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.

Using Real Cleen Solutions for Press Cleaning

The importance of purchasing the right cleaner for your presses cannot be understated. Since a lot of ink goes into large-scale and industrial printing, it is going to take an impressive cleaning solution to ensure all dried on ink is removed to ensure a high-quality print every time. But how do you decide which press cleaners will best meet your needs? Here at Allison Systems, we fully recommend checking out The Flexo Factor’s “Real Cleen” solution as a starting point.

The Real Cleen Advantage

Beyond being a popular choice for most press equipment, The Flexo Factor’s “Real Cleen” solution is water-soluble and contains lubricants and rust inhibitors to help protect the equipment you’re cleaning. Furthermore, this solution is designed to remove dried inks from equipment surfaces on contact. This works for water, glycol, and UV ink applications.

Specs and Usage

You can purchase this solution in either ready-to-use or concentrated forms. This liquid has a pH 1% solution rating of 10.3 to 10.8 and is amber in color. The cleaning solution is environmental and operator safe, though you should always use safety glasses and gloves when handling it. For use, apply and rub it into the surface you are cleaning, and then rinse with water. When not in use, keep the container closed tightly and rinse any empty containers before disposal.

If this solution doesn’t provide you the results you need, you can check out many of the other press cleaners provided by The Flexo Factor. We’d be happy to supply you with our recommendations at your request.
