USING ACROBAT 9 PRO
Saving and exporting PDFs
Specifies the type of color management to be applied to the output file and whether to embed
RGB/CMYK/Grayscale
an ICC profile.
Note: If you use the Save As or Export All Images command on a PDF that contains JPEG and JPEG 2000 images, and
export the content to JPEG or JPEG 2000 format, the resulting image may look different when opened in Acrobat. This
can happen if the images have a color profile included at the page level but not inside the image data. In this case, Acrobat
cannot bring the page-level color profile into the resulting saved image.
Specifies a color space and resolution for the output file. You can let Acrobat determine these
Colorspace/Resolution
settings automatically. To convert color images in the file to shades of gray, choose Grayscale.
Note: Higher resolutions, such as 2400 pixels per inch (ppi), are suitable only for small page sizes (up to 6.826 inches or
173.380 millimeters).
PNG options
PNG format is useful for images that will be used on the web.
Specifies if the image is interlaced. None creates an image that displays in a web browser only after
Interlace
downloading is complete. Adam7 creates an image that displays low-resolution versions in a browser while the full
image file is downloading. Adam7 can make downloading time seem shorter and assures viewers that downloading is
in progress; however, it increases file size.
Lets you select a filtering algorithm.
Filter
•
Compresses the image without a filter. Recommended for indexed-color and bitmap-mode images.
None
•
Optimizes the compression of images with even horizontal patterns or blends.
Sub
•
Optimizes the compression of images with even vertical patterns.
Up
•
Optimizes the compression of low-level noise by averaging the color values of adjacent pixels.
Average
•
Optimizes the compression of low-level noise by reassigning adjacent color values.
Paeth
•
Applies the filtering algorithm—Sub, Up, Average, or Paeth—best suited for the image. Select Adaptive
Adaptive
if you are unsure of which filter to use.
Specifies the type of color management for the output file and whether to embed an ICC profile.
RGB/CMYK/Grayscale
Specifies a color space and resolution for the output file. You can let Acrobat determine these
Colorspace/Resolution
settings automatically. To convert color images in the file to shades of gray, choose Grayscale.
Note: Higher resolutions, such as 2400 ppi, are suitable only for small page sizes (up to 6.826 inches or 173.380
millimeters).
TIFF options
TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications.
Resolution is determined automatically.
Specifies a compression format. CCITTG4 is the default and generally produces the smallest file size.
Monochrome
ZIP compression also produces a small file.
Note: Some applications cannot open TIFF files that are saved with JPEG or ZIP compression. In these cases, LZW
compression is recommended.
RGB/CMYK/Grayscale/Other
Specifies a color space and resolution for the output file. You can let Acrobat determine these
Colorspace/Resolution
settings automatically. To convert color images in the file to shades of gray, choose Grayscale.
Specifies the type of color management for the output file.
