Letterpress vs flexo: when to use which technology?


< Blog overview

In the label industry, there are mainly two factors that determine which printing technique is best for your company: quality and cost price. With many technologies to choose from, it may sometimes be hard to determine which technology fits your business best.

As every printing job requires a different set of needs, there are several factors to be taken into account when choosing the right printing technology.

Two technologies that are often compared are letterpress and flexo printing. In this blog, I’ll explain the way those two technologies work, and list some advantages and disadvantages of both.

Letterpress printing

The classic letterpress technology

Letterpress printing: the process explained

Letterpress printing is a relief printing process that initially utilized raised metal type and engravings to imprint words and designs on a page. It originated in the 1400s and was the primary form of printing for over 500 years.

Letterpress print plates are inked over an ink roller set, controlled via ink-key settings. The image is transferred directly from the plate to the substrate using pressure.

In letterpress, graphics are built using dots - the smaller the dots, the lighter the color; the larger and closer the dots are, the darker the color.

Advantages of letterpress printing

Cost-efficiency of the letterpress printing process is a key factor in considering which printing press is more suitable for your business.

  • Low tooling costs
  • Fast change-overs
  • High print quality
  • Ideal for small jobs 

Flexo printing: the process explained

Flexography is a relief or raised image printing process using the same principle as letterpress. A flexible rubber or photopolymer plate is mounted onto the plate cylinder. The plate image is inked with a liquid ink which is transferred from the anilox roller, direct to the surface of the image area and then printed onto the substrate, using a very light controlled pressure (impression).
