Argb...or just rgb?

I'm using a 5D and have the camera set to argb,my dpp settings is set to argb.
I'm using a epson 1800 printer.
My question is :should I be setting the camera and dpp to just rgb?
Am I gaining anything setting the camera and dpp to argb?

My prints are coming out with an exact match to my calibrated monitor

Any advice would be appreciated

Thanks
Mike

My understanding of the two is that the Adobe has a wider gamut of colors. This is better suited for printing.

sRGB, while also good enough for printing, doesn't have such a wide range of tones/colors but may be better for viewing on computer as more computers/programs/web​browsers/etc. will recognize the sRGB colorspace whereas with the adobergb it will discard it so you may not be too sure how it will look on other peoples' computers.

I'm sure someone will correct me if I'm wrong

In this case, since the OP cited an Epson 1800, AdobeRGB would be a better choice. In fact, with glossy paper and the right profile the 1800 can print a gamut wider than AdobeRGB, so if the image contains very saturated colors it might be worthwhile exporting to WideGamutRGB from DPP or ProPhotoRGB from Adobe products.

"Just RGB" doesn't make sense, you probably mean Adobe RGB or sRgb. Adobe RGB is a better choice, for the reasons Elie pointed out.

Thanks guys for your replies.
Yes,I did mean srgb..sorry bout that.,which brings me to my next question :

The prints I'm getting are coming out perfectly,using,Museo'​s silver rag paper,and the icc profile from crane's.
In your expert opinions,would I be better off,getting a custom profile made,for this paper/printer combination?
Will I see a dramatic difference in the prints?

If you're getting a good match now & good looking prints, frankly, I wouldn't bother.

About the output color space: Why not give it a try. As Elie says, you might even want to try WideGamut RGB.

Rene,thanks for your reply.
What I'm actually trying to do is yo standardize my work flow,and make it as simple as possible
If you thing the wide gamut rgb might help ,I'll give it a try.
Another issue is the paper...I must have tried a dozen papers,so,far the Museo silver rag, looks the best as well as Epson luster.
Woud you suggest I get a custom profile done for these papers,will I see much of a difference?

Thanks again
Mike

I don't know whether you'll see much difference, as I don't know what you are seeing now... But if you get a good match, and a good print, I'd not think its needed. (It might be fun to experiment & post the results here though! :mrgreen

Problem with using a wide gamut working space on a smaller gamut monitor is that you're not seeing what you're doing. So you might have colors in your image that show up fine in print, but clip onscreen. Trust the clipping warning & the histogram in that case. But it won't get any easier or more intuitive.
