One of the Marketing Managers at DuPont Packaging Graphics in the US described in one of his articles – based on the surveys of DuPont – what it was that customers and printers needed the most. The results definitely showed that it was production efficiency and compliance with the quality requirements. Naturally, this can only be provided if stable and high-quality printing forms are used. This paper explores the solution to a genuine problem – to find an answer on how to obtain the best results of printing on colored kraft paper using flexographic printing.
The choice of the topic was inspired by the fact that in Western Europe – and increasingly in Central Europe as well – food products made from organic or natural raw materials, as well as artisan products are often packaged in plain brown or white paper without prints, or in printed, colored kraft paper packaging material.
Each day we are also faced with special tasks: finding the optimal solution – making the right printing plate – for printing on a difficult material. Due to its structure, brown kraft paper is included in the more problematic topics.
We were inspired by the possibilities and the challenges, with the purpose of examining the responses (in respect of printing parameters) of printing plates’s surface roughening structures created with the use of the modern processes, and at the same time focusing on finding the best printing results when flexo printing on this material – kraft paper – that is increasingly popular in the packaging industry.
This article examines the various possibilities of achieving surface roughness when making the printing plates, and then, based on the results of our examination, we intend to show the methods for achieving the best printing results on brown kraft paper.
