Bleeding

Description

Color inks, printed side by side, mix together at the border. Also occurs at areaĆfill borders

with a high color saturation.

Causes

The ink is not properly absorbed by the media and spreads from its original position. Media

types affected are bonds.

Corrective Actions

Plot in an interlaced print mode (Best), thus increasing the number of passes over the media.

Set the lightness to lighter" to reduce the amount of ink used.

Feathering

Description

Ink spreads along the media fibers, affecting the edge roughness of the lines and text.

Causes

The medias does not control the dot growth. The affected media types are:

D Bonds.
D Natural tracing paper.
D Vellum.
D Translucent bond.

Some third party media types have unacceptable results.

Too large a drop volume increases the severity of the problem.

Corrective Actions

Plot in an interlaced print mode (Best), thus increasing the number of passes over the media.

Set the lightness to lighter" to reduce the amount of ink used. Use HP media.

Migration (Black)

Description

In area fills, ink accumulates in the external part of the swath, where the black is more

saturated.

Causes

Ink not properly absorbed by the media, and surface forces, push the black ink to the borders

(due to the chemistry of the black ink). All the CAD media types except coated paper are

affected.
