Brayer (roller)
Inking knife
For Clean Up:
Mineral spirits
Cloth shop rags
Paper towels
Nitrile gloves
After mixing the ink, use your inking knife to apply a small bead of
ink to the glass inking slab. The next step is to roll your brayer back and
forth, gradually spreading the ink to create a thin layer on the surface of the
glass. Make sure that before you use your brayer that it is clean of any
residue.

| Inking knives are available in a variety of widths. When inking a woodblock or woodcut, you only need to apply a very small amount of ink to the inking slab. |
Brayers are available in different durometer or hardness. For inking woodcuts, many people prefer a softer
brayer with a durometer of 20 to 25. The softer surface, in the opinion of
some, is more reliable in depositing ink onto wood surfaces which may have a
pronounced grain or texture.

If you have achieved the right consistency, the ink that you have rolled
out on the inking slab, will have a uniform shine with no dull spots or marks
on the surface. In spreading the ink, also note the sound that the brayer makes
as it rolls over the inked glass surface. If you have properly spread the ink, you will
hear a very subtle sound. On the other hand, if you hear a crackling sound, the
ink is likely too thick. Thick ink can
cause printing problems, because the excess will fill in the fine lines cut
into the woodblock and you will lose some of the detail in your print.

After rolling the ink to the right consistency, use the brayer to carefully
apply the ink to the surface of the wood panel. Coat the surface of the
woodblock, rolling the brayer in the direction of the grain. When first applying
ink, the wood will absorb some of it. So on the first application of ink, you should
recoat the surface a second time.

As you are coating the wood with ink, pay close attention to the
surface, inspecting it for any stray wood chips. Carefully remove these chips
as necessary using either tweezers or the point of a sewing needle.

After doing that, you should pull a test print. After inspecting the
print, make any needed corrections in cutting the woodblock. To
pull a good print, the ink must uniformly coat the entire surface of the
woodblock with a thin layer. After inking the woodcut, you are good to go.

| The materials used for the rolling cylinder of the brayer can vary in hardness. The hardness of the material is measured as its durometer. The hardness or durometer of brayers used for woodblock and linocut printing typically ranges from a soft material at about 20 or 25, to a hard surface of 60. |
