I have a brand new Canon Pixma IP5200. I am getting fantastic 8x10 prints--they are sharp, detailed, and the colors right on. But my 4x6 prints are not nearly as sharp and detailed, and have a slightly more yellow color. I havent tried to fix the color balance because anyway the prints simply are not sharp! They look like they have had a slight soft-focus filter applied. I am using 4x6 Canon Pro glossy paper. My 8x10 is matte. It doesnt make sense to me that this could account for the difference in quality, since the 4x6 paper I am using I know is the best Canon paper! Every other setting is exactly the same, and the problem exists whether I choose the default "Best" setting, or the Q1 highest-quality setting. Does anyone have any idea why I am getting such a big difference in quality?
