Ink key presetting

[Prepper]

Hi all,

I'm looking for any info you may be able to supply about a product we saw at Graph Expo 2001. I know its been a long time, but, we were looking at a unit that pulled data from your ripped files and wrote it to a card for use in our Heidleberg press. It was a separate box that did the writing to the card. Best we can remember it was in the range of two to three thousand dollars. I know things have gone up but the closest thing I can find to this now is twenty to thirty thousand dollars to do something similar. We use a Xitron Navigator rip (Harlequin) have no workflow and our press has the old CPC-1? console which did have the tape drive but we upgraded that to a card reader.

Is there any less expensive solutions for smaller shops like us that doesn't involve tens of thousands of dollars?

Thanks,
Terry

This is the company I think you are looking for:

You can try to contact with author of this software:
http://www.excourse.com/presspercent/index.html
He plan upgrade software to write cards for Heidelberg presses.

Re: Ink key presetting

Wayne, I think you're right but what they have to offer now is nearly $30k.

PrepressInterface + Xitron CIP3 plugin?

Re: Ink key presetting

John, our problem with that is our older press console. We have a '89 press that used to be tape drive but we have upgraded that to a card reader, but from what I've been told so far, we still have to have some kind of box or software between the plugin and the console to interpret the CIP3 (ppf?) data into whatever our particular console needs to set the keys?

I'm not really sure on all this, just trying to do some research and see what's possible, so again, any info appreciated.

Thanks,
Terry

Re: Ink key presetting

Ohh, I see now. Probably, you'll need another "box" where you must insert the job cards and write data on them. Have no idea how much it can cost you.

Regular PressPerCent price is $250.

Prinect Prepress Interface works with this card drive:

Terry,

Just sent you a private message.

Re: Ink key presetting

it was a good link Sergey.Our press is old also.i think its worth trying.Reading the literature,it is good for an old press like ours.

Re: Ink key presetting

Ink Ready from Ultimate Technographics will fit the bill.

I just came across the following which might fit the bill:

[http://www.highwater.co.uk/pdfs/InkMonitorConnect.pdf]

It is so new it does not appear in the Products on their Web Site or in their Search!

I found out about it from PrintWeek (this includes some prices and launch information):

I´m not sure if it´s still actual. Try to contact Xitron. They have Keysetter Connect that communicates online with these old CPC consoles. No need to exchange the old tape drive or contact Heidelberg.

There are three critical factors that are required for a presetting system to make the process truly automated. Automated in the sense that adjustments are not required by the operator or a closed loop control system at the start of the run and during the run.

One is to have a positive ink feed that is independent of variables such as water, temperature and press speed.

The second is to have an accurate algorithm that calculates the ink requirements per ink key.

Third is to have an accurate zero setting capability.

Unfortunately, all three of these factors are not addressed properly even on modern offset presses resulting in large errors and variation.

This is an area of great potential to improve the process and potentially the technology to do this is relatively simple and low cost. It is possible due to new science on the subject.

I agree. However in practice we have to do compromises which should help printers reaching ink preset as good as possible even though conditions are not ideal.

Yes an imperfect system is much better than no system.

But the potential is quite great to get this problem under control and solved in practice. Presetting does not require high precision. This can be seen if one examines the ink mileage curves to see the variation in ink volume relative to the print tolerance required. The window is large. The problem is that the equipment and algorithms are not capable but they could be. I am all for developing better technology at lower cost.

This is one of my favourite subjects.

Hi
I came across this thread and last date says 2008! I must inform you that the debate is still very much on and almost all printers from Emerging Nations are looking for this solution of Ink Presetting on older presses. Press percent works on a Mac platform but are there any tested softwares that really work on Windows. Also can anyone help me with the hardware interface with a Komori Litherone that has a card reader?

I am afriad that I cannot directly help you with your questions.

However, I would like to point out that any Ink Presetting system (especially if open loop) needs to be maintained AND optimised. Otherwise any savings initially realised by its use reduce or disappear completely because various operational factors change over time. Similarly Make Ready settings also need to be maintained and optimised.

Please see the following article on my web site which was published in the IPIA (Independent Print Industries Association) journal "Innovation in Print" in November 2010:
http://hdksolutions.co.uk/documents/IPIA_HDK.pdf

Please do make contact if I can be of any assistance with this aspect. I have experience of analysing preset and final ink key settings and hence optimising the various settings and curves use in Ink Presetting Systems.
