RK Pad Printed Uncoated Paper, Color : White, Transparent

Pad printing on uncoated paper involves using a printing technique that transfers ink onto the paper surface using a silicone pad. This process is widely used for printing on irregularly shaped or difficult-to-print objects, and in this case, uncoated paper is the substrate being printed on.

Here is a typical specification and description for pad printed uncoated paper:

• Type of Paper: Uncoated paper refers to a paper that does not have any glossy or smooth coating. It is typically more absorbent and has a matte or natural finish.
• Surface Texture: Rough, natural, and untreated. This texture can absorb ink well, but it might lead to slight bleeding of ink or reduced sharpness compared to coated surfaces.
• Thickness: Uncoated paper can vary in thickness, but it generally ranges from 70 gsm to 300 gsm depending on the printing and product requirements.
• Finish: Matte finish (uncoated). This provides a more natural, organic look and feel compared to glossy finishes.

• Pad Printing Description: A specialized printing technique in which ink is transferred from a printing plate to the substrate (paper) via a silicone pad. This process is ideal for printing on irregular surfaces, and it can handle small, detailed designs.
• Ink Type: Typically, solvent-based or UV curable inks are used in pad printing. For uncoated paper, inks need to be specifically formulated to adhere properly to absorbent surfaces and prevent smudging or fading.

• Absorbency: Because uncoated paper absorbs ink more than coated paper, the ink used must be optimized for this absorption, ensuring rich color saturation without excessive bleeding.
• Drying Time: The drying time on uncoated paper will be relatively quicker because the paper absorbs ink faster. However, depending on the ink type, additional curing (such as UV light) may be required for faster drying.
• Color Quality: Due to the absorbent nature of uncoated paper, colors may appear slightly muted or softer compared to their appearance on coated surfaces.

• Products: Ideal for products like stationery, envelopes, packaging (such as gift boxes or paper bags), labels, and promotional materials that require an organic and natural look.
• Usage: Commonly used for small-run printing jobs, where high-quality and detailed printing on irregularly shaped or rough-textured surfaces is necessary.

• Precision: Allows for fine details, such as logos, text, and designs to be transferred accurately.
• Versatility: Suitable for printing on non-flat surfaces or areas with a texture.
• Cost-Effective for Small Runs: Because pad printing does not require plates as expensive as those in offset printing, it's often used for small or medium runs.

• Ink Bleeding: Because of the absorbent nature of uncoated paper, ink can spread out beyond the intended print area, leading to reduced sharpness.
• Limited Durability: The print quality may not be as long-lasting as printing on coated paper, as uncoated paper can wear down more quickly.

• Resolution: Generally, pad printing allows for high-resolution prints, but the resolution may be affected by the absorbency of the paper. The detail may be slightly softer than on coated surfaces.
• Small text/Designs: Can be successfully printed, but the ink spread can cause slight fuzziness in very small fonts or intricate designs.

• Sustainability: Uncoated paper tends to be more environmentally friendly, as it usually contains fewer chemicals and is biodegradable.

Pad printing on uncoated paper provides a unique solution for printing on natural, textured materials, offering a more organic look and feel compared to coated paper. However, special attention must be paid to the type of ink used to ensure good adhesion and minimal bleeding.
