Heidelberg Prinect Color Solutions Application Experiences and Tips

Ink standard

Offset printing standards will be more and more demanding - these requirements will change the way the printing shop operates. The reason behind this is clear - using the binding standard means that the entire department can predict the results and can compare the quality without having to consider the location or output device. The requirements of the printing customer are more irrelevant to the printing factory, regardless of the price offered, which is a decisive factor in confirming the order in the future. There are many factors that can affect the final color result from the digital press to the finished press sheet, including the new ink type or the dot gain generated by the printing plate changing the ink overprint performance. Sometimes users submit data and proofs to let printers deal with color specifications that are difficult to achieve on the press. Regardless of the way you look at it, the “printing effect of the press” is an expensive and inefficient process that often produces unsatisfactory results. If no matter what efforts are made, the results of the printing cannot be matched with the proofing, and the door of complaints will be greatly opened. Therefore, the reliability and stability of ink delivery are the most basic conditions for each printer.

Steady infusion of ink from the beginning

Prinect Color Solutions can faithfully reproduce color throughout the entire workflow. This solution provides a large number of products and solutions that enable true color, low-cost production. By ensuring that all components work together effectively and with precise control, the system is able to obtain the maximum possible faithful reproduction of colors, has the highest quality standards in the printing process, and has significant advantages in production. These advantages can only be achieved in Heidelberg, Heidelberg is the only manufacturer in the world that can provide color management from the prepress to the entire printing process.

Targeted color management

The proofs, plates, and prints should all have the same color effect. To achieve this, we need to look at the colors from the point of view of the press to see how the various components of the above process interact. This means that the “fingerprint” of the printing press is integrated into the prepress stage, so that any change in the printing conditions will be automatically reflected in the proofing process and the plate making process of the printing plate.

Therefore, by integrating presets, measurements, calibrations, and characterizations into a single loop, the desired inking results can be obtained.

Prinect Color Solutions in Practical Applications

Perhaps you want to know more specific examples of how this process operates? Use the Prinect Easy Access system to calibrate the integrity and printability of customer-supplied PDF files. Use the appropriate ICC profile to adjust for colors that cannot be matched by current printing ink printing. Then printed documents can be printed by Prinect Stars for inspection on the proofer. The final simulation of the print was performed with the signature file interfaced with the printer and the proofer. If there is no problem with the proofing, the data will be transmitted to the connected laser imagesetter by Prinect Star, and then the printing plate will be produced. The correct calibration feature is automatically selected.

At the same time, Indochina stars generate digital files with preset parameters, provide digital reference values, and check the printed sheets through Prinect image control software. Proofing proofs, plates, and pre-set data are sent to the pressroom at the same time. The Prinect Calibration Toolbox and Prinect Feature File Toolbox generate different output conditions and verification characteristic curves of the ICC profile. Measurements Measurements can be easily performed using Prinect Image Control Software or other colorimeters.

Color fidelity in printing

Next, the Prinect Prepress Interface calculates ink coverage values ​​for the ink used by the printer based on the prepress data, and transmits these data along with registration marks and other preset values ​​to the Prinect CP2000 Control Center. In this way, in the setting process, the ink delivery process is highly automated, greatly reducing the press preparation time. Select the correct ink preset value on the press depending on the ink and paper grade used. If you consider the situation of consumables, you can quickly achieve optimal infusion. At the same time, Prinect Image Control Software accepts pre-press reference values, resulting in digital signature samples. The measurement results in the production run are returned to the prepress by the Prinect Image Control Center so that adjustments can be made after the production conditions have been changed. Only by tightly linking the printing press to the prepress stage in this way can we respond quickly to changes in printing conditions.
