Printing techniques refer to the various methods used to transfer ink onto a surface, typically paper. Common techniques include offset printing, where ink is transferred from a plate to a rubber blanket and then to paper, and digital printing, which uses digital files to produce images directly on the material. Each method has its advantages, such as cost-effectiveness or high-quality output. Another popular technique is screen printing, where ink is pushed through a mesh screen to create designs, often used for textiles. Letterpress is a traditional method that involves pressing inked raised surfaces onto paper, giving a tactile quality. These techniques cater to different needs in the printing industry.
