| V-SCREEN is woven with Thermotropic Liquid Crystal Polyarylate thread named VECRY. This super thread VECRY was originally derived from multifilament thread used for the airbag system of the MARS PATHFINDER spaceship and it converted into monofilament thread suitable for screen printing mesh. |
|
| VECRY is hybrid fiber composed of a sheath and core. The sheath has an "island-in-a-sea" structure and is shown in the below. |
 |
| Construction model of hybrid thread |
|
 |
High strength with low elongation |
 |
Highest recovery elasticity |
 |

The diagram shows the tension loss after stretching from 2 - 14 days. V-SCREEN can be stretched to an extremely high tension level because of its superior tensile strength, which minimizes off-contact distance. |
 |
| The diagram shows the excellent stability of V-SCREEN from 500 to 5,000 prints. Minimal distortion enables you to obtain the most consistent results even after long printing runs. |

| The magnified pictures show the difference of resolution between V-SCREEN and stainless steel wire mesh, and on the squeegee side of the emulsion. The thread transparency, emulsions/stencil films can be properly exposed through V-SCREEN, which improves stencil quality and printing definition compared with stainless steel wire mesh. |
