Jason Black, President at Southern Graphic Machine, does not honor contracts. CAUTION USING SOUTHERN GRAPHIC MACHINE to move any if your printing equipment. He doesnt pay his bills and his practices are unsafe, such as lift trucks rolling off the back of semi-truck. Steer clear if this company. Jason Black hired my company to finish an installation and perform a machine start up, that his employees couldn't handle. After completing the project successfully and obtaining a sign off from the user, Jason refused to pay us. In fact he wont answer phone calls, emails or letters. Steer clear of Jason Black & Southern Graphic Machine. So untrustworthy, I'd not take a chance with any of the rebreather equipment he sells in the Diving community.
