Professional lab print equivalent of Epson Premium Semi Gloss?

[steve_bright1]

I need to get some lab prints made from my digital images. I have

been using CostCo for a while and have been very pleased with the

results on their glossy Fuji Crystal Archive paper. However, my new

client wants a finish which is very similar to Epson Premium Semi

Gloss, which is a kind of lustre finish - if you hold it at an angle

to the light it looks as if there's millions of little sparkles

instead of a mirror finish.

 

CostCo in the UK only do the gloss finish, so could anyone advise me

of either a) a lab in the UK which does prints with that finish, or

b) what type of lab printing paper has that finish, so I then know

precisely what to ask for.

 

Many thanks for your help.

I don't know the exact details, but I know there's a version of Crystal Archive kinda like that, though it may actually be closer to Epson Premium Lustre (coarser texturing to the gloss for fewer but bigger "sparkles").
