I had never used the Canon Luster before but it was cheaper to buy this than the Epson 11x17 glossy that I'd planned on getting,

In fact, this Canon Luster is actually manufactured by Hahnemuehle

I bought two of these (50 sheets, Canon Luster, 13"x19") on sale just before Christmas (a present to myself, haha) for $25 a box with free shipping

If you print large format images from quality photos, I think you will be pleased with the Canon Luster paper.

and I almost always prefer the results of the Canon Luster Photo Paper the best

Compared with using fine art paper and canon Luster Photo Paper, I will go with the luster photo paper

I print on the Canon Luster paper using a Canon Pixma Pro 100 printer using a Canon Supplied printer profile

So my recommendations are to buy whichever of Canon Luster or Semi Gloss that is least expensive at the time

Good as always.

Overall, the detail, resolution, and color accuracy of this Pro-100 are superb, worthy of gallery displays and at least as good as, or better than, prints that you order from a drug store or retail department store.
