But waterless was supposed to solve all these problems!!!!!!
Looking for help again, we have finally had to resort to using Toyo Aqualess MZ inks on our 52Di press as all other brands have now failed through one reason or another
We have managed to get acceptable results on coated and satin coated stocks but it refuses to run on uncoated stock - we get terrible blotchy or patchy print on the cyan and to a much lesser extent on magenta.
It seems there are no reducers compatible with these inks, we have tried softer blankets and different press temperatures to no effect.
The suppliers have managed to reproduce the effect which is good but getting a resolution is taking too long and jobs are piling up.
Any suggestions, anyone else suffering the woes of waterless print??[/QUOTE
I fully agree, the trouble is that supply industry did not keep up and there really is little support for it in the way of inks etc.
When it works, it is amazing, ...within 15 minutes I can be producing colour matched work
As I said before, if I had my time over again, I would likely buy a Heidelberg SM52-4 standard press.
Interesting. Coincidentally I am just now designing a prototype of my invention for a SM52. Fairly simple design.
There is a chance it might get built and tested. Maybe not.
If run with UV inks, it would probably be able to give the performance you liked with waterless, when waterless worked well.
You are right about the industry not keeping up. If they would have fixed the fundamental problems in the process, they would not have even bothered to develop waterless and other options to avoid actually solving existing problems.
It seems the normal mode of thinking in the printing industry that when they have problems with one method, they go to some new method where they will have a whole new set of problems that they also can't understand and fix. This seems to hold true for the press and for prepress.
Anyhow, I hope you find a solution to you current issues.
If they have problems now Erik, where do we go?
1) Litho? Exclusive question to it.
2) Is Nanography going to be the answer as to the silver bullet?

Toyo lz?
Have you tried TOYO LZ - low tack series? We sell both MZ and LZ but find that the LZ is far more popular. You mention looking at reducer so assume you think tack may be the issue.
Also for some reason some customers find running long grain rather than short grain stock helps against tack.

We have been running a QMDI for the past 6-years and have always had to squeeze the heck out of the sheet when printing on uncoated stock. We run Toyo MZ because the LZ or reduced ink will tone on uncoated for us.
Our biggest problem for the past 2-years or so is trailing edge of solids picking. On coated text weight stocks we have always had to reduce the toyo MZ with reducing fluid in order to get the work off which screws up all of your ink key and sweep settings.
LZ inks have a tendency to tone for us. We have done every imaginable thing to try and fix the picking without reducing the ink and have found no answer. We currently have 5- manufacturers ink in our cabinet, 6-different blanket styles, multiple packing sheets, tried all chiller temp settings, pressroom temp settings, humidity pressroom settings and none have solved our picking problem. We are fully trained on this press and set our rollers properly to both distributer and plates but this is not the problem.
Any feed back is appreciated.
One last thing...Coated "Cover weight" prints just fine it is only coated text weights.
Did you ever figure out a good solution for ink??
