Black (<strong>iGen</strong>3 ® only)<br />

• The Xerox <strong>iGen</strong>3 produces the most dense black with 100% K only.<br />

Adding C, M or Y to 100% K will generally lighten blacks. This means<br />

that Rich Blacks may not produce the results you normally expect with<br />

traditional printing.<br />

• When printing black on uncoated substrates, add a small amount of<br />

C, M or Y to improve uniformity and minimize paper texture. It may,<br />

however, produce a black slightly less dense than just 100% K<br />

only on an <strong>iGen</strong>3 press.<br />

• The <strong>iGen</strong>3 can produce a varnish effect by contrasting 100% K<br />

with graphic elements that are almost solid (e.g., 95-98% K).<br />

See last example below. Let your print provider know if you want<br />

to create this effect.<br />

• Black overprint is not usually recommended. Consult your<br />

print provider.<br />
