Of all the innovations in the world, printing is the biggest. To begin with, printing was mechanical. Later, there was a shift to digital printing. Digital printing can be customised. Diet Coke bottles can have different patterns, no two alike. The changes can be made on the go. You can put a customer’s name on the each bottle.Traditional printing is okay for long print runs. When the print runs are small, the digital printing is the only option. It has immense power. You can print anything from wall paper to T-shirts and dresses. A bread company in the UK adds a headlines to their packs every morning. The other technologies take too much preparation time. They are not eco-friendly also.
