The TransparencyHalftone user parameter has two allowed values: /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.
