Seiko Advance is a company that creates ink for devices like the iPhone. Cook was shown a vat of the Midnight Green dye when he visited Seiko Advance, and said that it was āonly made by high-quality control and craftsmanship.ā
Creating green ink typically involves using pollutants like halogens, but according to Seiko Advance sales manager Yukinori Kabe, the company was able to develop a cleaner way to create green with high color accuracy and durability. Seiko Advance is also the only ink producer with a cleanroom in the factory, allowing temperature and humidity to be controlled for consistent quality.
The environmental friendliness of Seiko Advanceās green ink appealed to Apple CEO āTim Cookā, leading Apple to add the color to its 2019 āiPhoneā lineup. Seiko Advance is also the sole supplier for the Gold, Silver, and Space Gray inks used for the āiPhone 11 Proā and Pro Max.
For the lower-priced iPhone 11, which comes in multiple bright colors, Apple uses several suppliers.
Cook in his tweet about Seiko Advance said the company brings the colors of the āiPhone 11 Proā to life thanks to ātheir craftsmanship and attention to detail.ā Apple has worked with Seiko Advance for āiPhoneā inks since 2011, when Cook invited various ink makers to visit Apple to explain their products.
Kabe visited Appleās campus in Cupertino, met Cook for the first time, and found that at first, Seiko Advance wasnāt able to meet Appleās high quality standards. Four years later, after trial and error, Seiko Advance supplied black ink for the āiPhoneā, leading to a partnership that now accounts for 40 percent of Seiko Advanceās sales.
According to Cook, Apple and Seiko Advance have āgrown togetherā and āpush each other to innovate more.ā
