Do the following: 1) Turn off the power switch. 2) Unplug the folding stations and/or deliveries from first station. 3) Plug a blind/dummy plug into first station. 4) Turn the power back on and restart the machine. If the folder still doesn't start, check the jam switch, fuses or drive button contacts. If the feeder is not working, check the double sheet detector, fuses or feed button contacts. If the first station started and/or fed properly, plug in the next units one at a time using the blind/dummy plug to find which station or delivery is causing the problem. Then check connections in plugs, fuses, jam switches and button

The Prinance Print Management System from Heidelberg is a fully functional and easy to use system for estimating and quoting jobs, generating job tickets, managing inventory, collecting production data, and other important functions. Prinance can generate new estimates from a previous estimate or template in five easy steps: • After launching, click on “Order Archive.” • In the bottom-left area of the screen, select “Find” and then select the estimate (labeled ES) that you wish to use as a “template.” • From the menu bar, select “Estimating - Copy”; the “Copying a Transaction” window opens and automatically assigns a new estimate number (which can be overwritten

The criterion for choosing between computer to plate (CTP) systems with violet laser diodes and those with thermal laser diodes is anticipated run length. Unlike thermal plates, silver halide plates for violet technology cannot be post-baked for extended life and thus will run to a maximum of about 350,000 impressions. Violet-sensitive photopolymer plates can be post-baked for runs of one million impressions or more, but their resolution is lower than that of silver halide plates. In terms of print behavior—clean running of the plate, ink/water balance, ink feed, dot gain—and achievable print quality, there is no real difference between violet and thermal technology. Plate throughput

Ink for perfecting has special performance requirements. For instance, to avoid smearing after sheet reversal, the ink of the first impression behind the perfector must not build up on the impression cylinders of the following printing units. To achieve this, the ink must be shorter—less viscous or “flowable”—than normal. Ink manufacturers offer inks especially for perfecting, but if these are not available, the ink can be set short by adding 3% to 5% printing oil. Linseed oil-based additives are particularly recommended because they prevent drying and reduce the ink build-up on the downstream impression cylinders. A short-set ink also reduces trailing of the paper

When running polyester plates on a Printmaster GTO 52 with a direct continuous dampening unit, do not thin the ink with print oil or other additives. Keep the water pan spotless so that no grease gets onto the plate. The dampening system’s pH value should be about 5. (Important: do not add alcohol.) To avoid overstretching the plate during mounting, tighten the tensioning nuts only by hand. Compression between the blanket and the plate cylinders must not exceed .1 mm. Before production, polyester plates must be treated with the sponge-on etching solution recommended by the manufacturer. If printing is interrupted, more etching solution should be

The best way to accurately reproduce a colored paper stock on a proofing device such as the HP 5000 inkjet proofer available from Heidelberg is to create a new target (press) ICC profile using the PrintOpen module of Prinect Profile Toolbox. First, print test patches for PrintOpen using the colored paper to be reproduced on the proofer. Read the values into PrintOpen using a spectrophotometer, and PrintOpen will create a target profile from this data. A quicker but less accurate solution is to bring the existing target profile into PrintOpen for editing. Using a spectrophotometer, read the LAB values from the colored paper to

The best time to make a quality check of printed sheets is either immediately before or during jogging. At this stage, crumpled sheets can easily be sorted out, and the appearance of the remaining sheets can be examined. The sheets also can be checked for even positioning by looking at the cutting marks printed on them. By turning the sheets over while fanning them out, the operator can also detect sheets that have been positioned in the press with their sides incorrectly aligned. Sheets displaying dirty edges because of misalignment can then be removed from the pile. Using a stacklift that can be adjusted to the

KENNESAW, GA—09/26/2006—Heidelberg will introduce its Stitchmaster ST 450 saddlestitcher to the North American market at Heidelberg booth #1200 at Graph Expo 2006. The new saddlestitcher is designed to meet market needs, fusing high performance with reliable quality at speeds up to 14,000 cycles per hour. “The Stitchmaster ST 450 opens up new possibilities for saddlestitching by delivering greater productivity, increased flexibility and the ability to handle a broad range of applications,” said Ralph Pasquariello, vice president, Postpress Product Management. “The combination of high speed and quick, automated makereadies enables customers to produce a wide variety of high-quality short- and long-run jobs economically, while

KENNESAW, GA—September 20, 2006—Following the success of its systemservice 36plus program announced at PRINT 05, Heidelberg will establish the next milestone in service offerings with the unveiling of its new Partner Program at Graph Expo 2006. Show attendees can learn more about Heidelberg’s new service offerings in the systemservicearea of Heidelberg’s booth #1200 at the tradeshow, which is being held in Chicago at McCormick Place on Oct. 15-18. The Heidelberg Partner Program is a suite of 20 customized services that provides customers with the flexibility to select the services that best meet their needs. With the new program, customers can build their own service plan

KENNESAW, GA—09/12/2006—For the first time in the U.S., Heidelberg will showcase Anicolor, the world’s first zoneless short inking unit with dampening system, at Graph Expo 2006. An option on Heidelberg’s Speedmaster SM 52 line of presses, this unit, which has no ink zones, makes it possible to produce even the shortest runs using a standard offset workflow with significantly higher margins. Anicolor will be available for all four-color models of the Speedmaster SM 52 starting in the fall of 2007. Show attendees can view a Speedmaster SM 52 Anicolor press at Heidelberg booth # 1200 at the tradeshow, which is being held in Chicago
