New iPhone colour measuring devices: xade nano+ in test
新款 iPhone 顏色測量設備：xade nano+ 測試中

A new generation of colour measuring devices is entering the market: in contrast to the classic measuring devices, which are available as a fully encapsulated system either as a colourimeter or as a spectrophotometer, and then supply the data to a computer via an interface or app or display it directly, the new generation of colour measuring devices consist only of lighting and software, with the optics of a modern iPhone from Apple being used as the sensor.
一種新一代的顏色測量設備正在進入市場：與經典的測量設備相比，這些設備作為全封閉系統可用作顏色計或分光光度計，然後通過接口或應用程序將數據提供給計算機或直接顯示，這新一代的顏色測量設備僅由照明和軟件組成，並使用蘋果公司現代 iPhone 的光學作為傳感器。

Until now, there have been two categories of measuring devices on the market: on the one hand, precision devices, i.e. spectrophotometers from the industry giants such as X-Rite or KonicaMinolta, and on the other, inexpensive colourimeters or spectral measuring devices such as the NCS Colorpin or the ColorReader from Datacolor, the Colormunki from X-Rite, the NIX measuring devices, which are also available in a spectral version, or the ColorCatch Nano 2.
直到現在，市場上有兩類測量設備：一方面是精密設備，即來自行業巨頭如 X-Rite 或 KonicaMinolta 的分光光度計；另一方面是廉價的色度計或光譜測量設備，如 NCS Colorpin 或 Datacolor 的 ColorReader、X-Rite 的 Colormunki、NIX 測量設備（也有光譜版本）或 ColorCatch Nano 2。

The new iPhone devices are divided into two categories: Firstly, there are devices such as the Colorgrail from France, which classifies itself as a spectrophotometer, and secondly, extended colourimeters such as the xade nano or the xade nano+ from Germany, which is a spectrally extended colourimeter. The colorgrail emits light onto the measuring field through spectrally fanned light sources, then measures the reflection and combines these photos into a spectrum and a measured value.
新的 iPhone 設備分為兩類：首先，有來自法國的 Colorgrail 設備，自我分類為分光光度計；其次，來自德國的擴展色度計，如 xade nano 或 xade nano+，這是一種光譜擴展色度計。Colorgrail 通過光譜擴展的光源將光線發射到測量區域，然後測量反射並將這些照片合併成光譜和測量值。
The xade nano+ has four white LED light sources with a high RI of 97 mounted in the housing, illuminating the measuring field and eliminating stray light from the outside thanks to its design.
xade nano+ 擁有四個高 RI 達 97 的白色 LED 光源，安裝在外殼內，照亮測量區域並由於其設計消除來自外部的雜散光。
Both devices compete with traditional spectrophotometers, and as we already have an NCS Colourpin SE, it made sense to test the new xade nano+ against an i1Pro2 and the NCS Colourpin SE.
這兩款設備與傳統的分光光度計競爭，因為我們已經擁有一台 NCS Colourpin SE，因此測試新的 xade nano+ 與 i1Pro2 和 NCS Colourpin SE 之間的表現是有意義的。

The xade nano+ is simply plugged onto an iPhone 14 Pro or 15 Pro and supplied with power via the Lightning or USB-C port.
xade nano+ 只需插入 iPhone 14 Pro 或 15 Pro，並通過 Lightning 或 USB-C 端口供電。
As it has a direct cable connection with the iPhone, it requires neither an external power source nor a battery, so measurements can be taken anywhere without an additional notebook.
由於它與 iPhone 之間有直接的電纜連接，因此不需要外部電源或電池，因此可以在任何地方進行測量，而無需額外的筆記本。
It is simply attached to the photo optics of the iPhone Pro and connects magnetically to the iPhone. All functions can be conveniently controlled via an app.
它簡單地附加在 iPhone Pro 的攝影光學上，並通過磁性連接到 iPhone。所有功能都可以通過應用程式方便地控制。

To compare the measuring devices, we measured 5 PANTONE base colours and 7 PANTONE pastel base colours in order to have both saturated and unsaturated tones for comparison. Measurements were taken in D50 2° M2 in each case, although the NCS Colourpin SE does not provide any information on lighting, but an M2 seems plausible.
為了比較測量設備，我們測量了 5 種 PANTONE 基本顏色和 7 種 PANTONE 粉彩基本顏色，以便擁有飽和和不飽和的色調進行比較。每種情況下的測量均在 D50 2° M2 下進行，儘管 NCS Colourpin SE 並未提供任何有關照明的信息，但 M2 似乎是合理的。

It goes without saying that the operation of app-controlled measuring devices such as the xade nano+ and the Colourpin SE with the Colourpin app is simple and convenient.
不言而喻，使用 xade nano+ 和 Colourpin SE 以及 Colourpin 應用程式的應用程式控制測量設備的操作簡單方便。
However, the xade nano+ showed its best side in the colour deviations compared to a measurement with an X-Rite i1Pro2.
然而，xade nano+ 在顏色偏差方面顯示出其最佳表現，與使用 X-Rite i1Pro2 的測量相比。
On average, the colour deviations of Ø-DeltaE00 were only 1.34 compared to the X-Rite device; with the similarly priced Colourpin SE, these values were more than three times as high at Ø-DeltaE00 4.25. This shows how well the new smartphone optics of the mobile phones match each other and how well they can be controlled and read out with new lighting and software.
平均而言，Ø-DeltaE00 的顏色偏差僅為 1.34，相較於 X-Rite 設備；而與同價位的 Colourpin SE 相比，這些數值超過三倍，達到 Ø-DeltaE00 4.25。這顯示出新款手機的光學系統之間的匹配程度，以及它們在新照明和軟體下的控制和讀取能力。

With a simple click on the Measure button, the colour fan is measured and is available as a measurement a few seconds later. The measured values for D50 can then be read in the spectral view.
只需輕按測量按鈕，顏色扇形便會被測量，幾秒鐘後即可獲得測量結果。然後可以在光譜視圖中讀取 D50 的測量值。

Selection of the measured variable
測量變數的選擇

A particularly impressive feature of the xade nano+ is that the size of the measuring aperture can be flexibly defined. This means that either a large colour range can be captured or, with the smallest measuring aperture on the right, only the black text of the PANTONE text under the fields of the colour fan can be included in the measurement.
xade nano+ 的一個特別令人印象深刻的特點是測量孔的大小可以靈活定義。這意味著可以捕捉到較大的顏色範圍，或者在右側使用最小的測量孔時，只能將顏色扇形下方的 PANTONE 文本的黑色文本納入測量。

Measuring optics  測量光學

The top of the xade nano+ is an illumination unit with 4 integrated LEDs and a white plate on which coloured dots are presumably attached to calibrate the xade nano+.
xade nano+ 的頂部是一個照明單元，配備 4 顆集成 LED 和一個白色板，上面顯然附有彩色點以校準 xade nano+。

Microscope function  顯微鏡功能

For me, the new optics of the current iPhone Pro generations are an absolute phenomenon. The xade nano+ can also be used for magnification, for example, and is able to reach zoom ranges and resolutions that were previously only possible with a small microscope.
對我來說，目前 iPhone Pro 代的全新光學技術是一個絕對的現象。xade nano+ 也可以用於放大，例如，並且能夠達到以前只有小型顯微鏡才能實現的變焦範圍和解析度。
This can also be a useful application in everyday printing, allowing you to quickly zoom in on a raster or an increase in line thickness.
這在日常印刷中也可以是一個有用的應用，讓您能夠快速放大光柵或增加線條粗細。

Batch measurement and scan measurement
批量測量和掃描測量

Not so exciting for us, but certainly very useful for some users: the xade nano+ also has a batch mode that allows you to take numerous measurements in succession without having to wait for the result; the app processes and saves the measurements in the background, which can then either be viewed or exported as json.
對我們來說並不是那麼令人興奮，但對某些用戶來說肯定非常有用：xade nano+ 還具有批量模式，允許您連續進行多次測量，而無需等待結果；應用程式在背景中處理並保存測量結果，然後可以查看或導出為 json 格式。
In scan mode, the nano+ captures the surface over which it is moved for five seconds after a tap on the screen. This is helpful for unstructured surfaces in order to obtain a good average value.
在掃描模式下，nano+ 在觸碰螢幕後會捕捉其移動表面五秒鐘。這對於不規則表面來說非常有幫助，以獲得良好的平均值。

Conclusion  結論

The xade nano+ was a real surprise for us, as the colour measurement values were very close to the much more expensive i1Pro2. Even in dark and saturated areas, the measurements were surprisingly accurate to those of the i1Pro2 and significantly better than the comparably priced competitor from NCS.
xade nano+ 讓我們感到驚訝，因為其顏色測量值與價格昂貴的 i1Pro2 非常接近。即使在黑暗和飽和的區域，測量結果也出乎意料地準確，與 i1Pro2 相比，顯著優於 NCS 的同價位競爭對手。
As both the device and the software app are still under constant development, it will be interesting to see what further ideas and functional enhancements xade can come up with.
由於設備和軟體應用程式仍在不斷開發中，期待看到 xade 能提出哪些進一步的想法和功能增強。
