Best folder to use with digitally printed material

[Maxgraphixowner]

Im using Baum 714. Works great BUT when folding 100# coated text if there's alot of coverage it locks up in the folder. I have other jobs done digitally with little coverage that folds fine. If I score it on the Heidleberg before folding it, doesnt help at all. I also have a small Duplo table top folder that it doesnt lock up in but folds crooked with the heavy coverage. These are repeat jobs so I really need to figure an answer for this.... Any ideas? Thanks

Im going in tomorrow and are going to try rubber rejuvinator on the Duplo rubber rollers and see if that helps it fold straighter. Its all I can think of to try?

You might need a creaser folder like a Horizon CRF-362 that die-creases before folding. Here's a used unit in the western US. I think they go for around $40k USD new. Horizon CRF-362 Creaser/Folder - Print & Finishing Solutions

A couple of months ago we took delivery of a new Morgana Digifold Pro XL
Very early days however every job its done so far has been much quicker, easier and more accurate than previously, in fact a pleasure to use.
With coated digital stocks, apart from excessive static, air feed should resolve all the issues that friction feed introduces.
We sold our Duplo DF-1200 folder when the Digifold came, it would experience the same problems the OP describes, particularly with heavier stocks where a buckle folder isn't the right tool for the job. We also offloaded an Autocreaser Pro 33 and similarly, found that pre-creasing heavy stocks before folding on the Duplo, whilst preventing cracking on the fold, didn't encourage registration accuracy to any noticeable degree.

I picked up the Morgan's digifold pro XL also

Had some issues in the beginning with 100lb text trifold and half fold not being consistent but the techs came out and set some pre set jobs for them with some roller and air specific settings and that helped. Not sure if anyone else had those issues.

I also notice that the fold and crease lines done really line up well no matter how much you adjust but it's barely noticeable.

100lb covers up to 16pt is a breeze and joy to use on this machine. 20lb is not rated but still will fold with a bunch of headache misdeeds.

Well its been 3 months and I though Id follow-up on this. My 714 is set up perfectly and folds like it should. BUT, a coated 100# with more than a 50% coverage thru a digital machine, forget about it. Locks up in the folder and what does come out, severely cracked. Tried scoring on the Heidleberg, didnt help much, tried grain short instead of long, no help at all. Gave up and sent to job out.

We are getting a Duplo 648 with a DC Inline folder. It will be for the less than a few thousand jobs. Right now we have a Baum 2020 with an 8 page and a bunch of tri-creasers to handle scoring inline. Full coverage with very, very little cracking and that's only on the darkest colors.

Craig, curious as to how this worked out for you? They quoted me 33k. Love my 648 but boy is that steep. Would be nice not to have to forward to my stahl or morgana unit...

I have the older version of the Challenge 870 Medalist and it runs very well with 100# coated with full coverage. It has the quickset roller gap calipers too. I do score/crease with Tri-Creasers on a Rollem prior to folding and don’t have any cracking issues if the fold plates are set correctly. I run a Xerox Versant, so maybe the toner isn’t as slick as other digital boxes.

Both the Challenge folder and Rollem can be found at a good price used if you want to give them a try. The Tri-Creasers are a bit pricey, but they work very well at eliminating cracking.
