Does the weight of the paper stock effect durability and quality?
Yes, but only within the same type. For instance, let’s assume you chose 70 # vs. 50# offset text stock for a newsletter. The 70# stock would be more durable over time and result in less show through of the printed image from on side of a sheet to the other. However, let’s assume you choose 70# gloss text vs. 70# offset for your newsletter. The gloss stock would be more durable and result in greater ink holdout and glossier images than the uncoated offset stock.
