The Nitro PDF Creator Printing Preferences dialog

• Target Folder: Set the default location where new PDF documents are stored, or click … to browse for a folder
• If file exists: Specify what to do if a new PDF is saved to a location that already contains a PDF with the same name
• Version: Set the version of the official specification Nitro PDF Creator will use when creating PDF files
• Compliance: Define if files should be created as standard PDF files or archival-grade PDF/A-1b documents
• Conversion Quality: Select a standard for image resolution, compression and quality, and for font embedding. File size increases as you increase the quality. Use the Custom option to define your own parameters for images and fonts. Web ready: Optimizes the PDF file size for browser viewing and fast downloads. Office Ready: Optimizes the PDF file quality for satisfactory office / personal printing results. Print ready: Optimizes the PDF for maximum quality when processed on professional printers. Custom: Allows you to configure the following PDF output settings manually:

1. The Images section allows you to specify custom settings for image optimization. Depending on the types of images in your document, you can choose from the following options:
2. Downsample: Sets the number of dots per inch when rendering each image. Lower numbers reduce the quality of your printed images, and also reduces file size.
3. Compression: Sets the type of compression to use in compressing images. If Automatic is selected, Nitro PDF Creator selects the best compression type to suit the majority of images within the document. You can also experiment with different settings to find the optimal balance between file size and image quality.
4. Image Quality: Select JPEG compression to specify the desired image quality, depending on the intended use of your document. Higher image quality results in larger file sizes.
5. The Fonts section allows you to specify custom settings for font embedding. 
6. Embed (subset): includes only the portion of characters for each font that are required to properly display the document. If text in the PDF document needs to be edited in the future, some characters may not be available, but the file size is smaller than if full font is embedded.
7. Embed (fullset): includes the complete character set for every font in the document, making fonts available if the PDF needs to be edited in future. Full embedding also increases file size.
8. Do not embed fonts: Embeds no font information in the PDF file. This creates the smallest file size, but may alter the appearance of the PDF file when viewed on computers that do not have the same fonts installed.
9. If embedding fails: Specify whether to proceed with creating your PDF file if the fonts cannot be embedded
10. Close the progress dialog when the conversion has finished: To automatically close the process window when PDF creation is complete, check this checkbox
11. Open using default application after creation: Automatically open a newly converted PDF file in the default PDF viewer

• 40-bit ARC4: Use this if you need compatibility with old versions of Adobe Reader
• 128-bit ARC4: Stronger than 40-bit ARC4 encryption
• 128-bit AES: More advanced encryption than ARC4
• 256-bit AES: Highly recommended, and used by latest versions of Adobe Reader
