When automatic colorimetric measurement and adjustment technology seems to have become standard in the field of web offset printing, this technology is now increasingly used in sheetfed offset printing. This is not only to ensure that the entire batch of printed products adheres to the quality standards, but also to quickly adjust and reduce the overprinting paper for adjusting the ink color when frequently changing the moving parts, which is environmentally friendly and reduces the cost. Today, sheetfed offset automatic colorimetric measurement and adjustment systems have different levels of expansion and price differences. Recently, "German Printers" brought together the system solutions introduced in the market, and introduced the latest systems of Manroland, Heidelberg and KBA.
Manroland
Grapho Metronic received the colorimetric measurement and conditioning system in Munich, which was established in 1967 and has been integrated as a subsidiary in Manroland since 1992. Manroland has an Inline Color Pilot automatic ink supply control system for 3B format presses that measures and adjusts the ink without taking out the sheets and measures the ink density at full speed of the Manroland 700 press. The InlineColor Pilot inline automatic ink delivery control system records the chromaticity values ​​of the entire batch of prints, helping the printer to avoid unreasonable complaints from customers. The system is available in 3B format Manroland 700 Hiprint and Manroland 700Directdrive models. According to Manroland, the Inline Color Pilot automatic ink supply control system is installed on the Manroland 700Directdrive direct-print offset press with glazing and extended delivery to complete 2,750 job calculations per year. The investment can be repaid (the recommended cleaning interval is 80 days).
The off-line Color Pilot automatic ink supply control system is used in the Manroland 500 and all large format machines, and the full set of control strips on the 3B format sheet can be measured in less than 14 seconds. A density-compliant polarizing filter is used for density measurement, so in-line density measurements can be made, but the measured chromaticity values ​​are not polarized. In addition, the “OK-Balance†color control option for the Inline Color Pilot inline automatic ink delivery control system was developed in collaboration with the Brunel system to ensure the maximum possible ink stability of the entire batch. Because the solid adjustment of the Color Pilot system complements the color balance adjustment, which allows the human eye to fluctuate much more when observing the four-color image and the third hue than when viewing the field.

KBA offers different levels of expansion for ink measurement and adjustment systems. The Densitronic is a purely off-line density measurement and conditioning system for quality control of pure density measurements. The densitometer is mounted directly on the Ergotronic console of the Rapida sheetfed offset press. The Rapida 75 offset press takes 4 seconds and the Rapida 205 mainframe takes 8 seconds. The measurement and adjustment system is available for Rapida 75, 105, 106, 130-162 and 185-205 models.
The Densitronic Professional system features a densitometer and a spectrophotometer mounted on a combined measuring head of an air bearing, so the chromaticity value can be determined in addition to the ink density (density measurement) during the measurement. In particular, the measurement and control system is placed directly next to the console of the press, allowing multiple presses to be centrally controlled. Spectral measurements are as usual, eliminating the need for density measurements of polarizers. This system can be used on Rapida 105, 106, 130-142, 162a and 185-205 models.
When the Qualitronic line system is used to inspect sheets, a complete in-line colorimetric measurement and adjustment system is involved on the Qualitronic Color Control. According to KBA, when using Qualitronic ColorControl, the overprinted pages can be reduced by 30%, and the measured value balance between dry and wet can be preset. Different functions such as the ink database and the substrate database can store material and process specific adjustments, as well as color changes during drying. 90% of new customers are directly concerned with the Densitronic system, and 15% of customers focus on Qualitronic system solutions. The Qualitronic system is an independent invention of the company, and the Densitronic system is manufactured by Lithec. KBA has patents in this special field, such as DE102006009383A1 (inline unit adjustment method and equipment for inking units) and DE 102006009382A1 (method and apparatus for adjusting the amount of ink and fountain solution).

Heidelberg has 3 different color measurement and adjustment systems. Prinect Axis Control works with all Speedmaster SM 52 to XL 162 offset presses. Prinect Image Control is used to control the Speedmaster SM 52 to XL 105, SM 102 and CD 102 series. Prinect InpressControl is the most automated because it can be used in the final printing unit, but only for a few presses such as the Speedmaster XL 75, XL145 and XL 162. In the event of a wet measurement challenge, the manufacturer follows some instructions from the ISO/POS (International Standard for Offset Printing Process). In order to achieve the required standard, the dry/wet ink value is determined in accordance with the ink sequence; in order to achieve the dry value required by the standard, the corresponding wet value is stored in the measuring instrument. Axis Control uses spectrophotometric measurement, and by connecting with Printect PressCenter, it can print up to 8 units of ink color adjustment for the front and back, and can achieve high-speed measurement of 200 mm per second. Printed control strips can be positioned anywhere on the sheet. The system automatically finds and identifies the type of strip in a 40 mm channel, which saves manual adjustments.
Image Control is a central colorimetric measurement and adjustment system for controlling four presses. It can be attached to the measurement patch of the printed control strip to automatically adjust the image on the sheet as the tonal value fluctuates. This is useful for logos or color on the ground, as the logo or color field must be absolutely in line with the corporate identity. Image Control measures about 160,000 points in 25 seconds.
The Inpress Control system is especially suitable for print operators who frequently change jobs and short runs. The system works in line, not only automatically measures and adjusts the ink color, but also adjusts the overprinting rules, and continuously monitors the continuous printing to ensure the stability of the entire batch of ink. The disadvantage of the Inpress system is that it cannot control multiple presses. In addition, Heidelberg will introduce new products for color measurement and conditioning systems at Ipex 2010.
If people don't want to use a solution directly from the press manufacturer, how do you choose? The first thing to know is that it is almost impossible for an outside manufacturer to have an in-line colorimetric measurement and conditioning system because the system works in a printing unit. For many users, offline measurements and adjustments are sufficient.
There are several suppliers in this area, of which the famous ones are Techkon and Xrite. Techkon offers a flexible ink and density measurement system called Spectro-Drive, consisting of a gauge mounted on a rail and a Techkon Expresso window software. The software wirelessly receives measurements from the meter and processes the fast visual analysis on the monitor. The advantage of Spectro-Drive is that it can be used in any printing size. The software can process up to 16 inking units. If you want to transfer the data directly to the printing machine's ink color adjustment device (closed loop), you can output the measurement data to other parts via JDF. program.
The Spectro-Drive meter was quickly removed from the rails by pressing the handle, making it a convenient handheld meter.
X-Rite
X-Rite has the Intellitrax product line in the field of color measurement. The measurement process of the printed control strip takes only 15 seconds. The measurement system works with CIP4, which supports CIP4 preset data and JDF for quick adjustment. The system has multiple expansion stages, the primary system Intellitrax D automatically measures density in four-color mode, and the Intellitrax system, which is the "standard" for automatic color measurement, is designed for four-color and multi-color printing. In addition, the Intellitrax ICC is suitable for making ICC files for printing presses. [next]
Brunel Systems
For decades, Brunel Systems of Switzerland has been working on the development of color measurement for offset printing. Printing the bar and maintaining the precise balance of color and gray values ​​is Brunel's expertise. As early as 1967, the first printed bar was used in the printing house. Brunel's expertise focuses on software development for quality control and analysis, and the colorimeter itself is not a product of its offering.
Brunel Systems worked with Quad Tech to provide a solution for web offset presses, while focusing on manroland in sheetfed offset printing. The Flight Online instrument is Manroland's expanded Color Pilot automatic ink delivery control system solution, and the OK-Balance color control function has also been used for the new Inline Color Pilot inline automatic ink supply guidance system. OK-Balance, including PrintConsult, has sold 1400 units in the last 10 years and about 40 Flight0nlin instruments.
Regarding the dry/wet problem during measurement, Brunel Systems estimates that the polarizing filter helps to minimize the difference between dry/wet sheets. The problem is obvious if the wet sheet is adjusted according to the density in the field or the color measurement in the field. However, with the Flight instrument, most of the process variables resulting from the gray balance prioritization are included, thus reducing the effects of dry/wet problems.
DIGITAL INFORMATION in Switzerland offers a complete line of ink alignment systems for all important printer manufacturers. The company's experts rely on reverse engineering development software because almost no manufacturer makes it voluntarily open for the interface of press control.
According to the manufacturer, 2,000 offset presses worldwide are connected to DIGITAL INFORMATION' solutions. On the measuring instrument, X-Rite's Intellitrax and Techkon's Spectro-Drive are supported. As an entry solution, the supplier also developed an electric drive (DC2/4/8) for X-Rite's inexpensive Eyeone spectrophotometer, and the same drive as the Digi-Densi's pure density measuring head.
DIGITAL INFORMATION announced that it will continue to improve the ink color adjustment algorithm for Ipex 2010, connect with the inline measurement system and expand the ISO standard report.
