Choosing a Pad Printer

Choosing a Pad Printer

A pad printer is a versatile decoration technology that can be used on multiple substrates and is ideal for printing precise, high-resolution images onto complex or cylindrical products.pad printer Its flexibility, compatibility, cost-effectiveness, and multiple color options make it a preferred decoration solution for many companies. In addition to its versatility, the process is ideal for printing on recessed, curved or uneven surfaces.

The key to maximizing pad print decoration performance is the selection of a high-quality ink, pad, and system.pad printer The right ink, pad, and machine work together to provide superior decoration quality that generates significant time and cost savings.

Ink: Inks come in a variety of colors including standard black and white.pad printer They also allow for a wide range of Pantone color matching options. Ink additives are available to help achieve the desired color properties, such as diluents to adjust viscosity and reduce ink consumption, hardeners to increase abrasion resistance of printed images, and extend the life of ink in the printing and drying processes.

Pad: A silicone pad is printed with an image using the printing plate (also known as a cliche).pad printer The pad compresses down on the product to transfer ink from the surface of the printing plate to the part, leaving the inked area on the product and a void in the center where the product sits. The pad is then returned to its home position, the printing plate is etched, and another cycle begins.

With the growing number of applications that require conductive inks for electrical signaling, pads and printing inks have been developed to handle these demands. Conductive inks allow for printing on a variety of different materials and provide valuable functions such as RFID scanning; identifying and protecting circuitry from electromagnetic and radio-frequency interference, and dissipating static.

When choosing a pad printer for these applications, it is important to consider the process control that can be achieved by using an all-electric system versus pneumatic machines. An all-electric machine gives the operator independent, digital control of pad stroke distances and speeds in all axes of motion as well as programmable delays in fractions of a second at the beginning and end of each axis of movement. This gives the operator greater control of machine operation and allows for more efficient system performance compared to older, pneumatic machines. Energy efficiency is another key factor to consider. Using a pneumatic pad printing machine can consume up to 2.7 natural liters of compressed air per hour. Considering the high cost of electricity and the associated fees that most power companies tack on to the commercial rate, this is a substantial amount of wasted energy. An all-electric machine can run at the same speed, with the same cycle times, while consuming significantly less energy. This translates into huge savings in operational costs over time. For example, an all-electric, multi-color pad printing system with integrated rotary automation can achieve a 50% increase in production over a conventional pneumatic machine.
