Print On Demand

A Print-on-Demand (POD) System was developed to expand the availability of printed extension and educational materials. The layouts are developed on a computer using text files and digital images. Images can be edited with graphics programs before insertion into the layouts. The completed materials are stored, in final format, on disk and are printed on an as-needed basis or distributed over computer networks. The system greatly reduces the production time to a finished product and gives great flexibility in revising publications. The basic POD system consists of a computer, a mass storage device, and a printer. Photo CDs and video capture are the most common sources of digital images. Photo CDs produce higher-quality images but require more time to get the digitized images due to commercial processing. For Photo CDs, the images are photographed with a 35-mm camera and sent for processing and digitizing. With live video capture, a video camera is connected directly to a computer and images are digitized in real time. Tape recorded images also can be used, but the image quality is less than live video. Video images are digitized at 72 pixels per inch (ppi), and Photo CD images are available at >3000 ppi. Video images are best digitized at twice their desired size and reduced to final size when increasing the resolution.

Print On Demand

A Print-On-Demand (POD) System was developed for the rapid production of educational and extension materials such as fact-sheets. Information is stored in a final format on the computer and the number of copies of a specific publication can be printed as needed. The system greatly reduces the time to having the finished product and allows any number of publications to be printed. The printing cost ranges from $.43 to $.80 per page with a 300dpi color thermal wax printer. Photo CDs and video capture images are the most common sources of color images used in the POD system. Photo CDs produce higher quality images but require time to process a film before images are used in the system. In live video capture, an image can be captured by a video camera, and sent to a computer for immediate production of a fact-sheet. Tape playback reduces the image quality compared to live video. Live video also gives the best feedback in determining whether the image shows the desired information. In general, the image is video captured at twice the needed size and reduced while increasing the resolution from 72 dpi to 130 dpi. This produces a better quality image. Other sources of pictures are flatbed scanners and slide scanners.

Scanned Images

Options for acquiring digital images are explored. Photo CDs, scanned images, and video capture are the most common sources of images. Photo CDs produce the highest-quality images, but require more time to get the digitized images due to commercial processing. For Photo CDs, the images are photographed with a 35-mm camera and sent for processing and digitizing. Slide and flat bed scanning is time consuming when working with bulk quantities of images. With live video capture, a video camera is directly connected to a computer and images are digitized in real time. Tape-recorded images can be also be used, but the image quality is less than live video. VWeb server allows rapid dissemination of the materials. This procedure greatly reduces the production time to a finished product, gives flexibility in revising publications and allows a greater variety of materials to be produced.

Digital images are becoming an essential part of computer “slide” presentations, identification of plants and problems from a distant location, and adding visual elements to Web pages. The use of digital video images allows capturing of single frames for individual or sequence photographs as well as “mass” storage of digital images. There are also some uses of short “video clips” to be included in slide or Web presentations. A discussion of digital image quality and demonstration of equipment used will be included in the presentation.

Print On Demand

Print-on-demand (POD) publications are being produced from computer to printer to increase the diversity of printed extension and educational materials. The layouts are stored in libraries on the computer and text files and digital images are added to the layouts. Images can be edited before insertion into the layouts to enhance the image. The completed materials are stored in portable document format (PDF) on disk and are printed as needed or distributed over computer networks. Printing materials as needed greatly increases the diversity of materials and gives greater flexibility in revising publications than bulk printing.

The use of video images in biomechanical analyses has become more realistic since the introduction of the shuttered video camera. Although recording rates are still limited to 60 Hz, exposure times can be reduced to prevent blurring in most situations. This paper presents a system for manually digitizing video images, a system that utilizes a video overlay board to place a set of cross hairs directly on a previously recorded or live video image. A cursor is used to move the cross hairs over required points. A BASIC program was written for a IBM PC-AT computer to accomplish this task. Video images of a known set of points were digitized, and calculated distances between points were compared to real distances. The mean of the observed errors was 0.79%. It was concluded that this digitizing system, within the limitations of video resolution, yielded digitizing errors similar in magnitude to those observed in cinematographic analyses.

Print on Demand Ausgabe (Lieferzeit ca. 3-4 Tage) Dieses Buch gibt einen vollständigen und aktuellen Überblick über "Public Relations" in Theorie und Praxis. Nach einer Klärung des Begriffs erläutert es die Beziehung von PR zu anderen Konzepten wie Propaganda oder Marketing und diskutiert das Verhältnis von Kommunikationswissenschaft und PR. Dabei werden Probleme wie Theoriebildung, von Theorie und Empirie sowie der Verwertbarkeit wissenschaftlicher Befunde und Ethik behandelt. Die Entwicklung der deutschen PR-Theorie schließt sich an. Einen weiteren Schwerpunkt bilden die PR-Theorien, die auf die Managementfunktion von PR verweisen. Die aktuelle Diskussion um PR als symmetrischer Dialog wird ebenso behandelt wie neue systemtheoretische Ansätze.
