When choosing the most suitable paper to print your project on, you will often have to choose whether you want to use what is referred to as uncoated paper or coated paper. Not only does each type of paper produce its own unique finishes but they are also different in terms of ink absorption.
Uncoated stocks will typically absorb the ink more, producing a more soft and muted look. This type of choice is great for those looking for an earthier feel to their printed piece. One of the cons of using uncoated paper is that you lose some of the sharpness in the detail.
Coated stocks are uncoated papers with an added coating such as matte, semi-gloss, matte and silk matte laminate. Coated paper is great for making details pop and can be more durable and mark less when handled.
You will notice a difference in thickness of coated paper and uncoated papers that are the same weight. During the coating process, the paper will be repeatedly smoother which will compress the fibers in the paper together, making them significantly denser. This can make coated paper feel thinner even when it is the same weight as uncoated stock.
