The specificity of color printouts lies in the fact that they must be made using the highest quality inks and toners. Otherwise, they will not make a good impression on customers coming to the photocopier and they will just quickly fade. Meanwhile, the use of colored inks often saves important tables or the most important statements appearing in books. Therefore, all people who make color prints want to use multi-colored inks that perfectly reproduce the color of the document to be printed. This is of course very important, but it is equally important to reach for suitable printer paper before making color prints.
Who today does not have a printer at home. Their prices are becoming more affordable and operating costs lower. Multifunction devices offer increasingly larger scanning resolutions, less margin, larger formats, etc.
But still, such home printers are far behind the professional equipment used in professional printers. Not to mention the much larger range of techniques used, which have nothing to do with those we know from home printers. Printed roll, solvent, water, anhydrous - long to exchange. The quality of such printouts is higher, which entails the obvious higher costs of printing itself.
Printing at printing plants and printing plants
Paints, inks, paper, toners, foils and other consumables - these are things that can not be missing from printing plants. They are ordered wholesale and also consumed in bulk. For each order, the production costs are optimized, and the appropriate technique and type of printing is selected.
Graphic designers, DTP operators and printers deal with this. They are responsible for the quality of the printout and as soon as something is wrong they are the first to be targeted by the dissatisfied boss. Their work is quite hard and I have to admit that you have to really have a fuss to do it. Work after hours, maximum focus and responsibility - definitely not work for everyone.
