Ultra-high-definition Negative Films

Based on over 40 years of experience in special printing,
we produce large-sized high-precision negative films with one of the world’s largest laser drawing machines.
High-precision negative films are essential for LCD panel, semiconductor, and integrated circuit manufacturing, and can be efficiently used in large sizes.

Major applications

01

Masks for screen printing plates

Dimensional accuracy: Total pitch ± 100 μm
Compared to outputting on each small negative film and connecting them together, outputting in batches on a single large-sized negative film has the advantage of not only improving accuracy but also significantly reducing man-hours.

  • TAC film for coating polarizing plates, which make up liquid crystal panelsTAC film for coating polarizing plates, which make up liquid crystal panels
  • Much fewer man-hours and processes, and higher accuracyMuch fewer man-hours and processes, and higher accuracy

Our negative films have been used for many applications, including the coating of polarizing plates, which make up liquid crystal panels.

02

Negative films for touch sensor wiring

Dimensional accuracy: Sensors 5 μm, Traces 15–20 μm
Film masks are attracting attention because they are inexpensive compared to glass masks, which are very expensive.

  • Exposure masks for touch sensor wiring for smartphones, tablets, and other devicesExposure masks for touch sensor wiring for smartphones, tablets, and other devices
  • Contribute to significant cost reduction

Our conductive silver mesh films have been used for many applications, including automotive touch screens.

03

Negative films for metal etching and etching on photomasks for exposure

Our negative films support the resolution that corresponds to the common minimum line width of several hundred micrometers.

  • Negative films for metal etching and etching on photomasks for exposure image１
  • Negative films for metal etching and etching on photomasks for exposure image２

Flexible, lightweight, and easy-to-handle film masks for PWBs, FPCs, electronic components, graphics, and more
