Ultraviolet fluorescent anti – counterfeiting ink use instructions

Ultraviolet fluorescence anti – counterfeiting ink into long, short – wave fluorescence. Long – wave fluorescent ink invisible colorless or colored two. The former is usually white or colorless, printed on paper or plastic film does not show color, under ultraviolet light or detector different varieties will show different colors, red, yellow, green, blue and other different types.

I. performance introduction
Ultraviolet fluorescence anti – counterfeiting ink into long, short – wave fluorescence. Long – wave fluorescent ink invisible colorless or colored two. The former is usually white or colorless, printed on paper or plastic film does not show color, under ultraviolet light or detector different varieties will show different colors, red, yellow, green, blue and other different types. It is suitable for security protection of negotiable securities, certificates, official documents and all kinds of high-end tobacco, wine, drugs, cosmetics and other famous products. And colored fluorescent security ink in the detector or ultraviolet light to show the same color as the original color of the ink, mainly used for bills or other security needs of printing, there are different colors for users to choose. Short wave security ink, this kind of ink in the short wave lamp fluorescence response, this technology has been used on the bank check behind the two-dimensional code, also can be used on the bills, signs

Fluorescent security inks are divided into gravure, silk screen, offset, UV offset, UV embossing, waterborne flexo, suitable for different needs of the printing.

Ⅱ. Scope of application
Used in all kinds of high-end tobacco, wine, drugs, cosmetics and other famous products packaging, especially for a variety of adhesive labels and plastic anti-counterfeiting packaging.

Ⅲ. varieties

Red, yellow, green, blue, white, orange and other color and colorless change a variety of color, long, short wave color and other varieties.
Long wave fluorescence (colorless → color) : colorless → red fluorescence: red, orange, white, yellow, blue, green, yellow and green.
Long wave colored fluorescence (color → color) example: red → red fluorescence main varieties are: red, green, blue, etc.
Short wave fluorescence (colorless → color) example: colorless → red fluorescence main grade is: red, white, yellow, blue, grass green, etc.
Short-wave fluorescence (black to red)
Double band fluorescence: colorless long wave red + short wave yellow colorless long wave blue + short wave green red + short wave yellow, etc.

Ⅳ. Technical data
1, the use of colorless fluorescent ink and similar ordinary ink basically the same. In general, it can be used directly. Users can also add some solvents or additives according to the actual needs. The Suggestions are as follows:
Offset printing: mineral oil, ink oil, refined wax, dry powder, slow drying agent, etc
Silk screen printing: 783 diluent, blocking agent, defoaming agent, cyclohexanone, etc
Gravure printing: diluent has slow dry, neutral, fast dry three kinds, the user can adjust
Dry slowly: xylene, butyl acetate, cyclohexanone weight ratio is 1:1:1
Neutral: toluene, butyl acetate, butanone weight ratio: 1:1:1
Quick drying: toluene, butyl acetate, acetone weight ratio: 1:1:1

Colorless fluorescent ink and the same four-color version of the ink into a variety of colored fluorescent ink, but the luminous color and brightness will be added to the ink color and the number of different changes, improper allocation will also affect the ink, users should be under the guidance of the company to modulation, or the use of our company for your special spot color ink.

2, the user in the use of offset or gravure printing colorless fluorescent ink, need to transfer the roller and plate clean, using a new roller is more ideal; Otherwise, very small amounts of colored ink, it is possible to make colorless fluorescent ink with color, affect the appearance of printing quality.

3. Different papers have different effects on colorless fluorescent light. Because most of the paper surface after fluorescent whitening treatment, fluorescent whitening agent in ultraviolet light will emit blue light, so in the paper without whitening agent on the paper containing whitening agent, colorless fluorescent ink color effect has some differences. Need to mention, because of this reason, colorless fluorescent blue ink is not suitable for fluorescent containing whitening paper, otherwise blue fluorescence will be submerged in whitening agent blue.

4, colorless fluorescent ink can be printed in non-pattern parts, can also be printed on the pattern. In order to highlight the fluorescence effect, generally printed in the outermost layer of the pattern.
