What Is Coated Paper in English? Art Paper, C1S, C2S and Packaging Paper Terms

In packaging, 銅版紙 can be translated as coated paper or art paper, but the best English term depends on context. For box production, you should also specify whether the paper is C1S or C2S, the coating side, the board structure and the printing or lamination requirement.

What is 銅版紙 in English?

銅版紙 is commonly translated as coated paper or art paper. In packaging conversations, coated paper is usually the safer general term because it describes the coated surface used for better print clarity, smoother color and stronger image reproduction.

Art paper is also widely used in Asian sourcing contexts, but buyers should still clarify the exact specification, because suppliers may interpret it differently depending on region and paper grade.

Coated paper vs art paper

Coated paper describes a paper surface treated to improve smoothness, brightness and print performance. Art paper is a common commercial term, but it is less precise unless you also mention weight, coating side and application.

For paper boxes, the term alone is not enough. The supplier needs to know whether the material is used as outer wrapping paper, printed card, laminated sheet or part of a mounted board structure.

• Use coated paper when you need a broad technical term.
• Use art paper when your supplier commonly uses that sourcing vocabulary.
• Add C1S or C2S when coating side matters.
• Add gsm, lamination and box structure details for production.

What do C1S and C2S mean?

C1S means coated one side, while C2S means coated two sides. In packaging, C1S is often discussed when the print surface and the back side have different roles. C2S is used when both sides need a coated surface or when the printed piece is visible on two sides.

If the paper will be mounted to greyboard, folded into a box or laminated after printing, the coating side can affect glue adhesion, folding behavior and finishing results.

How to write a clear paper box specification

A clear paper box specification should include paper term, gsm or thickness, coating side, printing method, lamination, finishing and box structure. If you only write art paper, the supplier may still need several rounds of clarification.

For international sourcing, write both the common term and the production purpose. For example: C1S coated paper for outer printed wrap on rigid box, matte lamination after CMYK printing.

• Paper term: coated paper, art paper, C1S or C2S.
• Weight or thickness: gsm, board thickness or mounted structure.
• Use position: outer wrap, insert, sleeve, printed card or folding carton.
• Finish: matte lamination, gloss lamination, foil stamping, embossing.
• Printing requirement: CMYK, spot color, large solid color or fine text.

Common mistakes in English packaging terms

The most common mistake is translating a Chinese material name directly without describing how it will be used. Another mistake is treating coated paper, art paper, ivory board and greyboard as interchangeable. They may appear in the same packaging project, but they serve different structural and visual roles.

When in doubt, send photos, target structure and print reference together with the English term. Visual context reduces misunderstandings between design, sourcing and production teams.

Supplier inquiry checklist

Before requesting a quote, prepare the box type, product size, desired print look, paper term, finishing requirement and whether the material will be folded, mounted or used as a flat printed insert.

If you are not sure whether to use coated paper, art paper, C1S or C2S, describe the intended outcome instead: smooth printed surface, matte premium look, strong fold, outer wrap for rigid box or two-sided printed card.

Is art paper the same as coated paper?

They often overlap in sourcing conversations, but coated paper is more descriptive. Always clarify grade, coating side and application.

What does C1S mean in paper packaging?

C1S means coated one side. It matters when only one surface needs printing or when the back side is used for mounting or gluing.

What does C2S mean?

C2S means coated two sides. It is used when both sides need a coated surface or when both sides are visible.

Can coated paper be used for rigid boxes?

Yes, often as the printed outer wrap mounted onto greyboard, but the full structure and glue side must be specified.

How should I write 銅版紙 in an RFQ?

Write coated paper or art paper, then add C1S/C2S, gsm or thickness, finish, printing method and the box application.
