The Influence and Use of Colours in Printing Packaging for the Food Industry

The topic of the diploma thesis is the influence of colours in the food industry, which encompasses everything from the design idea to the actual product on shop shelves. Colours and packaging are the observer's first contact with the product and can either convince or deter them from the very beginning. Throughout the entire history of humankind, certain stigmas, associations and views connected with colours have developed. For one of the designs, they also created colour separation and a simulation of the final coating – matt varnish.

Problem

The topic of the diploma thesis is the influence of colours in the food industry, which encompasses everything from the design idea to the actual product on shop shelves. Colours and packaging are the observer's first contact with the product and can either convince or deter them from the very beginning. In the theoretical part, we touch upon the basics of colours and how we perceive them.

We define their meaning, ** symbolism** and ** properties**, whilst placing emphasis on their effect in connection with food. We continue by determining the importance of the correct use of colours, so that our designs do not communicate incorrect information to observers, as this can quickly deter them from purchasing the product. In order to find out what each colour represents and symbolises, they had to go back in history.

Solution and Method

Throughout the entire history of humankind, certain stigmas, associations and views connected with colours have developed. This is the first thing we see. We connect colour with emotions.

Later, colours began to be interpreted with the help of various systems, such as Cielab, for example. In systems, we mark the exact desired colour numerically or with a point, and thus ensure that the colour is the same for all users. In addition to colour systems, it is also necessary to understand colour models such as ** RGB** and ** CMYK**, which are very important in printing.

They constitute the raster and all printing techniques, technological processes and pre-press processes are based on it. They will examine flexographic printing in more detail, which is most commonly used in printing for the food industry and on flexible packaging. It is divided into surface and laminated printing.

After the theoretical part, we move on to the practical part; to the production of colours and all the factors in production that we must pay attention to. From an ecological perspective, we also add how to properly store and reuse colours, new printing techniques and types of colours that are more environmentally friendly and cause fewer emissions. In addition to process colours, many Pantones are used and produced in production, which are mixed and measured with the help of ** Pantone** ** scales**.

For the research part, they created a survey about the influence of colours on customers in shops. After all the collected information, the theoretical and practical parts, they created an additional diploma product, which is the design of a logo, several ** sleeve** sleeves for ** seltzer** beer cans and the corresponding promotional materials, such as various ** mockups**, business cards and social media advertisements.

Results

For one of the designs, they also created colour separation and a simulation of the final coating – matt varnish.
