Lately we've been really struggling on the magenta deck of our 40" with what was seemingly a water control issue. The colour would stay stable whilst the press was cold but the longer you ran for the worse it would get, and by end of shift the metering roller was absolutely filthy. I'm currently...

Machinists = Often as possible to avoid fighting your press for good results. Owner = often as possible to to ensure good returns. This means once a year for operators, once a decade for owners. As a machinist I see the diminishing returns that result from lengthy make readies, reprints and...

Basically any stock: the thicker the stock the more likely you bingle your blankets. They got plenty of sheets in the first unit roller train as well running lighter stocks....

They printer on the '26 got back to me: it was a broken pin that required the side of unit 1 to come off to repair..... sorry I don't have any more technical info lol but it's Christmas and old mate's on holidays too! The problem you're having sounds identical to what he was getting though, we...

Out of curiosity has anyone checked the timing on the feeder?

Our '97 K526 did EXACTLY this.... basically your misfeed detector/sheet dam ain't working properly so a skewed sheet will still get into the press even as the feeder shuts down?? Our engineer fixed this and it wasn't expensive either: he replaced a solenoid and some other minor bits and pieces...

Meh we've been running sans assistants for 2 years now. It certainly affects productivity: having to chase up your stock and strip pallets takes time, the 26" 5 col has to be hand loaded (100k+ sheets in a 12hr shift takes it's toll!) and you lose time every single change over simply due to...

Reduce your ink as much as the press can handle. We find that a couple of Hostmann Steinberg PMS colours tend to do this and reducer seems to be the best solution.

Funnily enough it's not something I even think about when running a job: it's simply part of setting up each and every job as it gets to the press and on long runs keep in mind all the variables that can affect your water film... ambient temp, fountain cooling unit faults (god but I've got to...

Five simple rules regarding running a printing press: 1) balance your ink and water films correctly and you can't go too far wrong. 2) keep impression levels, ink and water levels to a minimum and you minimize headaches. 3) keep calm as you can't think properly angry! 4) there's ALWAYS time...

We've been using HS inks for quite a long time and I must say I'm not a fan. The "Impression" series seemed quite good, but when we finally switched to canisters our local rep seems to be able to source only the "Perfexion" series, and in my opinion it's just too damn light an ink and requires...

To be honest Erik I don't think press technology is going to kill the printing industry, and whilst digital is taking production away from offset I don't believe THAT is the major problem either. What will slowly but surely kill the printing industry (in my opinion) is staring at you right NOW...

That's definately on the cards, looking into flexo, packaging or tin printing. Obviously the basics are similar, it would just be a case of learning the operation of slightly different machinery whilst still being able to lean on the skills I've learnt over the last 20+ years. I'd like to try a...

All of my life I've been involved in the printing trade, I literally grew up in a printing factory and my family has been in the game for several generations (my father believes I'm the 7th generation of printer in our family, traced way back to Germany over 100 years ago). I'm not encouraging...

It's been what.... 2 years since we had this discussion D? Fortunately in that time I could count on one hand the amount of spot colours I've printed since then and PMS 123 has not been one of them ;) My argument hasn't changed with regards to the original issue though: on coated stock or...

We run under blankets on both our 40" and 26" Komori's and I reckon we get a fair amount of dot gain as a result. I haven't got the tools at work to measure the gain, but I've noticed that on higher quality jobs that half tones are hard to get spot on often requiring what I'd consider a fairly...

Akiyamas tend to flog out cam-followers on the impression cylinders without VERY strict maintenance schedules. Often it will manifest as slight doubling of image-especially on lighter stocks. Get them to run some heavier gloss stock (150gsm+) then try lighter and lighter stocks. If you've got a...

So far this shift (3rd day of running new fount) I've put 75,000 on the floor and washed the back cylinders out of habit: they were damn near spotless. Blankets look great all over, the only ink on them is image :) temperature is currently 36.5 degrees C, and aside from a technotrans that's...

We've just seen excellent results in a change in fountain solution here... We run in an un-air-conditioned pressroom, and as summer approaches here in Brisbane we are seeing pressroom temps ranging between 20 to 38 degrees C, and if this summer is like all the previous ones I've worked here...
