The invisible enemy of flexography: the variability that no one measures

Why are two identical flexo print runs never truly identical?Many printing companies try to improve quality by tweaking on inks, anilox rollers, plates, or other machine components, but they overlook a much more insidious factor: process variability, or the dispersion of values over time.A process may seem correct but produce waste because it isn’t stable.Print […]

Color Management is NOT Prepress

Color Management for Flexography?Well, let’s start by saying that it is NOT prepress.Everything starts from the printing press and returns to the printing press…And you can find out the rest by watching my presentation at the FTA FQC/FIRST Tech Focus last September 27, 2024

Do you tolerate that blue?

Today my wife challenged me with 2 versions of a packaging that showed a brand color with -she said- visible differences: “But is this difference tolerable?” she asked.I must say that her color vision is probably not normal: she can often spot a difference when a normal human being would not see anything.So, I took

Why do you request such a high relief on your flexo plates?

Sometimes printers request that their flexo plates are made with an excessively high printing relief, with a deeper engraving than necessary.This can be a sign of something not working properly in the printing unit.Hear what happened recently when a flexo repro house called me on this topic…

No… There is no ratio between plate and anilox screencounts.

We often hear about a numerical ratio between the screencounts of the flexo plate and that of the anilox roll.In ancient times it was also said that it had to be an odd ratio, like 1:3, to avoid moirée.Then numbers like 1:5, 1:6, 1:7 arrived…There actually is a relationship but it’s not really based on

What screening are you talking about?

When referring to the screening of the flexo plate, it is possible to confuse whether it is the screening of halftones, which produces the tonal gradations, or the surface structure of the plate applied to improve the ink transfer and laydown.Let’s see what the differences are between these different screenings and how they are connected

Can you print a higher screencount on the same anilox roll?

Increasing print quality by printing a higher plate screencount is often requested.And one of the typical questions is “how far can I push it to print with the same anilox roll?”With this short video I touch some aspects to be considered.

Do you solve problems or make them not happen?

It is often thought that the skill of a printing press operator is linked to his ability to solve problems. It’s actually more important to make sure these problems don’t happen. And this is achieved with an in-depth knowledge of the variables and components that interact in the printing process.I covered this in the article
