I have been working for 2 days to get a job printed on foamboard. I think they are the only print place in the country that doesn't have the Abobe programs...so I made a PDF. If you upload online, it automatically sizes to the board you are printing on instead of the size you made it. When I tried to give them the artwork off a flash drive, they looked at me and told me I had to do it online. I tried to explain the sizing issue and they looked at me like I had 3 eyes. At that point I just gave up. If you are printing off Canva, go for it. But, if you have serious printing, don't go here. THEY DO NOT HAVE A CLUE!
Recommendation: Go somehwere else.
