Adobe RGB V sRGB

[JMugs]

If I am sent an image which has been through PS converted from Raw to RGB, but I am printing in sRGB (can a a printer really do RGB) could it cause a slight colour shift?

I have been reading for hours, and so many people argue about it. I then find a PDF and that was so far over my head (for now anyway) that I was lost.

My line of thinking is "yes".

Comments welcome.

You should have have your workspace set to Adobe RGB 1998 (this is a good one for printing, whereas sRGB is more for displaying onscreen)
Your printer driver expects to receive RGB information, so if you sent it CMYK it would get converted back.

Hi Pisq
Now that was my initial thinking, as my simple approach was that sRGB was the most basic of all, and was there to work at the lowest level but on every thing down to the most basic. I was then thrown in all my reading by the Conde videos saying "use sRGB".

Sometimes lots of reading appears very counter productive.

So on the epsons is there a gain to be had from RGB, can they handle the gamut?

Think that that's a question for Paul, if he can knock up one of his little charts which shows your ICC compared to sRGB and Adobe RGB 1998.

i can't understand your question :redface::rolleyes:
do you asking what one is better for printing? sublimation?

in short:
AdobeRGB is better. it will give you more vibrancy and pop. where RGB will look more washed out.
AdobeRGB color space also offer MUCH larger colour gamut so this is another benefit to have your colour space set to adobe RGB.

Paul, that was my original thinking but I was thrown by Conde saying their icc are done in sRGB, and their videos set photoshop up for sRGB printing in sublimation.

So RGB1998 it is then.

Hi Janners,
For Sublimation the Sawgrass setting is for sRGB as , the colours reproduced are from generally from 4 colour's Cyan, Yellow, Magenta & Black known as CYMK, ie. Rico Printer's
To reproduce the full colour space of Adobe RGB you will have to wide format printers with 8 or more inks,
sRGB is the smaller centre of the Adobe RGB colour space and Adobe Lightroom uses Pro Adobe RGB which is a larger space again,
in Football term its a Kids Pitch . 6 a side and Full Match size , where the centre is the same but perimeter line , is small , medium and large,
So which colour space depends on , Image , the Inks , the Paper and the substrate, and the finish you are trying to achieve.
But as I understand it sRGB is the smallest standard colour space for working with images and printing,
Canon ship there Pro Camera's with sRGB as the default setting, You have to go in to the setting to upgrade to Adobe RGB.

Think of sRGB as the lowest common denominator - it will work OK across everything whether it's a screen, camera, or printer, and so it's set to be default on most things so it will "just work"
Now, you're a professional print company, and have a 7 colour wide format pro printer, with high quality inks, and custom colour ICCs to match it all together - if you want everything to "just work" and be OK then use sRGB, or if you want everything as good as it could be, than do a bit more work and make sure everything is working to an Adobe RGB 1998 colour space.

Ian, Andrea and Pisq
Thank you very much for that.

Andrea the bit about the 4 colours is so obvious .... now that you mention it! Didn't occur to me before.

Pisq. Helpful as always.

The little gamut charts you can make, which you sometimes post on here - can you make one which shows sRGB gamut, Adobe 1998 RGB, and Janners 7 colour printer ICC gamut? (your ICC software is better than mine!)
