TTN Series 100 Automatic Pad Printing Machines

Pad printing is a precise and economical marking technique, particularly suited for small objects, complex shapes, and irregular surfaces.

• High precision: ideal for logos, fine texts, and complex details.
• Marking on complex shapes: allows printing on curved, domed, hollow, or irregular surfaces.
• Wide material compatibility: plastic, metal, glass, wood, ceramic, etc.
• Economical for series production: low marking cost for medium and large productions.
• Excellent print quality: sharp rendering with good marking consistency.
• Suitable for small objects: perfect for pens, caps, industrial parts, promotional items, and technical components.

Pad printing is very versatile, but it does have some limitations:

• Limited maximum surface area: suitable for small to medium-sized objects, the marking diameter is limited by the ink cup size.
• Restricted number of colors: limited by the number of ink cups installed (e.g., 2 ink cups = 2 colors). To go beyond this, successive re-printing is possible, provided ultra-precise repositioning of the parts.
• Irregular or textured substrates: overly pronounced reliefs can hinder ink transfer.
• Reduced speed for complex series: objects requiring multiple colors or steps can slow down production.
• Limited finishes: less suitable for gradients or complex photo prints compared to UV or digital printing.

Volume logic (the cliché/plate):

• This process requires the manufacturing of an intaglio plate engraved by insolation.
• Economically, this step directs pad printing towards medium and large series.

Amortization of fixed costs:

• The larger the series, the lower the unit cost.
  • Example: a 15 € plate costs:
    • 1.50 € / piece for a series of 10 objects
    • 0.15 € / piece for a series of 100 objects

Pad printing follows a precise process allowing a visual to be reproduced on many types of objects:

• Graphic Preparation: creation of the visual using vector drawing software or DTP (Illustrator, InDesign…), with color separation (one color = one plate).

• Plate Manufacturing:r

  • Digital Technology: direct and precise engraving of the plate using a fiber or CO₂ laser.

  • Analog Technology: printing a transparent film, UV exposure of the photopolymer plate through this film, development, drying, and post-exposure for stabilization.

• Setup and Inking: preparation of ink mixtures, filling of ink cups, and mounting of plates on the machine heads.

r

• Inking and Image Pickup: the ink is deposited into the engraved areas of the plate and picked up by the silicone pad.

r

• Transfer to Object: the pad deposits the ink onto the surface to be marked, even if it is curved or irregular.

r

• Drying: the ink dries naturally or with the aid of an appropriate drying system depending on the application.

r

• Production: fine adjustment of positioning and initiation of substrate marking to obtain precise and repeatable results.

Pad printing production rates by series:

• Manual : ideal for small batches or prototypes, approximately 100 to 500 pieces/hour, depending on the complexity and size of the objects.
• Semi-automatic (Universal) : a compromise between productivity and flexibility, approximately 500 to 1,000 pieces/hour. Part positioning is ensured by the operator and varies according to the size, shape, and number of colors to be marked.
• Automatic : designed for large series and intensive production, up to 5,000 pieces/hour or more. In a fully automatic configuration, the production rate directly depends on the automation system and its design, as well as the number of colors and the complexity of the marking.

The pad-printed product can be handled quickly, but the drying time depends on the substrate and the type of ink used.

• Fast Plastics: Certain materials like ABS allow for very rapid drying. The marking is dry to the touch in 2 to 3 seconds, and the product can be immediately packaged. However, full mechanical and chemical resistance (abrasion, solvents, etc.) is only achieved after a few hours of stabilization.
• Usage Precaution: Avoid rubbing or intensive handling before the ink is completely stabilized to ensure its durability.
• Slower Substrates: Materials like glass or metal generally require a longer drying time, often 48 to 72 hours.
• Drying Acceleration: Using an oven or high-temperature drying can reduce this time.

The Pro range in pad printing is designed to meet the demands of advanced industrial production, offering a high level of flexibility and integration.

• Advanced Automation: allows for complete integration into automated production lines.
• Open Architecture: features industrial inputs/outputs (I/Os) facilitating communication with external equipment.
• High Production Capacity: suitable for high speeds and intensive production runs.
• Marking Versatility: manages 1 to 6 colors for complex and multi-layer markings.
• Customization: specific design possibilities according to specifications.
• Peripheral Equipment Integration: control of systems such as conveyors, rotary tables, indexers, or surface treatments.
• Industrial Reliability: robust components suitable for continuous operation in demanding environments.
• User-Friendly: access to all essential functions via an intuitive human-machine interface, based on pictograms and available in French.
• Scalable: allows for the addition of accessories and options such as increasing the number of colors, automatic pad cleaning system, corona treatment, or in-line production integration.
• Integrated Print Controller: thanks to the available inputs/outputs, all these peripherals can be controlled directly from the control system.
