changing out of gamut colours
Hi all
Sending a poster off to print and I've got a gamut warning on a colour.
I've selected the colour with the colour picker and the warning trianle has come up in the colour palette. I've clicked it to obtain the nearest CMYK equivalent and nothing happens.

Does anyone know what I'm doing wrong?

Chris

Re: changing out of gamut colours
Hello Chris,
I've just tried it out and when I have clicked on either the warning triangle or the small colour box just beneath the triangle, the colour picker has jumped to the closest equivalent.
What I have never noticed before is in View if I click on gamut warning the colours out of gamut are grey. This may be a CS3 thing or just something I've never clicked on before!
Hope this helps,
Deborah

Hi Deborah
That's how gamut warning works in CS, too, but colour picker still won't jump to nearest cmyk. Don't know what I'm doing wrong but thanks anyway!

Re: changing out of gamut colours
There are several ways to change out of gamut colours in your image. The colour picker will really only work when you're choosing a new colour, say for text or to paint with; it won't help you to change colours already in the image.

You could try using Hue/Saturation, choosing the colour from the pop-up list that most closely approximates to the colour you're using, then refining the selection with the sliders. Drag the Saturation slider down, switching CMYK Preview mode on and off (ctrl/command Y) to see the difference. Alternatively, Replace Color can be a good way of doing it.

A more drastic approach would be to change the document to CMYK mode (which will take out all the out of gamut colours) then change it back to RGB. Not sure I'd recommend this method, though, as the two colour changes can only help to degrade the image.

It really depends on how much rogue colour there is in the document. If it's only in a couple of small places, I wouldn't really worry about it - it's not like it's going to damage the printer, or anything. Check it with CMYK Preview and, if it looks OK, just send it off.
