The easiest way that I've found for the customer to comprehend
and make my life simple, is velcro strips on the main banner and a separate "date banner" that
they change out for the following years.
As you've suggested, I've worked trying the area on the banner that is reserved for adhesive vinyl dates. I've tried a color block for dates and then used white repositionable vinyl. All worked great and were the perfect solution ...for the first year. Then, the banners were folded, stuck in a box, mold set in, the event chairperson's cat peed on them, a squirrel ate the grommets. ...name any excuse how the banners survived a zombie attack. And then, it became my responsibility to clean up the neglect and abuse, and change the vinyl on the day that the banner was to be installed --- while the customer waited. [/rant]
Yes, I urge you, plead with you, use velcro. Or next year, you'll stab yourself with an X-acto knife because you didn't head this warning.
Sooooo, if you choose to ignore that previous warning, figure out a way to do the banner in cut vinyl. That way the solvents and cleaners you use to remove vinyl adhesive, mold and cat urine, won't wipe your print off.
annnnd, if choose to ignore that warning, laminate the printed banner so the solvents and cleaners you use to remove vinyl adhesive, mold and cat urine, won't wipe your print off.
Good wishes!
