Understanding Offset Printing
Large-scale printing projects have relied on offset printing for decades to produce high-quality, consistent results. This printing technique is where ink is transferred from a metal plate to a rubber blanket and then to the printing surface. It is called “offset” because the ink is not directly applied to the paper but is transferred first to an intermediate surface. Also known as lithography or lithographic printing, this method is widely used for various printing needs, especially for high-volume commercial jobs.
Offset Printing Setup Process and How It Works
Offset printing setup requires a high initial cost to set up the equipment. However, additional units later become less expensive. Now to begin printing, first off all four custom metal plates typically of CMYK (cyan, magenta, yellow, and black (key), or of custom ink colors (most notably Pantone colors) are created as per the requirement of the printing job. Offset printing software plays a crucial role in this process, enabling the image or text to be etched onto these metal plates. The areas meant to be printed are raised, while non-printing areas are recessed.
Next, the plate is dampened with water, which adheres to the non-image areas while repelling ink, to ensure that only the image areas attract ink. Further, the ink is applied to the plate, sticking to the raised, image areas. The inked image is transferred from the plate to a rubber blanket, which allows for a smooth transfer of the image. The paper is then pressed between the blanket and an impression cylinder. As the paper passes through, the image is offset onto the paper.
Offset printing is preferred for high-volume projects where cost and quality take priority over setup challenges.
Defining Digital Printing
Digital printing is a modern printing method that saves you from toiling behind creating plates. It directly transfers digital-based images onto a variety of media surfaces. Unlike traditional methods like offset printing, digital printing does not require any manual setup. Instead, it relies on digital files to produce high-quality prints quickly and efficiently. It has gained immense popularity due to its affordability for short runs, variable data printing capabilities, and reduced waste through print-on-demand.
Digital Printing Setup Process and How It Works
Digital printing is a direct-to-print process and hence requires no fancy setup or equipment to be installed, it simply uses either inkjet or laser technology. The digital files of designs are created or prepared digitally using digital printing software, which can be easily edited and transferred to the printing device.
The digital file is then sent directly to the digital printing press, which interprets the digital data and applies the ink or toner directly onto the printing surface, whether it’s paper, fabric, or another material.
After printing, additional finishing processes like cutting, binding, or laminating can be applied, depending on the specific requirements of the print job.
