I have 3 images from a customer that are currently 6" * 10". We need to print them very large for the side of a bus. need someone to either create them in vector or increase the image quality to be able to print them 450" long. I am looking at all options, but turn around time must be quick. We print from Coreldraw so image size is a concern so can't just "resample" to a larger dpi as it won't print the file.
