About DTP Operators

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.

Shortly about solid ink printers

Solid ink printers, also known as phase-change printers, are a type of thermal transfer printer.
They use solid sticks of CMYK-coloured ink, similar in consistency to candle wax, which are melted and fed into a piezo crystal operated print-head.
The printhead sprays the ink on a rotating, oil coated drum.
The paper then passes over the print drum, at which time the image is immediately transferred, or transfixed, to the page.

Solid ink printers are most commonly used as colour office printers, and are excellent at printing on transparencies and other non-porous media.

Solid ink printers can produce excellent results.
Acquisition and operating costs are similar to laser printers.

Drawbacks of the technology include high energy consumption and long warm-up times from a cold state.

Also, some users complain that the resulting prints are difficult to write on, as the wax tends to repel inks from pens, and are difficult to feed through automatic document feeders, but these traits have been significantly reduced in later models.

In addition, this type of printer is only available from one manufacturer, Xerox, manufactured as part of their Xerox Phaser office printer line.

Previously, solid ink printers were manufactured by Tektronix, but Tek sold the printing business to Xerox in 2001.Źródło: https://en.wikipedia.org/wiki/Printer_(computing)
