Here is a print condition audit that initially revealed an insufficient quality level, scoring below 30%, and ended with a final score of 83% with satisfaction of both printer and final customer. The printer invested in 3 days of process calibration activities over 3 weeks time with the limitation of using the existing press setup […]

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,

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 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
What does “minimum dot” mean? Read More »
The term “round dot” refers to the screening algorithm that tends to draw round shaped dots. Let’s not forget, however, that the original digital file is made of square pixels. These pixels are the binary information that is sent to the laser to write the image: write / don’t write = on / off. Therefore,

One of the most frequent activities in prepress editing for flexography is the setup of run color control patches. Such targets may include different elements like a solid 100%, different tonal values and other elements like impression and slur patches. When using Adobe Illustrator for editing complex jobs featuring many colours, it might be useful
