setting for printing in Fresco

How can I set the file to CMYK in Fresco？

Thanks for your input!

"If those RGB values are restricted to the gamut of your CMYK output, then they will print just fine."

How do you restrict the gamut in Fresco? 

I see no way to control it.

As I mentioned above, Fresco doesn't have that feature at the moment, but you can produce print-safe artwork by picking your colours from a palette that is already restricted to printable colours.

I provided instructions for producing it in the comments above.
It's a bit tricky but you only have to do it just once for each target cmyk colorspace. If you're going to work with the same print provider, you only have to do it once.

Otherwise it would be impossible to print digital photographs because cameras don't produce CMYK photos, for instance.

you do realise that many inkjets print with 10 colours?

So what's the point? You must support CMYK so many inkjet printers that use 10 colours can print your artwork in... what color model?
Before inkjet printers adding light variants of CMY and other tricks to expand gamut, PANTONE had the now defunct Hexachrome system that used CMYKOG (adding orange and green, to expand the printable gamut to those shades that they are impossible to print right with regular CMYK).
Both techniques were designed to produce prints with wider color gamuts BECAUSE regular CMYK can't deliver enough color latitude.
So if your comment was intended to support the idea that CMYK is needed because of those printers, it's actually the opposite: Those special color models are needed because CMYK is limited and you DON'T send CMYK to those printers (and if you do, it will be converted to a different color model anyway, so there your CMYK separations go).
If you meant something else, apologies. Please elaborate.

My apologies. I thought you were saying that you need to use CMYK. I was saying that you need to use RGB especially for large format or photographic printing. So I think we're on the same side, just that I misunderstood you and because of that, you misunderstood me.

Ah, ok. I see 🙂
What I meant in that specific line you quoted was that if it was impossible to print anything properly *without* CMYK, then digital photography would be unprintable. And clearly it is not.
I guess a lot of people mix up color models, color spaces and color gamuts as if they were the same thing and decide that if some color can't be printed is because of the color model and not the color latitude of the medium.
The reality is quite simple: There are many RGB shades that can't be printed basically because CMY inks are imperfect. Specifically if producing perfect pure and saturated cyan and magenta inks was easy and cheap, we wouldn't be having this conversation and we all would be sending RGB to print shops happily. CMYK only exists for technical reasons, and because of CMYK gamut is so severely restricted we have to deal with its caveats. But that doesn't mean that we NEED to edit in CMYK mode, that only means that we need to be careful and use mechanisms to avoid exceeding the destination media gamut.
Fesco could use those mechanisms better than a dedicated CMYK mode.
