I'm using good old Xara Xtreme 5 and I love it, don't see a reason to update (and I believe the new versions don't have a light interface if I remember correctly, otherwise I might upgrade)

How to BUILD UP an design in CMYK color profile? My printer requieres this, images build up in RGB become darker when later converted to CMYK.

I tried exporting in different ways, but important is (following the printer) that the design is made with CMYK profile and not exported/converted to RGB afterward.

Any tips?

Thanks!
