then reverse the original paper documents in the tray, and select the Scan Reverse Side Put Reverse Of Sheets option in that dialog box.

This method produces a PDF with all pages in the proper sequence. This option is enabled if your Scanner Options are set to use the Acrobat scanning dialog box instead of the scanner application. Resolution Windows only Select a resolution that your scanner supports. Note: If you select a Color Mode or Resolution option not supported by your scanner, a message appears and your scanner application window opens. Select different options in the scanner application window. Prompt to Scan More Pages When selected, a dialog box prompting you to scan additional pages appears after every scanning session.

This option is used to compresses and filter the images in the scanned PDF. Click the Settings icon to customize optimization with specific settings for file compression and filtering. Select an opened file from the drop-down, or browse and select the PDF file. Click the Settings icon and specify whether to create a PDF Portfolio of the files, the number of pages for each file, and a filename prefix.

This option applies optical character recognition OCR and font and page recognition to the text images. Click the Settings icon specify settings in the Recognize Text - Settings dialog box. See Recognize text in scanned documents. Add Metadata When selected, the Document Properties dialog box appears after scanning. In the Document Properties dialog box, you can add metadata, or information about the scanned document, to the PDF file.

If you are creating multiple files, you can enter common metadata for all the files. Default settings are suitable for a wide range of document pages, but you may want to customize settings for higher-quality images, smaller file sizes, or scanning issues. Click here to see all the image optimization options Apply Adaptive Compression Divides each page into black-and-white, grayscale, and color regions and chooses a representation that preserves appearance while highly compressing each type of content.

The recommended scanning resolutions are dots per inch dpi for grayscale and RGB input, or dpi for black-and-white input. Use JPEG instead. By default, the scanner application dialog box does not open.

Highest-quality levels use the lossless method; at lower settings, text is highly compressed. Compatible with Acrobat 5. Note: For compatibility with Acrobat 4. This fast, lossless compression method is compatible with Acrobat 3. Deskew Rotates any page that is not square with the sides of the scanner bed, to make the PDF page align vertically.

Choose On or Off. Background Removal Whitens nearly white areas of grayscale and color input not black-and-white input. Then, Off or Low should produce good results. If scanning off-white paper or newsprint, use Medium or High to clean up the page. Descreen Removes halftone dot structure, which can reduce JPEG compression, cause moire patterns, and make text difficult to recognize. Suitable for —dpi grayscale or RGB input or, for Adaptive Compression, —dpi black-and-white input.

The On setting recommended applies the filter for dpi or higher grayscale and RGB input. Select Off when scanning a page with no pictures or filled areas, or when scanning at a resolution higher than the effective range.

The default value is low and suitable for most documents. Increase it if the quality of the printed document is low and the text is unclear. To change the language, click Edit and choose a different language. Scanning tips Acrobat scanning accepts images between 10 dpi and dpi. Also, input resolution higher than dpi is downsampled to dpi or lower.

Lossless compressions can only be applied to monochrome images. If this image is appended to a PDF document, and you save the file using the Save option, the scanned image remains uncompressed.

For most pages, black-and-white scanning at dpi produces text best suited for conversion. At dpi, OCR accuracy is slightly lower, and more font-recognition errors occur; at dpi and higher resolution, processing slows, and compressed pages are bigger. If a page has many unrecognized words or small text 9 points or smaller , try scanning at a higher resolution.

Scan in black and white whenever possible. When Recognize Text Using OCR is disabled, full to dpi resolution range may be used, but the recommended resolution is 72 and higher dpi.

For Adaptive Compression, dpi is recommended for grayscale or RGB input, or dpi for black-and-white input. Your system may require 50 MB of virtual memory or more to scan the image.

At dpi, both scanning and processing typically are about four times slower than at dpi. Avoid dithering or halftone scanner settings. These settings can improve the appearance of photographs, but they make it difficult to recognize text. If your scanner has the color-filtering capability, consider using a filter or lamp that drops out the background color.

If your scanner has a manual brightness control, adjust it so that characters are clean and well-formed. If characters are touching, use a higher brighter setting.

If characters are separated, use a lower darker setting. Troubleshoot scanner issues.
