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…
Why do you request such a high relief on your flexo plates? Read More »
Have you ever experienced any troubles when printing in flexo? Here is a list of things you should avoid when approaching flexography in order to prevent from troubles in production.

Surface texturing of flexographic plates is nowadays widely used to improve the ink laydown when using latest flat-top platemaking technologies.The settings for such surface micro screening are carefully evaluated during the optimization phase of system calibration and they shall not be changed for that printing condition.Using wrong settings will cause not only the solids to

I’m really excited and looking forward to being in Bruxelles tomorrow at Labelexpo Europe 2019.This will be my personal 30 years anniversary edition, celebrating my 30 years in the industry as well. In 1989 I was just back to Italy, after almost 3 years at the School of Media Development and Graphic Arts in Kampala,

What is the best resolution for images to be printed in flexography? Well, it depends first of all on the distance that the printed product will be looked at by the viewer: this will determine the suitable linescreen that the image will have on the printed product. A general guideline for AM screening defines a

There are different dot shapes for screening: round, square, euclidean, elliptical, … which one is the best for flexography? (*) When choosing the dot shape for plate screening, it is important to consider the characteristics of the different geometries and their influence on the printed result. When the plate is inked by the anilox roll and

How many resolutions do we need to know in flexography?There are four important information related to resolution within the flexo workflow. 1# The resolution of the anilox roll, or its line-screen or cell-count, that is the number of cells engraved on the surface by linear unit of measure. We express it, in the metric system,

The information about the size (typically the diameter) of the minimum isolated dot refers to the characteristics of the plate and it is normally completed with the term positive and/or negative. Example: Minimum positive isolated dot: 100 µm Minimum negative isolated dot: 50 µm The minimum isolated dot size indicates what is the ability of

The information about minimum dot indicates what is the size of the minimum printing dot that appears on the plate. This size is normally expressed in microns (µm), or, less commonly, as a percentage of a given linescreen, and it is set as a threshold in plate imaging to obtain such size on the finished
