Greetings!
How do I fix the following glow of pure black items after import of RGB TIF files?

1) The target output is CMYK.
2) Will share the screenshot a bit later.
3) On the screenshot: left is the original RGB TIF image in the Windows Preview; right is the image imported to ID with black (K) turned off. So the pure black lines in the original TIF become black with light magenta glow, especially the text labels.
4) Vector is not an option for me since the image generating software cannot output to SVG, AI or vector PDF.
Thank you.

If you import RGB images of any kind and convert it uopon output to CMYK in InDesign you will always get 4c-Black.
I recommend to confert this graphic (contrary to a photo) in Photoshop to CMYK, use a personalizid conversion with maximal Black to avoid 4 black. But better would be to use an AI or PDF/X4 file. Where does the graph come from? I would avoid Photoshop with such thin lines. I am sure you have access a file where you can go the vector path instead a file with pixels.

Hi AKazak,
best provide a sample TIF file so that we can look into the issue more closely. Put it on Dropbox and share the download link. I think, this is really a job for PhotoShop and not for InDesign to prepare the image print-ready.

Additional research on the topic showed, that the glow around black lines is in place in the original RGИ images.
I assume that image producing software I used to generate the original RGB images made a kind of antialiasing or font smoothing to make text more nice to read.
Does this make sense?
