Does the halo actually output, or is it strictly a screen preview problem?
Interesting. Quite the opposite of this problem I reported several years ago:
That said, we really do need to know if this is printing and if it's also visible in Acrobat.
Yes the halo is does appear on the final PDF used for printing, and therefore does unfortunately print.
Why would RGB Tiffs in Photoshop CS6 suddenly cause this to happen. If we revert back to placing Photoshop CS5 files into Indesign, all is good.
Also it is not just an isolated event as my colleague has the same thing happening on his workstation.
Could it be that that Indesign 5 cannot colour manage the new CS6 RGB Tiff files?
CMYK tiff works well, as does PSD (CMYK and RGB)
Also please note, that if you were trying to recreate this to see if you get the samed problem, the halo occurs as soon as you create transparency with a layer mask and feather the edge of mask, and then save as RGB tiff. It will not be visible if you have a hard line or a vector edge.
Just for the record here is our set up.
Indesign CS5 (PC)
Photoshop CS6 (PC)
I think most likely it's a bug, but even if you report it for CS5 it won't get fixed. Are you willing to share one of these images that does this for testing with ID CS6? There's some hope if it still happens that it would be fixed for this versionor the next.
I haven't got ID CS6 yet. Maybe someone else could do test.
Just need to create clipping path around an object in PS CS6, then create selection from path with a decent visible feather, then apply mask to selection so surrounding area of mask is transparent.
Save as RGB tiff (with transparency checked).
Now place image into ID CS6. Is there a halo around feathered area?
Great to hear about anyones results.
I don't see it here in CS6, but my method of saving the tiff may be different from yours which is why I asked if you could share a file that is known to have the problem.
I tried the same image in CS5, and I do see a VERY thin dark line, but nothing as pronounced as your screen shot.
If you increase the feather on edge of mask, then the halo becomes more prominent.
Tried your image. Same results. Halo in CS5, none in CS5.5 or CS6.
Thanks very much, Hopefully an upgrade will fix it.
