Affects Version: 8.2
All the process is the same as usual calibrations. There are some changes you should know, but in fact everything is automated in this version.
1) The first difference will be when setting the inkset. Now you will find we added Fluor inks. We still have Spot colors to use the fluors as we have been doing until now, but also this other option:
2) When Selecting inkset, check the calibration options. If you are using an i1 pro, zebra ruler must be deactivated. The measurement of fluor is only possible without zebra ruler. It is deactivated automatically when selecting a fluor inkset (options.png). Also it is not recommended to use UV filter. Measurements of fluor with UV will be irregular. If you have a material with optical white, we recommend to use a similar one without it to do the calibration.
3) About next steps of calibration, make them as usual, print and measure linearization, choose the black generation, and print and measure target.
4) Before profiling select the profiling presets, with or without OBA (Optical Brightener Agent).
5) After profile, on last step before finishing the process, you will see we automatically select Saturation mode. Keep it like this, we use it to maximize the usage of fluor. Next I will show some examples.
Usage of fluorescent inks ICC
Let’s see some examples on how to play with images in photoshop, and why we use saturation intent.
First I convert to fluor profile already done. If we check the gammut, we can see the areas where fluors will be involved:
Same for yellow and magenta, the maximum usage of the fluor will be in the areas I show in the images. The color need to be one completely in the upper part, and along the light area of yellow and magenta. If we go out this area, more other inks will be mixed. As is known, the more we mix a ink with fluor, the most we loose the fluorescent effect. So as we move off this area, less fluorescence we will have.
Now two examples of the same color, using conversion perceptual (1) as always and saturation (2):
Same color when converting perceptual goes off a little bit from the upper side. This means it will be more mixed with other colors. When using saturation, we force colors to oversaturate, then they are also forced to go to the margins of the gamut. That’s why, without doing any other modification, only sending to print to neoStampa, usage of fluors will be increased.
Another option is do it by yourself in photoshop. Open the image, convert in perceptual if you want, and then play with tools in photoshop to get the colors desired. The good about this, is you will see how fluors colors look in screen, and also you know where they are in color palette, so you can play until finding the perfect color.
