Scitex Continuous Tone or Scitex CT is an image file format. It is designed specifically for use on Scitex graphics processing equipment. Its use is supported by numerous graphics suites and desktop publishing packages, such as Adobe Photoshop, Adobe InDesign, and QuarkXPress. Wikipedia.

Warburger Klischeeanstalt (WKA), Warburg, Waldeckerland, Germany is one of the leading European companies that offers a wide range of packaging supply chain services. These packaging supply chain services play a key role in improving quality of flexo sleeves with new and high-resolution technology. The company has acquired expertise in laser-supported manufacturing of digital flexo-printing plates and has the potential to manufacture 45,000 round plates per year for flexo printing. It is also making efforts to develop and implement innovative new processes and technologies that will allow printers to derive more advantages from in-the-round flexo plates. The company's efforts involve continually researching the sleeve materials, printing screen technologies, and imaging resolutions that can help in improving the quality of in-the-round plates for flexo in prepress and laser manufacturing.

Dot gain is a classic problem in digital printing that causes printed halftones and text to appear darker than desired. For printing of text, we propose a method to preprocess the image sent to the printer in order to compensate for dot gain. It is based on an accurate model that predicts the printed absorptance for given local neighborhood in the digital image, a cost function to penalize lack of fidelity to the desired target text image, and the use of direct binary search (DBS) to minimize the cost. © 2014 IEEE.

Multilevel halftoning algorithms are becoming increasingly important as the capabilities of image output devices improve. The traditional approach to multilevel halftoning is hampered by the appearance of contouring in the vicinity of native tones of the output device. To overcome this limitation, we propose a novel framework based on maintaining a consistent periodic, clustered-dot halftone texture across the tone scale. We develop metrics for granularity and structure dissimilarity, and show how these can be used to guide the manner in which the halftone texture evolves from native tone to native tone, across the tone scale. Experimental results confirm the benefits of our new approach. © 2012 IEEE. Source

With digital printing systems, the achievable screen angles and frequencies are limited by the finite addressability of the marking engine. In order for such screens to generate dot clusters in which each cluster is identical, the elements of the periodicity matrix must be integer-valued, when expressed in units of printer-addressable pixels. To achieve a better approximation to the screen sets used for commercial offset printing, irregular screens can be used. With an irregular screen, the elements of the periodicity matrix are rational numbers. In this paper, we describe a procedure for design of high-quality irregular screens. We start with the design of the midtone halftone pattern. We then propose an algorithm to determine how to add dots from midtone to shadow and how to remove dots from mid-tone to highlight. We present experimental results illustrating the quality of the halftones resulting from our design procedure by comparing images halftoned with irregular screens using our approach and a template-based approach. © 2014 SPIE-IS&T.

HP has a very structured development process and it starts with plotting the broad-based, high-level understanding and needs of the market. Customer involvement is based on on-going visits, covering market sectors and geographic regions as well as companies of various sizes. While the HP Scitex FB7600 Industrial Press successfully accelerated the migration from screen to digital, a solution was needed to offer the benefits of digital production to flexo and offset converters. Among the goals for the new press were enhanced color and tone variations, smoother transitions from light to dark and improved image quality for fine detail and small type sizes. About mid-way in the process, following the continuing individual meetings, customers are brought together. These are managers and owners from all over the world. This is either in a virtual room, or real one, and customers are given tasks and situations to make them prioritize their requirements. Source
