I recently had a request to do several 6 foot and 12 foot banners (something I just don't do) and wanted to help out the customer, so agreed to do it. I got a roll of LexJet TOUGHcoat™ ThriftyBanner (42 in x 40 ft) and had to make a quick decision about a profile, so I downloaded the HP Polypropylene Matte profile from HP's website and loaded the vinyl and calibrated. I tired to profile and it wouldn't let me. Tried it several times and had to restart several times. I'm guessing it was because the Lexjet media is 16 mil and the HP media is only 7 mil.
Anyway, I had promised the customer a rush job, and went ahead and used the canned profile and they came out well - no problems, particularly as I had disabled the cutter in the profile properties.
Later, Lexjet suggested I download and try the HP Opaque Scrim preset, to see if that would be an improvement.
Before doing that, thought I would ask, yet again, for opinions and approaches, prior to running another unknown preset.
