In the context of printing, "pad" refers to a specialized printing technique known as pad printing. Pad printing is a versatile and precise method used to transfer ink from an etched plate (also called a cliché) onto a three-dimensional object or substrate. The pad, also called a silicone pad or transfer pad, plays a crucial role in this process.
Here's how pad printing works:
1. Etched plate preparation: An image or design is etched onto a metal plate, creating recessed areas that hold the ink.
2. Ink application: The etched plate is coated with ink, and a doctor's blade or scraper removes the excess ink, leaving ink only in the recessed areas.
3. Pad transfer: The silicone pad, made of a flexible and deformable material, is pressed onto the inked plate, picking up the ink from the recessed areas.
4. Ink transfer: The pad is then pressed onto the object or substrate, transferring the ink from the pad onto the surface. The pad conforms to the shape of the object, allowing for printing on irregular or curved surfaces.
The pad acts as a flexible and resilient medium that transfers the ink from the etched plate to the object. It compresses and then releases, allowing for accurate and consistent ink transfer. The silicone material of the pad ensures that it can conform to various shapes and textures, ensuring precise and detailed printing.
Pad printing is commonly used for printing on objects with complex shapes or uneven surfaces, such as promotional items, electronic components, toys, medical devices, and automotive parts. It allows for precise and high-quality printing on materials like plastic, metal, glass, ceramics, and more.
The pad in pad printing is an integral component that enables the ink transfer process and contributes to the versatility and accuracy of this printing technique.
