DTP Operators and Their Work
The DTP operator is a responsible person in printers, publishing houses and wherever materials are printed in large quantities, for the correct preparation of files that will be printed. The task is easy and simple in theory, however, one small error of the DTP operator and the circulation of several thousand copies of newspapers can be thrown away. In this work, many things may go wrong: change of paper for another, new printer with other inks, incorrect conversion of colors. There are also typo errors, bad placement of some element or just a few details. All this can end very badly and bring big losses - so it's work under stress and tension, because if something goes wrong it usually will be just for the DTP operator.
Printing? multiple reflection of an image from a printing form onto a printing substrate (e.g., on paper). Every copy, that is a print, is commonly called a print.
The printing also means various techniques for copying text and graphics using traditional methods, using printing machines, as well as modern computer methods with the use of computer peripherals, such as printers, plotters, etc. - although such prints should be called printouts.
The introduction of computer techniques and digital printing to printers has meant that printing is also often understood as printing done on an industrial scale by means of adapted printing machines.
Water and waterless - offset printing
Offset printing is the most popular type of printing in today's printing industry. It is true that it has many varieties and uses different techniques and materials (paint, paper). The main division is cold printing, where the paint is fixed by soaking into paper. While the 'hot' offset where the printed paper web passes through the drying tunnel.
The classic offset (water) is associated with the use of water rollers and hydrophilic and hydrophobic surfaces, however, this method is already abandoned due to the difficulty in obtaining a good balance of water and oil paint.
The successor of this method is anhydrous offset printing where silicone molds are used instead of water.
