Mechanism of Offset Printing

Offset printing works as a complex process that involves several steps to transfer ink from an inked image onto paper. It begins with digital image transfer to an aluminum plate, where hydrophobic and hydrophilic areas are created. Inking follows, with ink adhering to hydrophobic areas while damping repels ink from hydrophilic areas.

The inked plate transfers the image to a sheet, ensuring even distribution while the sheet transfers the image to paper under pressure. After printing, a drying process sets the image, with optional finishing steps like trimming or binding.

Technology Behind Digital Printing

Digital printing transfers digital data onto paper using liquid ink or toner. The process involves creating a digital file, processing it for compatibility and image optimization, and then transferring it to the printer’s imaging unit (utilizing technologies like lasers or inkjet technology).

The selective application of ink or toner to the printing surface to create the image comes next, followed by the finalizing with development, fixing, drying, and optional finishing steps.
