DuPont Packaging Graphics “Advancing Flexography” www.cyrel.com/na Until now, if you wanted the superior print quality and high press speed of continuous-print flexo sleeves, you had to accept the long lead times associated with custom-made products manufactured in Europe. Faced with a fast turnaround project? Your options were limited. Not anymore. DuPont is opening its first North American manufacturing site for Cyrel® round sleeves. Finally, you will be able to enjoy the benefits of Cyrel® round sleeves—gravure-like image quality, near-perfect register, improved tonal range, excellent ink laydown, high press speed and more— all with improved lead times. Whether you’re interested in solvent-process continuous print blanks or our new Cyrel® FAST round system, your choice has never been clearer. And, the results have never been faster. At DuPont Packaging Graphics, we create print technologies—innovations that move the flexographic industry forward. DPG-Rev Round AD-FLEXO.indd 1 5/23/11 7:57 AM Optimum Density & Spot Colors spectral Data Collecting software saves Time, Cuts Costs SpotOn! Flexo is a new pressroom software tool that flexographic press operators can use to target opti- mum density for spot colors. It compares the spectral data of a color measured on a press pull (using a spectropho- tometer) to the spectral data of the customer-approved refer- ence color. A quick calculation gives the press operator the optimal density to obtain the closest (lowest Delta E) match to the reference color. Patrick Gerrity and Richard Black of All Printing Resources, a distributor for this operator-friendly software package, note that, “There are many time-saving and cost-cutting benefits associated with its use. A major benefit is the reduced press make-ready time trying to obtain the correct color match to a spot or custom/brand color.” Other benefits include: • Monitoring the spot colors versus the reference color throughout a run improves consistency • Readings allow the pressroom team to foresee potential issues, such as changes in ink viscosity or pH • Timely troubleshooting of doctor blade wear, anilox roll plugging and plate wear In the Beta testing and the initial installations, custom- ers say they have experienced significant savings in press make-ready times and color matching. In some instances, users report that they have found that they can reduce the ink density to achieve a superior color match. Other users com- pliment the SpotOn! Flexo software and point out that it can immediately identify ink-related color match issues during the make-ready stage, saving press operators from spending countless hours trying to make adjustments on press. FEEDBACK DRIVES CHANGE “ SpotOn! Flexo will reduce the amount of time required to achieve a color match on press,” promises APR. Press operators will have immediate feedback as to whether density changes are required on press to achieve an optimal color match after the first color measurement. They will also receive immediate feedback if the color match cannot be achieved and ink formulation changes are required. Black and Gerrity say, “Anyone who has spent more than 10 minutes on press trying to achieve a color match to a reference color will benefit from instant color feedback.” The software uses simple color-coded icons to indicate if the color match is within the preset color tolerances or if ink density changes should be made to improve the color match. Ad- ditionally, if the acceptable color match cannot be achieved by density adjustments, the software will display a Red circle indicating ink formulation changes are required. n TECHNOLOGY TO WATCH SpotOn!
