How can I use a Digital Swatch Book to Calibrate an Inkjet Printer.
The ColorShop software has many functions the one's of interest area:
CIE Lab values, Dot area, and Density.
My goal is to send a 21 step swatch with CMYK steps, read each
swatch, determine the density percentage and adjust my RIP.
The problem I have is that when I read it and use the Dot Area tool
the readings are too high ( plus 15-20% ). I just want it to say
that the dot is, for example at 29%, when it should be 25%. That way
I can adjust the RIP by 4 percent. Is this showing me dot gain
values? Has anyone used this spectrophotometer/software for such a
use?
Would I be better using something like ICCTools Pro?
Also, is it possible to use this tool to derive the optimum ink
limiting setting for my RIP and paper combination? My understanding
is that as a colour passes its maximum density it's hue will deviate.
This would be evident in the Lab values, if I understand it correctly.
