Hi,
Since I work with Linocolor Elite (6.0.9) I'm looking for more information
about generic CMYK profiles for euro offset (positive plates) on coated and
uncoated paper (from Linocolor as Adobe as well).
For the same printing process and paper I found great (100%) difference
between the given values for dot gain compensation.
From Linocolor support I'll get information about the 'Offset-Euro-postive
plates' profiles. All these profiles are for coated paper and the dot gain
compensation is 18% (their no profiles for uncoated paper included by
Linocolor Elite).
Adobe's support tells me that the dot gain compensation in the Euroscale
Coated 2 profile is 9% and in the Euroscale Uncoated 2 profile is 15% (the
same values as standard shown in the Custom CMYK dialog box from Photoshop).
In the book 'Real World Photoshop 6' from david Blatner and Bruce Fraser I
read that the dot gain for Euroscale Coated is about 19% an for Euroscale
Uncoated is about 25% (table 5.1) and that the guideline for positive plates
is 10-12% (table 5.2).
Can somebody explain me why there such a great difference between the given
values.
Best regards,
