Hi Leo, Acrobat for Linux is available (although the version is too old) at ftp://ftp.adobe.com/pub/adobe/reader/unix/9.x/9.5.5/enu/. Acrobat isn’t able to deal with the signature annotation and with the >> Sorry, objects is a very special term in PDF parlance. It has nothing >> to do with signatures. Here is a description: https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#search=4.35 (link should work with Firefox). But you might check yourself with the following sample: \setuppapersize[A10, landscape] \setuplayout[page] \setupinteraction[state=start] \starttext \setupfield[sl][horizontal] [frame=on, width=\textwidth, height=\textheight] \definefield[x][signature][sl] \field[x] \stoptext The attached certificate has the password 123456. Only mupdf-gl sees the signature annotation after signing it. Acrobat, Evince, Okular and xpdf cannot deal with the signature. https://validator.docusign.com/ gives a warning: This document doesn't have any digital signatures. I hope it might help, Pablo -- http://www.ousia.tk
