What is Offset Printing?
Offset printing is an indirect printing technique that is widely used for the production of high-quality printed materials on a large scale. The name "offset" comes from the fact that the ink is not transferred directly from the plate to the paper, but passes through an intermediate blanket-coated cylinder, which transfers it evenly over the printing surface.
This technology is now one of the most widely used in the commercial printing industry and is used for books, magazines, newspapers, catalogs, packaging and print advertising.
Working Principle
Offset printing follows the principle of repulsion between water and oily ink. The process takes place in several phases:
- Plate preparation
- The plate is made of aluminum and is chemically treated to make the ink adhere only in printable areas, while non-printing areas attract water.
Plate inking
- The plate is mounted on a metal cylinder and is first moistened with water, which adheres to the non-printing areas, and then inked with an oil-based ink. Because oil and water do not mix, the ink only adheres to the print areas.
Image transfer to the rubber cylinder
- The inked image is transferred from the plate to the rubber-coated intermediate cylinder . This intermediate step helps to distribute the ink more evenly on the paper, avoiding wear and tear on the plate and ensuring consistent quality over time.
Transfer to the card
- The rubber cylinder presses the ink onto the paper, ensuring even coverage even on rough surfaces.
Drying and finishing
- The print is then dried, trimmed and processed according to the desired final product.
Materials Used
- Aluminum plates: chemically treated to retain ink only in desired areas.
- Rubber cylinder: intermediate between plate and paper to ensure optimal transfer.
- Oil-based or UV-based inks: for fast drying and high colour rendering.
- Coated paper, uncoated paper, cardboard: suitable for different printing needs.
Common Applications
Offset printing is used in a number of industries to produce quality materials, including:
✅Publishing: books, magazines, newspapers, catalogues.
✅Advertising materials: flyers, brochures, leaflets.

If you need to print brochures, business cards, Personalized, on-demand promotional materials, or high-quality photo prints, digital printing is the best choice.
What is Screen Printing?
Screen printing is a permeography printing technique that uses a frame with a stretched fabric to transfer ink onto the paper. It is particularly appreciated for the possibility of applying special effects and special finishes, such as metallic inks, reliefs and thick paints.
This technique is ideal for printing on luxury packaging and art papers, thanks to the ability to print on materials of alto thickness and extremely opaque and bright colors.
Working Principle
Screen printing works through a process of filtering ink through a frame. The procedure is divided into several phases:
- Preparing the Frame
- The frame is made of a fine knit fabric (formerly silk, today usually polyester or nylon) mounted on a rigid aluminum or wood frame.
- A photosensitive emulsion is applied to the frame and subsequently exposed to light with the desired design. Areas exposed to light harden, while those covered by the image remain washable, thus creating the stencil.
Ink Application
- Once the stencil is ready, the ink is poured onto the top of the frame.
- A doctor blade (a rubber spatula) is used to push the ink through the open parts of the stencil, transferring it directly to the substrate below.
Drying and finishing
- The ink is dried at room temperature or with UV drying systems to ensure greater resistance.
- Subsequently, special finishes such as glossy painting, relief or lamination can be applied.
Materials Used
