Good Morning !!
My name is Bonaldi Luca , I have aa Degree in Computer Science at the State University of Milan,
and devolop software for vision systems with color camera , especially in the field of flexo printing machines.
Unfortunately, the company I worked is failed, so I want to propose my projects to other interested companies.
I hope not to have the wrong site administrator since I do not speak German!
The algorithm allows the automatic register for theoretically infinite numbers of colors, develop C \ C + + Language (Compiler Borland Builder, Microsoft C \ C + + and S.O Unix ,Windows) .
Having developed the software alone, it is possible to change based on drill specific needs of the printer or to the machine on which you install !
As a first project I want to show an Automatic Control Registry for printing machine (flexo, offset,rotogravure ecc) https://www.youtube.com/watch?v=OFBQ4lL7pEs.
For 10 colors area is about 10mm * 10mm and for 20 colors area is about 15*15 mm considering the axial and conconferenziali ± 2 mm displacements of the cylinders .
The camera does not need to be positioned perfectly ortogolale compared to printing , since even a tenth of a degree implies errors on the calculation of the values find .
In theory could be at 45 ° to the direction of printing.
Obviously it is possible to put a color registers at a time, during the start, and during the production are controlled all the colors in real time.
Within this project, other options have been included, for example, the conversion from RGB color printing from the camera, in CMYK, Lab and XYZ, to alert the operator may lack or excess of one color.
For a colorimeter in line for example, the idea is to take an arithmetic average of the colors that are used for the Graphism the Registry control to alert the operator if it occurs the lack of a color during printing
thank you for giving me this opportunity

Good Morning !!
