RK Plain Uncoated Paper Roll And Sheet, Color : Black, White

Uncoated paper is made from wood pulp and is often used for printing and writing. Unlike coated paper, which has a glossy or matte surface finish, uncoated paper has a more natural, textured feel and absorbs ink better. It is available in both rolls and sheets, making it suitable for different printing and publishing needs.

1. Material Composition:

   • Made from wood pulp (either recycled or virgin fiber).
   • The paper may also contain small amounts of fillers like calcium carbonate or clay to enhance opacity and smoothness.

2. Grammage (Weight):

   • The weight is typically measured in grams per square meter (gsm).
   • Common weight ranges: 70 gsm to 200 gsm.
   • For example: 80 gsm for office paper, 120 gsm for brochures, 150 gsm for posters.

3. Finish:

   • Texture: The paper can have a rough, smooth, or vellum texture. The texture of uncoated paper is often noticeable, offering a more natural feel than coated papers.
   • Opacity: Uncoated papers typically have moderate opacity, which means there might be some see-through when printed on both sides, depending on the weight of the paper.

4. Brightness:

   • Brightness is usually between 80 to 90 on the TAPPI scale (the standard for measuring paper brightness).
   • It offers a natural, soft white color but not the intense whiteness of coated papers.

5. Surface Quality:

   • Uncoated smooth: Ideal for high-quality text printing and publications.
   • Uncoated rough: Suitable for artistic applications like high-end invitations, or fine art prints.

6. Durability and Strength:

   • Tensile strength: The paper tends to be durable, with good tensile strength.
   • Resistant to tearing but can be more prone to wrinkles compared to coated paper.

7. Printability:

   • Ink absorption is higher, which means prints may appear softer than on coated papers.
   • It is ideal for offset printing, digital printing, letterpress, and some forms of flexography.
   • Absorbs ink easily and is compatible with most standard ink types.

8. Sizes:

   • Sheets: Typically available in standard sizes such as:
     • A4 (210 x 297 mm)
     • A3 (297 x 420 mm)
     • Letter (8.5 x 11 inches)
     • Legal (8.5 x 14 inches)
     • Custom sizes as per the customer requirement.
   • Rolls: Available in various widths and lengths, depending on the printer’s needs.
     • Common widths: 24, 36, 42, 48 inches.
     • Length: Can range from 100 meters to several kilometers, depending on the manufacturer and application.

9. Environmental Impact:

   • Uncoated paper is often seen as more environmentally friendly because it can be produced with a higher percentage of recycled content and is biodegradable.
   • Many uncoated papers are FSC certified, meaning they are sourced from sustainably managed forests.

• Office Use: For letterheads, presentations, memos, and reports.
• Printing & Publishing: Books, magazines, brochures, and business cards.
• Packaging: Shopping bags, gift packaging, and labels.
• Stationery: Invitations, notepads, and envelopes.
• Marketing Materials: Flyers, posters, and catalogs.

• Natural look and feel: It provides a tactile, natural appearance that some businesses and designers prefer.
• Better ink absorption: Ideal for high-quality text prints.
• Versatility: Suitable for a wide range of applications, including art, text, and general printing.

• Ink Smudging: Because of the higher ink absorption rate, there's a risk of ink smudging, particularly in fast-drying methods.
• Less Vibrancy: Colors printed on uncoated paper tend to be less vibrant than on coated paper.
