Tricks to identify the authenticity of 50 RMB

Counterfeit RMB refers to counterfeit RMB made through mechanisms, rubbings, engravings, photography, depictions, etc. Among them, machine-made counterfeit coins produced by electronic scanning color separation plate printing have the largest number, the highest level of counterfeiting, and the greatest harm. So, do you know how to identify the authenticity of RMB? Now, let’s learn it!

Recognition skills of authentic and fake RMB

The first way to identify counterfeit currency Tip: Look at the cutting and pasting marks

Why should you pay attention to the cutting and pasting marks on the banknotes? Because this is a typical feature of "pieced together counterfeit coins". Criminals cut and divide the counterfeit currency and the genuine currency separately and then put them together. This will make the counterfeit currency have part of the face characteristics of the real currency. If you only check the face part of the genuine currency during identification, it will be very difficult. It is easy to cause misreceipt. In many confiscated "pieced-together counterfeit currency", the proportion of the face value of the genuine currency is often greater than the proportion of the face value of the counterfeit currency, which further increases the deceptiveness of such counterfeit currency.

So how should we identify such suspicious coins when we encounter them? First, we can divide the note surface into several relatively complete areas based on the cutting and pasting marks, and then check each area separately. Anti-counterfeiting features, in order to infer whether it is made of authentic and fake banknotes.

The second trick to identify counterfeit currency: check the watermark

Watermark is a classic and traditional anti-counterfeiting technology for banknotes. Although it is called a "watermark", it is by no means "printed" on banknotes! In the papermaking process, complex equipment and processes are used to cause specific changes in the distribution of paper fibers. Parts with dense fiber distribution have higher light transmittance. Weak, the color looks darker; the parts with sparse fiber distribution have strong light transmittance, and the color looks lighter. This difference in light transmittance forms a watermark pattern. Therefore, the watermark is embedded in the paper. It is an integral part of the banknote paper and is integrated with the paper. The seemingly simple watermark pattern actually requires large-scale, sophisticated industrial equipment to produce. The technology is complex and the cost is high, making it difficult for counterfeiting criminal gangs to create real watermark patterns.

Step one: Facing the light source, observe the watermark pattern in a light-transmitting state. At this time, the watermark pattern on the genuine coins has a strong three-dimensional effect and the characters' expressions are lifelike; while the watermark patterns on the fake coins appear dull and the characters' expressions are dull.

Step 2: Facing the light source, place the banknote in a horizontal position and observe the watermark surface under opaque conditions. Some counterfeit banknotes use colorless or light-colored ink to print watermark patterns on the front and back of the banknotes to fake the watermark effect. For this kind of counterfeit currency, when we place it in a horizontal position facing the light source, a clear watermark pattern can be observed from the watermark window on the front or back, and the color is darker. However, the watermark pattern cannot be seen on the genuine currency at this time. .

Step 3: Check whether the paper on the left side of the ticket is abnormal. Some counterfeit banknotes simulate watermark patterns by coating white slurry on the paper interlayer. The characteristics of this kind of counterfeit currency are: the paper near the watermark pattern is obviously thicker, and when viewed under light transmission, it is obviously darker than the note on the right side; if the counterfeit currency paper has been uncovered and pasted together, you will find many wrinkles if you look closely. feel.

The third trick to identify counterfeit currency: check the denomination numbers that will change color

The fifth set of RMB 100 yuan coupons and 50 yuan coupons The denomination number on the lower left side of the front of the yuan note is printed using special optically variable ink and gravure printing. This ink is one of the more complex types of modern anti-counterfeiting inks, with pearlescent and metallic effects that are impossible to copy with color copiers and electronic copiers. Its characteristic is that when it is illuminated by light, you will see completely different colors when viewed from different angles. This printing feature cannot be imitated by any other ink and printing method.

We place the face of the banknote in a position perpendicular to the line of sight and observe the denomination number on the lower left side of the face. At this time, the color of the denomination number on the 100-yuan coupon is green, and the color of the denomination number on the 50-yuan coupon is gold. Yellow; then we slowly tilt the face of the ticket. When the face of the ticket is tilted to a certain angle, the color of the face number of the 100 yuan coupon turns to blue, while the color of the face number of the 50 yuan coupon turns to green.

If the banknote in your hand is counterfeit, the color will not change no matter how you change the viewing angle. Of course, among the counterfeit coins discovered so far, there are also attempts to forge the anti-counterfeiting effect of optically variable ink. The counterfeiting method is to mix pearlescent powder into ordinary ink, so when the banknote is turned, it will show a certain "flash" feature as the viewing angle changes. This kind of counterfeit currency is actually easier to identify, because this "flash effect" only simulates the metallic texture of the face value number of the light-changing ink of the real currency, but it will never produce the same color change as the real currency.

The fourth trick to identify counterfeit currency: check the printing pattern

The complementary printing pattern of yin and yang. Applicable to the 100 yuan, 50 yuan, and 10 yuan coupons of the fifth set of RMB in the 1999 version and the 100 yuan, 50 yuan, 20 yuan, and 10 yuan coupons in the 2005 version. There is a circular partial pattern printed on the left side of the front and the right side of the back of these coupons. When we observe through the light, the two patterns will accurately overlap and form a complete ancient coin pattern.

The above patterns are printed using counter-printing technology. Counterfeiting technology is by far the most effective anti-counterfeiting technology in offset printing. It is a special function of special banknote printing machines. It feeds paper at one time and prints the front and back at the same time, so it can produce overlapping and accurate counterfeiting patterns.

The correct way to identify the fifth set of RMB printing patterns is: face the light source and observe through the light to see whether the two patterns on the front and back can be accurately connected; if it is a counterfeit currency, check the two patterns on the front and back. The pattern will appear misaligned.

The fifth trick to identify counterfeit currency: touch the gravure printing pattern

The engraving gravure printing technology is similar to the traditional offset printing technology Big difference. Before printing, the ink is stored in the grooves of the metal printing plate. During printing, the ink is transferred to the paper through huge pressure. At this time, part of the ink penetrates into the paper, and the other part of the ink "accumulates" on the paper. . The characteristics of engraving gravure printing are fine printing patterns, obvious raised hand feel and unique three-dimensional effect, which are visible, touchable and highly recognizable to the public; the printing plate, ink, printing process and equipment used in engraving gravure printing The technology is complex, the investment is huge, and the cost is expensive. There has always been a saying in the banknote printing industry that "there is no banknote without concave", and engraving and gravure printing is one of the most effective anti-counterfeiting technologies currently.

Step one: Check the "touch" of the pattern by touching it with your finger. The fifth set of RMB features Mao Zedong's portrait on the front, denomination numbers, the name of the People's Bank of China, the national emblem, Braille symbols, gravure touch lines and the main scene on the back. The ink of these patterns is higher than the paper surface, and you will feel strong when you touch it with your fingers. The surface of the banknotes feels smooth when touched.

Step 2: Place the note in a horizontal position facing the light source, and check whether there are any traces of forgery on the front and back of the gravure pattern. In recent years, in order to simulate the concave and convex feel of real banknotes, some counterfeiters use tools to make indentations on the front or back of counterfeit banknotes in an attempt to pass them off as genuine. When identifying such counterfeit banknotes, if we only rely on finger touch to distinguish, It is extremely easy for misjudgment to occur. Therefore, it is recommended that when you have doubts about the "touch" of banknotes, choose the direction facing the light source (including sunlight), place the banknote in a horizontal position, and carefully observe whether there are any traces of mechanical or hard tool extrusion on the front and back of the banknote.

The sixth trick to identify counterfeit currency: check the invisible text

The fifth set of RMB denominations of each note There is a decorative pattern on the upper right side of the front.

When we look at the banknote from the vertical direction, we cannot see the hidden content, but when we turn the banknote to a certain angle, the denomination number of the banknote will be revealed.

Why are these denomination numbers looming? When you carefully observe the face of the note with a magnifying glass, you will find that these invisible patterns are composed of groups of parallel lines that are raised on the paper. It is based on The refraction phenomenon produced by these raised ink patterns achieves the invisible effect. Therefore, the invisible denomination numbers are also based on engraving and gravure technology. As we mentioned in the previous content, other commercial reproduction technologies and modern digital reproduction technologies cannot replicate this effect. Therefore, it is copy-proof, proprietary, easy to identify, and has a good anti-counterfeiting effect. Since the 1990s, most countries have chosen this anti-counterfeiting measure when revising or changing their currencies.

Step one: Observe the invisible denomination numbers vertically. The denomination number should not be visible at this time. If you find that the denomination number has appeared at this time, it is most likely that the counterfeiter used colorless or light-colored ink to forge it.

Step 2: Change the angle to observe the invisible denomination numbers. Please note that the observation methods of the invisible denomination figures of the fifth set of RMB in 1999 and 2005 are slightly different. If you are holding the 1999 version of the fifth set of RMB, you can place the banknote close to parallel to your eyes and rotate it horizontally at a 45-degree or 90-degree angle facing the light source. At this time, the denomination number of the banknote will appear; As for the 2005 version of the fifth set of RMB, you only need to place the face of the note close to parallel to your eyes and tilt it up and down facing the light source to observe it.

The seventh trick to identify counterfeit currency: use simple tools

As anti-counterfeit currency obligation propagandists, we While actively teaching anti-counterfeiting knowledge to the public, it also accepts consultation anytime and anywhere to help people around them identify "suspicious currencies". Therefore, we suggest that while mastering some basic public identification methods, you should also learn to use some simple identification tools, which will help you make more rapid and accurate judgments. Below we will take a magnifying glass as an example to introduce several simple and easy identification methods.

1. Use a magnifying glass to detect the engraving gravure printing pattern. This is a powerful supplement to the touch method for detecting the characteristics of gravure printing patterns. The bank names, denomination numbers, Mao Zedong’s portrait, Braille symbols, etc. of the fifth set of RMB notes all use the engraving gravure printing process. We can use a 5 to 10 times magnifying glass to observe the printed lines. If it is a genuine coin, we can observe that the lines are raised on the surface of the paper, with a certain thickness of the ink layer and a three-dimensional effect, and the lines are clear and continuous; if it is For counterfeit currency, the lines are completely penetrated into the paper, there is no convex effect, and the printed lines are composed of dots and are not continuous.

In addition, as we mentioned in the previous article, some counterfeiters use pointed tools to pressurize the gravure parts to fake the concave and convex feeling. This method of counterfeiting changes the flatness of the note surface, leaving obvious indentations. We can more easily detect these flaws with the help of a magnifying glass. The concave and convex parts of the counterfeit currency are inconsistent with the pattern and texture, and are messy.

2. Use a magnifying glass to detect the microtext on the ticket. Each banknote in the fifth set of RMB has microtext printed in multiple places. For example, we can find them on the top of the front of the 100 yuan, 50 yuan, 10 yuan and 5 yuan banknotes, and on the right side and bottom of the front of the 20 yuan banknote. You must know that such a fine printing process cannot be completed by ordinary printing machines! When we observe it through a magnifying glass, we can find that the microtext on the genuine coins is clearly legible, while the microtext on the counterfeit coins is blurry.

How to identify the authenticity of 50 RMB notes

1. Features of the face value

The main color is green, the ticket length is 150mm and the width is 70mm. The main scene on the front is Mao Zedong's head, the left side is a flower image, the upper left corner is the People's Republic of China and the national emblem pattern, the lower right corner is a Braille denomination mark, and the front of the ticket has double horizontal and vertical numbers printed on it.

The main scene on the back is the "Potala Palace" pattern, and the upper right side is "People's Bank of China" in Chinese pinyin and the words "People's Bank of China" and the denomination in the four ethnic languages ??of Mongolian, Tibetan, Uighur and Zhuang.

2. Anti-counterfeiting features

1. Fixed portrait watermark: Located in the blank space on the left side of the front, when viewed through the light, you can see Mao Zedong, who is the same as the main portrait and has a strong three-dimensional effect. Avatar watermark.

2. Red and blue colored fibers: On the ticket surface, you can see irregularly distributed red and blue fibers in the paper.

3. Magnetic microtext security thread: The security thread in the banknote paper is magnetic when viewed through the light, and the microtext "RMB50" can be seen. The instrument detects it.

4. Hand-carved avatar: The main portrait of Mao Zedong on the front is hand-engraved and gravure printed. The image is lifelike, expressive, has a strong sense of concavity and convexity, and is easy to identify.

5. Invisible denomination numbers: There is a decorative pattern on the upper right side of the front. Place the banknote close to parallel to your eyes and rotate it 45 degrees or 90 degrees facing the light source to see the denomination numbers. ?50? words.

6. Offset microtext: In the pattern on the top of the front, there are offset microtext "50" and "RMB50" printed in many places.

7. Optical changeable ink denomination number: The denomination number "50" on the lower left side of the front appears gold when viewed perpendicular to the face of the note, and turns green when tilted at a certain angle.

8. Yin and yang complementary printing pattern: There is a circular partial pattern on the lower left side of the front and the lower right side of the back. When observed in the light, you can see that the front and back patterns merge to form a complete ancient coin pattern.

9. Engraved gravure printing: Mao Zedong’s portrait as the main scene on the front, the name of the People’s Bank of China, Braille denomination numbers, Braille denomination marks and the Potala Palace pattern as the main scene on the back are all engraved intaglio. Printing, there is an obvious concave and convex feeling when you touch it with your fingers.
