Made this simple layout for printing 85 mm/55 mm sized business cards on an A4 size paper.

Not entirely sure if the trim marks could make a good use.
Or how the trimming is done in general -by trimming a side, all marks on the other side are cut off.

Anyone with some experience in that?

You can slove that problem by setting cut marks between the gaps inside the page.
