I dont particularly own a DLP, if you want for big size, solidator might do the job. But their contact support freaking blow. Emailed them 4 times and never got a single reply. My boss called them, and they basically said, yea yea we will have one of your salesman contact you. Never heard of them again....

By the way what's you're largest print you have ever done? Also, what do you usually print the most when it comes to size?
I might have an idea or 2...
