How to choose screen printing blade
For screen printing, here are something we need to prepare. Good quality screen printing mesh is important, and choosing the right screen printing blade is also important. Here are some things to keep in mind when choosing a screen printing blade for the printing job at hand:
Handle: When printing by hand, choose the comfort that suits your hand. There are many types to choose from, including wood, plastic or metal. Some are ergonomically designed.
Screen printing blade shape: There are three different types - square, round and v-shaped.
Square (straight edge) blades are most commonly used for screen printers. They are suitable for standard or general ink applications.
The round (ball nose) scraper blades deposit more ink. Use this type of special effect ink such as gel or puff.
V-shaped (single bevel or double bevel) blades are typically used for printing on irregular or cylindrical substrates.
Hardness tester: indicates the hardness of the blade.
The 50-60 hardness tester is a soft blade that can deposit more ink. This durometer is chosen for heavier textured fabrics to place more ink (which may help with fiber flutter) or for special effect inks such as gels and puffs.
The hardness is marked as a 60-75 hardness tester. Suitable for general printing.
The most difficult choice is an 80-hard blade. It reduces ink deposits and is ideal for printing fine or four-color printing processes.
Composite blade: This blade blade consists of different blades that are clamped together by one or more different durometers, such as 60/90 or 70/90/70. The benefit of using this type is that the hardness tester gives great support to the squeegee, but has a softer edge print.
Hope the passage is helpful for you when choosing screen printing blade.
