Do I really need a standard to print?

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. [...]

Best resolution for images in flexo?

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 [...]

What’s the best dot shape for flexo?

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?

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 [...]

Screen angles in flexography

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 [...]

What does “isolated dot” mean?

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 [...]

Slur: the sneaky enemy of print quality

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. The printed image [...]
