Any operation in which printing ink is applied on any surface and then dried is referred to as the printing method. There are 5 main methods by which printing for packaging is carried out.

  • Offset Lithography Printing 
  • Flexography
  • Digital Printing or Inkjet Printing 
  • Gravure
  • Silkscreen Printing 

1. Offset Lithography Printing

Offset Lithography Printing is one of the most common and most versatile of all methods used for packaging printing. A large variety of materials are printed by using this technique. 

Uses

For printing the high-quality promotional materials Offset Lithography technique is used and these materials may include branded coasters, product advertisers and mouse mats etc.

Paper, plastic, wood and metals can also be printed by this technique. Everything (whether it is electronic, digital or print) has advantages and disadvantages as well. It depends on us whether we use it to our advantage or disadvantage.

Disadvantages

As compared to rotogravure or photogravure, offset printing gives a slightly inferior quality of the image. Because of the time and costs required to set up, Offset Lithography is not cost-effective. It is not cost-effective when used for smaller amounts. So, it is usually used when large amounts of print are needed. 

2. Flexography

A form of printing process which applies a flexible relief plate is referred to as flexography. 

Uses

For applying simple designs and colours to a wide variety of packaging materials, this technique is used worldwide.

Advantages

For printing solid colours and patterns on a wide range of substrates, flexography is used. 

Flexographic printing is also applied on porous, non-porous, rough, flat, absorbent and non-absorbent materials. A large number of types of inks can be used in flexography.

In this case, flexography is somewhat a good option for printing as it has fewer effects on the environment than other printing techniques. So, it is eco-friendly as well.

Disadvantages

Flexographic printing on the downside is not very advanced as compared to other methods of printing. Also, complicated and huge artworks cannot be produced by using this technique.

3. Digital Printing or Inkjet Printing

The process of moving a digital file directly to a printer or media substrates is referred to as Digital Printing. 

Uses

The items that demand smaller quantity orders and high amounts of details use digital printing. 

Digital files can be printed on paper, canvas, fabrics and other substrates by sending them directly to the digital printing press.

Advantages
