1. Sheetfed Offset Ink:

• Description: Oil-based inks used in sheet-fed offset printing presses. They adhere to a blanket cylinder, transferring the image to paper indirectly.
• Attributes: High color density, sharp detail, good press stability, excellent drying properties.
• Specifications: Pigment load: 10-25%, Solvent: Mineral oil, Vegetable oil, UV-curable resins.
• Applications: Brochures, magazines, catalogs, labels, high-quality printing.
• Industries: Printing, packaging, advertising.

2. Web Offset Ink:

• Description: Similar to sheetfed offset ink, but formulated for high-speed printing on continuous rolls of paper.
• Attributes: Fast drying, good heat resistance, excellent printability on various paper types.
• Specifications: Pigment load: 10-20%, Solvent: Mineral oil, Water-based, UV-curable resins.
• Applications: Newspapers, magazines, catalogs, high-volume commercial printing.
• Industries: Printing, publishing, packaging.

3. UV Ink:

• Description: Inks cured instantly by ultraviolet light, offering high gloss, scratch resistance, and chemical durability.
• Attributes: Fast curing, vibrant colors, suitable for various substrates (plastic, metal, glass).
• Specifications: Pigment load: 20-30%, Solvent: Reactive monomers, Photoinitiators.
• Applications: Labels, packaging, signs, displays, industrial printing.

4. Gravure and Flexo Ink:

• Description: Solvent-based inks used in gravure and flexographic printing, respectively. Gravure inks work with engraved cylinders, while flexo inks utilize raised printing plates.
• Attributes: High color consistency, excellent printability on non-absorbent substrates (plastic, metal).
• Specifications: Pigment load: 5-20%, Solvent: Alcohol, Mineral oil, Water-based.
• Applications: Flexible packaging, labels, plastic film, metal cans, textiles.
• Industries: Packaging, food & beverage, consumer goods, industrial products.

5. Metal Decorating Ink:

• Description: Specialized inks formulated for adhering to and decorating metal surfaces, often used in cans and containers.
• Attributes: High adhesion, heat resistance, food safety compliance, excellent printability on metal.
• Specifications: Pigment load: 15-25%, Solvent: UV-curable resins, Water-based.
• Applications: Metal cans, containers, closures, lids, decorative items.
• Industries: Packaging, food & beverage, cosmetics, pharmaceuticals.

Choosing the Right Ink:

The selection of the appropriate ink depends on several factors, including the printing process, substrate type, desired finish, and environmental considerations. Consult with a printing expert to ensure you choose the ink that delivers optimal results for your specific needs.
