Create PDF from Scanner
Nitro Pro 9 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 individual
pages or entire documents in one process. If required, you can also merge different documents to create
a PDF document compiled from various paper sources.
To scan paper documents to PDF:
1. On the Home tab, in the Create group, click the PDF button, then hover your mouse over From
Scannerto access the sub-menu
2. Click Single Scan, and in the Single Scan Settings dialog select your scanner, the sheets to scan,
image compression, and then specify the destination
3. Click Scan to open your default scanning software
4. Select the scanning mode - color, grayscale, or monochrome/black-and-white
5. Select the menu command to return to Nitro Pro 9
6. 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 Pro 9, 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 do not need to modify the monochrome settings as they
will not affect your image.
1. Color/Grayscale
l JPEG: The main Joint Photographic Experts Group standard achieves 10:1 compression
ratios with little perceptible quality loss
l JPEG2000: Achieves higher compression ratios than JPEG, and uses both lossy and lossless
compression in the same file stream
l ZIP: Uses the ZIP compression algorithm to reduce the image size without affecting quality
2. Monochrome
l CCITT Group 4: A fax document transmission standard which uses advanced compression
methods for lossless reproduction
l CCITT Group 3: The Group 3 standard achieves less compression, and is less advanced than
the CCITT Group 4 method
l Run Length: Particularly effective on files that contain many long runs of the same bit, value,
or character. This method is primarily used on binary files
l ZIP: Uses the ZIP compression algorithm to reduce the image size without affecting quality
3. Quality
l 150DPI: Might be suitable for use on the web due to the smaller file size produced, however
will not produce high quality prints
l 200DPI: Suitable for higher quality viewing on computer monitors
l 300DPI: The standard generally used for office quality prints, and generates slightly larger
file sizes
l 600DPI: Generates large file sizes, however it is recommended for high print quality of the
image
