Most of the professional print materials you see in offices (including brochures, sales materials, posters etc.) are created by a method called offset printing. This produces very high-quality output on almost any desired medium (such as glossy paper, or card stock). However, it is usually only cost-effective when printing higher quantities (>500 units).
An alternative is laser color printing, which is much cheaper at lower volumes, but has drawbacks in terms of output quality, the ability to print right to the edge of the paper (full-bleed), reduced durability, and fewer meda options.
When developing any materials for print, It is important to be aware of the available output options and intended use so that the final product meets the desired standards of appearance, quality and cost-effectiveness.
