In printing, all text in CD files must be converted to outlines to ensure print quality.

Some images come from Photoshop and contain embedded text in a combination of text and graphics. If this text isn’t converted to outlines, can it still be printed?

Printing typically uses CMYK, where each color represents one cylinder in the press. A sheet of paper must pass through four cylinders to achieve full color. PSD files can also be printed, but if the text is set in CMYK colors, issues may arise. Modern printing equipment can handle CMYK text reasonably well, but for smaller fonts, especially Songti typeface below 5pt, challenges emerge. Printing such fine text through four cylinders can be problematic; even a slight paper misalignment of 0.01mm could distort the text. For instance, CDR software’s default fine line thickness is 0.076mm, while printing equipment precision is 0.01mm. This discrepancy illustrates why using simpler, more straightforward colors is preferable for print accuracy.
