Baud building; new digital phone lines pump of the transmission speed of your color files

Article Abstract:

Emerging digital telephone lines offer a variety of benefits to desktop publishers who need to send large color graphics files to remote printers or service bureaus. Analog phone lines are not suited for such communications because they require modems at both ends for conversion of digital data to analog signals for transfer at rates no higher than 14.4K-bps uncompressed. Digital communications, on the other hand, enable high-speed file transfers at rates as high as 1.54M-bps, which also facilitates simultaneous viewing of files at remote locations with no time lag, easy remote printing and proofing, online access to image archives and delivery of multimedia documents to consumers. The three types of available digital phone services are Integrated Services Digital Network, Switched 56 and T1, providing, respectively, maximum data transfer speeds of 116K-bps, 56K-bps and 1.54M-bps. Most of the US does not yet use digital phone services because of a lack of access, high cost of the hardware, lack of hardware standards and the fact that phone companies often do not understand the user's applications.

Reach out and see someone: the video phone is coming to a Macintosh near you

Article Abstract:

ShareVision Technology Inc's $3,000 Desktop Visual Communications (DVC) system for the Macintosh transmits full-motion video images and audio, has an address book, an auto dialer, an answering machine that will store audio and video and is even a fax modem. The system will transmit audio, video and data files simultaneously. Users can collaborate on projects by using the system's white-board application or by working on the same file simultaneously. Telemeetings and video mail are also potentially popular uses. The DVC operates at seven to 10 frames-per-second but needs to operate at the usual QuickTime rate of 15 frames-per-second to be marketable. Since there is no video telephone standard yet, the DVC uses its own compression standard. The DVC is considerably cheaper than other video telephone systems, but it is still out of the reach of most consumers. ShareVision's ability to overcome these obstacles will determine when the system will be brought to market.

More ways to get rid of unsightly film

Article Abstract:

Color laser copiers, thermal dye sublimation printers and color inkjet printers can be are cost-effective tools for quickly producing intermediate or final digital color proofs. Direct digital color proofing systems may cost $250,000 or more, and service bureaus may charge as much as $100 per proof page. Some service bureaus are using $35,000-to-$85,000 color laser copiers like the Canon CLC-500 and Kodak ColorEdge 1550 combined with a ColorAge ColorQ or EFI Fiery interpreter to produce intermediate proofs for $20 or less per letter-size page. Service bureaus are also using $7,000-to-$20,000 thermal dye sublimation printers such as PostScript-based RasterOps, SuperMac Technology and 3M units to produce prints that are richer and more consistent than laser prints for upwards of $40 per print. Taunton Press employs a high-end Iris 3024 color inkjet printer to produce final proofs for the firm's four-color specialty magazines.
