Even in times of digitalization, printed information has not disappeared from everyday life. Newspapers and magazines, books, packaging and various written documents continue to be produced in large quantities. At the same time, the pressure on industry and research to make production processes more resource-efficient is growing.
Papermaking, chemical printing inks and energy-intensive machinery can cause significant environmental impacts. This is precisely where numerous research projects and institutes like this focus Research institute for the printing and media industry to. You investigate how materials, processes and circulation systems in the printing sector can be changed to save resources and reduce emissions.
Researchers not only look at the finished printed product, but also the entire life cycle. Every step is analyzed, from the composition of the printing ink through the printing process to the recycling of the paper fibers. The aim is to design printing processes in such a way that they use as few raw materials as possible and that materials can be reused after use.
New materials are changing printing technology
A central area of research concerns the chemical composition of printing inks and toners. Classic printing inks consist of pigments, binders, additives and solvents. These components ensure that paint adheres, dries and remains permanently stable. At the same time, solvents or certain additives can cause environmental problems. That’s why chemists and materials scientists are working on developing new formulations.
Receive special attention Colors based on renewable raw materials. Vegetable oils can, for example, replace mineral oil-based components. Also water based inks are becoming increasingly important because they contain significantly fewer volatile solvents. Such approaches reduce pollutants and sometimes also make the recycling process easier.
In addition, researchers are investigating how binders and pigments can be combined in such a way that printing inks can later be more easily removed from paper fibers. This point is crucial for paper recycling. In so-called deinking, printing inks are removed from waste paper using mechanical and chemical processes in order to produce new paper. This process is the key to ensuring that printed paper can be reused at all.
Another approach is to produce the paper in such a way that no further pigments are necessary. About ten years ago, an international team of researchers developed paper that contains dyes that only become visible upon contact with water. If you no longer need the printed matter, it can be easily erased by briefly heating it – the paper can then be printed again.
The printing process as a scientific field of investigation
In addition to the materials themselves, the printing process is also the focus of research. Printing machines work at high speeds, consume energy and produce waste, for example through waste or cleaning processes. Engineers are therefore analyzing how these processes can be optimized.
Digital printing technologies now enable much more precise control of the amount of ink. This means that only as much material is used as is actually needed. At the same time, modern control systems can reduce the energy consumption of printing machines. Process optimizations help to minimize paper losses and reduce emissions from production and cleaning.
The use of suitable paints, varnishes and adhesives also plays a role. They must not hinder the recycling process. In print production, attention is therefore increasingly being paid to ensuring that the materials used are as recyclable as possible.
Paper in circulation
The biggest lever for more sustainable printing processes lies in the use of paper. Although paper is a renewable raw material, its production requires large amounts of energy, water and wood. Recycled paper can significantly reduce this burden. Studies show that up to 60 percent energy and around 70 percent water can be saved when producing recycled paper compared to paper made from fresh wood fibers.
However, for recycling to work, several conditions must be met. The material must be sorted, printing inks must be able to be removed from the fibers and the fibers must not be damaged too much during the preparation process. That’s why researchers are working intensively on the interaction between printing ink and paper fiber.
This topic is also becoming increasingly important in industrial research. Networks of companies and scientific institutes are developing new technologies to make paper production more energy efficient and climate-neutral in the long term. An example is the so-called Paper model factoryin which new processes for significantly lower-energy production are being tested.
In this larger context, the everyday life of users also comes into greater focus. Printers, paper and consumables are used every day in offices, universities or private homes. How these resources are used influences the entire material cycle. It is therefore also about how sustainable printing can be implemented practically by consciously choosing materials and organizing printing processes efficiently.
New technologies from materials research
Completely new applications are currently emerging in parallel to the classic printing industry. In materials science, for example, conductive inks are being developed that can be used to directly print electronic components. Such processes enable flexible sensors, intelligent packaging or wearable electronics. Some research projects are already working on inks that can be dismantled and reused after use.
3D printing also shows how closely printing technology and materials research are now connected. New printing materials are created here, some of which are made from recycled raw materials. At the same time, scientists are investigating how production leftovers can be converted directly into new printing materials. In the 4D printing Movable and changeable objects are produced, for example flat kits, which at a later point in time unfold in a controlled manner, for example into three-dimensional objects, or which can change their shape depending on external influences.
These developments show that the term printing today encompasses much more than traditional paper products. Research is moving towards a comprehensive materials system in which printing processes, chemical processes and circular economy are linked.
A technological change in the background
Change in the printing industry often takes place in the background. For readers or users, the end product usually remains the same. A book still looks like a book, a document remains a document. But behind these everyday products, the technology is changing step by step.
New printing inks, more efficient machines and better recycling processes help to conserve resources. At the same time, research shows that sustainable printing processes do not only arise from less use, but above all through wise choice of materials, optimized production chains and functioning circulation systems.
The development of modern printing technologies is an example of how classic industries can be rethought through scientific innovations.
