Inline Color Control

[JBP]

Has anybody had any experience with Inline Colour Control systems, on either Heidelberg or KBA presses?

Would like to hear of anyones views, good or bad, that have operated with them.

Thanks

You mean Inpress Control (for Heidelberg)? No experience with it, but heard marvelous things about it. If it works as it should, then it definitely should be worth the expense.

excellent on Komori presses

It works very well on Komori presses who keep ink & water very stable.
Not as good with Heidelberg & Alcolor , and even less on KBA's

That is from the field ptractice

In theory - all are EXCELLENT

It depends on the application. Extremely short runs will benefit less than long runs. Single shift operations will benefit less than mutliple shift operations.
They all work well and certainly work better than manual operator settings / adjustments.
There are after market systems available as well as those offered by the manufacturers. I do have a good working relationship with a German manufacturer and have installed systems on KBA's.
Regular inker and dampener upkeep is required for the best results with any system.

Meny - who on earth is this guy - brainwashed , ignorant or just a clown ? Could he possibly get up with any other answer than that Komori is the only functional press on the market. First question, for how long and how many systems has Komori on the market and how many do you think heidelberg has.
Now to the ink and water stability we had a L40 before - hickeys that you couldn´t believe it ink waterbalance poor. We had a customer that we produced magazine covers for - all four up looked different a problem encountered on other presses occasionally, not on every bloody set of plates. On other presses it could be easily solved by changing the oscillation not so on Komori. No scratches no scuffs Komori says - no you cannot print ANY glossy paper on a Komori without marking problem. If you change ICP or sandpaper on the transfercylinders you still have the edge where they start 6cm from the grippers. Then maybe we should mention the photocells at the infeed always indicating failiure all the time, they are so sensitive that we have seen pallets where the paper mills cutter discs obviosly not has been razor sharp thus generating a slight curve on the paper edge, hardly visible to the human eye but it wont feed until we turn the pile. This problem has been on L40, L28 and on LS40 we have now. I clean the photocells more in a week on Komori than I did on the Speedmaster. I´m so fed up with these guys tied to Komori by their navel strings that I simply couldn´t avod give my point of wiev on this matter. I have worked on all kind of presses all have advantages and disadvantages but i´d say Komori definitely has more disadvantages than Heidelberg. From own field practice. cheers guys!

Hi,i'd seen both KBA and HEIDELBERG inpress control and both are good technologies but i would choose the KBA's one as my main reason is that it is not inside the press and for me it is a big advantage.Meny was talking about Alcolor.. if he wanted to say the Anicolor press there is no inpress control but it is a non-conventional press

Meny is ever so slightly pro Komori lol !!

MY OPENMIND-The lithrone G40P is very interesting with his KHS-AI/PQA-S..we wanted to visit komori but it was a question of technical assistance(nearest to us) as the first 5 color press we have was a komori...KBA is the fastest one with his side lay free infeed for me it's my opinion,i can be wrong.ALL have their own advantages and disadvantages ..we are searching for high printing quality,productivity quick make ready..all this are useless without a good PRESSMAN...

Just curious on why its an advantage to have the KBA "inpress" control outside the unit vs Heidelberg Inpress control inside the unit. I also have seen both and feel the KBA version was laughable. To have a device read color that is easily 18 inches from the sheet makes no sense to me. Not only is it 18 inches away, it also much be mounted on top of the coater and must view the sheet through a small crack in the deck plate over the last unit impression cylinder. Heidelbergs is under the last unit deckplate and directly over the impression cylinder reading the sheet at no more than 10mm away. Common sense tells me that the closer you are to the sheet the more accurate of a reading you will get. When reading density with a densitometer you read directly on the sheet, not from an arms length away.

Our visit to both KBA and HEIDELBERG was to choose a press that fit our needs.We made some printings tests and we were able to compare.As I said each has it's own technology but to achieve the same thing-print dots on paper and they did it well.Concerning your question about being an arms length away for the measurements-(MY OPINION) this is the + of KBA as they work hard on it.To be OUT of the press and read all sheets is being (simply but very important) free from "dust/powder"for a measuring device.AND as we are on a open forum I prefer not to talk disadvantages of any manufacturer..hope you understand me..can get in contact if you want

In my opinion, Its an open forum and we all are here to learn from actual user opinion on any kind of equipment. We should openly discuss our experiences. There is no press or equipment that is perfect, all have their own advantages and disadvantages.
