colour offset printing
Colour offset printing represents a sophisticated printing method that transfers ink from a metal plate to a rubber blanket before applying it to the printing surface. This indirect printing process ensures superior image quality and consistent results across large print runs. The technology operates on the principle of oil and water repulsion, where the image area attracts oil-based ink while repelling water, and non-image areas do the exactly opposite. Modern colour offset printing typically employs the CMYK (Cyan, Magenta, Yellow, and Key/Black) colour model, enabling the reproduction of vibrant, full-colour images through the layering of these four basic colours. The process begins with the creation of separate printing plates for each colour, followed by precise registration to ensure accurate colour alignment. This printing method excels in producing high-volume materials such as magazines, newspapers, brochures, and packaging materials, offering exceptional colour accuracy and detail reproduction. The technology allows for printing on various substrates, including paper, cardboard, and certain plastics, making it versatile for different applications. Additionally, the setup costs become more economical as the print volume increases, making it particularly advantageous for large-scale production runs.
