I am having a problem with my scanner and/or printer. When I scan a kit part that I have goofed up and print it out, the colors are off. Is there a way to tell if it's the printer or the scanner that's not reproducing colors correctly? I would hate to have to trash a model because I messed one part up; unfortunately, a very important part. Is it considered bad form to reproduce parts to facilitate completion of the model? Thanks for any input on this.
