Offset and flexo printing
Offset and flexo printing are excellent techniques for long print runs as they keep costs down. However, on a market that is shifting towards increased customisation and minimal lead times, these traditional methods are no longer sufficient.
Unless you’re running large print volumes, offset and flexo work simply aren't cost-efficient. Small print runs are now frequent and the only way to make them profitable is to add an industrial digital printer to your printing equipment.
Digital printing for cardboard finishing
Cardboard is a sustainable material and for this reason many industries prefer it to plastic. This preference largely occurs in the packaging sector, and runs parallel to the increasing use of eco-sustainable products in the food, cosmetics and nutraceutical sectors. Some cardboard products - such as puzzles, disposable eyeglasses and place cards - also need to be decorated. Industrial digital printing is a technology that allows customisation of these products, even where volumes are limited, and without any proportional increase in costs.
Benefits of digital printing
Turning cardboard into a box, a display or another form of packaging or any other product requires a number of processes. In addition to creasing, die-cutting and gluing, printing is also necessary. Industrial digital printing provides huge benefits when print runs are limited or customisation is required. Let’s take a look at these benefits:
4-colour (up to 7-colour) printing is possible with 2 degrees of nozzle density: 400 and 600 npi; resolution in the cardboard advancement direction from 800 to 1200 dpi depending on print speed.
Reproduce any digital or digitalised image (e.g. a puzzle) to print one-off data or content on cardboard displays or packaging.
Minimal set-up times, flexibility and the simplicity of the process that takes you from print file to printed product reduce time to market.
Industrial digital printers fit seamlessly into existing production lines regardless of the equipment upstream or downstream.

Firstly, this does not mean “rapid prototyping”. It means creating a superficial 3D effect, a texture.
Yes, it is possible.
Achieved digitally on single-pass and multi-pass printers, there are 3 methods we advise to obtain different characteristics, all of which create a 3D effect. Depending on the end usage of the finished product, we would recommend one of these methods.
The first two methods are suitable for single-pass lines; both are "subtractive methods" (meaning that the "grooves" are obtained displacing/removing part of the high-resistant top-coat); the two methods differs for the way the grooves are obtained, one by displacing/rejecting the high-resistant top-coating, the other removing the high-resistant topcoating by brushing with suitable brushes the coating in the "to-be grooves" areas.
The third method is suitable for multi-pass machines and is an "additive method" (meaning that the "reliefs" are obtained by adding a specific ink, like in the additive manufacturing processes).
This can be achieved by implementing the following activities:
- Check hardware set-up daily: align the print heads, clean the nozzles.
- Check software set-up regularly: ensure nozzle compensation and shade uniformity across the conveyor.
- Ensure correct workflow and follow it strictly at all times: coating process control, colour profiling, image management, raster image processing (RIP).
- Define and perform Print Quality Assessment & Maintenance daily.
- Handling large volumes. This technique is not for mass production.
- Economies of scale. Unit cost does not drop in line with higher volumes.
- Learning curve. Many end-users are at the start of the learning curve and need to develop some skills and knowledge to exploit the technologies. We can support you.
