Keif Face it, margins are tight and are likely to remain that way. We all know that you can improve revenues in two ways: raise prices and/or reduce costs. Raising prices is possible when you have a unique value proposition that cannot easily be replicated. Customers are willing to pay more for that value. For the rest of us, reducing costs is a key to improving revenues. So, how do you reduce setup time? What is the process of shortening a makeready? There are various strategies ranging from lowering the quality standards (a bad idea) to purchasing expensive and sophisticated new equipment. New presses nearly always have faster startups. However, my preferred method for reducing makeready time, is a proven strategy that does not involve lowering standards or investing heavily in equipment. Developed in the automotive industry, SMED (Single Minute Exchange of Dies) outlines a structured process for analyz- ing and reducing makeready times for any operation that involves discrete setups. While it was developed in the context of setting up stamping dies in the automotive industry, its application is far reaching. This includes printing presses, converting lines, and platemaking. Makeready time is undesirable. Customers do not value it. Generally considered part of the print process and factored into cost estimates, the fact remains that makeready times can be reduced, and the printer can either increase profit or lower pricing. The SMED process was initially outlined in the 1985 book: A Revolution in Manufacturing: The SMED System by Shigeo Shingo, an industrial engineer who developed the meth- odology for Toyota. The process was further refined for the LOWERING COSTS WITH SMED • SMED (Single Minute Exchange of Dies) outlines a structured process for analyzing and reducing makeready times for any operation that involves discrete setups • In recent years, companies have really begun to put energy into pre-makeready functions, including staging substrates, inks, dies, foils, etc. • Analyze every internal and external process to determine any hang-ups or possible areas of improvement • SMED, originally developed in the automotive industry, is applicable across many fields, including: printing presses, converting lines, and platemaking • While there are few huge gains, five minutes shaved here and five minutes shaved there add up to significant reductions 20 FLEXO octoBer 2012 www.flexography.org Fall Conference Preview
