I recently used Fotojet Pro Satin by the Swiss firm Folex Imaging, to print about 100 prints of my nephew's colourful wedding in S.E.Asia.
The detail and colour depth on my canon BJC8200 exceeded my expectations, and every one that viewed them remarked on the quality.
It's a heavyweight paper, 270gsm, and cost £18.80 for 50 A4 sheets from choice stationery, and it's recommended for all the well-known makes inc HP.
Have a look at their website. Hope this helps, Toxin
