Thank you all for the info. Sorry, but my English is very bad. And I am not a real PDF Expert. InDesign has a very goood type management. In the type management I saw that same types are defect or misssing. And as I said I changed them in pictures and then PDF writing in INDesign worked. I opened the PDF in Photoshop in High resolution with 500 dpi so the quality was good. From the technical support came the advice to open it in Preview and change it in a picture. I tryed it but the only possibility I saw was a screenshot. This is from the resolution not good enough. So it is no solution the problem. With the cleaned PDF (5 ads from hundreds) PDf writing worked in InDesign. So I opened the cleaned IDML in Publisher and tryed PDF writing but it didn't work. I must say I have many clients which have really no idea from professionell PDF writing.
