Yes, it might be a good idea to check your rendered image inside a program such as Photoshop and check for colors that will be out of gamut. Since Poser only uses RGB and offset printers require CMYK, there might be a few problem areas. Might. That depends on the press and whether it's a 4 color or 6 color (some presses use orange and green inks now, in addition to the standard cyan, magenta, yellow and black).
