FLEXO Magazine : October 2011
When a camera produces too small of an image for its intended output size, has too little resolution, or the file has been saved in a lossy image format such as jpeg, it will result in a lack of detail. Pho- tos taken with point-and-shoot cameras are not good enough for flexographic printing, despite some common opinion. Poorly captured photos often re- quire costly corrections. These exces- sive image manipulations can cause isolated spikes that are separated by empty spaces in the histogram. This is called‘quantization of an image,’ and it indicates a lower image quality with a loss of subtle tonal variation. After cor- recting these poorly shot photos, color specialists will have to make additional corrections for dot gain, “substrate darkness,”and image mode conversion. This extra image manipulation worsens quantization, is counterproductive to im- proving the shot and will never compare to a photograph taken specifically for flexographic printing.

Small footprint. Minimal operating envelope. The 15-S is ideal for modern plants where space is at a premium and efficiency is a primary concern. It's unique face-to-face design enables both the unwind & rewind to be accessed and monitored from one central position. The highly efficient web path also minimizes the height requirement. Exceptional performance and features for a remarkable price. Every aspect of the 15-Series is state-of-the-art, except the price. From operator and maintenance accessibility, to speed and wide range of substrates, to premium F&K performance and quality — all at a highly competitive price. Today’s business environment requires solid reasons to move ahead. Examine the advances incorporated into today's Fischer & Krecke 15-Series flexo press and you'll have all the justifi- cation you’ll ever need. The Fischer & Krecke 15-Series Flexo Press Off-press set-up for minimal waste. Our revolutionary smartGPSTM, Graphic Positioning System, establishes registration and press settings before each flexo sleeve is mounted on the press. This eliminates the ‘trial and error’ fine-tuning of each color thereby eliminating over 90% of all of the materials wasted during typical job changes. Fastest changeovers in the industry. In addition to material waste, smartGPS also eliminates wasted time. When the sleeves are already set, press time is used to run jobs, not lengthy set-ups. Nobody else can do this because nobody else has anything like smartGPS. Bobst-F&K-15-S Ad_Layout 1 2/16/11 4:24 PM Page 1 64 FLEXo october 2011 www.flexography.org
