CMYK colours differ between mac and pc

[jennyflower]

Hi, I am creating a banner to be published professionally. We have standard colours that we use when creating anything that is published but these have all been created using photoshop on a pc. The company we're getting these banners printed with need it done on a mac so im using photoshop on my mac.

The only trouble is one main colour we are using has the # number of cc6600 and CMYK value of 16, 69, 100, 4 on the pc but when I use the same CMYK value on mac photoshop the # value is cb6828.

Which values should I use or is there a colour setting I should use so when printing the colours will come out the same?

Thanks

'cc6600' refers to a web color. Ignore that.

Lab color mode is consistent. Try that.

Also check your color management settings on each computer.

There should be no difference between Mac and PC versions of Photoshop. Unless you are using an ancient version, you should be able to send a Photoshop PDF file to the banner printer. The Photoshop PDF file will include the fonts.

...as jimoblak mentions, depending on your colour management settings in adobe apps the colour cc6600 will seperate into cmyk differently if the setups are different on comparable machines...

...the colour cc6600 will in truth look different on one computer to another on the web in anycase...

...if you have a specific pantone reference colour you would be better off sticking to that really or stick to the specific cmyk values you have been given...

...it is also worth mentioning that same colour values look different on different substrates...

...colour management is a real can of worms and is sold to many as scientific perfection when in truth it isn't really, that is not to say that colour management doesn't work, it just needs a lot of understanding into how devices produce or capture colour. Then you have to look after these devices to control their known status. This often means spending a good deal of money on calibration hardware/software to get anything like a decent result...

Thanks guys, at least I think I understand it more now. Ive stuck to CMYK colours but cannot use pantone as the printers dont allow it but apart from that I think Im set

Thanks again
