50th Birthday & New Challenge over on Simply Create

A little break from making Wedding invites, a man 50th Birday card using Dis Digi Images, bought it a while back thinking it would come in handy sometime. Tried to colour it with Promarkers but the printer ink (even sprayed with hairspray) kept bleeding so had to go back to my Prisma pencils.  Is there a way round this, would love you to tell me. Shame as I am really enjoying the Promarkers!
