I uploaded our artwork for 3 banners. The website said the images were low resolution, but I know we designed them with high-resolution images. Upon contacting Post up stands, we were informed that Post-up Stands was having problems with the resolution-check on the website and that we shouldn't auto-enlarge them. After placing the order then, I tried following up with Post up stands (through the emails I was sent) to see if they could verify that everything looked adequate. I received no confirmation or help from the person who responded. After getting the banners, the image on one of them is quite pixelated. I had to use it for our show as I didn't have time to get a new one, but it doesn't look very professional.
