The resolution setting for color and grayscale images should be 1. The resolution for monochrome images should be the same as the output device, but be aware that saving a monochrome image at a resolution higher than dpi increases the file size without noticeably improving image quality.
Images that will be magnified, such as maps, may require higher resolutions. Resampling monochrome images can have unexpected viewing results, such as no image display. If this happens, turn off resampling and convert the file again. This problem is most likely to occur with subsampling, and least likely with bicubic downsampling.
The following table shows common types of printers and their resolution measured in dpi, their default screen ruling measured in lines per inch lpi , and a resampling resolution for images measured in pixels per inch ppi.
For example, if you were printing to a dpi laser printer, you would enter for the resolution at which to resample images. Downsample Off. Reduces image resolutions that exceed the For Images Above value to the resolution of the output device by combining pixels in a sample area of the image to make one larger pixel. Average Downsampling To. Averages the pixels in a sample area and replaces the entire area with the average pixel color at the specified resolution.
Subsampling To. Replaces an entire area with a pixel selected from that sample area, at the specified resolution. Causes faster conversion time than downsampling, but resulting images are less smooth and continuous. Bicubic Downsampling To.
Uses a weighted average, instead of a simple average as in downsampling to determine pixel color. This method is slowest but produces the smoothest tonal gradations. Applies compression to color, grayscale, and monochrome images. For color and grayscale images, also sets the image quality. Anti-Alias To Gray. Smooths jagged edges in monochrome images. Choose 2 bit, 4 bit, or 8 bit to specify 4, 16, or levels of gray. Anti-aliasing may cause small type or thin lines to look blurry.
Compression of text and line art is always on. To turn it off, set the appropriate Distiller parameter. Opens the Image Policy dialog box, where you can set processing options for Color, Grayscale, and Monochrome images that are less than the resolutions you specify. Fonts that have license restrictions are listed with a lock icon.
If you select a font that has a license restriction, the nature of the restriction is described in the Adobe PDF Options dialog box. When you combine PDF files that have the same font subset, Acrobat attempts to combine the font subsets. Embed All Fonts. Embed OpenType Fonts. Embeds all OpenType fonts used in the file, and maintains OpenType font information for advanced line layout. This option is available only if either Acrobat 7. Specifies a threshold percentage if you want to embed only a subset of the fonts.
When Embedding Fails. Always Embed. To embed only certain fonts, move them into the Always Embed list. Make sure that Embed All Fonts is not selected. Move fonts that you do not want to embed to this list. If necessary, choose a different font folder from the pop-up menu to display the font in the font list. If you select a font with a license restriction, the nature of the restriction is described in the Adobe PDF Options dialog box.
If the font you want is not in a font folder, click Add Name. A TrueType font can contain a setting added by the font designer that prevents the font from being embedded in PDF files. Removes a font from the Always Embed or Never Embed list. Acrobat does not include the Times, Helvetica, and ZapfDingbats fonts. Settings File. Lists color settings, including those used in graphics applications.
Color Management Policies. This menu is available when None is selected in the Settings File menu. Color Management Policies values may affect a PDF differently depending on the compatibility setting you choose in the General panel. Leave Color Unchanged. Leaves device-dependent colors unchanged and preserves device-independent colors as the nearest possible equivalent. This is a useful option for print shops that have calibrated their devices, have used that information to specify color in the file, and are only outputting to those devices.
Tags ICC profiles in images only not text or vector objects , which prevents black text from undergoing any color shift when distilling Acrobat 4. Calibrates color, making it device-independent. Recommended for PDFs that will be used onscreen or with low-resolution printers. All Working Spaces must be specified. Document Rendering Intent. Choose a method to map colors between color spaces. The result of any particular method depends on the profiles of the color spaces.
For example, some profiles produce identical results with different methods. Acrobat also includes a rendering intent called Preserve, which indicates that the intent is specified in the output device rather than in the PDF. In many output devices, Relative Colorimetric is the default intent.
In all cases, intents may be ignored or overridden by color management operations that occur subsequent to the creation of the PDF file. Working Spaces. Choose a profile to define the color space of all grayscale images in files. Choose None to prevent grayscale images from being converted. Choose a profile to define the color space of all RGB images in files. Choose None to prevent RGB images from being converted. Choose a profile to define the color space of all CMYK images in files. The default is U.
Choosing None for all three working spaces has the same effect as selecting the option Leave Color Unchanged. Retains these settings if they exist in the PostScript file. Black generation calculates the amount of black to use when reproducing a color. Undercolor removal UCR reduces cyan, magenta, and yellow to compensate for black generation. When Transfer Functions Are Found. Specifies how to handle transfer functions in PDFs. Transfer functions are used for artistic effect and to correct for the characteristics of a specific output device.
Deletes any applied transfer functions. Applied transfer functions should be removed, unless the PDF is to be output to the same device that the source PostScript file was created for.
