I'm looking for 20 decals printed on clear with the attached art, (customer supplied...) They will go inside car windows, so I either need the white printed, or I can apply white vinyl later. I have a Summa printer, but my new print-head won't print on just any clear! Since I've printed on clear maybe 6 times in 10 years, I hesitate to buy a Summa roll for $300.00. Any help appreciated!
