Thanks for your advice. Currently I'm using Acrobat Distiller for conversion to PDF. First my word document should be converted to PS and it must be passed through distiller for PDF. While doing so, some part of the text particularly in images are missing. I have tried this with different systems. In some system, it is okay. But in most of the system, we got this error. I think some settings in the word options were changed. Is it possible to fix it? Thanks for your help.
