원문 - 영어 - Woodblocks

The print would be passed on to blockcarvers who, using chisels, would carve a series of woodblocks—first, a "key block" showing the outlines of the print, and then one block for each color to be printed - often 15 or more blocks were required.
When the blocks were complete, printers would apply ink using brushes. Laying a sheet of paper face down on top of the block, the printer rubbed the ink onto [handmade] paper using a round, flat pad, called a "baren".
