There are some marking jobs where it is not just about printing text using straight lines on plain metallic sheets. There are many other parts that are curved, textured, oddly shaped, and even delicate that require a marking process which can bend the ink around these contours without harming the substrate material. This kind of marking process can be done efficiently by tampo printing.
Tampo printing services is just another name for the pad printing process, in which a soft silicone pad is used to transfer ink from an engraved plate to the substrates, irrespective of their shape. This is one of the few processes which can reproduce details and logos of different colors in addition to printing text.
What Makes Tampo Printing Different from Other Methods?
The essential part of tampo printing is the pad. Due to its flexibility, it can do the following:
- Adjust to convex, concave, and irregularly shaped substrates
- Apply the ink without exerting too much pressure to prevent damaging the substrate
- Print fine details, tiny letters, and multicolor designs without distortion
- Function on many different substrates, including metals, plastics, and glasses
In contrast to the flat surface processes such as screen printing, tampo printing excels in cases where the substrate is three-dimensional.
Where Precision Really Counts: Medical Applications
No other industry calls for greater accuracy than that of medical device manufacturing, and this is where the process really shows its value. Pad printing for medical devices is used for printing devices, instrument housings, and components that need to be marked precisely and legibly, oftentimes on a very small scale.
Here, medical marking requires more precision than any other industry:
- It needs to stay legible even after multiple rounds of sterilization
- The marks are usually extremely small and have strict registration demands
- It involves many different materials, from stainless steel to medical-grade plastic materials
- There are many regulatory requirements for what exactly should be printed and how
Any process that is off by just a little bit, blurs fine lines of text and fades after a couple of autoclaving cycles, will not suffice in this field. This is why medical manufacturers choose pad printing for its precision and reliability.
Is Precision Marking Right for Your Parts?
Here are some questions that can answer whether tampo printing is ideal for the task:
- Is the part curved or uneven?
- Is there any fine print, codes or graphics that require printing?
- Does the surface have to remain unaffected by the pressure or heat of the printing process?
- Does the print have to withstand cleaning or sterilization processes?
If most of these conditions are true, then the standard flat surface printing process will not do, but the printing process that uses the conforming pad will be perfect.
Features and Benefits Beyond Medical Use
Though medical marking is a great example, this kind of marking shares these attributes with a number of other uses:
- Versatility: marking can be done on metals, plastics, glass, and composites
- Fine detail: retains fine lines and minute text, which other processes smudge
- Gentle: uses minimal force to mark fragile or previously finished surfaces
- Consistency: reliable results even in large volume runs
These qualities can be seen in a wide range of applications, from electronics to car parts, promotional products to industrial machinery.
What to Look for in a Marking Partner?
Selecting the proper process is just one piece of the puzzle – the team that will be handling the process itself plays an equally crucial role. A proficient pad printing supplier offers more than just machines; they offer years of experience when it comes to combining appropriate inks, etched plates, and pads with the material and form of the product.
Qualities to look for in a good pad printing supplier usually consist of:
- Experience with different types of materials and industries
- Being open to testing and approving samples before full-scale production
- Awareness of regulations and other industry requirements
- Understanding the limitations of certain surfaces/materials
A Closer Look at How This Comes Together
Tampo printing has shown its capabilities in numerous parts, with the exact same underlying process used in each one, including:
- Precision medical parts, where tolerances must be precise
- Complex auto parts, whose shapes must be accounted for
- Consumer products, which require detailed, colorful branding
It is the modification of the process that links all of these processes together – what works perfectly on a plastic housing can work differently on a metal instrument.
Conclusion
The importance of Tampo Printing in the manufacturing process comes from the fact that many items do not have flat or regular shapes. Here are a few things you should remember:
- Medical devices require high precision and are resistant to sterilization in miniature
- Curved and textured items require a process to fit their shape
- Tiny text and multicolor prints last longer using pad printing than the flat surface process
Selecting an appropriate process and an appropriate supplier based on the characteristics of an item is what differentiates a great mark on the first item from the same on the last item. Pad Print USA provides just such a tailor-made service for every product.
