I would like to add 2 types of figures in my document (with different counters)
- Figures
- Plates (if general, would be possible to differentiate between B&W, Color plates...)
I don't understand which environment I have to customize (figures? refs? labels?).
Reason: All drawings should be named fig. XX and are in the text. Photos should be placed at the end and referenced as pl. XX. [For curiosity] it would be nice to distinguish B&W photos pl. XX from color c. pl. XX.
An example of rendered text could be:
From the diagram (fig. 1, p. 1), the X-Ray imagery (pl. 1, p. 32)
or the colored tomography (c. pl. 1, p. 104), we deduce that ....
fig. 1, pl. 1 and c. pl. 1 are three different images included with
\begin{figure}
\includegraphics[width=10mm]{fig_1}
\label{fig_1}
\end{figure}
\begin{figure}
\includegraphics[width=10mm]{pl_1}
\label{pl_1}
\end{figure}
\begin{figure}
\includegraphics[width=10mm]{c_pl_1}
\label{c_pl_1}
\end{figure}
I use xelatex and the packages varioref, hyperref, cleveref in this order (as specified in cleverref manual, 12.1, p. 23). My document use different languages (English, French, German) but all the references should be "fig/pl." (i.e. no translation into "Abb.").

\caption, correct would be\caption{<text>\label{fig_1}}for example. – Skillmon Sep 17 '20 at 09:19plate, and theplatecounter should be separate from and independent of thefigurecounter. (b) Theplatefloat type may need to consist of two subtypes, one for B&W images, the other for color images. (c) Cross-references to these objects should use the prefixesfig.andpl., repectively. Please advise if I missed something. – Mico Sep 17 '20 at 09:20
