All of these modern Italian engravers appear to be working with computer-driven, or at least mechanized equipment to do their work.
Does anyone here at SCF known whether or not this is correct? |

Not sure about the method used, but they all somehow look "wrong" to me. Perhaps it's a specific style that has been adopted, but I am not a fan! GLENN |

The stamps in this Italian Artistic and Cultural Heritage series are produced in rotocalco (rotogravure), a printing process by which the paper is rolled through intaglio cylinders. Several other stamps (such as the 2014 Emperor Augustus stamp shown below) are produced in Calcografia e rotocalco (calcography and rotogravure).  |

Thanks KuoLC5310. That is quite informative as regards the printing.
The actual engraving work is the point of my inquiry. It lacks the subtleties of the artist's hand, i.e., it looks quite mechanical and "leaves me cold". |

bookbndrbob: Thank you for your comment. These stamps are indeed distinctly different from traditional intaglio stamps. I found an article Gravure Stamp Cylinders by Glenn H. Morgan: https://www.ohiogt.com/doc/articles...ts%201-3.pdfI will share new information when I find it. I also welcome comments from SCF members.

florian: Your information and comments are greatly appreciated. Confusion can occur due to errors in catalogues.
Below I present translation from one article in your list, to summarize the printing techniques of modern Italian stamps.
Today the two most used printing methods for the Italian stamps are chalcography and rotogravure with very fine net.
Calcography
In the calcography the matrix is engraved with a burin. The ink is applied to the whole table and then cleaned with a blade; the excess ink is removed with the exception of the filtered part in the cavities of the incision. Once the paper dampened on the plate is pressed, the ink transfers, leaving a characteristic relief, more or less accentuated, which is clearly visible in grazing light. In some cases, if the paper is not too thick, it is also possible to see the respective grooves on the verso.
Rotogravure
The rotogravure can be considered an evolution of the chalcography; the difference lies in the method used to create the grooves of the matrix: no longer engraved manually but obtained with an automated process. The drawing to be printed is transferred to the surface of the cylinder using a screen made up of many small dots. Subjected to a light beam, the mesh transmits the points to the cylinder which, thanks to particular chemical substances, is dug in correspondence with the illuminated parts. The greater the light reaching the cylinder, the deeper the recess becomes, creating a greater inking. The transfer method to the card is then the same as the calcography.

Thanks Florian and KuoLC5310. This information really gets to the point. The "Artistic and Cultural Heritage" stamps are printed by rotogravure.
So, "(the) grooves (are) no longer engraved manually but obtained with an automated process." It appears to be a mechanized, or computer-driven, photo etching process applied to the steel cylinder. The original artwork could have been done in any number of ways.
I guess the cold, robotic look is intentional.
