Blue Metal Doctor Blades Will Meet Your Printing Needs

Choosing the right blade makes all the difference in large-scale and commercial printing. These metal blades — known as doctor blades throughout the industry — control the amount of ink that remains on a printing cylinder. It helps keep ink evenly distributed for a more precise and careful print. There are many to choose from, but we would like to highlight one of the options at Allison Systems: the blue blade.

Why Use Blue Oxide Blades?

Blue doctor blades are made from carbon steel. This material is known to be economical and it can be used for short-run process jobs with non-porous substrates and non-abrasive inks. The blue steel blade itself is made of carbon steel with a blue oxide layer.

The original purpose of the blue oxide was to give the blade makers of a bygone era a better way to identify the bevel of the blade. The bevel is easy to identify because of the contrast between the blue material color and the polished steel edge color. While this treatment is no longer necessary in the manufacturing process, it can still be helpful to more accurately identify the beveled edge to ensure correct installation orientation when the blade needs to be changed.

Blade Specifications

The blue oxide blade is available in 4, 6, 8, 10, 12, 15, 18, and 20 mil thicknesses, with a number of different beveled edges. Some of the bevels only come in certain thicknesses, so make sure you’ve already identified which blade is best for your printing press equipment. If you’re unsure, we’d be happy to help you identify the right metal blades for your equipment.

Durable Gold (QR) Metal Blades

Metal BladesIn printing applications, abrasive inks can wreak havoc on the metal blades that your equipment needs to function. Allison Systems strives to solve this problem by offering a product with exceptional durability, specially created to last as long as possible by employing innovative design. Offering a number of advantages over traditional blades, our Gold (QR) option is available with several bevel options and in thicknesses of:

  • 0.006”
  • 0.008”
  • 0.010”
  • 0.012”

Excellent at enduring abrasive inks, QR blades also serve to reduce scoring issues. As they wear down, they produce smaller particles than other materials – particles that easily flush away from the blade instead of sticking between it and the cylinder. That means less frustration for your team and better results when you print, especially over time. It also translates to less waste from unusable materials.

Value isn’t the QR blade’s only advantage, however. It’s also versatile. Available for use with gravure and flexo doctoring, it also supports containment applications with both chrome and ceramic rolls. With expansive uses and a long lifespan, this product stands out as an excellent choice when you want premium quality and the freedom to make the most of your blades.
