RSA encryption problem

I have generated a key pair in the applet constructor and also instantiated a RSA cipher.
If I try to encrypt the same plain text two times with the public key, I obtain two different cipher texts.

What 's the problem? Could anyone figure me out? Thanks.

color printing

I have bought several A40CR cards two months ago. The cards are white blank cards.

I wonder if you can do color printing on card. I want my card to have the front print.

If yes, how much do you charge for this service?
