Spent 18 months printing everything in RGB mode and a Best Buy tech caught it in 30 seconds
I was at the counter in Minneapolis picking up a monitor when the guy glanced at my test print and asked why my oranges looked like burnt mustard. Turns out I had been exporting flyers in RGB the whole time, so my printer was guessing at colors and guessing wrong. The tip off? A stack of 200 posters for a record store came back muddy brown instead of the hot coral I picked, and the shop blamed my file. Switched to CMYK with a soft proof and now my oranges actually pop. What is the dumbest setting mix up that took you way too long to spot?
