As sustainable development gains importance. Standards and goals are being set at a global level to reduce carbon emissions and ultimately reach net zero emissions. In the latest COP27 (Conference of the Parties), one of the world’s most significant summits on climate change, countries are coming together, reaching a consensus to combat climate change issues. As flexo printers, we can no longer stand on the sidelines. Actions must be taken starting with your own flexo press. There are many ways to increase efficiency and lower energy consumption on your flexo press. In this article, we will explore three different ways including 1. Selection of motor, 2. Drying method 3. Data monitoring.

Over time, consumers are becoming more conscious of environmental sustainability, the social impact and the transparency of a company’s governance. Therefore, flexo printers need to make the investments and to make the transformations necessary to keep up with this trend. There are many approaches to becoming an ESG orientated company. One approach is to establish a green water based flexo printing operation.

Rotary dryers can come in two types of airflow configurations. The co-current system and the counter current system. Co-current system is designed so that the airflow and material flow in the same direction. On the other hand, counter current system is designed so that the airflow and the material flow in the opposite direction. To decide which system to adopt will depend on the type of substrate, ink and coating solution used. In this article we will lay out the advantages and disadvantages of both systems for you to review.

Flexographic printing, coating process, lamination process…etc. Whatever the process may be, drying plays a crucial role in the success and failure of the end result. The drying process should be seen as three phases instead of one. The initial phase, the constant rate phase, and the falling rate phase. At each phase the drying substrate will behave differently, affecting your end result. Understanding the role of each phase will help you achieve a balance between efficiency, throughput, and cost control during the journey to create the desired product.

In general, as the press speed increases, the ink will dry faster on the anilox and plate. The reason is at higher speed, the air turbulence will increase, the shear force will increase, and more heat will be generated at the anilox and plate. To decrease the ink drying speed, the energy placed into ink drying will need to be reduced to compensate for the higher airflow and higher heat generation.

When choosing an anilox, should I go for an open cell or a closed cell system? The answer to the question depends on what you are working with (ink type, ink viscosity, plate LPI) and what you would like to achieve (printing, coating, half-tone, solid). In this article we will be looking into the characteristics of an open cell system and a closed cell system. To address issues such as ink spitting and pinholes and how to solve them from a cell system’s perspective. Furthermore, going into a few scenarios including high speed printing, UV ink application, special ink / coating enhancement, where certain cell designs may be recommended over the others.

Even though PE coated paper are recyclable, the recycling processes are time consuming and labor intensive, resulting in most PE coated paper to end up in landfills. According to BBC news, 99.75% of paper coffee cups are not recycled. If PE coated paper are non-recyclable from a cost perspective and causing environmental burden, why are PE coated paper still being adopted at a mass scale?....We will explore the benefit of PE coated paper that made them so popular on the market. As the market becomes more environmentally conscious, more environmentally friendly solutions have been developed to replace the long-standing PE coated paper...We will explore the substitute coating solutions and their production processes.

What does wide tension range Flexographic press imply? The different substrate will require different tension range during the printing process. Therefore, the wider the tension range of a Flexographic press means that the more materials the press can take on. On a KYMC press, a tension range of 25N to 350N is achievable. At this tension rage, many different materials can be printed. For instance, PP, BOPP, LDPE, CPP, HDPE, PET, paper…etc.

Reprint capability can make your life easier in today’s business environment. Let’s discuss why is that? Undeniable, Flexography practitioners will agree that production variations and uncertainty levels are much higher today than before. These are caused by the brand’s need to attract and fulfill the consumers' ever-changing appetites. Therefore, variations and uncertainties are here to stay. The only thing that you can do is to adapt. There are many ways to adapt. In this article, we will discuss how your Flexographic press can help you adapt through its reprint capability.

Visual printing refers to the presentation of the print. How well does the print come out visually in front of the audience? Does it serve its marketing purpose of appealing to the audience? On the other hand, functional printing is about the properties and functionalities delivered through the print. How well does it perform to carry out the actions that it is intended to? In this article, we will explore the differences between visual printing and functional printing from their applications and quality assessment methods. At the same time to discuss the scenarios and potential of combining visual printing and functional printing together.

So what is the opacity for the white ink laydown background? This is a common question that people ask when trying to identify the quality of the white ink laydown in Flexography. Opacity is definitely one of the metrics for measurement. However, it only tells part of the story. It is possible to have two prints with the same opacity reading but differs in print quality. The reason is that opacity alone does not measure the smoothness or uniformity of the ink laydown.

In any manufacturing process, a business evaluates cutting based on speed, accuracy, versatility, maintenance, and pricing. In general, laser die cutting is suitable for manufacturers that focus on short run orders with various customization requirements. The rotary die cutting is ideal for simple non-custom products in bulk. Let’s look into why that is so?
