Page 19: Print Cycle
Print cycle Once the job is in the print queue, the press can begin the print cycle. The following steps are used in printing a job with the press: starting up charging and discharging the PIP inking the PIP transfer to the blanket printing the image Starting up To initiate the print cycle, in the control panel, click Print.
Page 20: Inking The Pip
Laser beams (12) selectively discharging the Writing head PIP drum Figure 2-6. Discharging the PIP Inking the PIP Binary ink developer (BID) units apply ink on the PIP. Ink is applied only to the discharged areas of the PIP. Ink particles are attracted either to the BID developer drum or to the PIP. The PIP discharged areas, which are the image areas, attract the ink particles.
Page 21: Transferring To The Blanket
Transferring to the blanket The PIP comes in contact with the intermediate transfer member (ITM) drum, which is covered by the blanket. The positively charged blanket attracts the inked image. The image is transferred from the PIP to the blanket (this is the first transfer). There should be no residue on the PIP.

Page 57: Printing Jobs
Printing jobs Jobs begin the printing process in the Print Queue. Their position on the list depends on urgency, substrate type, substrate thickness, number of colors in the job, or other job properties. Arrange the jobs in the list to facilitate the workflow. For example, all jobs that use the same substrate type or all jobs that use the same fifth and sixth color should be grouped and printed consecutively.
Page 58 Evaluate the printed job. Check for image placement in relation to the leading edge and to the left side margin (normally the image should be centered on the narrow axis and 10 mm [0.39 inches] from the leading edge). If necessary, open the Job Properties window, click the Image Placement tab and make corrections.

Page 63: Job Look-Up Tables (Luts)
LUT editing enables you to control the dot gain for every dot size individually. HP Indigo supplies several tailored LUTs, ranging from linear to Chromalin, with Chromalin applying the biggest dot gain. You can also create your own LUT or set a customized LUT as the default.
Page 64: Screening
HDI set 2 – an average of 250 lpi You can print a separation several times to enhance density. HP Indigo supplies you with alternative color order to support transparency printing. Inks “double-hit” printing Some Ink Mixing System inks require double-hit printing in order to achieve the desired color saturation, and this feature performs double-hit printing without screening artifacts (patterns).
Page 65: Color Match
To obtain the double-hit feature, open the Job Properties window, and select the desired color. Click Edit, and select the Double Hit check box. Figure 6-16. Double Hit check box Color match Color matching is the tool to use when color intensity needs to be changed. Unlike changing a LUT where every dot size can be manipulated individually, color matching is a fast but rougher tool.

Page 71: Consumables Overview
The sections are arranged in order of their frequency of occurrence. Ink replenishment HP Indigo ElectroInk is a patented liquid ink composed of a suspension of imaging oil and solid pigment particles. The concentration of the ink (ink density) decreases as part of the pigment adheres to the printed substrate.
Page 72: Paper Transport Adjustment
Note The press can print for eight additional hours before you need to replenish the imaging oil supply. You should replenish imaging oil at the end of the day or before a long break so that the imaging oil temperature will not be affected by the newly added imaging oil. Paper transport adjustment Every job is printed on a particular type of paper (or any printable substrate).
Page 73: Impression Paper Maintenance
Impression paper maintenance The impression drum creates pressure on the substrate against the ITM drum to allow transfer, and to carry the sheet from the input tray to the exit tray. The sheet is held firmly by the grippers throughout the one to seven press revolutions of the printing process. The impression paper protects the drum from ink.
Page 74: Color Adjust
Color Adjust The purpose of the color adjust procedure is to adjust the press to guarantee color repeatability across the run and between runs. The procedure allows you to set the density of the 100 percent dot and the 50 percent dot without altering the color reproduction curve.

Page 101: Overview
Overview HP ElectroInk, the ink used on the press, is mixed on the press from three components: imaging oil, imaging agent, and ink concentrate. Ensure a constant supply of both the imaging oil and the ink concentrate. The press system automatically identifies shortages of either of the two components, and prompts you to take the correct course of action.
Page 102: Draining The Ink Tank
The ink constantly circulates between the ink tanks and the BID. To compensate for the ink adhering to the PIP, the press system supplies ink concentrate from the ink cans. The imaging oil tank supplies the imaging oil when triggered by the level sensors. The press supplies imaging agent to the ink tank when the conductivity value in the tank is low.
Page 103: Replacing Ink Cans And Rebuilding Ink
11 Dispose of ink in accordance with your local waste disposal requirements. Drained ink that is not contaminated can be stored in sealed containers for later use. 12 Release the Emergency Stop by turning the knob until it is released. WARNING! Ensure that all equipment, tools, and materials are removed from the unit and that all doors are closed before operating the press.
Page 104: Rebuilding The Ink In A Tank

Clean the ITM shoulder below the IR temperature sensor using a lint-free wipe soaked with imaging oil.
Page 129: First Pressure Adjustment
First pressure adjustment Overview When the PIP drum or ITM drum pressure is adjusted in the press, you achieve full transfer of both the highlights (small dots) and the solids (100 percent dots). Adjust the pressure between the PIP and ITM drums on the front and rear controls using the First Transfer Calibration.
Page 130 When the following conditions occur, use the First transfer Calibration: After you change the blanket. When the ink coverage is partial and blank patches in the shape of white clouds appear on either side of the printed image. When the highlight dots (small dots) do not transfer to the substrate. Use the following procedure to adjust the first transfer pressure: On the control panel, click the Adjustments menu and select First Transfer Calibration.
