High- AccuracyDigital Separation of Mesh Paste

What sets screen printing apart from other types of stencil printing is its most special feature– that paste is distributed evenly along and through the mesh. 
If we define analog as not being able to represent something in numbers, and digital as being able to, then we can consider paste, which in screen printing is transferred from the mesh of the screen mask, as digitalized.

Digitalization by Mesh

Digital vs. Analog Mechanisms of Paste

In a nutshell, screen printing is the process of:
❶Taking the analog paste on the screen mask,
❷Digitalizing the pattern through the mesh openings,
❸And returning it to an analog pattern on the substrate.

Essential to High Density Digitalization of High Quality Printing

Just as digital broadcasts have improved step by step to high density 4K and 8K, screen printing quality would also improve if the digitalization of screen printing with high density paste can be achieved. The finer the screen mesh, the better the print resolution. This makes high density digitalization possible.
When printed line width is more than two times the mesh pitch, the paste can be digitalized to be more than fine enough, keeping printing stable.
When printed line width is less than mesh pitch, the paste cannot be digitalized to a fine degree, therefore to increase print resolution an optimally viscoelastic paste is necessary.

* Difficulty printing varies greatly depending on the type of substrate (ex. water absorbent, hygroscopic, etc.).
