Optimization Settings in Create Adobe PDF Online

Create Adobe PDF Online provides predefined optimization settings for Web, eBook, screen, print, and press. These settings are designed to balance file size with quality, depending on how the Adobe PDF file is to be used. Adobe recommends that you use the predefined settings unless you are familiar with Adobe Acrobat Distiller; if you are familiar with Acrobat Distiller, you may want to use the Advanced Settings for optimization.

You can set a default optimization setting to use for all documents, or you can choose an optimization setting for each document you create. See below for an explanation of the preset optimization settings.

— To set a default optimization setting, click Preferences after logging into Create Adobe PDF Online. Choose an option from the Optimization Settings pop-up menu, and then click OK.

— To choose an optimization setting for each document you create:

1. Log into Create Adobe PDF Online, and then click Submit a File.

2. Select the file you want to convert, and then click Continue

3. Choose a conversion method, and then click Continue.

4. Click Preferences in the Set Options dialog box, and then choose an option from the Optimization Settings pop-up menu.

5. Click Create Adobe PDF!

Web Optimization

Web optimization creates an Adobe PDF file that is small enough for Web distribution. (You can optionally embed all fonts used in the document to preserve the fidelity of the document.) Images are downsampled to 150 dpi, allowing you to zoom in for greater detail on-screen while offering reasonable print quality. Colors are converted to sRGB for consistent reproduction across different printers.

eBook Optimization

eBook optimization uses the same settings as Web optimization, but it adds page thumbnails, which can be used to navigate the document.

Screen Optimization

Screen optimization creates a small Adobe PDF file suitable for on-screen viewing, where the exact fidelity of the document isn’t important. Since only fonts with non-standard character sets are embedded, some font substitution may occur. Images are downsampled to 72 dpi, a resolution that is good for on-screen viewing, but it may cause poor output to desktop printers.

Print Optimization

Print optimization creates an Adobe PDF file designed for printing to standard desktop printers. Files may be large if source documents contain images. Subsets of all fonts used in the document are embedded. Color and grayscale images are downsampled to 300 dpi; monochrome images are downsampled to 1200 dpi. Colors are tagged for color management to preserve optimal quality in a color-managed workflow.

Press Optimization

Press optimization creates an Adobe PDF file designed for print production, where the final output is from an imagesetter or platemaker and the printing is done on a printing press. File size isn’t considered–the file retains all the information that a commercial printer or service bureau needs to print the document. Colors are not tagged or converted; they are left unchanged. OPI comments are preserved in the file.

Note: Before you create an Adobe PDF file for print production, check with the commercial printer or a service bureau for preferred output resolution and other settings or ask for a .joboptions file containing the recommended settings.
