Sheetfed Presses–Getting Connected
Another manufacturer looking to improve the connection between prepress and the pressroom is industry powerhouse Heidelberg USA. According to Cai von Rumohr, Speedmaster 52 product manager, that connection is being made with the new generation of CP2000 presses. CIP3 information can be sent with the help of the CPC32 prepress interface, which gives information on ink key profiles directly to the CP2000 presses, thus, makeready time can be reduced.
“The Windows NT-based CP2000 allows users to select modules and add on certain features that enhance the productivity of the press itself and the link to the press by exchanging information directly with production planning, estimating and scheduling systems or with CIP3 digital prepress data,” he says. “It’s an open, upgradable system that users can complement at any time.”
Quality control devices is another issue that’s being addressed, according to von Rumohr. New spectrophotometric quality devices, based on an independent color space like CIELAB, help to reduce makeready time and waste; shorten press checks; ensure color consistency over a long run; standardize the color produced on multiple presses and multiple shifts; and provide more standardized procedures to ensure document consistency and quality day in, day out.
Heidelberg has been marketing its CPC 21 spectrophotometer as an answer to that growing need for quality control, but has only recently added the CPC 24 ImageControl as the new high-end brother, which goes a step further by reading the entire sheet in seconds.
To address the need to link the press back to the entire prepress area, KBA North America, Sheetfed Press Div., has developed the CIPtronic Work Station.
“The objective still remains to cut every bit of time that the press is not producing sellable work between one job and the next, and to make the workflow as automated as possible—from prepress all the way to the pressroom,” states Robert McKinney, director of sales and marketing.
