Nope ~  You are good to go!  Fill that pool up or put your characters in a heavy rainstorm-- you'll be pleased to know (and comforted) that your talent will not have to go to makeup inbetween takes cause our high quality full prints (and fillers) don't bleed.  They won't bleed on your clothes, face, hands or other props.  Furthermore, the process following the printing of the prop money includes a heat dry and re-wet before the bills are even shipped to your set.  Not only is this to ensure solid ink no matter the weather application but also ages the bills for more authenticity in replicating real bills for film.
