I'd appreciate it if someone could give me a couple of pointers on this.
(PS7, Windows XP)

As my business is supplying RGB files to agencies I know nothing of CMYK 
which has been OK up till about 6 hours ago. However, today I have been asked 
to supply an art gallery with prints.

I have found a printer who does giclee prints. (I remember a whole load of 
prodig posts on giclee a while ago but unfortunately it was before the 
archive was set up) 

I only seem to get to speak to someone (the owner!) who doesn't seem to be 
able to tell me much except "provide CMYK files". 
I have "converted" the RGB's to CMYK in PS7. They lose a lot of the vivid 
colours straight off. Pouring over Martin Evening's book I have learned about 
Relative Colorimetric and Perceptual, with and without black point 
compensation. Generally the images look better with RC + black point.

So now to the Colour Settings. Under Colour Spaces > CMYK I don't know if I 
should tick Euroscale uncoated v2 or coated V2 (or any of the others)?  
I am going to have them do three small A5 tests on Somerset Bright White 
Watercolour, Cotton Canvas and Matt Paper.

I asked him what ppi I should supply. He said "it depends". So I volunteered 
helpfully 300? He said that's a good average! So I presume I should go for 
that?

I haven't had any prints done before so don't know how much sharpening should 
be done. I'll be doing 21inch x 7inch landscape panoramics. Martin Evening's 
book says that often it's not what it looks like on the screen but experience 
that counts on this. Er, my experience is nil, I know "it depends" but I'd 
sure like a ball park figure to start me off. I have read USM 200/ 1.5/ 0 on 
smaller images for the web but what about large prints?

I realise that converting to CMYK is not simply a matter of ticking these 
various menu pull downs but it's all I have time for right now, so any advice 
anyone could put forward; to at least give these tests a fighting chance 
would be very useful indeed.
