Then, use Adobe Distiller and import the all EPS files.
Now select option 'High Quality Printing' in Distiller and export the project on your selected destination.
Exported file will be good for printing.
If you are exporting EPS from your corel draw then you will not have these problems, like:
- Font looks corrupt in exported pdf
- Some objects are missing in pdf while exporting
- Quality of pdf is not good for printing
- File is corrupted while exporting pdf file
If you want to know more about CorelDraw solutions, you can write me your question in the comment option. I'll create a tutorial especially for you.
Thanks for your time.
