The selection of coated paper can impact the appearance, touch, and functionality of your printed documents. There are two types of paper that are commonly used and available: C1S and C2S. The C1S and the C2S are very similar in name but are different in that the C1S is coated on one side and the C2S is coated on both sides.

When creating a brochure, catalog, packaging insert, magazine, or other print piece, this is an important consideration in determining what the top and bottom sides will look like. Knowing the distinction can help you pick the right paper for your printing needs and prevent you from paying for features you don't need.

C2S art paper is frequently a better option than the other papers listed above for projects where a uniform, printable surface is desired on both sides of the paper. 

What Is C1S Paper?

C1S = One side of the paper is coated; the other is not.

The coated side will create a smoother, more appealing surface for printing, making it an ideal choice for high-quality prints. The uncoated side is uncoated and can be as nice as paper for writing, stamping or printing if that kind of coating is not required.

C1S can therefore be used to provide a high quality coated finish on one side only. It can be used where, for example, the back has another function, such as labeling, packaging, cards, covers etc.

What is C2S Art paper?

C2S = Coated Two Sides. This paper is coated on both sides, giving a smooth and even surface for printing.

C2S art paper is especially beneficial when the reverse side of a printed product must display images, graphics, text or other visual information, which is comparable to the appearance of the front side.

A coated surface can give detailed commercial printing and a clean look. C2S paper is usually used for brochures, catalogs, magazines, promotion pieces, book covers and packaging products, depending on the application needed.

C2S can offer a more uniform look across the entire material for businesses that create materials that are meant to be displayed on both sides.

C1S vs C2S: What Is the Difference?

There is only a difference in the number of sides coated. This difference, however, does impact how the paper can be used.

So, it's not so much which paper is better overall as much as what the finished product needs.

When Should You Choose C1S?

The use of C1S may be appropriate when coating is primarily required on one side of the surface.

For instance, if the front of a printed item features a picture, graphics, and/or logos, and the back is used for a practical purpose, it may not be worth coating both sides.

It can also be helpful when the back has to be written on or when a different design is to be used on the back than on the front.

In such cases, C1S will be able to perform the design requirements without coating both sides. 

When Is C2S Art Paper the Better Choice?

When prints require a smooth and consistent look on both sides, C2S art paper comes into play.

Consider a catalog in which customers flip through the pages and find printed information on all sides. This is true of brochures, magazines, promotional literature, and other items that involve two sides of the document being involved in the imagery.

C2S is also recommended for designs that feature photographs, illustrations, product information, or detailed graphics on both sides of the design. It is coated on both sides to offer a stable base for the printed design overall.

Manufacturers, publishers, printers, or packaging companies will typically not have just a paper specification to consider but also the final product.

How to Choose Between C1S and C2S

The first step is to observe the intended use of the paper.

1. Check whether both sides need printing.

For single-side printing, C1S can be used. When the two sides require almost the same final look, C2S is generally the better choice.

2. Consider the design.

Consistent surface and a design with photographs, detailed graphics, and strong visual elements on both sides can work well together.

3. Consider the back side.

C1S might be more suitable when the back must be uncoated for writing, stamping, or other applications.

4. Match the paper to the finished product.

Think about what kind of book you are creating, such as a catalog, brochure, magazine, packaging, cover, or other print product. Make sure that the paper you select is appropriate for the purpose.

5. Confirm the required specifications.

If ordering, please verify with your paper supplier on paper weight, surface characteristics, print process, sheet/roll format, and other technical requirements.

Why C2S Is Commonly Used for High-Quality Printing

Consistency is one factor of why businesses opt for C2S paper. Both sides are printed, creating a uniform surface for the print media.

It is particularly useful for products that are read or used by readers or customers frequently on both sides. A single set of paper characteristics can be used for the entire sheet, rather than for two different papers.

The final outcome still relies on the printing technology used, ink, finishing, paper and production conditions. The right type of paper is thus one aspect of creating the desired effect.

Choosing the Right C2S Paper Supplier

If it has been identified that C2S is suitable, then the next step is the selection of suppliers. Don't be satisfied with the name of the product; ask the supplier whether their product is available with the specifications you require for your application.

Some considerations might be paper grades and weights available, sheet or roll size, quality uniformity, the amount that can be manufactured, requirements for customization, and experience with the intended use.

A supplier should also be able to give buyers clear information about the product so that the buyers can decide whether the paper is suitable before they enter the larger-scale production.

TONLI is tailored for businesses that specifically need to use C2S products; TONLI art paper is a product with a coated surface on both sides. To make sure it suits your project, it's best to compare the different specifications and measure them against your printing needs.

Conclusion 

The important difference between C1S and C2S paper is that the C1S paper has one coated side, whereas the C2S paper has two. It is determined primarily by the intended application of the printed product and how it will be printed.

Use C1S for two different surfaces, one coated and one uncoated. Select art paper with a coated surface for both sides for art-quality printing when both sides need a smooth, even coating.

C2S can deliver the uniformity in the project that is necessary when print is two-sided coated. The important thing to remember is to select the paper that best fits the paper specification and not only the name of the paper.
