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 […]
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.
Measurement is the basis of process control. The measurement of dot area coverage or dot percentage is fundamental to define the characteristics of our printing system, to calculate compensations of tonal values for plate making and, finally, to control the production.In 2017, a new method for the calculation of dot area percentage was introduced. ISO
What are the correct units of measure to describe the engraving specifications of anilox rolls?I hope this short video serves to clarify this aspect with correct terminology.
A short video on the reasons why in flexography it is necessary to use specific angles for the halftone screens.
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
