Ground Controls->Non_PDF->Images->File Status
These Ground Controls are designed to give you feedback on the state of images used in a document.
Missing - This Ground Control will trigger if an image used in a document cannot be located. Usually this results in the low resolution preview image being imaged to plate or film instead of the the crisp clear high resolution image.
Modified - This Ground Control will trigger if the last modified date of an image does not match the date of the link data saved within the document being scanned. A modified image may indicate that an image has been altered and may not match the original intent of the job.
Stored - This Ground Control will trigger if an image has been stored or embedded within a document. InDesign, Illustrator and PageMaker can embed images, whereas Quark only deals with linked images. EPS files can also have images embedded or stored within them. Stored images can be difficult to extract from files and many people in their workflows do not want to deal with embedded images, they only want linked images.
Nested - This Ground Control will trigger if an EPS file that has a placed image inside of it (i.e., the images is linked to the EPS and not embedded in it).
ASCII Data - Will fire if an image has been ASCII encoded. Depending on your workflow, this may or may not be a problem.
Binary Data - Will fire if an image has been Binary encoded. Depending on your workflow, this may or may not be a problem.
LZW Encoding - LZW is a compression scheme. This Ground Control will trigger if an image has been compressed using the LZW method. Some RIPs have problems handling LZW encoded images
JPEG Encoding - JPEG is a compression scheme. This Ground Control will trigger if an image has been compressed using the JPEG method. Some RIPs have problems handling JPEG encoded images.
