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: Table 1-1.

Important system information and limitations

The following procedures take some time to accomplish: · Cleaning and preparing the ink tank can take between 40 and 60 minutes. You can save 20 minutes on the HP Indigo series 3000/4000/5000/7000 or UltraStream presses if you use a replacement BID, ink pump, and ink tank. · Ink formulation can take between 30 minutes (for one step) and 100 minutes (for three to four steps). Color 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. · Double hit: To achieve saturated solid colors, the HP IndiChrome ink mixing system software may suggest that you formulate the ink for double hitting. The double hit feature first prints the full image and then prints the 90% - 100% section of the grey scale. In this document, "double print" refers to "double hit". · Grey scale accuracy: To achieve grey scale accuracy that is similar to the process colors, it is recommended to perform an automatic machine LUT after the ink is installed. · Hot lamination: The printed colors may change during hot lamination, which may be required when preparing PVC cards. Mixing 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.

ENWW

Important system information and limitations 13

Resources: · 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 IMS and take advantage of its full range of features, experience and familiarity with the system is essential. The following phenomena are caused by using Rhodamine ink: · It causes the color of the squeegee (in HP Indigo series 1000/2000 and TurboStream-based presses) and the color of the developer (in HP Indigo series 3000/4000/5000/6000/7000/7200 and UltraStream 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.

ENWW

Preventing eye irritation

The HP IndiChrome ink mixing system uses inks and imaging oil that may irritate the skin and eyes. In extreme cases of exposure, these substances may cause blindness. As a precaution: Wear protective eye covering. This is of particular importance during the custom ink preparation. Install eye wash stations within 7.6 m (25 ft) of areas where the ink and imaging oil are handled, dispensed, or stored. Provide eye wash liquid at the eye wash stations (available from most safety supply companies) to comply with ANSI standard Z358.1-1990.

Electrical safety precautions

The shaker must be properly grounded at all times. Before operating the unit, ensure that it is grounded in conformance with applicable electrical code standards for your country/region. Do not operate the shaker if it is not properly grounded. If in doubt, check with a licensed electrician or with your local HP Indigo office. We recommend that you perform a weekly check of grounding cables.

Emergency power cutoff

Use one of the following methods to cut off power to the shaker in an emergency: Pull the electric plug out of the wall. Turn the timer to zero.

Flammable liquids and fumes

The HP IndiChrome ink mixing system uses flammable imaging oil. The following safety procedures should be used when working with this substance: Operate the unit in a well-ventilated room. Do not smoke or introduce external sources of ignition such as pilot lights, open flames, stoves, heaters, or halogen lights. Avoid creating sparks (static, electrical, or mechanical) or introducing any spark-producing equipment within 7.6 m (25 ft) of the system. Clean up spills immediately after they occur and dispose of soaked cleaning materials promptly in a covered waste bin.

ENWW

Preventing eye irritation 17

Handling and storing imaging oil and inks

To avoid fire or explosion, store imaging oil and inks in a fireproof cabinet or in a special combustible-liquids storage room. Only trained personnel should handle imaging oil and inks. See your local combustible material handling regulations. When handling imaging oil and inks, wear safety glasses with side shields, long-sleeved overalls, and protective gloves as indicated on the Material Safety Data Sheets. Do not drink or otherwise ingest imaging oil or inks.

ENWW

In the Automatic method, you use the HP IndiChrome Ink Mixing System to prepare a custom ink as follows: 1 Ink formulation: a b c d e f Determine (through measurement or PANTONE® color selection) the target color. Set the color match parameters (for example, substrate glossiness and type). Send the ink definition file to the HP Indigo press. Prepare and test a first can. If you are satisfied with the color, go to step 2 (Production). If you are not satisfied with the color, the HP IndiChrome Ink Mixing System will recommend improving the color in one of the following ways: - If the color in the ink tank can be improved by adding a slightly different custom ink, prepare and test a fix can. - If the color in the tank cannot be improved by a fix can, prepare and test a new first can. - Changing the optical density at the press. Repeat this step until you are satisfied with the color. 2 Production: a b c Prepare additional cans. Prepare the press for printing with the custom ink. Prepare the RIP (if necessary) to accept a print file with special colors.

In the Manual method, the HP IndiChrome Ink Mixing System does not determine the ink weights. Thus the only possibility for correcting a color is through a fix can where the ink weights used in the fix can is determined by the person preparing the color. Note Once you enter the Manual method, you cannot return to the Automatic or Ready Mix methods. In the Ready Mix method, the work in determining specific colors accurately has already been done. Prepare a first can to calibrate the press and prepare additional cans for production. Note If you are not satisfied with the results of a Ready Mix color, you can change (fix) the color using the Manual method.

Calibrating the spectrophotometer

Performing a full calibration

Before using the spectrophotometer for the first time, and once a month thereafter, perform a full calibration as follows: 1 2 From the Utilities menu, select Calibrate Spectrophotometer > Full Calibration. Follow the instructions in the series of message windows that appear, clicking OK after each message window.

Note

For the Black Calibration test, make sure that you measure the dark area until the four vibrating measurements end completely. This takes approximately 15 seconds. If the Black calibration successful and the White calibration successful messages appear on the screen, the full calibration was successful. If not, repeat this procedure one more time before calling the customer engineer.

Performing the daily calibration

Calibrate the spectrophotometer once a day. 1 2 Note From the Utilities menu, select Calibrate Spectrophotometer > Frequent Calibration. Follow the instructions in the window that appears.

For the White Calibration test, make sure that you measure the white reference area until the single vibrating measurement ends completely. This takes approximately two seconds. If the Calibration successful message appears on the screen, the daily calibration was successful. If not, repeat this procedure one more time before calling the customer engineer.

Adjusting the dispensing unit for the press

The HP Indigo series 3000/4000/5000/7000 and UltraStream presses use ink cans that are taller than those used by the HP Indigo series 1000/2000 and TurboStream-based presses. Consequently, the dispensing unit must be adjusted to the height of the ink cans used by the press for which you are preparing custom ink. Note For the HP Indigo series 6000/7200 presses, there is no need to adjust the dispensing unit. The dispensing unit can accommodate two nozzles: a short one for the HP Indigo series 3000/4000/5000 and UltraStream presses and a long one for the HP Indigo series 1000/2000 and TurboStream-based presses. The nozzle is screwed onto the top can holder. Figure 4-3. Adjusting the dispensing unit Can holder (top) Nozzle Short nozzle Nozzle storage hole Ring holder Weighing pan

Adjusting the dispensing unit for the press 31

Measuring a color

The spectrophotometer samples color data from any clean, dry surface that is reasonably flat and smooth. The target eye should be able to rest flat and steady on the sample area. Because the opening is just 6 mm (0.24 inch) in diameter, it can rest sufficiently flat on many curved surfaces. As a general rule, surfaces with bulky, rough, or loose-weave textures do not provide good results. Figure 4-4. Spectrophotometer Head

Shoe

White reference area Target eye Calibration reference base

To measure a color: 1 2 3 4 Clear the sample surface of any dirt, dust, or moisture. Place the spectrophotometer shoe directly on the surface, aligning the target eye opening over a continuous patch of the desired color. Press the spectrophotometer head down onto the shoe, and hold it closed. Hold the head down until the spectrophotometer stops vibrating. Make sure that you hold the spectrophotometer still for the entire measurement. Any movement affects the reading accuracy. Raise the spectrophotometer off the sample area, and carefully return it to its base.

2

Place at least one can of each basic ink into the shaker. There should be no more than four cans in the shaker.

Note Note

The only cans that need shaking are those that have not been shaken in the past 24 hours. If a basic ink can has been used previously, some imaging oil may spill out of the can during shaking. To prevent this, wipe the bottom of the can with a tissue and cover the hole at the bottom of the can with adhesive tape. 3 Operate the shaker to ensure that each basic ink is of uniform concentration. See "Shaking small ink cans" on page 47 for a detailed description of how to operate the shaker.

ENWW

Transferring the ink definition file to the press 43

Dispensing the ingredients

For a first can, new first can, and additional cans, use the weights shown in Best Mix (g). For a fix can, use the weights shown in +Fix (g). Figure 4-20. Best Mix (g) and +Fix (g) lists

1

Verify that the appropriate nozzle is installed in the dispensing unit and that the spacer ring is used if necessary. See "Adjusting the dispensing unit for the press" on page 31 for details. Before dispensing any ink, place an empty receiving can or fix bottle on the weighing pan of the electronic scale in the dispensing unit. Verify that the diaphragm is at the bottom (closed) end of the new empty receiving can by gently pushing down on it with the rounded end of a spatula.

2 3

Note

A fix bottle is sometimes used instead of an empty receiving can when preparing a fix can. For HP Indigo series 6000/7200 presses, if the amount of fix is less than 250 grams, then it is recommended that you use a fix bottle instead of an empty receiving can. 4 5 6 Open the transparent safety door of the dispensing unit, and insert the first or next ingredient can listed in the Ingredients list. Close the safety door. Press the red Tare button on the scale's base to set the scale to zero. Do this each time before dispensing ink from the different ingredient cans. Dispense the quantity of ink specified in the weight fields (Best Mix (g) or +Fix (g)) for the ingredient can that you inserted in the dispensing unit. Figure 4-21.

Note

The dispensing of transparent ink should be accurate to 3 g. All other inks should be accurate to 0.4 g. If the amount added was more than required, you may remove the excess ink from the receiving can or fix bottle with the spatula or a clean stick. If the amount of ink to dispense is very small (2 g or less), the following alternate dispensing method may be used: a b Dispense some ink into an empty ink can cover. Using a clean spatula, take small amounts of ink from the can cover and put them into the receiving can until the required amount of ink is reached.

Note

Beware of sudden ink spills. 7 (Optional) Select the check box that corresponds to the ingredient that you have finished adding to the receiving can. Figure 4-22. Ingredients list

Setting the mix precision

Mix precision is a parameter that refers to the color difference (E*94) between the color of the printed sample (actual mix) and the target color and to the difference between E*94 of the actual mix and the best mix. The main impact of the mix precision is on the type of messages you receive from the software. If the E*94 of the actual mix, or if the difference between E*94 of the actual mix and the best mix, is less than the mix precision, you receive messages such as: The Actual Mix is only xx units away from the target color. An accurate formulation has been achieved. With these messages, the software is merely suggesting that you complete the ink formulation stage; they are not imperative instructions. You may decide to continue trying to achieve a better match to the target color. In addition, mix precision determines the degree of metamerism that brings up the Metamerism window. The default value of the mix precision is 1. You can set the mix precision value to the maximum accepted E*94 value. Note See "E*94" on page 94 for an in-depth explanation of E*94. To set the mix precision: 1 From the Options menu, select Advanced. The Advanced Options window appears. Figure A-1. Advanced Options window

2 3

Type a value in the Precision of mix (E*94 units) field. Click OK.

ENWW

92 Appendix A Special options, basic concepts, and spare parts (all presses)

Note

The value for the E*94 can have values between 0.2 and 5, but setting a value less than 1 could take you longer to reach the required color. 4 From the File menu, select Save to update the ink mix file.

Window menu item usage

You can use the IMS Window menu item to view several mix files at one time (see "System file types" on page 95 for a description of mix files.) This enables you to compare the ink formulation and E*94 values for two or more different colors.

How to use the IMS Graphic window

The graphic display is an a*-b* plot (see "Color space" on page 94). The target color is represented by a plus. The outlined plus represents the desired target. The solid plus represents the best mix, which is the best achievable approximation to the desired target. Often, the outlined and solid pluses lie one on top of the other, implying that the target can be achieved precisely. The actual mixes are represented by circles. An outlined circle represents the actual mix that is currently in the ink tank. A solid circle represents a previous actual mix. To view the formulation of the best mix or of an actual mix, right-click on the plus or circle on the a*-b* plot. To zoom in on a region, click and drag the mouse on that region. To restore the default scale, right-click on the graphic display and select Restore Default Scale.

Decreasing ink thickness

If the print quality of the sample print (compared to the target color) is poor, the thickness of the ink layer may be too large. You can decrease the ink layer thickness as follows: 1 2 Select Edit > Ink Layer Thickness or . The Ink Layer Thickness window appears.

Select Decrease thickness, and click OK.

Using an old mix file for a new ink

When you open the IMS software, a new mix file appears. If one of the previously saved mix files includes colors that are similar to the color you want to prepare, import that mix file. From the File menu, select Import. IMS uses any relevant mixes from the old file to add accuracy to the initial formulation of the new ink. See "System file types" on page 95 for a description of mix files.

Special options 93

Basic concepts

Color space

Every color can be represented by the CIELab coordinates: L*, a*, and b*. The lightness, L*, indicates whether a color is light, such as Yellow, or dark, such as Dark Blue. An L* value close to 100 indicates a very light color, whereas a value close to zero indicates a very dark color. The coordinate a* indicates the green or red content of a color. A negative value of a* indicates a green color, whereas a positive value indicates a red color. Most colors used in printing have values of a* between -80 and 80. The coordinate b* indicates the blue or yellow content of a color. A negative value of b* indicates a blue color, whereas a positive value indicates a yellow color. Most colors used in printing have values of b* between -80 and 120. The three coordinates L*, a*, and b* form a color space, which is a three-dimensional space where every color is represented by a point in the space. The chroma C* is a measure of the brightness of a color. Colors with large C* values are referred to as bright (saturated) colors, whereas colors with small C* values are referred to as dull colors. C* is defined as: C

=

( a ) + ( b )

E*94

As a default, the HP IndiChrome ink mixing system uses E*94 to quantify differences between colors. If the value of E*94 is small, the two colors being compared are similar. If the value of E*94 is large, the two colors being compared are not similar. The CIE 1994 Color Difference Model defines E*94 as a replacement of the more familiar CIELab E*. The E*94 color difference improves upon the CIELab E* for color matching of saturated colors. Furthermore, E*94 is more uniform than E* in the sense that the perception of the difference between two colors is a direct function of E*94 and not dependant upon L*a*b*. In the IMS software, E*94 and E* see the color difference between the actual mix or best mix and the target color. The E*94 color difference is defined by:

C * H * + E L + 1 + 0.045C * 1 + 0.015C * target target

* 94 *2

2

2

The E* color difference is defined by:

E * L*2 + a*2 + b*2

where:

L* L* - L* target

* C * C * - Ctarget

* a * a * - atarget

* b * b* - btarget

H * a *2 + b*2 - C *2

94 Appendix A Special options, basic concepts, and spare parts (all presses)

ENWW

L*, a*, and b* are the color coordinates of either best mix or actual mix. E*94 places greater weight on variations in lightness and hue and less weight on variations in saturation. For unsaturated colors, such as neutral greys, E*94 is roughly equivalent to E*. The use of E*94 affects ink mixing results for saturated, out-of-gamut colors. These colors are so bright that a precise match is not possible. For these colors, it is impossible to simultaneously match the lightness, hue, and saturation. Since the lightness and hue are visually more important than the saturation, these two quantities should be matched as closely as possible. The use of E*94 ensures that the color you mix has roughly the same lightness and hue as the target color at the expense of the saturation. E*94 is more uniform than E*. For example, for E*, a color difference of three units between the target and the mixed color may be satisfactory for saturated colors, but unsatisfactory for neutral colors, for which one unit may be the maximum acceptable difference. This problem of uniformity is corrected by E*94. A single criterion for E*94 may be used for the entire color space. For example, a color difference of one unit may be the maximum acceptable difference for the matching of both saturated and neutral colors.

Color gamut

The gamut of a printing device is the subspace of the color space that contains all the colors that may be printed by the device. When a target color is found in the gamut of the ink mixing system, the predicted E*94 of the best mix versus the target color is zero. When the target color is outside the gamut, IMS computes the best mix with the smallest possible E*94. In this case, the color of the best mix is inside the envelope of the ink mixing system gamut. The E*94 value of the predicted best mix is therefore a measure of the color distance of the target color from the gamut of the ink mixing system.

System file types

The IMS software creates and uses the following types of files: *.mix This file contains the IMS screen information (environment). All of the information seen on the IMS window is contained in the mix file. You should save a mix file for each ink that you mix. *.gls *.mtt *.pvc These files contain the spectrums of given substrates. They are the library of substrates that you add and use. These files are used and/or created when choosing the substrate type. Ink definition files (see "Transferring the ink definition file to the press" on page 43): · The ink definition file is saved on a network disk drive with the .osm extension.
