It is difficult to imagine what humanity could have been if paper and the printing process had not been invented. Works of art are published on paper, scientific papers are printed, and interesting news is published. However, despite the amazing variety of books, newspapers and magazines, it is easy to see that there are not many page sizes of various publications of various sizes. How can I measure the sheet size of a particular format? The basis for considering this issue is a printed sheet.
Here we will try to openly look at this situation through the eyes of an ordinary person. What paper formats in real life does he see around him? Briefly list them. These are standard sheets of
writing paper, sheets of newspapers in several versions, several different book formats. How to bring this diversity to one basis? If we took a standard sheet of paper as a basis, then how to express other
paper sizes based on it? But here the traditional solution to this issue comes to the rescue. It so happened historically that a printed sheet of sixty centimeters by ninety centimeters was selected as the base size, which was called the “conventionally printed sheet”. Usually books, newspapers and magazines measure their format in relation to it. A reference is a printed sheet filled with text on one side. These concepts must be distinguished from the concept of “physical printed sheet”, which means a real printed sheet of a publication.
Thus, the volume of any printed publication, for example, books, newspapers or magazines can be estimated in relation to the conditional printed sheet. Let's try to show this with an example. Suppose we are talking about a book whose format is 70cm x 100cm / 16, which has 192 pages. In order to calculate the volume of the book, you need to carry out the following calculations. Conventionally, a printed sheet has an area equal to 60x90 = 5400 square centimeters, a physical printed sheet - 70 cm x 100 cm = 7000 square centimeters. The conversion factor is 7000/5400 = 1.29. The final calculation looks like this: (192/16) x1.29 = 15.48. So, in our case, we can say that the volume of the book in question is 15.48 conditional printed sheets. Thus, it is customary to indicate the volume of the printed publication.
To complete the picture in this matter, it should be noted that two more standard types of printed sheet are common. This is an author's printed sheet and registration and publishing sheet. The first of them has several measurement methods (40,000 typed characters with spaces or 700 lines of poetic text or 22-23 ordinary typewritten pages) and is designed to measure the volume of copyright work submitted for printing. The second takes the same size as the author's printed sheet, but does not include the
advertising material present in this publication.
The printed sheet, as it turned out, is of different types, which is useful to understand. This concept plays a large role in publishing. It allows you to really assess the amount of printing work performed when publishing a book.
