Does anyone have any suggestions on how to get proper blues and grays? I have been printing without issues for quite a while but my last projects came out with off color to the point I had to run to the closest Kinko place to print the presentations I was working on. the blues come out purple and the grays brownish. If I do a Troubleshooting from the printer, the colors come out nice and perfect, but when I send a doc. to print I don't get the correct colors.
