Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a color chart for controlling the quality of dried leaf tobacco.

More details on the drying process of fresh tobacco leaves! Buried.

Inspecting the quality of dried tobacco leaves, managing changes over time during storage, inspecting and managing various abnormalities such as damage caused by various pests and diseases, discoloration due to decompressants, genetic causes, etc. The quality grading is related to the color chart used for various management of dried leaf tobacco.

The first requirement for a color chart used for quality control of dried tobacco leaves is that its spectral characteristics be similar to the color of dried tobacco leaves.

However, simply because the spectral characteristics are similar, the measurer cannot accurately compare the colors between the color chart and the dried leaf tobacco.

This is 1! j. The color of the dried leaves cannot be expressed as a single color, and the color is one hue.2. This is because there are a lot of bugs.

Therefore, for example, color photography can be used to obtain a color chart that faithfully reproduces the hue unevenness and RS concealment unevenness of the harmful dried leaf tobacco, but even if colors are faithfully reproduced by the cuff photography method, .

In practice, t1 is not necessarily sufficient to achieve ratio 81. This is because the surface of dried leaf tobacco has unevenness.
This is because there is an S-part light scattering property.

The present invention has been made in light of the above-mentioned problems, and its object is to provide a color chart for managing dried leaf tobacco that makes it possible to measure the degree of Aff in the colorimetric determination of dried leaf tobacco.
ru.

Another object of the present invention is the accuracy (1″
A highly durable dry leaf tobacco e-color chart that not only tastes great but also prevents fading and discoloration over time. It is to provide the foundation.

The above-mentioned object of the present invention is to provide a color chart for controlling dried leaf tobacco with a custom-made t-μ whose surface approximates the light scattering properties of dried leaf tobacco.
This can be achieved by applying a weathering treatment and placing a weather-resistant substance inside the color chart and/or in the protective layer on its surface.

The present invention will now be described in detail.

First, a method for creating a color patch according to the present invention using a color photographic method will be explained.

A standard sample of dried leaf tobacco is used for each purpose (for example, for quality grading).

In general, dry tobacco has wrinkles, tears, etc., and is not suitable for taking photographs for color charts if left as is. Therefore, in advance, smooth out the wrinkles on the first layer, repair the torn parts, and paste it evenly over the entire surface on a flat board (Island color is good). Next, the dried leaf tobacco prepared as described above is photographed in color. What must be noted here is that the photographing conditions must be selected to emphasize color reproducibility and to avoid color shift (color shift between celestial objects and the reproduced object) due to color photography. To do this, the light source characteristics, lighting conditions, etc. at the time of shooting must be taken into consideration.

A color chart (photograph) is created by photo printing after the photo is taken, and the printing method may be the negative-positive method or the bright-positive method, as long as faithful color reproduction can be achieved. The color patch prepared by the color photographic method is processed so that its surface has light scattering properties similar to those of dried wolfberry. As this surface treatment method: 1. This can be done by various methods as described below.

Use a replica method such as @ S U M P using a microscope, or make a peeled aftertaste mold by pressing dried leaves on clay or plaster, and make a peeled aftertaste mold, and in the female mold,
A transparent film having the same surface shape as the four sides of dried leaf tobacco can be obtained by pouring a transparent resin dissolved in ffi in a modest solvent, or a transparent glass material melted by heating. The surface of the thus prepared film has the same surface shape as the surface of dried leaf tobacco, and the actual image (smooth surface) is pasted onto the image surface of the color patch previously obtained by color photography.

Figure 1 and Figure 1 are a cross-sectional view and an enlarged surface view of the color chart prepared in this way, respectively.

In the figure, l is a nine-color print made by color photography, in this case using photographic paper. λ is a transparent film with the same surface shape as the surface of dried leaf tobacco. 3 is a thick vein, and Hiro is a thin 'S vein.

Examples of transparent resins that are dissolved in organic solvents include triacetylcellulose and nitrocellulose, which are used as photographic film materials.

Furthermore, polycarbonate resin and the like are preferred. In addition, examples of transparent plastics used in heat melting [7] include polyethylene/, polyvinyl chloride, polystyrene, AB
S I acrylonitrile, butadiene, styrene copolymer) resins, etc. are preferred.

There are other methods of surface treatment (7) In photography, there is also a method of approximating the light scattering characteristics of the surface by the air mat solution used. As a result, Fuji Photo Film Co., Ltd. completed production.
By spraying on Manodo Dt8*, it was possible to obtain round physical properties that approximated the light scattering properties of dried leaf tobacco. The main composition of Air Mat D is shown below.

Next, a method of imparting weather resistance to the color patch will be explained.

In the present invention, weather resistance specifically refers to light durability under an evaluation light source, durability against high temperature and high humidity environments, and the like.

Useful methods for imparting weather resistance include ultraviolet absorbers and/or antioxidants [one or more kinds].

Within the color chart material itself and/or its! ! There is a method of adding it to the surface protective layer. In other words, when making a brown prefecture using the method described above, it is possible to use a female mold with the surface shape of dried leaf tobacco. When pouring a transparent resin dissolved in an I-containing agent or a transparent plastic that has been heated, UV W4 is applied at the same time.
@, 71D is added to the collecting agent and/or antioxidant 1. Alternatively, in a method in which air mat liquid is used for toilet use, it may be added to the liquid.
