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, […]

Probably not, but you surely need an organised, consistent and repeatable printing system. If I look for a nut suitable for an M4 screw, I just have to look for an M4 nut to make sure I have the right nut. An organised and repeatable system has a better economic and quality yield. This is

This year I was honoured to be requested as a speaker during the recent Flexo Summit Latin America, organised by ProjetoPack in São Paulo, Brazil on May 22-23, that was announced to be the most interesting event for the flexographic industry in the region. And it really was! The idea was to share with the local

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,

Flexography will definitely benefit from latest ISO standards on Graphic technology: ISO/PAS 15339-1:2015 – Printing from digital data across multiple technologies – Part 1: Principles ISO/PAS 15339-2:2015 – Printing from digital data across multiple technologies – Part 2: Characterized reference printing conditions, CRPC1-CRPC7 ISO 17972-4:2018 – Colour data exchange format (CxF/X) – Part 4: Spot

Have you ever wondered why we need to use different screen angles in flexography? First of all we need to remember that we consider the screen angles when we look at the final printed product, so the parameters we set in the prepress/imaging workflow are meant to obtain the angles as described. Then we need

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

Description Causes Remedies Description Slur is characterised by the smearing of the printed image: the dots are distorted in printing direction, typically elongated, and exhibit an oval shape. This condition is caused by slippage at the point of contact and impression between the plate and the substrate and/or even the plate and the anilox roll.
