Hur berättar du vilken tryckning en bok är?

Identifying the printing type of a bookFor book lovers, collectors, or people who simply focus on reading quality, knowing how to identify the printing type of a book is by no means an insignificant skill. Different printing processes not only affect the visual effect and tactile experience of books, but are also closely related to the preservation time and collection value of books. This article will focus on "how do you tell what printing a book is" and integrate the Popularisering av tryckteknologi med praktiska identifieringsmetoder som hjälper dig att identifiera vanliga bokutskriftstyper exakt som offsetutskrift, digitaltryck, bläckstråle -utskrift och laserutskrift genom observerbara funktioner .
The basis of book printing identification Commonly used printing processes for books Before learning to identify, we need to understand the four major printing processes commonly used in book production. Offset printing, the most widely used traditional printing method, transfers the image to the rubber cloth through the printing plate and then transfers it to the paper. It is suitable for mass printing of books with stable content, such as bestsellers, classic works, etc. Digital printing, a technology that prints directly from digital files without printing plates, is suitable for small-scale printing, such as personalized books and limited edition publications. Inkjet printing uses a nozzle to spray ink onto paper to form an image. It is often used in books with rich color pictures, such as art albums and photo albums. Laser printing relies on laser technology to transfer toner to paper and fix it by heating. It is common in document printing and small-batch books with high text clarity requirements. The core indicators for identifying printing types are to observe specific characteristics, which can be summarized into four aspects. The clarity and smoothness of the edges of text and pictures. Color expression of color saturation, layering, and uniformity. Paper adaptability The℃of matching between the printing process and the paper (such as thickness and texture). Although printing cost and batch cannot be observed directly, they can be combined with other characteristics to assist in judgment. Offset printing has obvious characteristics that are easy to identify. The edges of the images are smooth and clear, without burrs. Due to the principle of indirect transfer, the ink layer is uniform and there is no obvious ink piling at the edges. Color expression of natural and soft colors with good layering. For books with continuous tone images (such as landscape photos), the color transition is smooth and there are no obvious color blocks. Dot performance Observed through a Förstärkningsglas, kan man se att prickarna är regelbundna och arrangerade i en viss vinkel, som är ett typiskt drag i offset -tryck . Touch och Auxiliary Identification of Paper, Offset Printing är mestadels för böcker som är tryckt på Courated Paper eller Offset Paper. ytan på coated papper är smidigt och glansigt, vilket kan visa sig bättre papper eller offset papper. ytan på coated papper är smidigt och glansigt, vilket kan visa att det är bättre att utvisa papper som är bättre att skriva ut. Måttlig struktur och är lämplig för böcker med text som huvudinnehåll . Batchbedömning, offset-tryck kräver platta, så storskalig tryckning (vanligtvis mer än 1, 000 kopior) har mer kostnadsfördelar . om en bok är en bästsäljare och har en stor omgivning, det är troligt att det är offset för att skriva ut 2) has significantly different characteristics from offset printing. Due to the direct injection or transfer of ink/toner, the edges of small text may have slight burrs, but this defect is gradually being eliminated with technological advances. Color performance The color saturation is high, but the layering of continuous tone images is slightly inferior to offset printing. In areas with high color density, slight "Powdering" kan förekomma (toner är inte helt integrerad med papperet) . Personliga spår och spårar digitala tryckningar Stöd variabel datutskrift . Om det finns personliga element i samma batch av böcker, såsom olika presentsidor, anpassade omslag, etc .}, de är i princialt tryck {36 {36} tryckning) genom att skriva ut dig digital) adaptability to paper and can be printed on special papers such as thick cardboard and textured paper, which is difficult to achieve with traditional offset printing in small batches. For uncoated paper, you can check the back of the printed page. The ink penetration of digital printing is shallow, while offset printing may have a slight ink penetration phenomenon. Identification of Inkjet -utskrift och laserutskrift i böcker . Hur identifierar man bläckstråle? Inkjet printing is more common in color albums and personalized publications. The key points for identification are as follows: the ink is highly water-soluble. If you gently drop a small drop of water on the blank area next to the picture, be careful not to damage the book. The ink may smudge slightly. This method is only used to test uncoated paper books. The color of the image inkjet printing is bright, and the color gradient transition is natural. Under a magnifying glass, you can see that the image is composed of tiny ink droplets, and the arrangement is not as regular as offset printing. It is mostly used for special paper for inkjet. This type of paper has a coating that can quickly absorb ink, so the paper surface is relatively smooth and has good waterproof properties. Characteristics of laser printing in books. Laser printing is often used for small batches of text books or internal materials. Its identification characteristics are: Toner characteristics. Toner is in powder form and is fixed to the surface of the paper by heating. If you gently scratch the text with your fingernail, there may be slight toner shedding, especially for laser prints of poor quality. The text is very clear and the black is pure. For books with a large amount of text, laser printing can maintain consistent clarity on each page. Because the toner is heated and fused, there may be a slight bright edge on the edge of the printed area under light, which is a unique feature of laser printing. Comprehensive identification method From the cover to the inner page, the cover is the first part to be observed when identifying the printing type. The offset printed cover has uniform color, and the post-processing such as hot stamping and embossing is well combined with printing. The coated paper printed cover has a smooth surface and rich colors. Digitally printed covers can achieve complex patterns and personalized designs. If the cover has gradient colors or small text, and the edges are slightly blurred, it may be digitally printed. Inkjet printing covers are brightly colored and suitable for covers with rich pictures. Due to the ink layer, the surface may have a slightly rough texture. The inner pages of books can better reflect the characteristics of the printing process. Text pages For books with mainly text, observe the clarity of the text. Offset printing has smooth edges, laser printing has pure black, and digital printing may have slight Burrs för liten text . Bildsidor För böcker med bilder, kontrollera färgövergången och prickarrangemanget . Offset Printing har regelbundna prickar och naturliga övergångar; Inkjet -tryck har ljusa färger och oregelbundna prickar; Digital tryckning har hög färgmättnad men något dåligt skiktning . med hjälp av ett verktygsförstoratglas är ett viktigt verktyg för att identifiera trycktyper, som kan hjälpa till att observera formen på prickar, arrangemang och bläck/tonerfördelning .. of laser printing toner is slightly stronger. Identifying the printing type of books For readers to choose books that are suitable for reading habits, offset printing books have clear text and comfortable paper, which are suitable for long-term reading. The content of digitally printed books can be updated in a timely manner, which is suitable for reading books that need to be revised frequently, such as professional Läroböcker . Inkjet -tryckta böcker har goda färgeffekter och är lämpliga för att läsa konst- och fotograferingsböcker . För samlare för att utvärdera insamlingsvärdet, är bevarandeprestanda för offsettryck av klassiska verk med stor cirkulation stabilt; some limited edition books using special digital printing processes may have unique collection value because of their personalization. Understanding the printing type can help collectors better judge the rarity and preservation difficulty of books. For buyers to avoid being misled by prices, the costs of different printing processes are different. The initial platemaking cost of offset printing is high but the unit cost of large batches is low; Digital utskrift har ingen platemakingkostnad men enhetskostnaden för små partier är hög . att förstå utskriftstypen kan hjälpa till att bedöma om priset på boken är rimlig .
Från observation till att förstå charmen med tryckteknologi är det inte bara en färdighet att kunna identifiera utskriftstypen, utan också ett sätt att förstå kombinationen av teknik och kultur . varje sida i en bok bär spåren av tryckteknik - de smidiga kanterna av offset -tryckning, de personliga egenskaperna hos digital, de ljusa färgerna för blinkstryck, och den tydliga texten med laser -tryck .}}}} -kontrollen) är inte enskilda eller en enda tryckning) är det inte att skriva ut den personliga trycket) technology, but also the guarantee of reading experience. Mastering the identification method, we can not only better choose and appreciate books, but also feel the progress of printing technology. Whether it is the traditional process of offset printing or the innovative technology of digital printing, they all serve the dissemination of knowledge and the inheritance of culture. In the future, with the development of printing technology, more new types of printing may appear, but Så länge vi behärskar de grundläggande principerna för erkännande kan vi alltid identifiera dem exakt .
