In addition to the quality of the product itself, the beautiful and gorgeous packaging is absolutely attractive. So how to control the color of the outer packaging? The hand-held color difference instrument of CHNSpec is needed to solve the problem. The hand-held color difference instrument is used to digitally manage the color of outer packaging, which eliminates the error of human eyes; The hand-held color difference meter can also record the packaging color and call it at any time.

Mask is a carrier of beauty care products and a category of skin care products. The basic purpose is to make up for the lack of cleaning and cleansing. On the basis of this, we cooperate with other essential ingredients to achieve other maintenance functions.
As women's friends pay more and more attention to skin care and maintenance, mask sales are very hot. Not only advertisements are played every day, but even big circle of friends can't escape.

Next, we use CS-580 handheld color difference meter for experimental measurement.

The CS-580 handheld color difference instrument adopts professional horizontal design without any moving parts, which avoids the shaking of the instrument during handheld operation and makes the test more accurate; USB transmits data and PC software operates on the upper computer, making your color control more free; Large storage space: it can store 100 groups of standard samples, with a maximum of 200 test records under each group of standard samples; SCI and SCE can be measured at the same time, and SCI / SCE data can be displayed through LCD panel.

The following are the specific measurement steps:
Step one: first prepare the mask packaging bags to be tested (Figure 3).

Step 2: turn on the CS-580 handheld color difference meter and conduct black-and-white calibration (as shown in Figure 4);

Figure 4 black and white calibration

Step three: after black-and-white calibration, press the "Cancel" button to exit, then place the sample, press the "Print" button, first locate the measuring area by image, place the standard sample of the envelope to the test hole, press the "Test" button, and complete the measurement after "dropping", then check the test results.
Step 4: after the standard sample measurement is completed, press the "menu" key to enter the "sample measurement" interface under the standard sample. Align the sample with the test hole according to the standard sample measurement method, press the "test" key for measurement, and complete the color difference measurement after "dripping" sound to obtain the measurement result.

Step 5: after the sample measurement is completed, click the "enter" key and select the spectral reflectance to see the reflection spectrum of the measured color, and then the color matching personnel can adjust the color according to the comparison of the reflection spectrum of the standard sample and the measured color of the sample.

Fig. 7 Comparison between standard sample and sample

Generally speaking, the reflection spectrum seen by human eyes is 400-700nm, and the red light is 615-650nm; Orange: 600-610nm; Yellow: 580-595nm; Yellow green: 565-575nm; Green: 495-530nm; Blue light: 450-480nm; Purple: 370-410nm; White light: 450-465nm (but the color of light is not specific, this is only a range. After all, there is no completely single color in the world). People can adjust the color matching formula in time according to the spectral reflectance.

Using hand held colorimeter to control the color of mask packaging is simple. This kind of handheld color difference meter has strong endurance, relatively small fuselage, easy to carry, and high accuracy. This handheld color difference meter has powerful functions.
