Short about printing
The printing era has been pretty good since Gutenberg. First, important things were printed like books. But these are REALLY important, not some literature for the mob. Well, because the mob was quite illiterate at the time. Then also such fiction was printed, meaning for the reading of the book. Well, since the last 50 years (even hundreds of them), it's all about printing - books, leaflets, business cards, even shirts, mugs, pens ... Well, really everything. Because you need to build brand awareness at the customer, i.e. printing and marketing is an inseparable couple. Because you can print everything on your T-shirt and have it originally. Well, who would prohibit the rich?
Low Volume Labels
Printing labels for various types of products has grown significantly in recent times. 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.
What programs dominate in printers
There are more and more graphics processing programs, from the most popular Photoshop to less known and free ones like Inkscape. Professionals usually use one or two proven programs, which translates into their high productivity.
In the work of graphics or DTP operator you usually need a program for processing vector and raster graphics. You can also include word processors, programs provided by print equipment manufacturers, to the pool of programs needed for such work.
