To resolve this issue, resample the image that is included with the publication to the appropriate resolution for the output medium. You must use some discretion and experimentation when you apply this general guideline to your specific print job.
Some printers support very high resolutions.
If you save your picture at more than 300 PPI, large pictures may take up large amounts of disk space and may slow down other operations on your computer. If the image is embedded in the publication, extract the image from the publication. Select the image that you want to extract. On the Tools menu, point to Commercial Printing Tools, and then click Graphics Manager. Click Create Link.
