See the difference.

APHEUM Deep-Grayscale creates the appearance of 255 grayscale levels – instead of 16 with standard E-Ink.

We developed "digital printing" on APHEUM paper. While conventional e-paper displays are limited to 16 shades of gray, our deep grayscale algorithms create the appearance of 255 shades of gray.

The problem with standard E-Ink technologies.

Conventional e-ink technology is brilliant for text, but often disappointing for art. A closer look reveals its digital origin: reduced grayscale, harsh tonal shifts, and a lack of depth.

We were impressed by the quality of APHEUM's frames, which successfully capture the essence of classic prints while simultaneously utilizing the possibilities of digital visual art.

The solution: APHEUM Deep-Grayscale.

We developed "digital printing" on APHEUM Paper. While conventional e-paper displays are limited to 16 shades of gray, our deep grayscale algorithms create the appearance of 255 shades of gray.

The result.

Not a raster image, but an organic gradient. Our technology imitates the grain of a silver gelatin print. It doesn't glow – it reflects. The image isn't simply displayed: it's physically recreated. Every time.

I saw a frame with a great black and white print.

Nothing unusual – or so it seemed.
Then Christopher took his mobile phone out of his pocket and tapped a button.

At that moment, the image in the frame changed – a new, equally outstanding photograph appeared.

I could hardly believe it.

I was blown away!
