My understanding is that when a printer manufacturer specifies a drying time, it has been in conjunction with a specific media manufacturer and sometimes a specific media. It appears that the link to the S-Series brochure is for Avery Media, not a specific media of thiers which I would imagine varies greatly. OKI Colorpainter claims the same 6 hour drying time with SX inks on Avery wrap media and Avery will back it with the ICMS warranty. I've never seen 3M mention anything less than 24 hours drying time in my experience. On the OKI 3M Traffic M64s - 3M does warranty the DG and HIP for instant lamination for the Traffic MCS Warranty, but there is a infrared heater with a control box which accomplishes this.
