Optimizing Solids

Image
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. Density values for different levels of reflectance.  Source: A Guide to Understanding Graphic  Arts Densitometry by X Right To optimize solids we must first review the basics...what is density, or to be more accurate, reflection density?  According to the Flexographic Image Reproduction Standards ...

Liquid Photopolymer: A Seasoned Technology for Today's Corrugated Printing

Image
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...

Let's Talk About Flexo Plates

Image
Flexographic (aka Flexo) printing quality rivals the quality of both offset and gravure. Is this the first time you heard this? Probably not! If you are reading this blog you are likely aware flexo is the #1 print method for flexible packaging in both the United States and Europe. The evolution of flexo from a somewhat viable option to the #1 choice is multifaceted with advancements across the entire printing process. One major factor is that flexo printers are optimizing their processes with flat-top dot photopolymer printing plate solutions. It’s been said, to do a job correctly, first you must have the right tools. In today’s flexo printing market, having the right plate (the tool) can make the job easier, more consistent, and ultimately more profitable. Flat-Top Dots The packaging market consists of four major market segments: flexible, tag & label, folding carton, and corrugated. MacDermid Graphics Solutions (MGS) has an out of the box, flat-top dot solution for all markets...
