Offset Printing

Offset printing is a widely used printing technique that involves transferring ink from a printing plate to a rubber blanket and then onto the printing surface. This process is based on the principle that oil and water do not mix, which allows for precise and high-quality printing. Its features are as follows:


  • High efficiency due to fully automated production line
  • High-quality prints with excellent color effects
  • Precise color matching and positional accuracy
  • Low ink usage and cost-effective
  • Glossy finish and resistant to fading
  • Thin layer of ink reduces costs
  • Automated production line reduces labor costs and increases efficiency


Offset printing is an efficient, high-quality, and cost-effective printing technique that produces clear and detailed prints with excellent color effects. With its fully automated production line and precise color matching, offset printing is an ideal choice for businesses and organizations looking for high-quality prints at a low cost.


In the offset printing process, the penetration of printing ink into the paper depends on the properties of the binder, as well as the printing pressure, speed, and the type and surface properties of the paper used. Different types of ink will show different penetration properties and speeds due to differences in viscosity. The penetration of ink into the paper is important for achieving proper adhesion and drying of the ink layer, as well as for reproducing the desired color tones, glossiness, and resistance to friction.


When the ink's penetration and the paper's absorbency are too strong, it can cause powdering or show-through, leading to a significant decrease in color, glossiness, and resistance to friction. When the ink's penetration is too weak, it can cause the back of the printed sheet to become sticky, and in severe cases, sheets can stick together in stacks.


One of the key aspects of offset printing is achieving accurate registration, which refers to the alignment of different colors and elements on the printed page. This is essential for producing high-quality, multicolor prints. To ensure accurate registration, printers use a process called "trapping," which involves overlapping colors slightly to prevent gaps or white spaces between them.


Another important factor in offset printing is ink-water balance, which is crucial for achieving consistent and even printing. This balance ensures that the ink adheres properly to the printing surface and does not smudge or smear. Achieving the right balance requires careful calibration of ink viscosity, water flow, and other factors.


Offset printing is a versatile and cost-effective printing technique that is used for a wide range of applications, from books and magazines to packaging and marketing materials. With its ability to produce high-quality prints quickly and efficiently, offset printing remains a popular choice for many businesses and organizations.
