Colour shift!

[annc]

Got a full page advertisement from a local design house (PC-based, bloke uses CorelDRAW, although I haven't contacted him about this, so it's just vaguely possible he used something else) as a CMYK JPEG. I've had his ads before and they're a breeze to deal with. Also got a logo for a local shop from him, and it's perfectly behaved.

There was no printout accompanying the ad, which looked a little dark when I placed it in InDesign (Mac). Because it was already CMYK (one of the few I get) I didn't open it in Photoshop. I just resized it to fit the page, and went on to the next page, although I can remember thinking it was a bit dark.

Anyway, I sent off the colour proofs to the client, and got a frantic phone call today, saying that there was something badly wrong with my colour proofing system, and that the problem was with this ad.

Deciding to go to the original file, I double-clicked the file on the floppy. Quicktime decided it owned the file, and showed what you see in Attachment 1.

I then looked at the page in InDesign, which showed what you see in Attachment 2. Huge colour difference.

So I opened the file in Photoshop, which can be seen in Attachment 3. It turns out that this was what I should have been seeing all along.

When I saved the file out of Photoshop as a Photoshop file and placed that in InDesign, I got what I saw in Photoshop.

None of my equipment is calibrated, but I doubt if this is the problem. I haven't changed any of my colour settings in InDesign or Photoshop, and the other files I've had from this studio have no colour problems whatever.

Anybody got any idea what's causing this?
