25*5 Small Swelling Rate Screen Printing Squeegee For Packaging
Choosing The Best Squeegee
For Your Application
DUROMETER AND PRINTING
EDGE (As Related To Ink Deposit)
The lower the durometer, and the less sharp the print edge, the more ink is deposited. The higher the durometer, and the sharper the print edge, the less ink is deposited. The more irregular or rougher the surface of the substrate is, the softer the durometer needed. (And vice versa.) To maximize solvent resistance, always use the hardest durometer that is practical for the particular job. The harder the squeegee, the more dense the urethane and therefore the stronger the chemical resistance.
2. COLOR CODING
Use color coding as a means of fast and easy identification of the correct squeegee durometer once you’ve established the hardness for your application.
3. PROFILE EDGE
a) Rectangular: applies to 95+ % of flat type printing.
b) “V” shape: applies to 90+ % of cylindrical printing. (Square is also used in some instances.)
c) Ballnose (rounded): used for more ink deposit — generally in some textile printing and industrial specialized heavy deposit applications. However, print edge sharpness is sacrificed. (Also used for direct/indirect stencil making and emulsion reinforcement of capillary film stencils.)
d) Dual-Durometer: used to optimize ink transfer efficiency and squeegee setting (pressure, angle, shear) via decreasing the blade’s susceptibility to bending.
e) Composite: (similar to above) used for maximum rigidity.
