PDF Output of a Smartform is too big

Hello,

I have a client that is e-mailing a certificate generated in a PDF format from a Smartform. The size of the PDF is 1 MB and it is causing some problem in their e-mail network.

The smartform has only some rectangles and data in it, NO picture at all.

Does anybody know how to reduce the size of the PDF output of a smartform?

Regards,
