<p>[QUOTE=&quot;Debora, post: 9725642, member: 1476&quot;]Halftone printing uses four colors -- cyan, magenta, yellow, and black -- in combination as needed to create other colors.&nbsp; Black will often appear as solid black because it doesn&#039;t need the addition of another color.&nbsp; A genuine period map would be hand-colored and those &quot;dots&quot; wouldn&#039;t be visible.&nbsp; </p><p><br /></p><p>Debora[/QUOTE]</p><p><br /></p>
