Understanding Paper Types: C2S Paper vs C1S Paper

Coated papers are widely used in the printing industry due to their enhanced print quality and durability. They come in different varieties, including C2S (Coated Two Side) and C1S (Coated One Side) papers. In this article, we will delve into the differences between C2S and C1S papers, and help you understand which one is best suited for your print projects.

What’s Coated Two Side Paper


C2S paper, as the name suggests, is coated on both sides. This means that both sides of the paper have a smooth and glossy finish. The coating is typically made of clay and other minerals, which enhances the paper’s printability and provides a high-quality appearance. The smooth surface of C2S paper allows for sharp and vibrant printing, making it ideal for projects that require vivid colors and images.

C2S paper is commonly used for brochures, catalogs, magazines, postcards, and other promotional materials. Its glossy finish gives a professional look and enhances the visual appeal of the printed content. The coating on both sides of the paper also provides excellent ink holdout, preventing the ink from being absorbed into the paper fibers and resulting in vibrant and crisp printouts.

What’s Coated One Side Paper


On the other hand, C1S paper is coated on only one side, leaving the other side uncoated. The coated side has a glossy finish, while the uncoated side retains the natural texture of the paper. This type of paper is commonly used when a glossy appearance is desired on one side, while the other side needs to be writable or have a matte finish.

C1S paper is often used for projects such as book covers, board books, greeting cards, packaging inserts, and labels. The coated side of the paper enhances the visual appeal, making the printed content stand out.

C2S vs C1S Paper: What’s the Difference

The main difference between C2S and C1S papers lies in the coating. C2S paper has a glossy coating on both sides, while C1S paper has a coating on only one side. This difference in coating affects the overall appearance, printability, and application of the papers.

C2S paper is known for its high gloss and vibrant colors. The glossy coating on both sides of the paper allows for sharper and more detailed printing, making it ideal for projects that require rich, high-quality images and text. C1S paper, on the other hand, allows for a glossy appearance on one side and a matte or writable surface on the other, making it more versatile for projects that require different finishes on each side.

What Types of Projects Should Use C2S Paper

C2S paper is best suited for projects that demand high-quality and visually striking printouts. Its glossy finish and excellent ink holdout make it perfect for marketing materials, such as brochures, catalogs, and postcards. The vibrant colors and sharp images achieved on C2S paper help capture the attention of the intended audience.

Additionally, the books like magazines, photo books and coffee table books, etc can benefit from the use of C2S paper. The glossy finish enhances the visual appeal and gives a professional look to the content. The durability of C2S paper also makes it suitable for projects that require frequent handling, such as menus and instruction manuals.

What Types of Projects Should Use C1S Paper

C1S paper is a versatile option for projects that require different finishes on each side. It is commonly used for book covers, board books, where a glossy appearance on the outside creates an eye-catching design. While the uncoated side on the inside allows for wrapping or non-reflective look.

Greeting cards and packaging inserts can also benefit from the use of C1S paper. The glossy side adds a touch of elegance to the design, while the uncoated side provides a surface that can be written on or allows for a more muted aesthetic.

What is Thicker: C2S vs C1S Gloss Cover

When it comes to thickness, both C2S and C1S papers are available in various weights. However, if we compare the gloss cover options of both types, C2S paper is generally considered thicker than C1S paper. The thickness of the paper is measured in points, with a higher point value indicating a thicker paper.

The thickness or weight of the paper you choose depends on the specific requirements of your print project. Thicker paper is generally more durable and provides a more substantial feel. It is often preferred for projects like business cards, postcards, and invitations, where a premium look and feel are desired.

C2S vs C1S Paper: How to Choose for My Print Project

Choosing between C2S and C1S paper depends on the specific requirements of your print project. If you need high-quality, vibrant images and a glossy finish on both sides, C2S paper is the ideal choice. It is perfect for projects that demand attention-grabbing visuals, such as magazine covers and marketing materials.

On the other hand, if you require a balance between a glossy and matte appearance or need to print on only one side, C1S paper is the better option. Its versatility and smooth matte surface make it suitable for a wide range of projects, including brochures, book covers, board books, and business cards.

When selecting the thickness of the paper, consider the durability and feel you desire for your project. If you need a sturdier paper, C2S paper with its thicker profile is the way to go. However, if a thinner paper is sufficient for your needs, C1S paper with a gloss cover will work just fine.


Understanding the differences between C2S and C1S papers is crucial in selecting the right option for your print projects. Consider the type of project, desired appearance, and required thickness to make an informed decision. By choosing the appropriate coated paper, you can enhance the visual impact and overall quality of your printed materials.
