So, there's Image A, which the yellows print fine for, and Image B, which the yellows don't print fine for, correct? A few questions:
1) What program are you printing from?
2) Are you using the same printer driver, on the same paper, with the same printer profile, and the same color settings, for both images?
3) Is it just Image B where the yellows don't print right, or are there other images where the yellows don't print right? If everything is always OK except for Image B, then there's something about Image B. If it happens with other images, too, then there's something about your print settings/printer profile selection/etc.
Sometimes when you dig into the tabs in the printer driver, you'll find that the settings are one way for one file, and a different way for another file. Make sure that both image files have the same exact settings as far as paper type, print quality, and so on.
One more question: do both images have the same embedded color space? For example, is one sRGB and the other one AdobeRGB? Maybe when you're importing one or the other into Photoshop, it's converting the colors from one color space to another. Another thing to check: Is one an RGB image and the other one a CMYK image?
Another question...Do both yellows for Image A and Image B look identical on your screen (but print differently)? Or do the yellows look different on the screen as well as print different?
When you say "color code," I'm assuming you mean the RGB value, correct?
I'm throwing a lot of stuff out there to see if something helps. Let me know.
