Yes. Ink should be fully dried and cured before it is sealed beneath a pressure-sensitive film. Trapped solvents or moisture can cause bubbles, haze, edge lifting, or adhesive changes. Drying requirements depend on the ink, printer, media, coverage, ventilation, and humidity. Heavy solid colors may need longer than light graphics. Keep prints exposed to circulating air and avoid tightly stacking them immediately after printing. Test one finished piece before processing the entire job.
