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.
Laser printing in Wikipedia
Laser printing is an electrostatic digital printing process.
It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image.1 The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both.
As with digital photocopiers, laser printers employ a xerographic printing process. However, laser printing differs from analog photocopiers in that the image is produced by the direct scanning of the medium across the printer's photoreceptor. This enables laser printing to copy images more quickly than most photocopiers.Źródło: https://en.wikipedia.org/wiki/Laser_printing
Almost every company needs certain printed articles, or if you prefer printing.
Leaflets, banners or posters are the main means of advertising for many companies, especially for local and small ones.
Well designed leaflets or business cards can attract many customers, and badly made to scare away and discourage our brand, company or product.
Therefore, it is necessary to pay special attention to the quality of these materials, also in terms of technology of doing these things in the printing house.
