Imagine that we buy a monitor and its input does not match our video card, even though it has the same type.That's why certain standards apply. In polygraphy and graphics, such standards also exist - appropriate definitions of CMYK colors - key for the appropriate color reproduction. Specified in advance formats for printing leaflets and business cards, so that they are comfortable and as uniform as possible.
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.
