How do artists make prints of their paintings?
One way of doing it is to get a really good quality digital camera and take photographs of the paintings in suitable light with the camera on a tripod and preferably using a remote button so the camera isn’t even slightly shaken. Photographs taken in raw file format can be worked much more. If you want really high quality prints, save the best versions as TIFF files, and you can always print from these. Most graphic or design studios have printers linked to computers to print from TIFF files in large formats, like posters or bigger. Depending on the size and quality, each print can cost €30 to €50 to make.
