(under the Detailed Production Processes > Color profiling and refinement
chapter).
Magenta1 Separation
Magenta1
separation is used as part of the
Indichrome
process using CMYKOV. The extra separation
is intended for reduction of moiré for large areas of print that use Orange ink as part of the process
(Orange shares the same screen angle as Magenta which can cause moiré). Magenta1 is recommended
for quicker, more accurate color.
Magenta1 should only be removed as part of the Strategy for proper color process conversion
. Issues
will arise if Magenta1 Separation is disabled at either the Press or DFE Job Properties.
Naming conventions
It is important to have a
color strategy name
that can quickly and easily indicate the exact purpose in
creating that color strategy (i.e., what is it to be used for).
Here are some suggested naming conventions for profiles / strategies:
●
Ink Set_Substrate name_LUT_Linescreen_Creation_Date
(for example:
CMYKOV_BOPP_Linear_196_Apr082017
).
●
When printing on Clear or Metallic, white ink may need to be used
(for example:
CMYKOVW_MetPoly_Linear_196_Apr082017
).
–
A custom ink name for White may be needed
–
Extra Output Inks – white would be assigned
Other things to keep in mind when naming Color Strategies and/or jobs:
●
Only alpha numeric characters, underscores and dashes are allowed.
●
Characters not supported include: #@*(.,%]?/”)
HP Indigo Digital Presses color specifications
The color specifications listed in the tables below represent the nominal tolerance that we can indicate
as being achievable at the HP Indigo digital presses. However, if customers follow the operation-related
recommendations, they can obtain better results than indicated by the nominal color specifications.
