If you're in the design business or a sign business that could use these types of raster graphics, and you don't utilize Photoshop or CorelDraw... well... you have more problems then and are stuck in the early 90s.
As the one who handles support calls for our seamless tiles, I can tell you that a significant minority of sign companies who own and use wide format printers either do not own an image editor such as Photoshop or they own a license but have not learned to use the software. Most of these folks are users of FlexiSign or Gerber Omega and expect/hope that software will handle image editing ... which, of course, it is not designed to do.
