With the availability of the E Ink Gallery 3 screen, though, we're hoping this will change and that the next e-ink device to join our best ereader round-up would be a color Kindle or Kobo. Here's hoping. The reader works with the Android system and has been available only in small numbers in Asia. iFlytek Reader color

The iReader color reader, "iReader C6" (for "C" color and "6" 6 inches diagonal) is the first to be released. Create colour palettes for each project or even individual rooms by saving each capture with a unique reference to the job or room. Several captures may then by organised and accessed together to build the colour palette. If the rendering is not up to the level of an e-ink screen, this machine is interesting for comic book lovers.Depending on the application, a suitable design is also to be selected in the sense of ergonomics. In some devices, the display is placed on the top, while in the other color meters the data is read from the front side and the sensor system is internally installed in a housing. Besides, there are also measuring instruments with external sensors. In addition, some measuring instruments have built-in cameras to assist in the positioning of the measuring device on the object to be measured. Particularly for small objects and small apertures, this function helps to choose the correct positioning of the device, and thus, “hit” the measuring point. This year marks a real renewal in terms of color readers since the democratization of the new technologies of color screen Kaleido 3 and Gallery 3.

The big advantage of this e-reader is the Android 12 system, which enables new applications to be installed. di (8° illumination angle/diffuse viewing, specular component included (SCI); DIN5033 Teil7, JIS Z 8722 condition d, ISO7724/1, CIE No.15、ASTM E 1164) Color meter works according to the tristimulus absorption and imitates human vision. In the human eye the three basic colors red, green and blue are recorded over three different cone types, color meter imitates this color perception by means of 3 color sensors with almost identical spectral sensitivity in the areas of red, green and blue. The color values determined in this way are represented as X, Y and Z values on the display by the measuring devices, the conversion into common color spaces such as CIELab or RGB is carried out by most devices automatically. It is a rather classic color reader with a 6 inch touch screen that allows a display of up to 4096 different colors on the screen.

On the other hand, there is Wacom, which specializes in pressure-sensitive touch pens and other input devices. Comparison problem: Semi-finished products are measured with color meter A and sent out to a processor company which produces the end product. In the processors company the incoming products are measured by color meter B. The result is different to the data measured with the meter A. That means the color meters used in the production chain should be from the same type, adjusted and calibrated in the same laboratory to reach nearly the same measurement results. So complaints can be avoided in the most of the cases. It is not an ideal solution, but both parties can talk about precisely defined differences in chromaticity, because they have set the color space before and use in the same color meters.
