1, look at the appearance
Specifically: look at the cover first. Compared with genuine books, the cover of pirated books is often incorrect, dim or gorgeous, and the color matching is also mixed. In addition, the press and publication administration stipulates that it is strictly forbidden to attract readers with pornographic and murderous words and pictures, while most of the covers of pirated books have irritating pictures such as obscenity, murder and violence; Pirated books are often marked with inflammatory directories on the cover, or even replaced by directories, or the font of directories is larger than the title; In order to sell for a long time, the distribution and volume of some publications are deliberately blurred.
2. Look at this binding
According to the practice of the publishing industry, a genuine book with more than 200 pages often abandons wire binding and adopts lock binding, plastic binding or wireless binding. However, due to the limitation of printing and binding equipment or the consideration of reducing cost, pirated books with 300 pages and more than 400 pages are usually bound with iron wire. Moreover, the binding quality of pirated books is very poor, the folding is not straight, and there are many pages missing or even knives. Due to loose binding, the covers of some books can be separated from the whole book.
Step 3 read paper
Books should be printed on both sides. If the paper is too thin, it will easily mix with ink, resulting in blurred handwriting. Therefore, except for dictionaries, the original book paper is more than 52 grams. Once you meet a book with thin paper, most of the handwriting on the other side can be exposed as pirated books.
4. Look at clarity and error rate.
After the original book is opened, the handwriting is particularly clear and the ink is sprayed evenly, while the pirated book is illegible and the ink is deep and shallow, and the overall feeling is rough printing.
There are too many typos in pirated books, and the error rate is very high, for example; There are blank pages, few pages, and some pages are bound backwards. In short, books with high error rate are pirated books.
5. Pay attention to the price of books
Because pirated books from paper, typesetting to printing, the cost is very low, and they don't pay the remuneration, so they evade taxes. Therefore, vendors often sell a book marked 60 yuan at a price two or three times lower than the marked price, and he will sell it to you at 15 yuan. Most of the new books sold at half price on the stalls are pirated books.
6. Source
It is best to choose some bookstores with large scale and good credit when buying genuine books, because these sellers generally have more legitimate purchase channels. If you are not sure whether the book you want to buy is genuine, you must find the seller to understand the situation and let the seller make a guarantee. After buying a book, if you find that you have the characteristics of some of the pirated books mentioned above, you should immediately report a complaint to the relevant department and ask the seller to return it.
Pirated publications usually include pirated books, pirated software, pirated audio-visual works and pirated online knowledge products. Piracy, that is, the proverb "D version". This violates the law, and property buyers are not protected by law. Among them, pirated books are one of the most common pirated goods.
As far as printing quality is concerned, there are two main types of pirated books:
1, low-end pirated books. The overall printing quality is poor and easy to distinguish. It is manifested in the following aspects: poor paper (thin paper, yellow and gray), uneven ink color, hue deviation, inaccurate overprint, blurred image, tape marks or imposition marks on the edges of pictures and texts, uneven cutting of finished products, poor binding quality (many quality problems such as missing lines and wrong pages), and many text and punctuation errors (some typos can reach more than ten yards).
2. High-end pirated books. The overall printing quality is high, which is not much different from the original book and difficult to distinguish. The paper is better, the ink color is more uniform, the hue is better, the overprint is more accurate, the image level is clearer, the finished product is cut more square, the binding quality is better, and there are fewer text errors.
Generally speaking, low-end pirated books are printed by small printing houses or underground printing houses with low-end equipment, and some small pirated booksellers operate in a piecemeal and guerrilla way. High-end pirated books are printed by powerful large-scale pirated booksellers using high-end equipment, and some even use imported equipment.
It can be said that the current pirated books are mainly low-end pirated books, and this situation will continue for quite some time, but we should also see a small number of high-end pirated books. Therefore, we cannot simply think that "pirated books are not the ones with good printing quality, but the ones with poor printing quality", nor can we blindly think that "pirated books must be cheaper than genuine books".
The most accurate way to distinguish pirated books is to compare them with genuine books published by publishers with the same paper, printing and content, and also to check the copyright page of books (the copyright page of genuine books must include the cataloging data of books in publication, the name and address of publishing unit, the format and version of books, etc.). ), the international standard book number and bar code mark are complete and clear, and if necessary, consult the publisher of genuine books. Of course, if there is an anti-counterfeiting mark, it is still not difficult to distinguish.
