Different aspects of the service

A one-stop ink discharge evaluation service
  • An ink discharge evaluation service to bring inkjet printing to a wider range of applications.
  • From receiving the ink to running ink discharge tests and writing reports, Elephantech provides a one-stop service.
Ink evaluation using a cutting edge Inkjet machine for R&D
  • Using Epson's PrecisionCore inkhead, performance indicators for printing onto substrates and such are evaluated with inkjet printing equipment used for cutting edge R&D.
  • If necessary, we will also perform waveform adjustments and Print Evaluation.
Conditions regarding the evaluation
  • This service is provided by Elephantech under license from Epson. The evaluation results will be shared with Epson.
  • In general we offer an initial ink discharge evaluation service free of charge. There may be cases where we cannot progress to the evaluation following a safety data sheet (SDS) check.

Results provided by the ink discharge evaluation service

Test items Description of items

Initial ink filling

We will evaluate the initial fill characteristics on an inkjet nozzle, mainly focusing characteristics as a fluid.

Intermittent stability

We will evaluate the stability in situations where ink is discharged intermittently. We will mainly judge ink discharge stability and resistance to drying.

Droplet volume followability

We will evaluate whether the volume of the droplet follows changes in voltage. Higher followability will allow for finer control.

Drop velocity followability

We will evaluate whether the drop velocity follows changes in voltage. High-speed flight will stabilize the landing position and allow for high-precision printing.

Frequency characteristics

We will evaluate suitability for high-frequency printing. We will determine how far the printing throughput can be increased to.


What is the relationship between Elephantech and Epson?

Epson is a shareholder of Elephantech and we have a capital and business alliance. (We are not an equity method affiliate.)

What is the relationship between Elephantech and Epson regarding the ink discharge evaluation service using Epson’s Inkjet machine for R&D?

Epson has set up a research and development base called “Inkjet Innovation Lab Hatchobori Satellite” inside the Elephantech Hatchobori Head Office, and Elephantech is entrusted by Epson to conduct research and development work such as ink evaluation.

The Inkjet machine for R&D at Hatchobori Satellite is an Epson R&D asset.

Can the ink discharge evaluation be done without having the results shared with Epson?

We regret to inform you that the ink evaluation is done using Epson assets, and so the R&D inkjet printing device cannot be used to evaluate the ink discharge without the results being shared with Epson.

Can we ask Epson directly for an evaluation?
It will depend on the resources at Epson's disposal, but it is possible. There is no specific need to go through us.
