Hello Mr. Patrick,
mapping is not what Im looking for. Im still talking about patch readings only. And no - I dont want to compare 2 or more readings. That gives me info about bad reading appearance but no info how to correct it.
On textile they are a HUGE problem. Until now I havent found a solution/software which can satisfactory read +correct textile measurements. My main problem are: erratic readings, too dark near-white readings, too flat dark readings. And then also a huge non-linearity above 80-90% tone value.
Im after a tool showing patch readings as points connected to curves or to a grid. In this way it is MUCH MUCH easier to identify the irregularities in readings because one can quickly see how the curves are “evolving”. I have some tools for visualizing this in Excel. Unfortunately, Excel is not able to draw real 3D graphs. So Im stuck by 2D cuts (like 0-100/0/0/0 , 0-100/10/0/0, 0-100/20/0/0, etc) which gives me a nice “plane view” for the readings.
It is sufficient for searching most of the bad readings + correcting them… but its time-consuming like hell.
Second, I have found that our textile inks have an very odd gamut shape with strong non-linearity above 80-90% tone value. Profiling software usually cannot handle such bowed curves. Interpolation algos are somehow fooled by that. I would need a 2500+ patches target to get everything right. But on textile that gives me many many wrong/irregular readings. So I decided to go for less readings … and to fill the gaps between them with math…
By manipulating (smoothing out) Lab coordinates of the readings I can get near perfect average Lab positions of the patches. Further Im using Excel to get parameters of perfectly smooth polynomial approximations. Then I use these polynomial curves to calculate all the missing unfeasible patch readings. That gives me wonderfully smooth “pseudo-readings” in the whole gamut. Putting them into profiling software give me fantastic results!! 8)
But going thru one 1200 patches reading and correcting them takes me days !!! I would like to have a tool for quicker and easier visualization.
Is ColorThink able to show line-connection between readings in some preset way?
