what is any printmaking technique in which the printing plate or matrix is carved with carving tools so that the areas that are not meant to be printed are below the surface of the matrix?

usually, crying is seen as unprofessional, but nowadays, most employers or fellow employees will be understanding of your distress and they will usually be authentic.   but you should try to hold it in or say that you need a break and wait until after the meeting when you've had a chance to calm down to discuss the issue that is going on. hope that !
