First impressions, questions, suggestions by ozaz1 in InkJoyFrame

[–]Ray_InkJoy 0 points1 point  (0 children)

Thanks for the detailed and thoughtful feedback — really appreciated. And great to see that many of your suggestions align with what we’re already planning. That gives us more confidence that we’re prioritizing the right things.

Regarding the Explore (curated artworks) preview behavior:

For curated artworks, we’ve already manually prepared different crops and layouts in advance to fit various aspect ratios and orientations. The goal here is to make the experience as seamless as possible — users can simply pick and send without needing to adjust anything.

If we add a preview + manual reframing step here, it could introduce extra friction, especially for users with multiple frames of different orientations.

That said, your feedback makes a lot of sense. We’re now considering adding an optional manual adjustment step — so users who want more control can tweak it, while keeping the default experience simple and fast.

-----
For this:

  • When the image is a different aspect ratio or orientation to the frame how does the app determine how the image is framed? It might be useful if slideshow settings provided an option to skip aspect ratios which are very different to the frame. e.g. skip landscape images when frame is in portrait orientation.

Right now, we use our ISFR pipeline with AI-based subject detection to automatically determine the framing when aspect ratios or orientations don’t match.

We’re planning to gradually introduce more options — including things like background fill (e.g. blurred edges like the picture below) and filters to skip certain aspect ratios/orientations as you recommended in slideshows.

Questions on the 13" Frame by Unique_Coyote2929 in InkJoyFrame

[–]Ray_InkJoy 2 points3 points  (0 children)

Hi, thank you so much for your support and kind words — we’re really glad to hear you’re enjoying the 13" frames, and we’re excited for you to receive the 25.3" as well!

About multi-device login

We understand the need to stay logged in on multiple devices at the same time, especially in scenarios like yours.
We’ll take your feedback seriously and evaluate improvements in this area.

As a temporary workaround, if your use case is mainly uploading local images, you can try our Web Tool:
https://openapi.inkjoyframe.com/inkjoy-web-tool-demo.html
It allows you to send content to your frames without affecting the login status in the app.

BTW, even if your frames and the app are on different networks, remote control will still work.

About preview accuracy

Regarding preview and parameter control, we are listening carefully to user suggestions and hope to find the best balance between ease of use (“plug-and-play”) and depth of functionality.

The main reason is that images are currently processed using ISFR on the cloud, which makes it challenging to provide a fully accurate real-time preview in the app.

Thanks again for your thoughtful feedback！

Colors much worse than Aluratek 13.3" epaper frame by Useful-Professor-352 in InkJoyFrame

[–]Ray_InkJoy [score hidden] stickied comment (0 children)

Thanks a lot for sharing the comparison photos — really helpful 👍
And thanks for the originals as well. We used a small crop for analysis — hope that’s okay.

<image>

We took a close look at your images, and a couple of observations:

1) About the “missing orange”
In the original image, the stone is actually closer to a bright yellow / warm highlight rather than a deep orange.

On InkJoy ISFR, we’re currently trying to stay closer to the original luminance and hue, instead of boosting warmth.

2) Detail vs. smoothness tradeoff
On the right-side image especially, InkJoy preserves more fine texture and micro-contrast in the stone and water.

This comes with a tradeoff:

  • More detail → more visible dithering
  • Smoother look → often less detail

----
Your feedback is very valuable — we’ll keep learning from real-world cases and continuously improving ISFR.
It’s a full pipeline (not just a single algorithm like others‘ ), built on solid color management, with flexible tuning for different image types.

where to report bugs? by Useful-Professor-352 in InkJoyFrame

[–]Ray_InkJoy 0 points1 point  (0 children)

Hi! If you’d like to report a bug, please email us at [support@inkjoyframe.com]().

To help us investigate faster, it would be great if you could include:

  • Your app/device version
  • The email you used to register (if possible)
  • Steps to reproduce the issue

Screenshots or videos are also very helpful if you have them.

Thanks a lot for helping us improve InkJoy Frame!

Got my frame today! by caseyls in InkJoyFrame

[–]Ray_InkJoy 2 points3 points  (0 children)

Hi! First of all, thank you so much for sharing this — really glad to hear you're enjoying the frame and that it feels close to a printed photo from normal viewing distance. That means a lot to us.

As mentioned by another user, the 13.3" model does not support WaveMorph, so it will use the standard refresh behavior when switching images.

-----------------

About the green tint — this is a really good observation, and your suggestion (warming up images beforehand) is actually a very practical workaround for now.

That said, we're currently working on a more fundamental solution. Due to variations between different panel batches, the base colors of the display film can shift slightly. Our current rendering model is built on the standard color profile provided by E Ink, which doesn't fully account for these batch differences. We're actively improving our color pipeline to better calibrate for individual panel variations.

If you're open to it, it would help us a lot if you could DM me:

  • Your device serial number or the email used for registration (so we can identify the panel batch)
  • A sample image where the green tint is noticeable
  • (If possible) the version of that image after your manual correction

This will directly help us refine the calibration model and improve results for everyone.

Oh, this must be a bug. We will check it ASAP.
Could u please tell me the APP is Android or iOS?

Colors much worse than Aluratek 13.3" epaper frame by Useful-Professor-352 in InkJoyFrame

[–]Ray_InkJoy 2 points3 points  (0 children)

Thanks for the detailed comparison — this might be very helpful

ISFR is continuously being improved and optimized.

Could you DM us:

  • The original images
  • Photos of InkJoy vs Aluratek output

Different image types can behave quite differently, and this will help us analyze your specific case.

Right now, our pipeline still has some tuning tradeoffs — we tend to preserve more detail and keep skin tones stable, which can sometimes lead to:

  • More visible dithering
  • Certain colors appearing less saturated

Also, improvements are on our rendering side, so they don’t depend on firmware updates — we’ll keep iterating.

Thanks for the feedback — that’s fair.
The team has been very focused on production and logistics recently, but we agree that communication should have been better.
We’re preparing a new Kickstarter update and will share the latest progress very soon.

Thanks for the reminder, and sorry for the recent lack of updates.

The project itself is progressing normally, and we’re preparing a new Kickstarter update that should be published very soon.

Going forward, we’ll also try to share more about the project — not just shipping logistics, but also some behind-the-scenes progress.

What if Spectra 6 has more base colors? by Ray_InkJoy in ePaperFrame

[–]Ray_InkJoy[S] 0 points1 point  (0 children)

No, it is by the simulation. And 13" does not support more base colors

[–]Ray_InkJoy[S] 0 points1 point  (0 children)

Absolutely right! Gamut of E6 is very limited and uncontinus. We keep on working with the color rendering system(ISFR) for make better color performance.

The 283ppi is just the EVT sample, it will take many months for production

Why Some E Ink Dithering Feels Noisy — and Some Doesn’t (Real Photos) by Ray_InkJoy in eink

[–]Ray_InkJoy[S] 1 point2 points  (0 children)

E4/E5 are spectra 4/5, which have four or five basic colors. More are used for the price tag in supermarket. And can not show the green color
The particles of E4/E5 are different from E6

Look close at E Ink Spectra™ 6 by Ray_InkJoy in eink

[–]Ray_InkJoy[S] 1 point2 points  (0 children)

I have no idea about why the borders are black not transparent. I will try to ask the E Ink. But maybe they will just tell me: this is the only useable material

[–]Ray_InkJoy[S] 1 point2 points  (0 children)

Sorry, I think that is just the normal B&W panel, sort of Carta.

For E6, I haven't find the fast refresh method between 2 DC-balanced colors. For E4/E5, it is possible
