Better called a "Small Poster" or "Large Thick Paper Printing"

As this is a new product, I ordered a test print of a table/chart which was not yet quite complete and so will name updating in future. The shading came out well and I'm happy with how clear the printing was. However, I'm not sure "poster" is really the right word for this product. It's printed on paper that's only slightly thicker than normal but isn't glossy and it's not even very large, although the size was stated beforehand. At best, it could be called a "small poster", but to be honest, this product does not even fit my conceptualisation of that idea. Nonetheless, the quality of this product is sufficiently high that I would be willing to order it again, yet with the knowledge that what I'm getting is more of a large sheet of paper than what I would consider a poster.
