The Resins Remain Behind We have hand cleaned anilox rolls using stainless steel brushes and primarily caustic chemicals, ultrasonic, and media blasting [which can limits some line counts on anilox rolls based on the particulate size of the media]. Most recently we have seen high-pressure solution wash systems that use detergents, chemicals, and water. The … Read More...

A Bent Journal Translates to Poor Registration The above statement is what many of us simplify that TIR has an adverse effect on print registration. However, many of today's flexographic printing presses don't even use print cylinders with journals. TIR can be the root cause of different print defects based on where that compromised surface … Read More...
Last week's APR Technical Screening Summit turned out to be a great event! Our attendance reflected representatives from all facets of the print workflow—from prepress into the pressroom. Presentations touched on key variables in the production process that impact screening and print quality decisions and capabilities. Those attending brought up fantastic questions and discussion points. … Read More...
PrimeBlade 900 Nano PrimeBlade® Sweden, along with their partners, have developed a Nano technology to treat and produce different steel qualities, allowing them to optimize the properties and performance of the steel. The 900 Nano Series doctor blades are produced with the latest Nano technology without ceramic or nickel coatings being used today in long … Read More...
Today's Anilox Roll Cleaning Currently, and for the past several years, we have used four primary means of cleaning anilox rolls. We have hand cleaned using stainless steel brushes and primarily caustic chemicals, ultrasonic, media blasting which limits certain line counts on anilox rolls based on the particulate size of the media. Most recently we … Read More...
Struggling with printing pleasing highlights? Using these tips, your highlight issues can fade to zero! Prepress & Software Your press can only print as good as the artwork it’s given, so it’s only fitting that prepress plays a key role in improving highlight quality. While there are some tricks to provide an illusion of smooth … Read More...
While participating in a new press characterization, the customer reported they have been struggling with is variable SID (Solid Ink Density) across the web, however DOT gain is very consistent side to side. What this tells me is that while there may be parallelism between the rollers, i.e. anilox, plate sleeve, and CI (central impression … Read More...
Ink Density, A Universal Problem I can't imagine asking a printer if they ever struggle with achieving color or solid ink density (SID) during a press set up, and they reply with a "no". They would probably be much more likely to roll their eyes and asked me if that was a rhetorical question. The … Read More...
Viscosity and surface tension are two physical characteristics of liquid. Viscosity is simply the measurement of how resistant to flow a liquid is, while surface tension is defined as the resistance a surface to liquid penetration. Viscosity and surface tension are affected by temperature changes. Understanding and controlling ink viscosity remains one of the most significant variables and flexo printing process. … Read More...
The flexographic printing process is inherently tough on small type. Press settings, anilox selection, artwork, and mounting tape all play a role in how small type is reproduced on the substrate. Accurate and legible printing of small type is especially critical for applications such as pharmaceuticals and food packaging. In this blog post, we'll take a look … Read More...
