Development of Smart Assist Printing
Enhances Efficiency for Continuous Printing of Short-run WorkTo meet market demand for greater automation, easier operation and higher productivity
particularly for short-run jobs, RYOBI MHI Graphic Technology Ltd. (Katsushi Hirokawa,President) has developed Smart Assist Printing to enable automatic continuous printing ofmultiple jobs with a single touch operation.
Smart Assist Printing can automatically perform nonstop printing of multiple job by single
touch operation from ink preset, blanket cleaning, and plate changing to test print, registeradjustment, density adjustment and production printing. After completing the ink preset,
blanket cleaning and plate changing, sheets are automatically fed and test printing begins.
During test printing a CCD camera installed on the press captures images of the printed sheets
and the PQS-D printing quality control system performs inline inspection of printing quality.
Register alignment and density adjustment are also performed without having to sample theprinted sheets, and production printing begins once the register alignment and density arewithin the standard ranges. During production printing the PQS-D continuously performsprinting quality inspection, density adjustment and monitoring register alignment. Whenproduction printing of the first job is completed, printing of the next job begins in acontinuous printing cycle. The press automatically performs make-ready tasks that normallyrequire sampling of the printed sheets, shortening make-ready time by approximately 4
minutes*1 per job. Besides markedly increasing production efficiency for continuous printingof short-run work, less operator skill and experience are required. (For work requiring
customer verification of printing quality, a semi-assist mode allows the operator to determine
whether or not to advance to production printing.)
In conjunction with the development of Smart Assist Printing, the printing quality control
system’s Press Information Edge function automatically sorts jobs in the optimum orderaccording to the paper, ink, due date, and other conditions based on data sent from theprinting company’s main system. The density control system developed for the RMGT 10series is also available for the RMGT 9, 7 and 6 series, improving density adjustment toreduce paper waste and quickly achieve stable ink density. Paper waste until stable density isachieved greatly reduces by up to 40%*1 compared to previous RMGT 9, 7 and 6 seriesmodels.
Smart Assist Printing is available as an option on the 1020/1060 mm format RMGT 10 series,
the A1-size/A1-plus size RMGT 9 series, the B2-size RMGT 7 series*2, and the A2-size
RMGT 6 series. In addition to providing powerful support for operators by automating press
operation, it also meets the need for greater production efficiency for diversified, short-runjob.
