What is pad printing?
Pad printing, also known as tampo printing, is a versatile printing technology that uses a flexible silicone pad to transfer ink from a cliché or printing plate to numerous objects or substrates. It is frequently used to print on three-dimensional surfaces, irregular forms, and materials that are difficult to print on with other traditional printing processes. This is a versatile and adaptable method for printing on irregularly shaped surfaces like curved or textured objects.
Pros and cons of pad printing
Pros of pad printing
Versatility: Pad printing is suitable for a wide range of substrates, including polymers, metals, glass, ceramics, fabrics, and others. It adheres and lasts well on a variety of materials.
3D printing: Pad printing, unlike other printing techniques, can print on curved, uneven, or textured surfaces, making it ideal for things with complex curves or contours. Pad printing produces good results whether printing on golf balls or intricate shaped medical devices.
High resolution and fine details: Pad printing is ideal for delicate designs, small text, and logos with intricate patterns because it enables for high-resolution printing and exquisite detail.
Cost-effectiveness: Pad printing equipment and consumables are generally inexpensive when compared to other printing processes, particularly for small to medium production runs.
Durability: Pad printed prints are extremely robust and resistant to abrasion, fading, and environmental conditions, ensuring long-term excellence.
Cos of pad printing
Color restrictions: Pad printing is best suited for designs with a restricted number of colors, often one to six. Complex multi-color designs may necessitate many passes or additional setups, lengthening manufacturing time and increasing costs.
Production rate: Pad printing is typically slower than other printing technologies such as screen printing. Multiple processes are involved in the process, including ink application, pad printing, and drying time, all of which can affect output speed.
Print size restrictions: Pad printing is often utilized for print areas ranging from tiny to medium in size. Because the size of the silicone pad and cliché may be limiting considerations in large-scale printing, additional solutions may be required. Pad printing equipment will struggle with image sizes larger than 150mm in diameter.
Selection of ink: Pad printing requires careful ink selection to provide optimal adhesion, color vibrancy, and durability. Experimenting to discover the proper ink for your individual substrate and design requirements may be necessary.
How does pad printing work?
Preparation of artwork
Pad printing is suitable for a wide range of substrates, including polymers, metals, glass, ceramics, fabrics, and others. It adheres and lasts well on a variety of materials.
The design is transferred to a metal or polymer plate by a chemical etching process or laser engraving, which is called a cliché.
Fill the ink cup with ink and dip the writing in it. Remove excess ink with a squeegee, leaving ink solely in the etched regions.
Transfer of ink
This necessitates the usage of silicone pads, also referred to as transfer pads.The silicone pad needs to be pressed against the cliché to pick up the ink from the etched area.
The etching plate is withdrawn, bringing the inked silicone pad towards the object or substrate to be printed and pressing against it, transferring the ink to the object’s surface.
Drying and curing
Place the printed item in a dry location; depending on the ink used, the printed object may require varied drying times and methods. Air drying, heat curing, and UV curing are all techniques of curing.
What is pad printing used for?
Pad printing is widely used to print on a wide range of materials such as plastics, metals, glass, ceramics, and even fabrics. It is extensively used in the automobile, electronics, medical equipment, promotional products, and consumer goods industries.
Promotional products: Pad printing is a popular method for printing logos, branding features, or unique designs on promotional goods such as pens, key chains, USB drives, mugs, and other freebies.
Electronic products: Many electrical equipment, such as keypads, remote controllers, and phone covers, necessitate accurate and long-lasting printing. Pad printing is ideal for printing on unevenly shaped electrical component surfaces.
Automobile industry: Pad printing is commonly used in the automotive industry to attach labels, insignia, and emblems on dashboards, buttons, knobs, and other interior and external car components.
Medical instruments: Pad printing is used in the medical industry to brand medical devices and equipment such as syringes, catheters, dialysis machines, and prosthetics. Pad printing inks are often resistant to sterilizing treatments.
Toys & games: Toys, puzzles, game boards, and playing cards are frequently printed with designs, characters, or safety notes using pad printing.
Glassware and ceramics: Pad printing can be used on glassware, ceramic cups, and plates for detailed and exact printing. Pad printing, for example, is used to print numerous patterns on ceramics.
Sports equipment: In the sports sector, pad printing is used to add logos, brand names, or marks on equipment such as golf balls, hockey sticks, helmets, and tennis rackets. Aerospace and industrial components: Pad printing is used to mark and mark aeronautical components, industrial tools, control panels, and other mechanical elements.These are just a handful of the numerous applications for pad printing. Its adaptability, ability to print on a wide range of materials, and handling of complex geometries make it a valuable printing process in a wide range of sectors.

Finally, pad printing is a versatile and efficient printing process that may be used on a variety of surfaces and applications. Pad printing, with its capacity to print on irregular forms, three-dimensional surfaces, and a variety of materials, provides organizations with the flexibility to accomplish precise and long-lasting printing. JetPrint does not currently use pad printing products. Instead, we rely on sublimation, thermal transfer, and UV printing.
