South Korea–made paper cup side paper offset printing machine is a machine used for low‐volume and custom‐printed production of paper cups. These machines enable high‐quality printing on the exterior surfaces of cups. Also called “fan” or “blank.” The terms fan or blank refer to the cut‐paper shapes used in the paper cup production process. This machine is used to apply advertisements, promotional logos, and various graphics onto the side paper of paper cups.
Features of the Paper Cup Side Paper Offset Printing Machine
Offset Printing Technology: Offset printing works by transferring ink from printing plates onto a rubber blanket roller, which then presses onto pre‐cut cup side papers. This technology enhances print quality and delivers vibrant colors.
Full‐Color Printing: The offset printer uses the CMYK (Cyan, Magenta, Yellow, Black) color model to produce multicolor prints. This ensures that designs meet brands’ specific color requirements.
Print Area: Side papers for paper cups start out flat before being formed into a cylindrical shape. These machines print on flat paper strips, which are then converted into cups. The print is applied to the side surface, since that area becomes the cup’s exterior once formed.
Printing Speed and Efficiency: Capable of high‐speed printing, this machine can print 80–100 pieces per minute, achieving minimal waste. It uses side papers previously cut on a paper cup punching cutting machine.
High Print Quality: Offset printing can reproduce fine details, small text, and complex graphics crisply—ensuring professional‐grade branding and designs.
Color Accuracy: Offset printing provides excellent color consistency per run so each copy matches exactly.
Ink and Drying Systems: Water‐based inks are commonly used for eco-friendly applications. These inks reduce VOC (Volatile Organic Compounds) emissions and minimize environmental impact.
Drying: After printing, the ink is dried using UV curing or air drying systems. These drying units allow the printed paper to be used immediately.
Printing Plates: Offset plates are customized for each design. Each color gets its own plate, and ink is transferred to the cup side paper during printing. Plates are prepared to ensure consistent, high‐quality output every time.
Advantages of the Paper Cup Offset Printing Machine
High Print Quality: Offset printing delivers high resolution and color accuracy, ensuring brand designs appear crisp and vibrant.
Fast Production Capacity: The ability to print at high speed is a major advantage for large‐scale cup production. These machines operate with high efficiency, speeding up the workflow.
Flexibility & Customization: Offset presses can handle multicolor and complex graphics, offering custom brand colors or special effects easily.
Eco-Friendly: Using water‐based inks and environmentally friendly processes lets you produce without harming the environment.
Cost-Effective for Large Runs: Offset becomes more economical at high volumes, lowering cost per print. High throughput reduces overall costs over time.
