By making a surface of the mesh black, it minimizes randon reflection of light during exposure.

It improves emulsion edge resolution.

A stainless surface is covered with a transparent oxide layer which is mainly made of chromium ingredients. The stainless surface can be blackened by growing and controlling the oxide layer per 1/100 micron. By making the surface of the stainless steel wire cloth black, it minimizes random reflection of light during exposure. It is useful when fine pattern image must be exposed and achieves high precision resolution.

※ The oxide layer is extremely thin and the surface is not damaged at all. It differs from paint or plating processing.
