Convert color tool in Acrobat causing jpeg-like artifacts in image

Hello. We recently had a PDF from a clinet that we needed to convert to CMYK. We used the PrintProduction>Convert Color tool to have all rgb converted to GRACol2006 profile. When we ran this, the images would degrade, as if they were downsampled and resampled up like a jpeg. Visible artifacts appeared all over the images. If we edited the images in PS, and converted to CMYK, they were fine. We tried this on multiple desktops, Mac and Win, same result. Has anyone else had this issue?

I've had the same issue. I'm looking for a solution.

Apparently there is no interest in fixing this. Adobe does not monitor these posts (unwisely , in my opinion) and forces those with real program issues (not the basic new user questions) to go through their tedious bug reporting site. As another user mentioned above, you can use Pitstop or Photoshop to do this, but why would Acrobat's color managment engine damage images? The whole thing is Adobe's code.

For my two cents the above reposnse on asking a client to do this in their original, it is not customer friendly.

I don't give much credence to the color conversion in Acrobat. There is usually problems. PitStop will do much better, or tell the customer to do it in their file creation program.
