"Hahahaha......" Xiao Yi let out a presumptuous and exaggerated laugh: "Print? Printing, you say? You're not mistaken, right? Don't you know that printed works have very distinct characteristics? ”

"Characteristics, I don't know what characteristics Mr. Xiao is talking about?" Yu Fei asked unhurriedly, compared to Xiao Yi's eagerness, Yu Fei's bearing didn't know how many times better! This made many people present sigh that it seems that age and cultivation are not directly proportional.

Wang Qiucheng also sighed, he didn't expect to come to this point in the end, I'm afraid that this time the world's treasure show, the final expert showdown will be the biggest highlight, right?

"Teacher Yu, listen up." Xiao Yi snorted coldly from his nose, as if an elder was guiding his juniors: "The ink of the printed matter is not as stretched and free as the ink used for calligraphy and painting, and although the color of the calligraphy and painting works and the color of the printed matter look very similar, there are still some differences when you carefully distinguish them." At the same time, if you smell it with your nose, there is no smell of ink in the print, and some only smell of ink. Third, and most importantly, with a 10 to 20 times magnifying glass, it can be seen that the printed matter is composed of different ink dots, which are called outlets in the printing industry, because printing needs to be screened to achieve a variety of effects, such as from shallow to deep, from light to dark, etc., which need to be achieved by outlets. ”

Xiao Yi talked eloquently, and explained the distinction of printed matter very clearly in a few sentences.

Then he looked at Yu Fei with a smug face, "But if you look at Mr. Wang's painting again, the ink is stretched freely, and the brushstrokes are clear." Xiao Yi put a magnifying glass on the painting, "With the magnifying glass, there are no ink spots." Teacher Yu, you can't have too much paranoia just now, right? ”

Xiao Yi's last sentence was very frivolous, which was equivalent to a direct personal attack. Such unqualified behavior surprised many people. However, Xiao Yi also has some truth in saying this.

There are mainly types of traditional counterfeiting: one is copying, which is one of the important means for painters to learn Chinese painting. This is more common, but usually the artistic value of the copied work is not high. Of course, there are exceptions, Mr. Zhang Daqian liked to copy when he was learning to paint, and many of his copied works have reached the level of fake. Even at the auction house, the price is higher than the original!

The second is imitation, which is also the most common means of counterfeiting.

The third is to make a false wall, which is a kind of fabrication, that is, a subjective fabrication according to the characteristics of calligraphers and painters, which is the lowest technical means of counterfeiting, but it can also deceive people, especially those who hunt for curiosities in the collection, always take it for granted that this is reasonable, and end up receiving a room full of strange blind work.

The fourth is the falsification of semi-finished products, which the painter himself paints halfway through. If it is not completed, the counterfeiter will complete the completion and impersonation, and this kind of work is half-true and half-fake, which is difficult to identify.

The fifth type is dedicated to the falsification of ancient albums, called the "sleet" category. Copying the original album and rebinding it into two albums in a staggered manner is a mixed practice.

The sixth type is a fake painting with a real inscription or a real painting with a fake inscription.

The seventh is to ask someone to write on my behalf, which exists in both ancient and modern painters. Especially for some authors whose works have a better market situation, because their works are in short supply, the author will ask someone to write on his behalf when he has no time to doppelgänger.

Of course. With the progress of science and technology, there are high-tech counterfeiting methods such as watermark ink, computer engraving, framing and aging, and copying of old rice paper.

But as Xiao Yi said, there will be ink spots left on the print, which is like the "birthmark" of the print, which is the main difference between the reproduction and the hand-painted work, which can be said to be irremoparable.

Xiao Yi's rebuttal evidence is very favorable. All unfavorable spearheads are pointed at Yu Fei.

"In the end, I am young, although I am very knowledgeable, but there are still times when I look away." An audience member said with regret.

"I see that Teacher Yu's eyesight is there, but he is a little too impulsive." Another audience member said, "Didn't you see that Mr. Yu didn't look at that painting carefully from beginning to end?" ”

Seeing Yu Fei's "speechlessness" when questioned by Xiao Yi, Wang Qiucheng, Ouyang Xia and even Li Sisi were secretly anxious for him.

"Mr. Wang. Does your collection catch my eye? Yu Fei originally wanted to refute Xiao Yi directly.

But thinking that he hadn't looked at the painting carefully, if he knew that the details seemed too unreasonable and arbitrary, he was afraid that it would arouse suspicion, so Yu Fei took a step back.

"Teacher Yu, please." Although Yu Fei questioned that Mr. Wang's painting was printed, Mr. Wang was not angry and still cooperated and handed the painting to Yu Fei.

So, under the attention of everyone, Yu Fei opened the "Detachment Map" again.

The large screen at the scene clearly displayed the image of "Huang Litu".

Looking at this exquisite painting, the audience was full of discussions.

"This painting should be genuine! Teacher Yu made a mistake in the appraisal this time. One audience member said.

"Not necessarily, the painting is too perfect, there must be something wrong. I support Teacher Yu. Another viewer retorted.

Fortunately, Yu Fei only looked at it for less than a minute, then stood up straight and said confidently: "I insist on my opinion, this painting is indeed a print!" ”

"Huh?" The scene couldn't help but think of a burst of exclamations. You must know that many people still think that Yu Fei proposed to look at the painting to find himself under the stairs. He could have said that he had been negligent because he had not carefully appraised the painting, and after the appraisal just now, he could already conclude that the painting was indeed genuine.

But what he didn't expect was that he still insisted that the painting was fake. That means that he must overturn Xiao Yi's evidence one by one, and at the same time point out the errors of this painting one by one.

Xiao Yi's argument is very favorable, can the young Yu Fei do this? This is what many people suspect.

"Teacher Yu, there is no evidence, let's come up with convincing evidence." Xiao Yi said disdainfully.

"Teacher Xiao, don't be impatient." Yu Fei always has an unhurried posture, "Teacher Xiao's appraisal just now really didn't have the slightest problem in the past. However, as far as counterfeiting is concerned, both technology and technology are improving with each passing day, and in order to accurately distinguish the authenticity, it requires our identification methods to keep pace with the times, constantly absorb new knowledge, and improve it. Only when the magic is one foot high and one foot high, can all the counterfeiting methods be hidden. ”

"Teacher Yu, don't fix the useless ones, you just need to say that there is something wrong with this painting." Xiao Yi said impatiently, completely forgetting how wordy and annoying he was when he identified it just now.

"Good! As you wish. Yu Fei said: "You may not know that in 1999, the United States Hewlett-Packard developed a pigment inkjet printing equipment, this kind of equipment will be scanned when copying fake paintings, collect data and input it into the computer; Then the colors displayed by the computer are converted into printing colors, that is, the four primary colors of yellow, magenta, blue and black; Finally, it is necessary to control the distribution of ink droplets and print the work. In the printing process, the color and position are controlled by the computer program, which is very detailed. Therefore, the pigment ink used is more similar to the pigment used in calligraphy and painting, and can be printed directly on uncoated rice paper. Micro-inkjet technology makes the ink dots small, and the ink dots of the printed work are difficult to observe. At the same time, counterfeiters will also choose to use laser plate making, and then use related technology to eliminate outlets, so that the detection method can not catch the handle. ”

"What?" Yu Fei's words completely subverted everyone's common sense about the identification of calligraphy and painting works, if the printed matter cannot be checked for ink spots, then how to check it.

"Nonsense!" Xiao Yi retorted: "If such technology comes out, then why don't I know, and why haven't I even encountered such a fake work?" ”

"It's simple." Yu Fei said with a smile: "Teacher Xiao is immersed in the appraisal of antique calligraphy and painting every day, where can I have time to pay attention to the latest technological innovations?" Not to mention that you haven't encountered such a fake work, isn't it just one that is in front of us now? ”

Yu Fei also learned the news by chance. Although the Chaos Qi was able to identify the painting as inauthentic, it was still too difficult to find a convincing reason. Yu Fei thought of the kind of technology he had seen before.

Xiao Yi wanted to refute, but heard someone say, "Yes, there is indeed such a technology." ”
