It must be admitted that people who already use printers already know very well in which stores they can buy cheaper accessories that have the same good quality as their most expensive counterparts.
Very often, the prices of their purchase have been reduced because the owners of particular stores wanted to sell a new type of accessories or increase the level of sales of goods brought by them.
Of course, they try to lower the prices of those products that have a chance for the highest sales, which is why they introduce rebates on inks and toners as well as photocopying and cleaning materials.
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.
As a result, they have the certainty that their prints will look almost perfect, and certainly very clearly.
