The TransparencyHalftone user parameter has two allowed values of: /Default , to use the page default screen for non-fully opaque objects, and /TopMost , which uses the screen from the top-most object for all objects. In all cases, fully transparent objects are ignored.

The /Default behavior is in-line with the PDF specification.

The /TopMost setting is of particular value in workflows where it is important to use halftones specified in the supplied PDF file, such as flexography.

Note: If screening overrides are used, the values from the overrides will be used in preference to those from the job.

Note: Overprinted objects may use a combination of screens for foreground and background objects, where overprinted colorants will use the screen from the background object.
