Brief about DTP Jobs
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.
Low Cost Prints
Printing labels for various types of products has grown significantly in recent times. Along with new and efficient printing machines, labels can be ordered even at very low costs without worrying about the exorbitant rate. Of course, large outlays are still cheaper, but this difference is not as big as a few years ago.
The potential market for low-cost prints is small, local companies producing small quantities of goods. Recently also a lot of home brewers begin to label their own beers, of course not for trade, but for example for contests. In addition, we have producers of honey, preserves and organic food, where the demand is rather small expenditure labels.
Wikipedia about laser printing
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.
