3.0 TYPE AND DESIGN ELEMENTS<br />

3.1 Typography: Know the Print Process Capabilities<br />

Due to the nature of the flexographic process, text that prints positive will tend to fatten while text that is reversed out will<br />

tend to fill in, lose fine lines and serifs, and become plugged. Therefore, when selecting fonts, care and attention is critical.<br />

Tables 3.1a and 3.1b provide general guidelines by flexographic print segment. Because the minimum type size and rule<br />

width are print system dependent, the designer should confirm rule width and type style & size with the print provider.<br />

When attempting to increase the weight of a serif font, it is not always effective to use the bold, heavy, black, or ultra versions.<br />

When fonts are changed to a heavier version, verify the text did not reflow. Type can be stroked to increase its thickness, but<br />

the “counters” (holes in letters such as a, d, o, e and R) may fill in, so care must be used.<br />
