Automatic 7 Color Dry Offset Printing Machine for Cosmetic Toothpaste Ointment Tubes

Tube decoration has never been more demanding. Cosmetic, toothpaste and ointment brands expect vivid multi-color graphics, flawless registration and high output — all delivered on soft plastic tubes that must remain perfectly round and undamaged after printing. The Automatic Gravure 7 Color High Speed Dry Offset Printing Machine (Model LC-C7) from the LC brand meets that challenge head-on, combining seven-color dry offset printing, servo-driven precision and intelligent detection systems in a single, all-in-one production platform.

Rather than running tubes through several separate presses, the LC-C7 applies up to seven colors in a single pass. That means a complete tube decoration — from the base white and brand colors to fine details, gradients and small regulatory text — can be produced in one continuous cycle. For tube manufacturers, this all-in-one approach dramatically shortens lead times, reduces handling and eliminates the registration drift that plagues multi-machine workflows.

The dry offset process used here is particularly well suited to soft tubes, because it transfers ink from a plate to a blanket and then onto the curved tube surface without flooding the substrate. The result is a crisp, high-resolution image with excellent color density, even on the small diameters typical of skincare, toothpaste and pharmaceutical packaging.

Speed and stability go hand in hand on the LC-C7. Equipped with a Chinese indexer, the machine reaches a maximum printing speed of 250 pieces per minute, while its peak rated output climbs to 300 pieces per minute under optimal conditions. For factories running round-the-clock shifts, that throughput translates directly into lower unit costs and faster order fulfilment.

Key performance advantages include:

• Seven-color capability: ideal for full-color brand graphics on cosmetic and toothpaste tubes.
• High output: up to 300 pcs/min, with a stable 250 pcs/min on the indexer.
• Wide print area: a maximum printing length of 500 mm and printing height of 150 mm accommodate a broad range of tube sizes.
• Servo motor drive and control system: smooth, repeatable motion for consistent print quality and easy operation.
• No-cup and double-cup detection: the machine automatically detects missing or doubled tubes, preventing waste and protecting the printing blanket.

Continuous high-speed printing generates heat, and heat is the enemy of ink consistency. To keep the process stable, the LC-C7 features a dedicated water cooling system for the fountain roller and dancing roller. By controlling temperature at these critical points, the machine maintains uniform ink transfer hour after hour, protecting print quality even during long production runs.

In addition, a dancing roller automatic lubrication system keeps moving parts properly lubricated without manual intervention. This not only extends component life but also reduces downtime and maintenance labour — an important consideration for manufacturers who measure success in uptime.

Because it handles small-diameter soft tubes at high speed, the LC-C7 is the natural choice for a wide range of packaging producers, including:

Beyond raw speed, the dry offset platform offers a genuine quality advantage for tube decorators. The blanket-to-substrate transfer produces a smooth, closed ink film that resists cracking when the tube is squeezed — a common failure point for printed toothpaste and ointment packaging. Combined with the seven-color capability, makers can reproduce photographic-style gradients and fine typography that stay legible right down to the crimp. This is why many converters standardise on a single LC-C7 line to serve several product categories at once, switching jobs through a simple change of plate and settings rather than a complete re-tool.

• Cosmetic and skincare tubes for creams, lotions and gels
• Toothpaste tubes requiring bright, multi-color branding
• Pharmaceutical and ointment tubes with fine text and dosage information
• Industrial and personal-care tubes needing durable, high-definition decoration

Its all-in-one design makes it especially attractive to plants that want to consolidate several printing steps into one reliable line, improving both yield and floor-space efficiency.
