Screen Mask Technical Information
For fine pattern printing
High-density meshes such as ST640 and ST500 are combined with high-resolution emulsions to support fine-pattern printing, such as fidelity of 15-μm lines. (Under 10μm also under development)
Main applications
Printing on ceramic green sheets for touch panel wiring, inductors, solar cell finger electrodes, and high frequency components
For thin film printing
Excellent surface smoothness prevents deterioration of printability when using thin emulsions. Supports emulsion thickness up to 0 µm* The mesh and emulsion thickness can be suppressed, enabling thinner printing and reduced saddling.
Main applications
Thin-film laminate printing of capacitors, etc.
[Print comparison]
For thick film printing
Stable tension and film thickness ensure high quality printing.
Main applications
Printing of sealing resins, adhesives, etc.
Initial dimensional durability and high durability plate making
We offer specifications with excellent initial dimensional accuracy and durability by combining high-tensile strength stainless steel mesh and various optional treatments and processing.
The achievable accuracy varies depending on the stencil, material, and options used, so please contact us first.
Main applications
Thin-film laminate printing of capacitors, etc.
Special Combination
Support reinforcement
- The support section of the combination is reinforced with a special film.
- This contributes to dimensional stability.
Corner radius
- R-shaped corners of the main mesh reduce damage during printing.
※License No.3462125
Polygonal combination
- Pentagonal or larger combinations (irregularly shaped combinations) can reduce material costs.
Water and oil repellent treatment
Fluorine is applied to the surface of the emulsion to impart water and oil repellency.
Flat treatment
Prevents undulation of the emulsion surface caused by the mesh.
(This is especially effective when the emulsion thickness is thin.)
Inhibition pattern
This plate-making process is designed to meet the demand for printing as thinly as possible. The amount of paste dispensed can be controlled by creating a mesh or other inhibition pattern with the emulsion. It is also effective in reducing saddling.
High-precision dimensions & thickness
A pitch dimension of ±5μm and in-plane thickness of ±0.5μm are achieved by setting and regulating special treatment conditions. We will continue to pursue high-precision plate making, so please contact us if you have any unsolved issues around accuracy.

SPC plate (mortar method)
SPC plates are made using a process that improves paste ejection by widening the aperture on the squeegee side more than on the emulsion side.

Advantages of SPC plates
The higher resolution limit in plate making improves paste passability. ※L/S＝20/20μm
Please contact us for information on the plate-making and printing accuracy of our SPC plates.
We will continue to optimize plate-making conditions in order to support even higher definition printing.
Stepped screens
By creating height differences on the plate surface, printing on uneven substrates is possible.
