Whether for internal use, such as inventory management, or for consumers, who may need to distinguish between similar medications, product recognition is vital. The machine’s capability to print on either or both sides of a tablet or capsule, in different colors, provides flexibility and clarity in product labeling.

In cases of poisoning or overdose, having clearly identifiable tablets and capsules can help medical professionals act quickly and effectively. Furthermore, the visual imprinting also aids in identifying specific drugs or dosages, making it easier for customers and healthcare providers to recognize and differentiate products.

2. Product Differentiation

One of the major roles of a tablet or capsule printer is product differentiation. In a market where many tablets and capsules may look similar in size, shape, and color, printers help to distinguish one product from another. Manufacturers can print identifying logos, names, or other marks that differentiate products that might otherwise be indistinguishable by sight alone.

In particular, tablet and capsule printing machines can distinguish between capsules of the same size and color, which is especially important in preventing confusion or mistakes in drug administration. The printer can mark capsules either radially around the capsule or along the length of the capsule, ensuring easy recognition.

3. Increased Customer Loyalty

Product recognition through printed identification marks can increase customer loyalty. When a customer can easily recognize a product, they are more likely to trust the brand and remain loyal to it. Having a unique imprint or logo also strengthens brand identity, which is crucial in a competitive market.

Moreover, clear identification can reassure customers that they are consuming the correct medication, thereby improving their overall experience with the product.

Tablet and Capsule Printer Features and Options

Tablet and capsule printing machines come with a range of printing options that cater to various manufacturing needs. Common printing options include:

• Single color on one side: Printing a single color, typically black or a dark shade, on one side of a tablet or capsule.
• Double colors on both sides: Some printing machines allow for two colors to be used on both sides of the tablet or capsule, increasing visual appeal and readability.
• Multiple shapes and sizes: Tablet and capsule printers are versatile and can handle different tablet and capsule shapes and sizes. They can print on round, oval, or other custom shapes, giving manufacturers more flexibility in product design.

Size Limitations of Tablet and Capsule Printers

Tablet and capsule printers do have size limitations, which may vary depending on the specific machine. The size of the machine and the type of printing technology used will determine the maximum and minimum sizes of tablets and capsules that can be printed. Larger machines tend to be able to accommodate larger tablets or capsules, while smaller machines are typically used for more compact products.

Main Components of Tablet and Capsule Printers

Several key components make up a tablet or capsule printer. These include:

• Feed System: This system helps in the automatic delivery of tablets and capsules to the printer. It includes feed discs, rotatable shafts, and gears to ensure the smooth movement of capsules through the machine.
• Hopper: The hopper stores and directs the flow of tablets or capsules to the printing station. It ensures that an adequate number of tablets or capsules are always ready for printing.
• Inking and Printing System: This part includes rotatable rollers, gravure rolls, and offset rolls that apply ink onto the tablets or capsules. This system is responsible for ensuring accurate and precise imprinting.
• Ink Reservoir: The ink reservoir holds the ink used for the printing process. It ensures a constant supply of ink to the printing system.
• Doctor Blade: This sharp blade helps to remove excess ink from the gravure rolls, ensuring that only the required amount of ink is transferred to the tablet or capsule.

How Tablet and Capsule Printers Work

Tablet and capsule printers use an offset printing process to apply ink to tablets and capsules. The process begins by engraving the desired characters or symbols onto a metal cylinder, typically made of stainless steel or brass. This engraved cylinder then rotates through ink reservoirs, where it collects ink in the engraved areas.

The cylinder then makes contact with a rubber offset roll, which transfers the ink onto the tablets or capsules as they pass beneath it. Once the ink is applied, the tablets and capsules move along a conveyor belt, allowing the ink to dry before they are ready for the next phase of production.
