I designed a flyer in Photoshop, consisting of bright text over a dark stock image, and tried to print it on my own printer to get some idea of what it would look like when professional printed. However, when printed the dark background of the stock image can only be described as very muddy, to the point of being barely visible, even while the text itself stands out fine.
The Photoshop document is CMYK and was exported to PDF for printing, and looking at the specs for the printer, it seems to support CMYK, so it doesn't seem that a conversion from RGB is happening here.
Is this a design problem, and therefore something that's likely to crop up when taking the design to the printer, or something else?
