Hybrid Advanced Sceduling of Label Packaging Printing Process Advancement for Letterpress Press Systems

Printing process improvement has recently transformed into an impacting bottleneck after digitalization throughout the printing press Despite the recent success of consistency and results of quality at the pre-press, press, and post-press machines, timely delivery and lead time consistency are the biggest obstacles for all printers in Thailand New hybrid scheduling algorithms are innovated from this paper in the needs of guaranteed lead time and cost efficiency Two of the six existing press systems consisting letterpress flatbed and letterpress intermediate rotary press systems are being studied, simulated, and experimented These roll to roll types of raw material printers found to have distinct maximum speed ranging from 10 to 60 meters per minute or 40 to 200 rounds per minute As observed results, it is shown that the advanced hybrid scheduling enhanced more than 30 percent of the flexibility to cope with rush orders and job shifts, and reduced no less than 20 percent of job delay frequency Besides these significant results, the new algorithm requires planner and the printer operator communicated with printing algorithms to perform with relatively fewer human errors These indicators are the introductory and promising results from the new hybrid scheduling algorithm To conclude, the hybrid multilevel scheduling is a comprising digital advancement in planning process for press manufacturers to implement and further expand its application fields
