User guide introduction
It is often desirable to print with spot color inks in addition to the Cyan, Magenta, Yellow,
and Black (CMYK) process colors. The HP Indigo presses enable you to use such special
inks. The HP IndiChrome ink mixing system (IMS) gives you the capability of preparing
the special ink you require by mixing inks from a set of basic inks. Because the inks are
specially tailored to customer requirements, the inks are referred to as custom inks.
This user guide is suitable for the following HP Indigo presses and Indigo presses:
User guide structure
This user guide is divided into the following chapters and appendices:
z1. Introduction. Briefly describes the purpose of the HP IndiChrome ink mixing
system, explains the conventions used in this guide, lists the system requirements
and hardware configuration, lists the consumables that you can order from HP Indigo,
and gives relevant operating information.
z2. Safety and environment considerations. Describes the safety precautions you
should take when operating the system.
z3. Getting started. Shows you how to determine the workflow for ink mixing and how
to start and quit the HP IndiChrome ink mixing system software.
z4. General procedures. Describes the procedures that are performed during the
various ink preparation steps: how to calibrate the electronic scale and
spectrophotometer, measure sample colors, adjust the air pressure of the dispensing
unit, prepare basic inks, dispense ingredients, and seal and shake cans.
z5. Additional IMS procedures. Describes additional procedures and capabilities of
the HP IndiChrome ink mixing system software: including using Ready Mix colors,
continuing work on a previously defined mix color, manual color mixing, importing .mix
files, adjusting the view of the 2D color space and viewing the 3D color space.
zAppendix A. Special options, basic concepts, and spare parts (all presses).

Important system information and limitations
zThe following procedures take some time to accomplish:
• Cleaning and preparing the ink tank may take between 40 and 60 minutes. You can
save 20 minutes on the Series 3000/4000/5000 or UltraStream-based press if you
use a replacement BID, ink pump, and ink tank.
• Ink formulation may take between 30 minutes (for one step) and 100 minutes (for
three to four steps).
zColor accuracy:
• Gamut: In some cases, the target color may be outside the gamut of the
HP IndiChrome ink mixing system. This situation is characterized by having the
predicted best mix color differ from the target by a ∆E*94 of more than zero. In this
situation, the software guides you to achieve the mix that best resembles the target
color, regardless of what the predicted ∆E*94 is.
• Gloss: When the gloss of the target color sample is substantially different from the
printed color, it may be difficult to visually compare the two colors. For a glossier
target you can overcoat or laminate the printed sample with a glossy substance
before the comparison. You can even manually apply some imaging oil onto the
surface of the color to get the required temporary increase of the gloss or laminate
the sample with a transparent glossy scotch tape.
• Grey shades: In Sun computer-based presses with off-line densitometers, the LUT
of the custom color is the same as the LUT of Black. Therefore, the color shades
may not appear as linear as they should be.
• Double print: The HP IndiChrome ink mixing system software may suggest that
you formulate the ink for double printing. This occurs when the best mix color in
single print is not bright enough. If you print the separation of such ink twice, the
solid color effect is accurate but the color shades are not. Therefore, double print
should be used for printing solids only. If you double print shades, they are not
linear.
• Hot lamination: The printed colors may change during hot lamination, which may
be required when preparing PVC cards.
zMixing procedure:
• Ineffective mix: Some of the fix corrections may not improve the color. This reflects
the statistical nature of the corrective algorithm. In such cases, you may still expect
improvement of the color in successive corrections.
• Inaccurate mix: The color of the actual mix usually differs from the target color
more than the software prediction shows. This is mainly because of minute
contamination in the ink tank, inaccurate dispensing of the basic inks into the mix
can, and specific characteristics of the substrate in the print run. This is especially
true with colors that are outside the gamut.
• Precision in color adjustment: During the ink formulation stage, you are instructed
to correct the color by printing again with a modified optical density (OD) value.
Because of the limited precision of the color adjustment procedure, this instruction
may be repeated until the OD, as read by the spectrophotometer, is as required.
• Resending the ink parameter file: Do not send the ink parameter file to the press
more than once. If for some reason this has been done, you should use a first can
for recalibrating the ink density sensor.

zResources:
• Initial ink amount: The amount of concentrated ink in the ink tank dispersion is
equivalent to almost one can. In order to print the job, you should prepare and
install at least one additional can. The weight of the ink in the can may be as small
as required for the print run. You must prepare at least one can of ink even if the
printing job consumes much less.
• Getting acquainted: To correctly operate the ink mixing system and take advantage
of its full range of features, experience and familiarity with the system is essential.
zThe following phenomena are caused by using Rhodamine ink:
• It causes the color of the squeegee (in Series 1000/2000, TurboStream-based, and
Sun computer-based presses) and the color of the developer (in Series
3000/4000/5000 and UltraStream-based presses) to change to yellow. However,
no deterioration of any other characteristics of the squeegee or developer is
expected.
• It causes an excess of particle residue to be found in the separator clean liquid and
on the blanket background.
Under normal circumstances, no degradation of print quality or machine reliability
is expected. When printing more than 1,000 pages with Rhodamine as one of the
separations or when printing with an ink mix containing a large percentage of
Rhodamine, slight contamination of other inks may occur. The expected color
shift will not be larger than ∆E*
94
= 1.5.
