What is digital printing?
Digital printing is a technique for reproducing images from computer data from a computer, tablet or smartphone. This data is sent immediately in a continuous flow to the printer. This is the technique we use most commonly at Alpilles Automation thanks to our Alex range of digital printing machines. This flexible and fast process is used very often by professionals and individuals. To perform digital printing, basically you need a printer and a computer.
This technique is used for documents or objects, from small quantities to very large ones. It can used to meet very tight deadlines.
Digital printing has three main characteristics:
- The image can be printed directly on to the substrate,
- The image can be changed for each edition, allowing for texts and illustrations to be replaced,
- Printing can be performed without interrupting digital data, from the computer to the digital printing machine.
During digital printing, the ink is applied directly on to the substrate. The computer controls this application. This technique can be used on a very large variety of materials.
What is inkjet digital printing ?
Digital printing entails using an inkjet to mark a digital file, i.e. to reproduce it identically on an object. To do this, it must first be broken into pixels, then each pixel is split into five main colours: White, Cyan, Magenta, Yellow and Black. All other colours can be made by mixing the four primary colours (the CMYK colour model). White is used either as a colour or as a sub-layer (to print on to an object that would not be white in order to respect the colour scheme sought, i.e. the file’s one).
Digital printing applies mainly in industry and graphic arts. Alpilles Automation is a specialist in the first category.
Digital printing covers two families:
- Continuous inket is used very commonly for the traceability of objects but it does not produce high quality resolution (around 75 dpi on average),
- Drop On Demand (DOD) entails printing with drops on request. That means there is no continuous propulsion, rather ink drops are deposited only at precise times and places as needed and in the amount required. This technique is far more accurate, much faster and produces a higher quality resolution (on average between 360 and 1480 dpi). This is the technique we use at Alpilles Automation so as to guarantee a very high-quality result and a high to very high printing speed.
In what areas is it used ?
Digital printing can be applied in various areas and on any type of paper, cardboard and a host of other materials, including plastic, textiles or canvass. Digital printing is a way of printing easily on practically all materials, even glass, plastic, metals, leather and wood, for small or large personalised print runs.
What are the benefits of digital printing ?
Digital printing offers a better print quality (High Definition) in record time and can print directly on to the material without an overlayer, giving a quality and aesthetically pleasing result. Moreover, there are no limits in terms of colours. The digital printing printing machine for all materials is ideal for printing small or large quantities.
