Environment:

Module: github.com/pdfcpu/pdfcpu v0.11.0
Platform: MacOS
Go version: go1.24.3

Case：

When i validate the file badcase.pdf attached below, it seems my file badcase.pdf is invalid。However, i can it open with Adobe and WPS office.
So maybe there is a bug here like #1194, i guess.

Commands && error output:

$ pdfcpu val badcase.pdf
validating(mode=relaxed) badcase.pdf ...
validation error (obj#:54): dict=Ink required entry=InkList missing
