When sending a Normalized PDF to FlexRip, the chosen screening type (for example, Groovy Screens) is not applied to a certain bitmap.


The Normalized PDF file contains a 1-bit bitmap set to Darken (Esko) overprint. When outputting to FlexRipT4 with (Groovy) Screens, the Groovy Screens are not applied. When changing the bitmap to opaque, the output is correct.


The internal bitmap is a 1-bit bitmap and hence it can be considered as a copydot.

On the dispatcher, if the automatic copydot recognition is enabled in the Queue settings > Copydot tuning, the bitmap is recognized as a copydot. Hence the bitmap does not pass through the screening module and is exposed without screening (here Groovy Screens).

If the automatic copydot recognition is disabled or if the bitmap is set to opaque, the bitmap will be contourized and passed through the screener. As a result the screening (here Groovy Screens) will be applied.

Keep in mind that when the bitmap is contourized, the whole bitmap needs to be loaded into memory and hence can sometimes lead to an 'Out of memory' error.
