Printing presses are the absolute workhorses of the industry, and this is true whether you have a small-scale operation or a large one. Day after day, these presses function almost without interruption. Ensuring a clean output without ink leakage or other problems absolutely depends upon the quality of the parts you’ve chosen to install.
End seals and blade choice do matter, so you’ll want to select the absolute best parts you can afford. If you’re looking for a regular or composite blade, there are a few great options from which to choose. Composite doctor blades are usually made of more than one material and can be incredibly precise.
Metal blades are the most traditional and are generally made of high-quality steel. Carbon steel, tool steel, stainless and white carbon steel are just a few options. These come in a variety of different end shapes and can be rounded or beveled at a specific angle, depending upon your particular needs.
Plastic is a great alternative to traditional metal blades. It is durable, flexible and can be molded exactly to your specifications. This helps ensure maximum output with minimal leakage of ink, which means that your print quality will stay clear and solid. Since precise output is always the goal with printing presses, this makes a plastic blade an excellent choice for many applications.
You may also want to choose a blade made of composite materials, and today’s choices are flexible and varied enough to meet your needs. Containment blades and flexo doctor blades alike are available in composite materials such as fiberglass, graphite, and nylon.
Whichever type of composite blade you decide is best for your printing press, make sure to find a reputable manufacturer that specializes in these types of precision machine parts.
