Why do we need standards?
Standards in every industry and business are important. 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. Without standards, even leaflets could be completely unreadable and even repulsive.
Printer - Wikipedia definition
In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper. The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. The first electronic printer was the EP-101, invented by Japanese company Epson and released in 1968. The first commercial printers generally used mechanisms from electric typewriters and Teletype machines. The demand for higher speed led to the development of new systems specifically for computer use. In the 1980s were daisy wheel systems similar to typewriters, line printers that produced similar output but at much higher speed, and dot matrix systems that could mix text and graphics but produced relatively low-quality output. The plotter was used for those requiring high quality line art like blueprints.
A lot depends on the project, but ...
Everyone likes when the leaflet is colorful, aesthetic and legible. However, a lot depends on the project itself, in other words, graphics preparing the files for printing. He must be aware of the basic matters regarding composition and layout. A well-made leaflet will certainly have a better effect than a short, ugly one.
A lot also depends on the printing house and the selection of paper and the type of printing. A leaflet looks better on shiny and smooth paper than on a torn parchment. The type of paint and the method of printing is also not insignificant, and its selection is best entrusted to a specialist in this topic or to pass on a printing company that has extensive experience with each type of orders.
