Relief Printing

Step 1: Define block printing. Block printing is a form of relief printing where the printing surface is a block from which non-image areas are removed. Ink is applied to the raised surface and then transferred to paper.
Step 2: Evaluate the given methods.

(B) Wood cut: This is a classic block printing method using a block of wood.
(C) Lino cut: This uses a block of linoleum and is another primary example of block printing.
(A) Collograph: This involves creating a collage on a plate; it can be printed as relief but is not typically called block printing.
(D) Oleograph: This is a type of lithographic print, not a block print.
Therefore, the clear examples of block printing methods are Wood cut and Lino cut.
