2.3. Key Techniques of Digital Printing on Metal Ornamental Accessories
2.3.1. UV Printing (Ultraviolet Printing)
UV printers employ inks that are rapidly cured by ultraviolet light, enabling them to print on a wide range of materials, including non-traditional materials like glass and metals. This technique of printing provides high-quality prints with excellent scratch resistance and is particularly suitable for surfaces that are challenging to print on using traditional ink absorption methods.
This is one of the modern printing techniques that relies on ultraviolet (UV) light to instantly and rapidly cure the ink immediately after printing. A special type of ink containing a compound that reacts with UV light is used to achieve a strong cure. This type of printing provides vibrant colors, high quality, and accurate details

[19]
(i). Material Preparation Process
The surface to be printed on (such as plastic, paper, glass, metal, or other materials) must be properly prepared and specifically treated for UV printing to ensure that the ink adheres perfectly.
(ii). Ink Application Process
Special UV ink, containing compounds that react with ultraviolet light, is used to rapidly cure the print on the material.
(iii). Ink Curing Process
After the ink application process, the material is passed through a UV curing unit, where the ink is dried and fixed onto the desired surface. The curing process occurs rapidly, reducing production time and enhancing the efficiency of the printing process.
2.3.3. Features of UV Printing
(i) High-Quality Printing
UV printing produces sharp, vibrant colors with accurate details, making it ideal for applications that demand high quality.
(ii) Rapid Curing
The ink is cured instantly when exposed to ultraviolet light, reducing wait times and increasing production capacity.
(iii) Versatility and Surface Variety
UV printing can be applied to a wide range of smooth, non-porous surfaces with closely spaced particles, such as glass, plastic, and metal, offering great flexibility in printing applications.
(iv) Durability and Longevity
The UV ink provides high resistance to abrasion, chemicals, and various forms of radiation, ensuring that the print on the material is durable and long-lasting

Here are some examples of UV printing on metal specifically for advertising purposes:
Figure 5. The figure shows UV printing for advertising applications. (UV Printing on Metal 101, A Basic Knowledge Guide - KDM Fabrication, n.d).
2.3.4. Thermal Printing
This technique utilizes a thermal printhead to apply prints onto heat-sensitive paper or a ribbon coated with ink, producing visible text or images. It is well-suited for rapid and cost-effective printing. It is also used in digital printing applications on metal, as well as for ornamental accessories, signs, receipts, labels, and a variety of other uses.
1) Sublimation Printing
Sublimation printing is a technique that involves transferring the ink from a solid state directly to a gaseous state without transitioning through a liquid state. Such a process is accomplished by applying heat and pressure to transfer paper that has been printed with sublimation ink, where the ink sublimates from the paper and permeates the surface of the material, infiltrating its pores, resulting in durable print that is highly resistant to external environmental factors.
The researcher then proceeds to explain the steps of the sublimation printing process:
2) Design Creation
Design creation is accomplished through the use of advanced digital design software such as Photoshop or Adobe Illustrator, which enable designers and artists to develop intricate and complex designs, which can then be printed with the utmost precision and highest quality.
3) Printing Process
The printing process involves utilizing a specialized thermal transfer printer with sublimation paper. Sublimation inks, designed to transition from a solid to a gaseous state under high temperatures, must be used, enabling the precise transfer of the design onto the material, ensuring high fidelity and optimal quality of the final print.
4) Preparation of Materials
The materials intended for printing using this technique are diverse, including polyester fabrics, polymer-coated metals, ceramics, and plastics. As the material must be properly prepared to ensure optimal adhesion of the sublimation ink. For cloth, it is imperative to ensure that they are thoroughly cleaned and free from wrinkles. For ceramic or metal materials: it is imperative to ensure that they are devoid of oils, dust, or other contaminants that could affect the quality of the print.
5) Ink Transfer
After preparing the design and the transfer paper for printing, the printed paper with the sublimation ink and the required design is placed on the surface of the material to be printed. The paper is then secured to prevent movement during the printing process. A heat press machine is used to apply high levels of heat and pressure to both the paper and the material simultaneously. This heat and pressure cause the ink to transition from a solid to a gaseous state, allowing it to permeate the surface of the material and permanently bond with it. This process typically takes a few minutes, depending on the type of substance and ink used.
6) Finalizing the Print (Product Output)
Once the ink transfer to the desired material is completed, the surface is left to cool. The paper is then quietly and carefully removed, revealing the final print. The result is a high-quality, permanent print with vibrant colors and precise details.
2.3.5. Features of Thermal Transfer Printing
Thermal transfer printing is known for its durability and resistance to external factors, such as repeated washing (for clothing) and exposure to sunlight. This makes it suitable for a wide range of applications, including clothing and ornamental accessories, decorative cups, signs, and promotional products). This enhances its distinction in practical and creative applications.
Examples of thermal Transfer Printing Applications:
(i). Printing on Metal Medals
This technique can be used to print custom designs or unique images onto metal medals. In this process, the desired design is printed onto a special transfer paper using heat transfer ink. The paper is then placed on the metal medal, which is coated with a special layer of alkyd or polymer. The medal is then subjected to heat and pressure using a specialized machine. The heat transforms the ink into a gas, allowing it to permeate the designated layer on the metal surface, resulting in a precise and durable design that won’t wear off.
Figure 6 shows an example of printing on metal medals, showcasing double sided gold/ silver sticker papers specifically designed for medals and badges.
Figure 6. Example of printing on metal sheets (medal). (Double Sided Gold/Silver Sticker Sheets - For Medals and Trophies - Inkjet - IFF (iffstore.com), (n.d)).
(ii). Printing on Metal Medals
Thermal transfer printing is used to print designs or text on metal medals intended as gifts or awards. Initially, the design is printed onto transfer paper. This paper is then wrapped around the medal and secured with adhesive tape. The medal is subjected to heat and pressure using a small oven or specialized machine. The solid ink converts to gas and interacts with the metal surface, which improves the design's durability and resistance to wear and scratches.
Figure 7 shows a printed metal medal using the thermal transfer technique.
Figure 7. The figure shows a printed metal medal using the thermal transfer technique. (Sublimation Jewellery, Sublizon, n.d).
(iii). Printing on Metal Bottles
Designs can be printed on metal bottles, such as water bottles and other products, for use as promotional products or gifts. The design is first printed onto transfer paper, which is then placed on the surface of the metal bottle. The bottle is then exposed to heat and pressure using a specialized machine. This process allows the ink to interact with the metal surface, resulting in a high-quality, durable design on the product.
2.3.6. 3D Printing
This method is an innovative technique that enables the manufacturing of unique pieces in limited or small quantities. It involves constructing a three-dimensional model layer by layer using specialized materials, such as plastic, metals, or others as desired. The process relies on digital design with CAD software, which divides the model into very thin layers. The dedicated printer then builds the shape layer by layer with utmost precision, regardless of the material used, until the final shape is complete. This technique facilitates the production of high-quality, detailed, and complex customized models
