Picking Your Doctor Blades

Plastic blades being displayed as a fan.Doctor blades are the key to successful production but choosing the best one for your needs is often a complex process.  You need to know your intended application, as well as the advantages and drawbacks of different blade types.  Fortunately, we are here to help. Before you order new blades, consider some of the best uses for two styles you can buy:

  • Metal Blades – The material of choice for high-quality and repeatable doctoring results, these blades come in several forms. Each one has its advantages, such as the long life of tool steel blades or the corrosion resistance of stainless steel. The important thing to remember is that metal should be your go-to for doctoring that’s consistent across numerous jobs.
  • Plastic and Composite Blades – Certain flexo, coating, and gravure applications require cost-effective performance but not necessarily the benefits of metal blades. A couple of examples would be applications that use low screen count anilox rolls or corrugated applications.  You can count on plastics and composites to deliver this performance. These blades tend to have a long life at high speeds and are ideal for use on laser-engraved ceramic anilox rolls.

Are you still unsure which blades you should buy? Don’t be afraid to ask an expert! A reputable supplier should be happy to work with you to determine the best product for your situation.

The Advantages of Steel Doctor Blades

Printing BladesThe doctor blade is a crucial component of the flexo printing and gravure printing processes. It removes ink from the surface of the roller so that the intended volume of ink can be transferred. In this article, we will discuss the advantages of steel doctor blades.

When quality is your production priority, you cannot go wrong with a steel doctor blade. Blades made with this material are specially manufactured so that printing processes generate consistent, high-quality results. Many printers prefer steel doctor blades because they are:

  • Cost-Effective: Carbon steel is highly economical. Its durability makes it an excellent choice for short-run production jobs, as well as projects that use non-porous substrates or inks that are not very abrasive.
  • Durable: Doctor blades crafted from tool steel are designed with longevity and toughness in mind. Abrasive inks, such as white inks or those containing titanium dioxide, solids, or rough anilox rolls, can cause wear and tear due to friction. Tool steel doctor blades can withstand the abuse.
  • Long-Lasting: One significant cost in the printing production process arises from press downtime due to the need to change or adjust the doctor blade.   Many grades/types of steel and edge shapes are available so that you can choose the best option for the application.  Running long life tool steel in high wear applications and other grades in less demanding setups will help ensure that all of the blades will need replacing at the same time.  By replacing blades less often, you will save on production costs.

There are many advantages to running steel doctor blades. Contact Allison Systems to learn more about your options.

Printing Blades for Printing

Printing BladesYour printing job is only as good as the quality of materials that are used to create the product. That applies to every element at each step along the way, from the design to the inks, substrate, and other components to the press itself.

Your printing company can truly only control some of those steps along the way, not the entire journey itself. However, the elements you can control, like the performance of the press, benefit from your full attention to detail and professionalism. When you examine the first piece off the press and the last piece off the press, it’s your ultimate goal for the two to be indistinguishable with the quality just as high from first to last.
