How can you tell if a JPG is RGB or CMYK?

FelinePrincess

Hi,

I hope someone can help me, I have tried google and can't seem to find a simple way of doing this.

So, can anyone tell how I can find out if a jpg image is in RGB or CMYK format?

Thanks in advance!

Crikey, why would you need to know something like that?

Irfanview does it. Open the file, image menu, information.

I need to get something printed and I'm told it need to be in CMYK but not sure what format my images are in.

All your photos will be RGB, off-set printing is all CMYK (standard for leaflets and most printed literature), so you'll need to convert, you lose a lot of colour information when moving to CMYK as there are many shades/tones that can't be reproduced, otherwise know as "out of gamut". Higher quality off-set printing can add a couple of additional colours to improve the colour range.

Good photographic printers and album companies don't print using CMYK but instead use a more sophisticated colour reproduction similar to that of the older photo developing to get the full colours in photos.

Try using Paint.Net www.getpaint.net - much more sophisticated and free, rather than IrfanView.

Irfanview's free. It's a media file viewer. paint.net is an image editing application. completely different purposes, both free.

You can donate to both, of course.

Not all the images will be RGB. Several file formats allow the colour profile to be CMYK.

What was the point in your (mostly erroneous) post?
