ROTOGRAVURE PRINTING MACHINE

ROTOGRAVURE PRINTING MACHINE

1. What is the work of this machine?

A rotogravure printing machine is a high-speed, precision printing press primarily used for large-volume printing jobs on flexible materials like plastic films, paper, paperboard, and foil. It is commonly used for packaging (food, pharmaceuticals, labels), magazines, and decorative laminates.

1. Flexible Packaging (Food, Pharma, Consumer Goods).
2. Labels & Stickers.
3. Newspapers & Magazines.
4. Decorative Laminates & Wallpapers.
5. Prints high-quality, consistent images using an engraved cylinder.
6. Suitable for long print runs due to its durability and speed.
7. Uses solvent-based or water-based inks for vibrant colors.
8. Can print on both sides (if configured as a CI press – Central Impression or Stack type).

Key Components of a Rotogravure Printing Machine:

Engraved Cylinder:

1. 1. The core of the process, typically made of steel or copper, with tiny cells (engraved pits) that hold ink.
   2. Engraving methods include electromechanical, laser, or chemical etching.

Inking System:

1. 1. 1. A trough supplies ink to the cylinder.
      2. A doctor blade removes excess ink, leaving ink only in the engraved cells.

Impression Roller: Presses the substrate (e.g., film, paper) against the engraved cylinder to transfer the ink.

Drying System: Hot air or UV drying ensures fast ink setting for high-speed printing.

Substrate Feeding & Rewinding: Unwinds the material (e.g., plastic film, paper) before printing and rewinds it after drying.

Advantages of Rotogravure Printing:

✔ High-quality prints with fine details and rich colors.
✔ Excellent for long runs (millions of impressions) without quality loss.
✔ Works on various materials (flexible packaging, labels, magazines, etc.).
✔ Consistent output due to durable cylinders.

Disadvantages:

✖ High setup cost (cylinder engraving is expensive).
✖ Not economical for short runs.
✖ Longer setup time compared to flexography or digital printing.

Applications:

1. Packaging (food, pharma, flexible plastics)
2. Publishing (magazines, catalogs)
3. Decorative printing (wallpaper, laminates)
4. Security printing (banknotes, certificates)

2. How many workers are needed to operate it?

1–2 skilled operators (for setup, ink management, and monitoring).

1–2 assistants (for material loading/unloading and quality checks).

Maintenance technician (periodic checks).

Total: 3–5 workers per shift depending on automation level.

3. What is the production capacity?

Speed: ~5–60 meters/minute (depends on material & design).

Daily Output: ~7,200–80,000 sqm (24-hour operation).

Monthly Capacity: ~0.2–2 million sqm (continuous production).

4. What is the electricity cost?

Power Consumption: ~50–62 kW (varies with size and automation).

Estimated Cost:

1. Per Hour: ~$5–10 (depending on local electricity rates).
2. Per Month: ~$150–300 (running 12 hours/day).

5. How much space is needed to install this machine?

Small Machines: ~9000mm (L) × 2200mm (W) × 2500mm (H).

Large CI Presses: ~9000mm (L) × 2700m (W) × 2500m (H).

Requires additional space for drying, unwinding/rewinding, and storage.
