When performing ‘Nesting’, Neighboring area fill dependence

When performing ‘Nesting’
In some very extreme and specific cases, depending on how the plots are organized, you might see a
color difference within one area fill, while there is no color difference within the original job.
Here is an example of two plots nested:
To solve the issue so that you cannot see the color shift in the middle of the job 1, you can reorganize
the nesting (or do not do nesting).
Neighboring area fill dependence
Here is an example of job where a slight variation of color is visible:
Mainly when printing in Unidirectional, the light gray area on the left of the b
igger red rectangle is showing
a little more yellow. When the red rectangle is smaller, this effect is no longer visible. When printing in
bidirectional, the effect is also less visible.
When printing area fills on some substrates
The following issue can be seen when printing some specific area fills on some substrates which are
prone to a higher level of shrinkage (or when the dynamic color registration calibration is not optimized).
In this case, the relative positions of the dots of inks, between Yellow/magenta and Cyan/black can be
completely different towards the edge of the substrate compared to the middle of the substrate. When
