Eric Yes that would work. I still cannot spot what you have described as being variable in the video though - to me it looks like the undulations of a standard CUIM arrangement! The varying ink film thickness from the ink keys would result in some variation in the contact for each segment of...

Green Printer Are you sure that each ductor segment has independently variable timing? This does not appear to be the case in the video and I cannot see how it can be accomplished physically with the arrangement. It actually looks to be exactly like the Baker Perkins C.U.I.M. System. I.e. the...

Ajit 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...

Ghosting on G16 - some comments Ghosting on G16 - some comments Kramer68 This is outside my skill set, but I do know that a lot of work was done in the original design of the Baker Perkins printing units to minimise possible ghosting. There was mathematical modelling of the ink train and...

Steve Having read the discussions here and looked at your video, I am very intrigued by some aspects of QuickSet. If you characterise/fingerprint the Ink Ducts, then how do you cope with variations due to wear, maintenance, calibration, etc.? How can you possibly fingerprint every position of...

Snow leopard file serving issue - a suggestion Snow leopard file serving issue - a suggestion This is not my area of expertise, but strangely I got a similar request for help the other day through a different route. I asked if one of my contacts could help and he replied: It seems that there...

The Esko Web Site says about the Odystar's "Elabaorate Versioning capabilities": "Imagine the cost of paper waste, ink waste and press down time when a plate change required for a different language or version does not exactly match the other plates already on press. Odystar can avoid these...

This is not my field of expertise at all! But I think I remember tinsel foil strips being used on a Web Press hanging from a metal part which was obviously earthed and touching the paper to prevent static problems (probably in the Folder)!

Please explain your question fully. I do not understand what you are asking! The Ink Consumption is obviously calculated from the Ink Coverage required by the printed image. Thanks

I am afraid I do not know about the XL105. But what I do know is that the Duct Roller (or Ink Fountain Roller) Temperature is absolutely critical to consistency of the Printing Process. Erik Nikkanen has already explained why in his post. I believe that the most important thing is to have a...

Does anyone know of an application that will connect to a CIP4/JDF Workflow and write selected Data to a Microsoft Excel Spreadsheet? Or alternatively have some idea of how much time and effort would be involved to write such an Application? Thanks

Guf Actually, I am not up to date with this subject but that is probably the case. As I said, I was involved some time ago and in commercial printing. But I suspect because this did not take off in that market, that it did not happen in the newspaper market as well. Maybe somebody out there...

Guf John is right that the paper is always run the same way through a web press - with the grain parallel to the direction of movement. The difference is in the orientation of the printing plates/pages on the press. For Long Grain the long dimension is around the cylinders and for Short Grain...

Printing Process Printing Process All Okay here are my thoughts from my experience of working on the Software, Systems and Automation of Printing Presses (Newspaper and Commercial) for over 25 years. Most plants invest in major projects for extensions, updates, etc. every 5 to 10 years...

Explanation of numbers for opening of Ink Ducts Explanation of numbers for opening of Ink Ducts Luke I saw your post about your numbers some time ago and have just seen it again and realised that there is a simple explanation. I do not fully understand what your numbers represent - Is it ink...
