Customer Reviews
The product and the service was excelent. it came to colombia without many problems (just aduana problems)..supplier 100% recomenmed

—— Eider Granada

Everything was delivered in perfect condition. After assembly, I confirmed operation. Thank you for this product.

—— Josiah Hall

Everything went as expected and the product arrived in good condition. 3NH is a good supplier and I will definitely use them in the future.

—— Mihai Paunescu

T60 (5) color Light Box - 600 mm -5 lights It seems the same like the image

—— Penney Ubieta

good performance and will buy another one soon.

—— Stuart Serchuk

Medidor de brillo es hermoso

—— Mauritius Telecom

I got model HG60 gloss meter. it is good to test the gloss on our metal product after powder coating. thanks a lot

—— Cliff Lai

Standard Color Viewer Transmission Light Box, Type: HC5100/HC3100 I got this light box, and it worked very well like DNP light box. I will use it for our transparent test charts often.

—— Klaus Kohl

Good morning^^ Thank you for your product. Thank you for sending me a good product. Have a great day today.

—— Kim Hee-jung

We have received the machine in good condition.(NR110 , T60(4))

—— Woot Usanachitt

The 2 equipment NS810 spectrophotometer and T60+ light box works fine. I will contact you when i need assistance.

—— Patrick Unifine

Thank you for your email and the superb service you provide for model NR145 COLORIMETER. Everything is working fine, like expected. For now we do not need a gloss meter. But, I will keep it in mind for future experiments and recommend you to other collegues.

—— Kristof Holsteens

hi Melorae it is working fine. thank you regards Chia

—— Chia

We have got YS3060 spectrometer and it works fine

—— Ruslanas Fadiuškinas

We are trying the colorimeter NR110 and the results are so good at the moment. Now, we are looking for another colorimeter with 45º method. We would like this colorimeter is portable and as complete as you can because it will be for lab trials.

—— Judith Sánchez

Hi Melorae Sure, everything is fine, we are preparing a good test environment for production to check the quality of the assembled products. The chart is fundamental!

—— Max Massimiliano Marchionni

Looks good thank you

—— Duane Eigbrett

The Sales Manager - Melorae Huang was very responsive and accommodating. I am very satisfied with the support she provided. The ns800 spectrophotometer, so far, seems to work well for the skin color measurement application. The software enabling the instrument to communicate with computer could be much better and the manual could be more detailed.

—— Carlos Tekax

I am very satisfied with the product NHG268 gloss meter and the delivery. Got it in less than a week. Works as it should and seems like high quality. Recommed it ❤️

—— Ariman Omar

Hi Just to let you know. We got the light box! :) Thank you!

—— Nyla Burgos

Have a nice day to you :) Dear Ms. Melorae, we have learned to determine the values ​​of L*A*B and CMYK. We actively use a spectrodensitometer, this device helps us a lot in our work. But we have a question.

—— Anastasia

Hi there Ms. Melorae Huang, we already got the spectophotometer. Is still in the box since our government took the decision of suspend the non essential activities due the novel coronavirus to prevent the spread of the disease, among anothers measures. We will be in lockdown till march 31th. So as soon as we tested we will inform you.

—— Melvin

Dear Melorae, Well received. Thank you! Best regards, Eva

—— Eva

Dear Meloare, Thanks for your message. The light box T60+ is working fine. No need for more at this stage, I will contact you in case of needs With best regards Joel

—— Joel

Long time from our las message. The ns820 device works properly and the client is resonably happy with it. There are some aspects in the software that they will prefer to be a little bit different but I found some workarounds when it was the case. Kind regards, Mihai

—— Mihai

The unit NH310 colorimeter works well.

—— Ivan Khor (Mr.)

Many thanks for your concerned, I am working pleasant with your NHG268 Again,

What is the meaning of Color Density and CMYK?

What is the meaning of Color Density and CMYK?
What is the meaning of Color Density and CMYK?
 
First of all, let's understand the density. To be precise, it's the color density. The density represents the ink's ability to absorb light. For printing three primary colors CMY, the thicker the ink layer is, the stronger the ink's ability to absorb light is, and the higher the density value is (the density will hardly change as the ink layer thickness increases to a certain extent).
 
What's the standard of density? Sometimes we often hear that the C / M is 1.45-1.55, y1.05-1.1, k1.75-1.85. Are these standards?
 
After all, the control of density value is for better color reproduction, matte, bright tone, level and so on. That is to say, we control the density is actually to control the color. For the control of color, there is an international standard iso 12647-2 for offset lithography, in which iso 12647-2 specifies the TVI under a certain state (surface type, printing process) CIE l * a * b * value. If these standards specified in ISO are met, then record the CMYK four-color density value, then this is the standard density of this printing machine. (if the state of multiple presses is basically the same, these standard densities will not fluctuate too much.)
 
This function is the measure of the ink thickness. For the process colors Cyan, Yellow, Magenta, or Black the desired Density Status (A, E, I, T) needs to be configured. For spot inks the result is given as the density value at the wavelength of maximum density for the spectral curve. This function can be optionally configured to subtract the white base/substrate.
 
There are four Measurement Conditions for density.
 
1. M0 (No) – No Filters
 
Reflectance measured with A Illuminant, previously called: No-Filter, UV-Included.
 
2. M1(D50)
 
Reflectance measured with D50 Illuminant previously called: Daylight or D65-Filter.
 
3. M2(UVC) – UV Cut Filter
 
Reflectance measured with A Illuminant excluding UV component, previously called: UV Cutoff Filter, UV excluded.
 
4. M3(Pol) – Polarization Filter
 
Reflectance measured with cross-polarized A Illuminant excluding UV component, previously called: Polarization-Filter.
 
Here is ISO Status T, E, A, I d
 
1. Status A is applicable to the measurement of color sensitive materials;
 
2. Status E is widely used in the measurement of printed matter and materials in Europe,
 
3. Status I is used to evaluate printed board materials,
 
4. Status T is applicable to the measurement of color separation printing and printing materials such as paper printing and offset printing.
 
T-Status density is defined as the response that best matches the original art film used to evaluate color separation in history.
 
Generally, the default state in China is T status.
 
3nh launched two models spectrodensitometer YD5050 and YD5010. YD5050 density meter is to compare with Xrite exact advance spectrophotometer while YD5010 spectrodensitometer is to compare with Xrite exact basic model.
