How often can you say a technology from the 1960s remains competitive in nearly the same form today? One technology is liquid photopolymer for direct print corrugated applications in flexography. Over the past 50+ years, we have witnessed the introduction of digital platemaking and the continued evolution of water wash technology for sheet photopolymers. Each of these areas competes with liquid platemaking yet, despite these competitive pressures, liquid technology remains alive and well. While liquid continues to evolve through imaging innovations and enhanced processing equipment, it maintains its fundamental characteristics as well as its ecological and economic strengths. Along with the digital revolution, and the equally demanding sustainable revolution returned focus to liquid's unique capabilities. Working for MacDermid Graphics Solutions, I have the unique vantage point of innovating in multiple plate technologies such as analog and digital platemaking, as well as solvent...

Preface As we navigate these times during the COVID-19 pandemic, MacDermid Graphics Solutions is proud of our global team for following local health safety guidelines while continuing to support our company and customers. Ivan Rozo, Business Development Manager, MGS Latin America, wrote this blog to reflect on the changes and challenges that we are all experiencing in the packaging supply chain. With this article, Ivan wants to thank our LATAM team; he and the rest of MacDermid stand behind them as they work to stay on top of the current situation.   Image 1. Planning and Solutions To start, we must travel back in time to the fall of 2019...businesses were budgeting and organizing sales plans for 2020. Having a string of continuous growth, it seemed logical to project a new year with bigger goals and more significant challenges. For MacDermid, the differentiation in our value equation always seeks to provide operational advantages that allow us to solve busin...

Marketing messaging today can be overwhelming, especially with flexo photopolymer plates  and the word “clean.” You hear terms like clean print, clean plate, prints clean, anti-fill, and more. It is safe to say all plate manufacturers want you to achieve cleaner print, and there are only so many ways to say it or even show it. You may have even seen our competitors using a stock photo we too have used to advertise our plates and technology (awkward). While we won’t mention our competitors by name, we all know improving plate cleanliness on press is a big benefit for flexo printing, but what does the “clean” really mean? Clean - The MacDermid Plate Definition First, if cleanliness on press must be improved, that means something must be dirty, right? “Dirty” print is a multi-factored issue and can be impacted by more than just the plate. Our friends at All Printing Resources (APR) did a great job explaining dirty print in their three-part blog post “Understanding Common...

Flexography is a printing process used for a large number of substrates and applications, as such the process colors can differ based on the pigments based on in their properties. Although there are color specifications, there is no general norm for density values leaving a number of open questions... What is the correct density for a printed job? Why do we find different values from company to company? Who is right? The reality is that in recent years a popular belief has emerged: the higher the density, the better the result. Ideally, an attainable, repeatable, and consistent standard should be established maintaining a correlation closest to the color proof. Image 1.

Flexographic printing is continuously evolving, and the platemaking process is seeing this exponentially. Platemaking is evolving not only in the development of new and innovative materials but also in the technological improvements of imaging and processing equipment. Together these make a more efficient and consistent workflow to deliver high-quality plate that can consistently reproduce the information of a digital file in its finished structure. All of us have been familiarizing ourselves with terms such as high definition, high resolution, surface screening pattern, and flat-top dot, among others. The reality is that ALL suppliers in this field have achieved a synergy, bringing about a complete revolution making the flexo printing process more competitive compared to other technologies such as rotogravure and offset. However, in an environment that tends to become more automated, there are still uncertainties in the manufacture of the plates and even returns of the finished prod...
