Pad Printing

Dip the required ink into surface of a curved silicone rubber pad head, which is then pressed to the surface of the required object, to print text, patterns, etc. Continuous multi-color printing, high output, quick speed, and no drying time are all possibilities. It has the ability to print on a variety of materials, including plastic, metal, ceramic, leather, and others.


The fundamental idea for Pad Printing is that the ink from the pad printing machine is first applied to the steel plate's engraved text or pattern before the text or pattern is transferred onto the rubber. Text or designs are transferred to the surface of plastic objects using rubber. Heating or exposing the ink to ultraviolet light is the simplest ways for repairing it.

PROCESS of Pad Printing

1

1. Surface Treatment

The surface must first be cleaned in order for the screen printing ink to adhere. Throughout the process, surfaces are cleaned of grease, dust, and other pollutants, typically through a cleaning agent or stain remover.

2. The production of printing templates

The printing of templates is essential to the Pad Printing procedure. The phrases and patterns that need to be printed must be turned into digital graphics files. The printing template is then made using a Silk Screen or photosensitive plate.

3. Coating Printing Ink

Coating the printing ink is the primary step in the Pad Printing procedure. The printing ink is applied on the printing template to create a pattern or text, which is then pushed onto the plastic bottle's surface. The surface of the bottle body is then scraped with the printing ink.

4. Dry Processing

When coating is finished, the printing ink must dry. To make sure the printing ink is firmly bonded to the component's surface, heating and drying equipment is frequently utilized.

5. Quality Control

The process ends with a quality check to ensure that the text and printing patterns are clear and free of errors. If there is a mistake, it needs to be corrected or redone.

DIFFERENCE BETWEEN Pad Printing and Silk Screen

  • Pad Printing ink fineness is more finer than Silk Screen.

  • Pad Printing oil has better ink density and coverability than Silk Screen.

  • Ink dries more quickly for Pad Printing than for Silk Screen.

  • Compared to a Silk Screen, a Pad Printing's ink silk head is shorter.

  • Pad Printing's ink layer is generally more thin than that of the Silk Screen, which has a thicker ink layer.

  • When using a multi-color Pad Printing machine, a multi-color overprint can be completed, although the Silk Screen's efficiency is low.

  • Silk Screen features mesh serrations, but Pad Printing has not.

Applications

Pad Printing Applications

As was previously noted, Pad Printing can be applied to nearly any substrate material. The most common uses for pad printing are often on plastic and metal. Pad printing has become popular because of its adaptability and capacity to reproduce fine details in:

  • Cables, connections, and other components component of consumer electronics.

  • Coffee makers and TV housings are examples of household products.

  • Calculator and computer keyboard buttons and keys, etc.

  • Toys, baby bottles, pacifiers, etc.

  • Sports equipment includes golf balls and footballs.

  • Numerous additional components.

Advantages of
Pad Printing

  • The silicone rubber pad printing head is flexible and may be positioned twice or three times in the surface to print on substrates with concave and convex surfaces.

  • With Pad Printing, designs can be printed more precisely; typically, a 0.05mm fine line can be produced.

  • Printing accuracy won't change because technology has been around for a while.

  • Remove the drying procedure to enable multicolor printing.

  • With concave and convex appearance precision for monochrome, double-color, or color graphic printing, a wide range of information goods can be printed. Another choice is soft contact printing, and it's also feasible to print on fragile and soft goods.
