What is the difference between coated and uncoated paper?

The main difference between coated and uncoated paper is that coated paper is produced with a layer of clay during the manufacturing process. Coated paper absorbs less ink, which causes a printed image to sit on top of the paper; versus an uncoated stock, which is more porous so the image is absorbed into the paper itself. Images printed on a coated stock tend to look crisper and more vibrant, whereas on uncoated stock images look softer and more natural.

Think of uncoated paper as traditional copy paper and coated paper as a shiny tri-fold brochure or inside a nice magazine. Both types of paper are available in a wide variety of thickness - from very thin copy paper to thicker postcards and business cards - as well as a variety of finishes and textures. One stock is not any better than the other though - it is more about personal preference and the desired outcome of the job itself.

Some considerations when choosing the right stock for your project are whether you will add another finish, or whether the paper will need to be written on.

When adding a specialty finish, such as UV Coating, it is important to keep in mind that only coated stocks can accept a liquid coating because the clay allows the new coating to sit on the top surface without being absorbed during the drying/curing process.

If you will need the ability to write on the printed product with a pen or pencil, for example an application, appointment card, notepad, letterhead, or envelope, then uncoated in the clear choice. Felt pens, like Sharpies, work easily on both stocks, but aren’t always the desired writing tool. How often do you write a thank you letter to a client in Sharpie?
