A Link is the original file for any image you used in your publication but did not create within that publication. Our computers must be able to locate and refer to the original image file when translating the data to our printers. If the link is not found, there will be errors in the translation; your publication will not print correctly. This is true even though you may have used a “complete copy” of the image file in your publication. Submit editable copies of these files, so that adjustments can be made for trapping, knockouts, etc.
After you have imported an image into the publication, do not rename the link without updating the links in the page layout application.
If high and low resolution images are on the same disk, make sure the links are to the correct images.
