Metainformation coding in inkjet printing process

The invention relates to a method for printing quality analysis in an inkjet printer (4) by means of a computer (3, 6), wherein printing is performed during the printing process, measurement is performed by means of an image detection system (2), a test pattern style (11) is analyzed by the computer (3, 6), and the analysis result is used for controlling the inkjet printer (4). Printing and analysis of the test pattern style (11) need to be synchronized. The method is characterized in that a code (9, 13) is integrated into the test pattern style (11) by means of local gray value adjustment, the code (9, 13) is detected by the image detection system (2) and analyzed by the computer (3.6) accordingly for printing quality analysis. 本发明涉及一种用于借助计算机(3,6)进行喷墨印刷机(4)中的印刷品质分析的方法，其中，在印刷进程期间印刷、借助图像检测系统(2)测量并通过所述计算机(3,6)分析测试图案样式(11)并将所述分析的结果用于控制所述喷墨印刷机(4)，其中，所述测试图案样式(11)的印刷和分析需要同步的进程，所述方法的特征在于，借助局部灰度值调整向所述测试图案样式(11)中集成入编码(9,13)，所述编码(9,13)由所述图像检测系统(2)检测并由所述计算机(3.6)相应地分析以用于进行印刷品质分析。
