Black Color Not Matching When Printed

[Michael28449246zhsg]

Hello, 

I'm trying to print a pdf from InDesign. I've placed some images with a black background onto a page with a black background, so it appears the images have transparent backgrounds. I previously had a problem with the cmyk / rgb colors not matching up when I saved the pdf (i.e. the image has a different color black than the black placed in Indesign), but I fixed that. However, this is happening again from the same file when printing. I even went into the linked image and completely got rid of the background, assuming that would fix the problem. However, the issue still persists. I looked in the links panel and even when I convert the images to cmyk in photoshop, they still are listed as being in rgb. I've tried messing with many settings and I'm not quite sure where to go at this point. Any help would be appreciated.

Thanks

Hard to know what's happening without some detailed screenshots on what you're doing.

Hi @Michael28449246zhsg , As long as the placed object is an image, and the image’s embedded profile matches the InDesign document’s assigned profile; InDesign’s Eyedropper tool will accurately sample the color mode and values from the image. Here I have a selected rectangle behind the image, and I’m sampling the image background in order to get a match—the Separations panel show the CMYK output values match:
