When you get into the printing business, you want to make sure you understand every component that could affect the outcome of your jobs. So here is some knowledge to help you become familiar with doctor blades.
What’s the Difference Between Metal and Composite?
While you can generally use blades made from metal for the same applications as composite ones, their features have some critical differences. Metal is usually used because of its ability to provide a clean wipe. Additionally, they are strong, so they hold an edge for a long time. Meanwhile, plastic is used when you need extra flexibility to get a clean wipe. Their flexibility also makes them desirable when you want to avoid scoring on your anilox roll.
What Do the Different Edge Shapes Mean?
Generally, you’ll see different edge shapes accompanied by a degreed bevel angle. In sum, the smaller the degree or, the sharper the tip, the longer the edge will hold, so you can continue using that blade. That’s an excellent investment when you take a long printing job that requires you to print intricate details, such as preliminary structural design plans.
Can Metal Score Your Anilox Roll?
It depends on what your anilox roll is made out of and how often you use it. For example, metal can be used for those coated with industrial ceramic, although lesser-quality materials that you may find can experience scoring. Additionally, if you only use your roll with metal periodically, you shouldn’t have to worry about scoring. However, if you use a cheaper one or print constantly, you could experience scoring from metal.
Can You Choose Between Different Types of Composite and Metal?
So far, you’ve seen the mention of composite and metal blades. Within these categories, you can choose between several different types of metals and plastics so that you can find the best material for your job.
As you can see, there is a lot to learn about doctor blades. Fortunately, by memorizing this information, you’ll be on your way to providing customers with high-quality prints.
