Troubleshoot image quality problems
This chapter explains how to address typical image quality problems.
Ensuring high-quality documents and images
●
Ensure that all text is converted to outlines (not bitmaps) or the fonts are included with the artwork
files.
●
All line art should be in vector form (not bitmap) for good scalability and reproduction.
● Large blocks of solid colors can show banding more obviously than smaller areas of color or
photographic images.
● Ensure that photographic images are sized appropriately for the final output resolution. For
example, don't try to scale a 300x200 pixel image copied from a web site to fit a 1 x 2 m (4 x 8 ft)
poster.
● Select photographic images with evenly-balanced contrast and color saturation. Subtle shadow
areas or “blown-out” highlights are difficult to print well).
● In the application program or the RIP, use the ICC color profiles provided by your RIP manufacturer
that are tuned for the ink set and media you will be using. Color must be managed in either the
application or RIP, never in both.
