How printing DGn files in PDF/X-1 standard.

Hi! I have the following problem. I have to print PDF in the following standard: PDF/X-1. This standard involves a series of requirements such as 1. Fonts need to be embeded in the PDF file. 2. CMYK colours or SPOT COLOURS have to be included. Is it possible to print a DGN file in this specific PDF format? Is it possible to manage CYMK colours during printing? RGB colours and INDEX colours, if converted into CYMK, do not provide typically the wished result. How it is possible to embed fonts and to map the Microstation fonts with standard fonts? Do I need some other Bentley extra Plug in or Applications to perform these operations? If all these operations are allowed how can I do this? Thanks in advance. Roberta Luccioli
