We use a 3 colour print process using Pantone 286 (Blue), Pantone Warm Red and Process Black. Occasionally we receive PDFs that have used Pantone Process Black instead of pure Process Black so in Quark when you separate the colours you get 2 black plates. Is there a quick way to change the Pantone Process Black to Quarks Process Black? Because it's in a PDF you can't delete the colour and replace it with Process black (essentially 'Find and Replace'). You get a message saying it won't separate correctly then just deletes the colour giving no option to replace. Any ideas? I can separate the whole thing myself using Photoshop but it is going to take ages as its a complicated advert. Thanks.
