Offset Printing
Offset printing, also known as lithography, is a widely used printing technique that involves the transfer of ink from a printing plate to a rubber blanket and then onto the printing surface. This indirect method distinguishes offset printing from direct methods, such as letterpress or flexography. In the offset printing process, the image or text to be printed is first transferred onto a plate, typically made of aluminum. This plate is then dampened with water and inked. The water adheres to the areas without the image, while the ink adheres to the image areas. The inked image is then transferred from the plate to a rubber blanket and finally onto the printing surface, often paper. This process allows for high-quality, consistent prints with sharp details and vibrant colors. Offset printing is particularly well-suited for large-volume printing jobs, such as newspapers, magazines, and commercial printing, where efficiency and cost-effectiveness are crucial. Additionally, the ability to use a variety of paper types contributes to its versatility, making offset printing a preferred choice for a wide range of printing applications.
