“Don't make adjustments on a folding machine based on operator frustration. That's the basic rule. If you make an adjustment and it doesn't work then put it back. Too many operators play with the settings and then get completely lost.” — Dave Trutzenbach's Folder Operators Manual (www.partsforfolders.com)
When temperatures fluctuate, so can machine performance. Will Weymouth of Western Trade Printing (Fresno, CA) was running a 4 pt. stock on his Stahl B19 equipped with Tri-Creasers. On Friday afternoon, the job ran fine. Come Monday, however, the folder sheets began ripping immediately, with no changes whatsoever to the folding machine. Running the folder at idle speed, Weymouth aimed a shrink-wrap heat gun at the Tri-Creaser at the insert for 30 seconds. Problem solved!

We say: This is the best use of “four score” since the Gettysburg Address. Hats off to the printer for excellent execution on what obviously was a challenging project!
InfoPrint Solutions Co., a Ricoh company, expanded its inkjet offerings and extended its existing platforms, at Graph Expo 2010. The InfoPrint 5000 family now provides three drop-on-demand engine options:
QuadTech has enhanced its closed-loop Register Guidance System with new automated features.
Automatic fan-out control minimizes register errors due to web stretch. Its development was prompted by the trend toward wider-web presses.
QuadTech's cocking control automatically makes adjustments to realign circumferential register.
An anti-embossing feature automatically enables the dot to print in different locations on the blanket, preventing piling, ghosting and embossing while stabilizing dot gains across the web.
Automatic front-to-back register control precisely aligns the printed image on both surfaces of the web.
Ink guiding senses image positioning and corrects the print-to-slitter register by adjusting the web guide.
