I have presentation paper thats 28lb (4.9 mil) in matte that I use to print digi papers but I'm pretty sure it comes in glossy as well. The brochure paper I have is 9 mil, but it is thicker than the presentation paper. The nice thing about brochure paper is you can print on both sides. The presentation paper I have is only coated on one side, so you can only print on the coated side. You may be able to find a lighter weight brochure paper in glossy or semi-gloss. I have the Epson brand presentation paper, so you should be able to find it in any office supply store.
So, long story short
, check your office supply store for presentation paper.
