Test Targets 7.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control

Test Targets is a culmination of teaching and learning that reflects quality and analytic aspects of printing systems and their optimization. The creation of the Test Targets publication is a total experience that reflects the innovation, problem solving, and teamwork of the diverse team of faculty, staff, students, and professionals responsible for its contents and production

SAP HANA Database: Data Management for Modern Business Applications

The SAP HANA database is positioned as the core of the SAP HANA Appliance to support complex business analytical processes in combination with transactionally consistent operational workloads. Within this paper, we outline the basic characteristics of the SAP HANA database, emphasizing the distinctive features that differentiate the SAP HANA database from other classical relational database management systems. On the technical side, the SAP HANA database consists of multiple data processing engines with a distributed query processing environment to provide the full spectrum of data processing -- from classical relational data supporting both row- and column-oriented physical representations in a hybrid engine, to graph and text processing for semi- and unstructured data management within the same system. From a more application-oriented perspective, we outline the specific support provided by the SAP HANA database of multiple domain-specific languages with a built-in set of natively implemented business functions. SQL -- as the lingua franca for relational database systems -- can no longer be considered to meet all requirements of modern applications, which demand the tight interaction with the data management layer. Therefore, the SAP HANA database permits the exchange of application semantics with the underlying data management platform that can be exploited to increase query expressiveness and to reduce the number of individual application-to-database round trips

Test Targets 10: A Collaborative effort exploring the use of scientific methods for color imaging and process control

Th ere are six papers that were written, peer reviewed, and published in Test Targets 10. Two papers focus on printing standardization and conformity assessment. Chung describes aims and tolerances specified in ISO 12647-2 and the use of color measurement and data analysis for conformity assessment. Urbain and Khoury describe data reception requirements in ISO 12647-2 and ISO 15930 and the use of a test pdf file to assess conformity of any pdf workflow. Test Targets 10 will likely be remembered as the publication that covers OBA (optical brightening agents). Two papers focus on OBA. Tian and Chung report the effect of paper containing OBA on printed colors and how such effect can be corrected using different mathematics. Sigg and Millward report the stability of OBA as a function of exposure to light over time. In addition, Gallery of Visual Interest shows side-by-side the visual effect of pictorial and synthetic color images printed on paper with and without OBA. Printing conformity is result-oriented and does not dictate the press calibration method used. The fifth paper, authored by Wang, compares the compatibility of two press calibration methods, TVI and G7, by means of gradation compensation and press run simulation. Printing conformity requires that correct inks and paper be used. Verifying that correct inks are used is outside the capability of a printer. Th e sixth paper, authored by Zhang, explores an alternative ink drawdown and ink verification method that could be implemented by printers. Test Forms is a regular feature of Test Targets. We are pleased to showcase pictorial color reference images, Roman 16 Reference Images, courtesy of Bundesverband Druck und Medien e.V. (bvdm), and many possible uses of these images for printing process control and for color management studies. For example, we can compare the appearance of an image printed from the supplied CMYK file with the image from a supplied RGB file that was converted to CMYK by a color management application

Test Targets 8.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control

Publishing is both a journey and a destination. In the case of Test Targets, the act of creating and editing content, paginating and managing digital assets, represents the journey. The hard copy is the result or destination that readers can see and touch. Like the space exploration program, everyone saw the spacecraft that landed on the moon. It was the rocket booster that made the journey from the earth to the moon possible. This article portrays the process of capturing ideas in the form of digital data. It also describes the process of managing digital assets that produces the Test Targets publication

Test Targets 6.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control

Test Targets is a collection of scholarly papers contributed by faculty, students, and alumni of Rochester Institute of Technology. We realize the importance of having faculty set examples as authors for students to follow. We have a three-course sequence over a time span of a year to prepare students to publish their first articles when completing Tone and Color Analysis, Printing Process Control, and Advanced Color Management. In this instance, Test Targets 6.0 is a part of the course content in the Advanced Color Management course

Test targets 5.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control

Test Targets is about scholarship that intimately involves faculty and students in the process of writing and publishing. It is a collection if research papers that require collaborative effort over a time span of three academic quarters. Initially, students learned metrology, color management system, and the use of test targets for device optimization and process control. As time goes by, students are encouraged to identify research topics, formulate methodologies, and carry out experiments and data analyses in order to have specific findings. - p.

Test Targets 2.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control

Test Targets 2.0 was a class project in Test Targets for Graphic Art Imaging in the winter quarter of 2001-2 academic year. The objectives were to put together a collection of custom test forms, developed by Professors Robert Chung and Franz Sigg, and to coach students to showcase possible use of these test forms along with associated Microsoft Excel templates for device calibration and process control when implemented in a color managed digital workflow. - p. iv

Test Targets 3.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control

Test Targets 3.0 focuses on the integration and analysis of a number of input devices, color image renderings with the use of a robust CTP system and a full-fledged web offset press … The first section is a collection of test forms … The second section is a compilation of color management practices by the class. – p. v

Test Targets 4.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control

Test Target 4.0 (TT4.0) is the result of student teamwork to publish a technical journal for a graduate-level course titled: Advance Color Management (Course no. 2081-735-03). Offered by the School of Print Media (SPM) at Rochester Institute of Technology (RIT), the course is a platform to experiment and to realize a new digital imaging paradigm and the dynamics of teamwork.... Team members learn scientific methodology in process control for repeatable color as well as apply ICC-based color management practices in digital workflows. They plan and conduct press run analyses reported in TT4.0, which is printed using facilities available at RIT. In producing this publication, the team learns to integrate design, content creation, digital media, and print production in a seamless workflow.... -p. 4
