Creating PDF from a scanner

Nitro PDF Professional provides you with an easy way to convert your paper documents to digital form for easier storage and access. Depending on the type of scanner you have, you will be able to convert pages one at a time, or do whole collections of pages in the one process. If you need to, you can also merge documents as you go to create the one complete PDF document.

To scan paper documents to PDF:

1. On the Home tab, in the Convert group, click the arrow below Create PDF .
2. Click Create PDF From Scanner .
3. In the Create PDF From Scanner dialog, select your scanner, the sheets to scan, image compression, and then specify the destination.
4. Click Scan to open your default scanning software.
5. Select the mode of scanning-color, grayscale, or monochrome/black-and-white.
6. Select the menu command to return to Nitro PDF Professional.
7. Select the Finish option to end your scanning job, or select the Scan front of sheet two to continue scanning.

Image compression settings

When scanning to PDF with Nitro PDF Professional, the type of compression used-color, grayscale, or monochrome-is determined by the output setting you select in your default scanning software. Therefore, if you intend to do a color scan, you can just leave the leave the Monochrome list setting as None.

• Compression level slider. The slider gives you quick control over how much compression to apply to your scanned pages, with the basic principle being that the lower quality you choose, the less dots per inch (dpi) and the smaller the file size will be. Approximately 50% will compress images to 96 DPI (fine for viewing on-screen), 60-70% will compress them to 150 DPI (fine for printing), 80+% will compress them to 300 DPI or higher (reasonable for high quality printing and archiving).
• JPEG Compression. Designed for photos and other graphics with very smooth and detailed tone changes.
• CCITT Group 4 Compression. Designed for monochrome or black-and-white images, it suits the scanning of plain text documents, faxes, and so on.
• JBIG2 Compression. Designed for monochrome or black-and white images, it suits the scanning of plain text documents, faxes, and so on. Pages scanned with JBIG2 compression tend to be smaller than CCITT Group 4 pages, but they take longer to generate.
