Edge Profiles
The edge of the doctor blade plays a pivotal role in how efficiently it meters ink. The most common edge configurations are straight, bevel, and lamella.
Round Edge
A double-sided radius edge is simple but effective for many standard printing tasks. It provides a high quality seal and is best used in situations where ink film thickness variations are less critical.
Bevel Edge
Beveled blades offer a sharper contact point with the anilox roll, allowing for a thinner ink film. This configuration is preferred for finer print jobs requiring higher resolution.
Lamella Edge
Lamella, or stepped, edges provide the most precise metering by offering a consistent, thin ink film. This type of blade is ideal for high-end printing applications where print quality cannot be compromised.
Function
Doctor Blade used to remove excess ink from the surface of a roller. The ink scraper must be abrasion resistant and efficient to ensure the high quality of printing, and it must be suitable for the durable and high-speed needs of modern intaglio printing.
