I am not sure which would be the appropriate forum for this, but I have one "question" that I thinking about a lot in recent months and that I would like opinions and experiences from other printers.

How do you present your prints made with historic / alternative printing techniques - platinotypes, kallitypes, Van Dykes etc.where you hand coat your emulsion?

Do you mask the edges before coating so that the image has "clean" borders?
Do you mask the edges when exposing (using rubylith or similar)?
Do you cover the black/dark edges on the print when matting? (e.g. cutting the window in the mat-borad so that only the image area is visible?)
Do you cut the window in the mat-board so that the borders are visible and presented as a part of the image?
