Hi all. I am printing on lexjet velvet pro, which is a 15oz. commercial grade wallcovering. I'm printing out of caldera on the Epson S70670. I was wondering about the tension check setting. It gives me the option to check Periodic, Every Page, or Off. I'll be honest, not even sure what these mean. so I'm not sure which one to go with. Does anyone have some advice for me?
