What is the basic working principle of lithographic offset printing?
What is the basic working principle of lithographic offset printing?
The basic working principle of lithographic offset printing is that the image and non-image areas are on the same plane, with image areas being hydrophilic and repelling ink, while non-image areas are hydrophobic and attract ink.
What are the application areas of lithographic offset printing?
What are the application areas of lithographic offset printing?
The application areas of lithographic offset printing include magazines, books, brochures, posters, packaging, and printing high-quality images.
What is the working principle of letterpress printing?
What is the working principle of letterpress printing?
The working principle of letterpress printing is that it is a relief printing process, with the image areas raised above the non-image areas. Ink is applied to the raised image areas and then transferred to the paper under pressure.

Study Notes
Lithographic Offset Printing
- Lithography is a planographic printing process, meaning the image and non-image areas are on the same plane.
- Image areas are hydrophilic (water-loving) and repel ink, while non-image areas are hydrophobic (water-repelling) and attract ink.
- The process involves dampening an inked plate with water, resulting in ink transfer to paper only in image areas.
- Lithographic offset is the most widely used printing process, suitable for various applications including:
- Magazines
- Books
- Brochures
- Posters
- Packaging
- It is ideal for printing high-quality images.
Letterpress Printing
- Letterpress is a relief printing process, where image areas are raised above non-image areas.
- Ink is applied to the raised image areas and then transferred to paper under pressure.
