The copy you have should match what is on file.  If they don't, however, your remedy is to request andreceive a clearer version of the ticket so that you can properly defend yourself.  From there you can make the decision of whether to pay or contest the ticket.  This mismatch is not automatically a basis for the ticket getting dismised.  It can be evidence, however, that the officer may not have been as diligent in his ticketing practices and could form part of your defense to the ticket.
