Dry point is an intaglio printmaking; an image is incised into a plate with a hard-pointed needle of sharp metal. You have to be more careful inking up than in other techniques, too much pressure when applying the ink and cleaning the plate will ruin the image.
Lino printing is a variant of woodcutting. A sheet of hard or soft cut lino is cut into using specialises tools. It is inked with a roller then impresses onto paper or fabric.
