COLORING CATASTROPHE

[yair3777338]

I designed a brochure in Corel 11 and when I pdf it, it totally changes the color (this didnt happen when I pdf'd it a few weeks ago)

I also opened it up in corel 3x and the colors again completely changed this time even before I pdf'd it (just by opening in up in corel 3x)

the color changes are similar both times

Is there any settings that I can check to ensure that this doesnt happen? Its very urgent as I need to send this to the printers tomorrow and my client needs this right away.

Any help and advise would be much appreciated.

With many thnax

If you are intending to to go to press and it is a spot colour job ensure you use the Pantone pallett same applies to cmyk also ensure your colour manager is set to cmyk. In Publish to pdf ensure the colour choice is set to 'native'
If it is just to printed on a desktop inkjet the RGB is ok and let the driver do the conversion at print time. I am assuming the colour manager is on, having this off will give you very bright vibrant colours on screen which almost certainly will not reproduce at print time certainly not when going to press.
You may find the the colour manager section on the Corel News Group an interesting read and you can always post questions there, far more knowledgeable people than me take part.
