Standard sizes of printer inks are purchased by people with the highest quality printers who do not want to make too many prints or prefer to buy accessories that have generally accepted sizes.
This is because large-size printer inks are usually slightly cheaper or covered by special promotions that make them really attractive.
Along with new and efficient printing machines, labels can be ordered even at very low costs without worrying about the exorbitant rate.Of course, large outlays are still cheaper, but this difference is not as big as a few years ago. The potential market for low-cost prints is small, local companies producing small quantities of goods. Recently also a lot of home brewers begin to label their own beers, of course not for trade, but for example for contests. In addition, we have producers of honey, preserves and organic food, where the demand is rather small expenditure labels.
This is of course very important, but it is equally important to reach for suitable printer paper before making color prints. .
