COMPUTER STATIONERY OFFSET PRINTING MACHINE

The Computer Stationery Offset Printing Machine is a precision-engineered web offset press designed for producing continuous business forms and multi-part NCR stationery. Built for high-speed, long-run performance, it prints on continuous paper rolls to create invoices, challans, purchase orders, pay slips, and other pre-printed stationery used in dot-matrix and line printers.

Operating on the offset lithographic principle, it delivers sharp, uniform impressions with perfect registration across single or multi-colour jobs. The press is capable of printing on 2 to 6-ply carbonless forms, ensuring clear legibility on every layer.

Its integrated workflow allows multiple inline operations- including numbering, perforating, slitting, punching, and folding – enabling fully finished forms directly from the press. With rugged construction, accurate web handling, and continuous roll feeding, it ensures uninterrupted, high-quality production with minimal waste and downtime.

In short, it’s a complete solution for continuous stationery printing , combining speed, precision, and versatility to meet the demanding needs of modern form printing industries.

COMPUTER STATIONERY OFFSET PRINTING MACHINE Key Features

Available in configurations from two-colour to six-color printing units or as per requirements, this press handles everything from simple monochrome forms to full-color pre-printed continuous stationery. Each unit is precisely aligned to ensure accurate registration, even at high speeds.

The machine is specifically designed to print on 2 to 6-ply carbonless (NCR) paper. With perfect ink transfer and pressure calibration, it ensures legibility across all layers, making it ideal for invoices, bills, and official documents that require duplicate or triplicate copies.

Built for continuous operation, the press feeds paper from roll stock and prints uninterrupted. High-speed mechanical precision ensures tight registration and minimal waste, even on extended runs.

For jobs requiring sequential data (like invoice numbers or bill series), the machine can be equipped with inline numbering units — mechanical or high-speed inkjet — integrated into the workflow. This eliminates the need for post-print numbering, saving valuable time.

Equipped with both horizontal and vertical perforation tools, the machine allows forms to be easily separated or folded after printing. Inline slitting also enables multiple forms across the web width to be split cleanly and efficiently.

Depending on your workflow, the machine can be configured for:

Roll-to-Roll – For storing continuous forms
Roll-to-Sheet – For cut-sheet form applications
Roll-to-Zig-Zag (Fan-Folded) – For dot-matrix feeding systems

Constructed using robust side frames and precision-balanced cylinders, the machine ensures vibration-free operation even at high speeds. It is designed for 24/7 industrial use with minimal maintenance requirements.

With pneumatic plate clamping and tool-less ink and blanket adjustments, job setup and changeovers are fast and efficient. This reduces downtime, increases throughput, and is especially valuable for short-to-medium run lengths.

The advanced web handling system ensures consistent web tension and alignment across long runs. Optional servo-controlled registration units provide ultra-precise multi-color printing and form alignment.

Easy access to all printing units, ink trays, and rollers makes cleaning and maintenance quick. Intuitive controls allow even semi-skilled operators to run the machine with minimal training.

The machine layout can be tailored based on your requirements. From inline to stacked color units, optional attachments like margin punching, reel stands, sheeter units, or folding stations can be added to meet your specific production needs.
