What is the glossy material that is used many times on matte catalogue/brochure covers for text and logos?

Many catalogues and brochures (such as those for potential car buyers) have a matte surface, yet the letters, logos, or other small details may have a bit of a glossy surface. If you rub your hands over the matte part of the cover, they will glide, yet your fingers will slow when rubbing over the glossy letters or details. The glossy material isn't really raised, yet seems to be applied on top of the matte cover, so that you can feel there is a difference. I need to get a brochure professionally printed and I am wondering what this type of printing is called. Would anyone know about this? Thanks.
