How are aluminium cans digitally printed?
Aluminium cans can be digitally printed using a process called direct-to-shape (DTS) printing or digital printing. Here's a general overview of the steps involved:
Design and Preparation: The artwork or design for the can is created digitally using graphic design software. It can include logos, images, text, and other decorative elements. The design is typically prepared in a specific template that represents the 2D flattened version of the can.
Color Management: Color management is an important aspect of the printing process. Colors are calibrated and matched to ensure consistency and accuracy between the digital design and the printed result. This is particularly crucial for maintaining brand identity and meeting customer expectations.
Printing Technology: DTS printing utilizes specialized digital printing machines designed for printing directly onto three-dimensional objects like aluminum cans. These machines use advanced inkjet technology or other digital printing methods to apply the design onto the surface of the cans.
Surface Preparation: Before printing, the cans need to be prepared to ensure proper adhesion and ink durability. This typically involves cleaning the surface of the cans to remove any dirt, oils, or contaminants that could affect print quality.
Printing Process: The cans are loaded onto the digital printing machine, which applies the design onto the surface. The printing process can involve multiple passes or layers to achieve the desired colors, details, and opacity. The printing machine precisely deposits the ink onto the cans according to the digital design.
Drying and Curing: Once the design is printed, the cans go through a drying or curing process to set the ink. This may involve exposure to heat, ultraviolet (UV) light, or other curing methods, depending on the specific ink and printing technology used.
Quality Control: After printing and drying, the cans undergo quality control inspections to ensure the printed design meets the required standards. This can involve visual inspections, color verification, and other checks to identify any defects or inconsistencies.
Packaging and Distribution: Finally, the printed cans are packaged and prepared for distribution. They can be filled with beverages or other products, sealed, and shipped to retailers or consumers.
It's worth noting that the exact process and equipment used for digital printing on aluminum cans can vary depending on the specific printing technology and manufacturer. Different printing methods may have variations in the printing process, ink types, drying techniques, and quality control measures.
