I am not familiar with the Canon Glacier and have not tried the previous lasal luster from Moab so I cant comment on wether its the same paper. I doubt it though as my source (my paper supplier) tells me its actually a paper that was OEM'd by an Australian (Giclee Media) and taken by Moab and re-branded for the American market (which would not surprise me). I am told it sold and continues to sell in Australia as Lasal Professional Alpine Pearl. See Here
http://gicleemedia.com.au/gms43/Moab-Lasal-Professional-Alpine-Pearl-Photo-Paper-300/ This paper is made in the US for the Australian market.
I should add that this comes straight from the horses mouth - as in I buy my paper from GicleeMedia and was told this today when picking up the paper.
The paper industry is so incestuous with manufacturers taking each others papers and rebranding that it can be very difficult to get to the bottom of what paper is the same as the next under a different name. Looking at the Alpine Pearl it meets all the specs of the Moab Lasal Exhibition; combined with my source pretty much confirms for me its the same paper.The fact they (GicleeMedia) have added the word Moab to their description of the Alpine Pearl speaks volumes to different naming for different countries.
Regardless of all that nonsense -
I have now made a couple of test prints on the new Lasal Exhibition Luster or Alpine Pearl
(referred to hereafter as LEL) and I quite like it. I wouldn't say its game changing; but its the best RC paper I have tried (I should add I have not tried a huge number). You get everything you would expect from a high quality RC paper - great Dmax, very sharp, strong color and I do like the stipple and relfectivity characteristics. Comparing against the ilford smooth pearl again I prefer the heavier weight and slightly less plasticky feel of the LEL. The LEL also appears to have the better Dmax and deeper more saturated color; but I have not a spectro to hand to confirm what my eyes tell me.
I cant comment more than this at present as I dont have any more of it to continue to print on to make meaningful comparisons against other papers. I will probably order a box or two next week and make a custom profile and do more extensive testing based on the first results I have seen. Its good enough to warrant more effort and investigation for me.
Edit - Forgot to add -Im printing with a Canon IPF 6350 at present.
Also - this LEL paper appears very scuff and scratch resistant. It passes the fingernail test without a problem. All the Bayta papers I have tried most definitely do not.
