Photoshop CMYK help

I need your expertise

I have made the artwork for printing using Photoshop in RGB mode. I was very happy with the colours, but was then told by the printers that I must submit the file in CMYK mode. When I changed the mode to CMYK some colours became much less vivid in my main logo. I'm not sure I fully understand Photoshop's explanation of out-of-gamut colours. How can I make these colours vivid again?

Thanks....

There's a way however, just use adjustments curves or levels. Its not very scientific but it works for me:)

you'd be here all day explaining why etc. But to get it done, do what phelen says and play with levels, curves, saturation etc.

crikey, i hope this job is for yourself and not a client. it's all about pantone specification, and not using photoshop as a layout tool.

good luck Smiling

you will struggle with some colours as they are not available in CMYK

and with stuff like this you should really start with CMYK

If its a logo, it should in its original format be produced using Pantone colours. Use your Pantone/Process color book to get the CMYK values and replace the colours.

[edit] If you give me the pantone colour references i'll post up the CMYK equivalent colours?

try converting the image to black and white, if the lines are bold enough you should still be able to see the main outline and could then play about with the attributes?
