Greetings,
I am a narrow web flexo printer and need some advice on profiling targets. I am presently using IDEALink and the G7 methodology to set up the proper curves for a number of our locations. Most of the presses I will be working with have a 10" wide web. I really like the ECI2002 random target and have printed some in the past experiments.
The only problem with this target is that it takes up most of my available web real estate, leaves almost no room for images and I can only read it in spot mode using my iO. Reading in spot mode takes almost 1 hour to read 1 target and I will be reading a minimum of 20 targets per press for each of the 8 presses I am trying to profile. I am trying to get all this done before the end of the year including 5 more trips to plants in Texas and Illinois to run and measure linear testing, run and measure G7 curve for accuracy and run the profile target.
The non random ECI2002 target is not an option because of how it formats on our web. Unlike the P2P target the ramps would be running across the web which means they can be dramatically affected by gear marking that we get in Flexo printing. A gear mark in a ramp would render it useless. I am able to mitigate gear mark problems with the P2P by running it with it ramps around the press, placing 2 of them staggered and by running a second run with the plates rotated 180 °. When I measure 10 sheets (20 P2P targets) I get a relatively smooth curve - at least something I can work with.
I am looking for suggestions of another target that is smaller but will give me enough values to make a good profile, or, a way to read the ECI2002 random target in strip mode.
I have checked out all the available targets in MeasureTool and I do not think any will work. I need my target to be on one set of plates - I have found by experience that splitting a target over multiple plants is a sure path to insanity.
Thanks to all that respond.
