Re: [PRODIG] rgb to cmyk conversion

[Ron Jones]

Many thanks to Thomas Holm, Stephen Marsh, Jan Rossee and Philip Mobley for their most helpful suggestions - much food for thought there!

The rgb to cmyk conversions I had in mind were destined for printing presses. In that respect, whilst I've seen the startling results of Hexachrome printing, none of my printers are geared up for it so that suggestion is out.

I suppose I was being lazy and looking for a quick fix. For example, I'm doing a job at the moment - a prestigious 60 page A4 4-colour process brochure containing over 250 images supplied by about 90 different organisations. 90% of the images are rgb, in a variety of formats including small gifs and even images embedded in PDFs! - a colour management nightmare! Incidentally, is it possible to extract an image embedded in a Word document and work on it in Photoshop?

Most of the suppliers haven't a clue about the difference between rgb and cmyk otherwise they would have supplied me with cmyk files, right? They certainly haven't heard of out of gamut colours and may wonder why their images with all those screaming oranges, purples and lime greens don't appear in print they way they did on their computer screens. But with deadlines looming, I think I'll revert to my quick and dirty Photoshop conversion practice. By the time the job comes round again next year I hope, with the help of PRODIG members, I'll be more colour management savvy!
