Q) Can’t I download a free profile from the internet and achieve the same thing?
A) Profiles are incredibly specific and will only work accurately for that 1 precise combination. So if you can find the exact profile for the media/ink/printer/rip/resolution combination you are using, then that will definitely improve your results.
But what many people overlook is the calibration stage that comes before a profile. Every different printer is slightly different, and to overcome this for best results you should re-calibrate each printer. This can only be done with measurement equipment on your exact printer.
Alternatively HP Designjet printers contain an embedded spectrophotometer and in some workflows will do a “closed loop calibration” where the printer itself will maintain its own internal colour stability. HP call this “Dream Color”
Cielab offer a membership solution called “ColourCLUB” where our customers are given member only access to cielab managed colour profiles to be used in conjunction with HP Designjet printers using Dream Color technology.
