FLEXO Magazine : February 2012
role color management plays in ensuring the company ’s long-term, sustainable growth and market share. As brand owners raise the color bar, how do packaging printers respond? Is it possible to create a comprehensive color control process across one—let alone multiple—print sites overnight? Or is it more likely to succeed by controlling color quality incrementally. Here is one strategy for breaking down the color quality control process in four color-manage- able “stepping stones”. Color’s ImpaCt Where can a company start a color control process and how can it find the biggest paybacks? Typically the further downstream a color control issue develops, the more expen- sive it is to fix in terms of press downtime, wasted ink and paper and failed customer expectation. Consider this typical scenario: During a pressrun, mid- tones are unattainable (50 percent). The first option is to make multiple density adjustments, change inks, fountain solution, make blanket adjustments (over/underpacking), and slow the press speed. Even after one has burned through hun- dreds, maybe even thousands, of sheets with no solution in sight. Nothing seems to work. What is causing this problem? Excessive non-mechanical dot gain caused by printing plates that are not linear or that were not processed with the right correction curve. This requires the press to stop, application of corrections, processing new plates, mounting them on the press and start print production from the beginning. This translates to substantial costs in lost production time, wasted paper and ink and negatively impacts customer expectations on the promised delivery. How could this have been avoided upstream? By using a printing plate measurement device to determine if the plates were processed with the correct values Spectrodensitometers measure the color being printed and compare it against customer-approved color specifications and tolerances.
