Digital Information InkZone preset and closed loop




































































 

Press Preset & Closed Loop (inline measurement of colorbar during printing)

InkZone from the Swiss company Digital Information is suited for most types of printing presses, sheetfed and web presses including Heidelberg, Man Roland, Komori and KBA and many other brands.

 

If your company uses ISO 12647 profiles in prepress for outputting jobs, the InkZone preset and closed loop is the perfect match. This is because your printers can select the papertype that your ICC profile is based on before they start printing.

 

The system will automatically ensure that the correct density is maintained during the pressrun, using a feature called "Best Match" - and you can even get ISO Reporting Software built in to print out a report of each run / each job to see for yourself how close your presses are to printing according to the standard.

 

Your printers will love this system as well since it shows them the state of their press, the dotgain for each unit and how close the ink series they are using is to ISO 12647. That will help them to make the necessary changes to achieve the perfect job.

The InkZone workflow - overview

This amazing product is just about the best investment a printer can make. It has a ROI of as little as a few months and has the potential to safe tens of thousands of Euros each year - per press installation.


How much it can safe you is something we can help you calculate using your own input from your operation.

Already have a preset?
If your press(es) already have a preset but it's not really working (takes about as much time for the printers to correct the preset as it would if they had no preset), then it is time for you to replace it. The InkZone preset can be tweaked for as many paper types as you like, as many times as needed to enable correct inking from the start of the run each time.

Already have an inline measuring device on your press(es)?
If your presses already have an inline measuring device but no preset, we can in most cases add the preset and you can continue to use your measuring device.

If your inline measuring instrument does not measure reliably anymore then it may be less expensive for you to get a brand new state of the art InkZone Preset and Closed Loop with Techkon Spectrodrive inline colorbar measurement, than it would cost you to replace parts in your old inline measuring instrument.

Last but not least, where do the density targets used for your inline measuring instrument come from? Do they belong to a standard like the ISO 12647 - or are they just approximate densities set by your printer?

A good Ink Preset is where you safe the most - in the form of paper and time during make ready.

The Closed loop/inline measuring of colorbar during production has the main role of maintaining ink balance during production - which is of course a must if your printing company is working according to a standard like ISO 12647-2 or G7 as an obligation to your customers.

Printers that are interested in having their printing certified according to Ugra or Fogra PSO standard, then it should be noted that an automated colorbar measuring device like the Techkon Spectrodrive with on-screen readings is a condition (an offline version may do but an online/closed loop solution is highly recommended).

If someone told you it was not possible to install preset and closed loop on your press, think again. We have done installations on presses that only had an old cassette player and recorder on it's console to load and safe jobs, so let us at least take a look.

The InkZone system consists of the following components:

 You can add components over time without additional cost apart from installation cost at your own discretion:

 

DI PLOTThe DI PLOT software runs on the workflow server and automatically grabs all ripped files ready for platesetting in the workflow, calculates the inkzone settings from the ripped data and then converts them into CIP4 files that are sent to the InkZone Perfect software running on the press PC.

 

DI PLOT can also be used for printing out a proof from the already ripped data to ensure that layout and content are as they should be - a sort of a blueprint - final check before outputting the job to plate.

 

You can also "Print to PDF" if you prefer not to waste your ink.

The same DI PLOT software can be set up to send data to as many devices as needed, - so this is a one time investment.

InkZone Perfect


This is the Preset software. Here the printer can select the printing form, view it's thumbnail preview and the drop it onto the press (or to the "upper" or "lower" units in the case of web presses). Here the printer also selects the paper profile he wants to use for the job (ISO 12647 standard types or a custom paper profile he has created.

Here, the preset of all ink zones takes about one minute and the presetting should be accurate enough to start printing as soon as the job is in register.

 

This v.s. spending 10 - 15 minutes or more pr. run in pre-adjusting and the re-adjusting the ink zones for all colors, wasting 100-150 sheets of virgin paper or so before printing can begin with an OK SHEET.

 

InkZone PERFECT can be set up to send presetting to up to 3 presses from a centralized hub/PC. In that case you only need the hardware that connects the presses to the InkZone PERFECT PC.

 

IZ MOVE


InkZone MOVE
is a convenient software application that "talks" to InkZone PERFECT. The target density attached to the paper profile in InkZone PERFECT is sent to InkZone MOVE. InkZone MOVE connects to a scanning instrument, such as the Techkon Spectrodrive. The instrument measures both density and LAB of a colorbar on an 8 up sheet in a matter of 12 seconds or so and the density/spectral data along with dotgain, slur etc. is displayed and compared on-screen to the target density. Here the printer can react quickly by making first corrections where the density is way out of target and then adjusting the ink zones where only slight adjustment is required.

 

InkZone MOVE with a single measuring device is available to be set up to measure density for as many as 4 presses.

 

IZ LOOP

InkZone LOOP is yet another software application that "talks" to the MOVE software, checks the target density for the job and compares it to the results of each measurement from MOVE and displays a suggested change to the ink zones for all units of the press on-screen.  InkZone LOOP also comes with a hardware connection from the Press PC to the press. 

Here the printer can select to maintain full control by manually pressing a button to "Approve changes" - or he can set the system to adjust ink automatically right after the IZ LOOP has calculated it's suggested changes in density.


At this stage you have your complete InkZone Closed Loop system set up.

 

Additionally you might want to consider:

 

IZ REPORT

 

InkZone REPORT is the perfect tool for Production and Quality Managers to keep track of how each press doing - how closely it is printing to the target standard. Demanding customers can also be offered to get a printout of their job to see for themselves that the job was in fact printed within his standards.

InkZone Instrument Flight by System Brunner

 

InkZone Instrument Flight, developed by the Swiss company System Brunner not only makes sure that your solids and overprints (C, M, Y, K, CM, CY, MY) as well as your dotgain is in check according to ISO 12647 / PSO / G7. It actually takes advantage of the allowed Delta E and tolerance in dotgain to make subtle adjustments to, for instance, skintones. Here the printer can request the finer halftones to be for instance "slightly more yellow" or "slightly less blue", - and the Instrument Flight will make minor adjustments in the ink density to achieve this, - but still keeping the print within the standard as it's first priority.
