How do I optimise the print quality of images embedded within PDF files?
In order to maintain files at a manageable size, images embedded within our PDF files are created at a resolution which provides a balance between quality and usability (that is, the time and memory required to download and/or print a file). The quality of the printed PDF images is directly related to the resolution of your printer. In order to maximise printing quality, Adobe recommends that you use a postscript printer. • If you have a printer with a resolution of 600 dpi or greater, you will be able to maximise the output quality of the image. • If you are using a printer with a resolution of 300 dpi or less, you will not be able to print an image while maintaining its quality. • The print quality of images also depends on the type of paper used. Check your printer manual or service bureau for the best possible grade of paper that is compatible with your printer.
