专业浮雕印章

Question

与我之前的问题相关邮票的特别废止（即取消）和采用意大利格式和时区的两行日期时间我创建了另一个 MWE，以便拥有一些不同的选择和更专业的音色。

\documentclass[12pt,margin=3mm,italian]{standalone}
\usepackage{newtxtext}
\usepackage[dvipsnames]{xcolor}
\usepackage{tikz}
\usepackage[useregional=numeric,showseconds=true,showzone=false]{datetime2}
\usepackage{fontawesome5}

\begin{document}
\begin{tikzpicture}
\draw (0,0) node[minimum size=4cm,
                 draw=black,
                 circle,
                 line width=.5mm, 
                 text width=3cm,
                 align=center] 
                 {\large \bfseries \mbox{\DTMtoday} \DTMcurrenttime};
\draw [black,line width=.35mm] (0,0) circle[radius=1.75cm];
                 {\large \bfseries \mbox{\DTMtoday} \DTMcurrenttime};            
\node at (0,1) (A) {\textcolor{Green}{\large Visto}};
\node at (0,-1) (B) {\small \textsc{Non approvato}};
\end{tikzpicture}
\end{document}

我会

浮雕的圆周，删除中间部分的“non approvato”和“visto”，并将其放在两个圆周之间。

在https://tex.stackexchange.com/a/545988/87678，可能会得到与图片略微相似的效果。您可以进一步调整各种设置以符合您的喜好。

但是编译起来相当慢！使用 ImageMagick 编写脚本可能更快、更简单、更美观。
