Hi Jörg,


your issue is normal, as you can see from the logs there is an incorrect state of the engine ... it means your document is too big and there is not enough memory available  (I think you know that for the 32bit it max 2GB) and so it is low that it leaves some blank pages (the problem is due to the burning of the image).

For this reason we have developed in the RegEdit two options :

 - ImageMemoryThreshold

 - RasterImageMemoryThreshold


Please try changing that value to 500: 


 And changing this other one to 1000



This value is combined with the possible amount of allocable memory for the process which is quite dynamic but it is almost always around 1.4gb, so you should never put a value higher than this one otherwise you will receive an exception during process.


However, when it is possible, we always recommend the 64bit version which can allocate much more memory surprised.


Have a nice afternoon!


Best regards,
