The lifespan of an ink squeezing blade is affected by several factors, generally ranging from a few months to about a year.
First, usage frequency is a crucial factor. If used intensively every day, frequently scraping ink, the blade will wear out quickly, resulting in a shorter lifespan of about a few months. Conversely, if used infrequently and intermittently, wear will be slower, potentially extending the lifespan to about a year.
Second, the type of ink used also affects the blade's lifespan. Different types of ink have varying viscosity, hardness, and other properties, leading to different levels of wear on the blade. For example, some highly viscous and hard inks cause greater wear, shortening their lifespan; while less viscous and softer inks cause less wear and may have a longer lifespan.
Furthermore, the material and quality of the blade also influence its lifespan. High-quality blades are typically made of wear-resistant and corrosion-resistant materials, possessing good hardness and toughness, better resisting ink wear and scraping, resulting in a longer lifespan. Some lower-quality doctor blades may wear down and deform easily, resulting in a shorter lifespan.
In general, the lifespan of an ink doctor blade ranges from a few months to about a year, depending on factors such as usage frequency, ink type, and the material and quality of the blade. To extend the lifespan of an ink doctor blade, proper usage methods and maintenance measures should be observed, such as avoiding excessive scraping and promptly cleaning ink residue.
