PC42 Pro-100 ICC Profiles
Profiles are created using Argyll CMS and an XRite i1Pro2 Spectrophotometer. All are very high quality profiles and the recommended rendering intent is Relative Colorimetric.
Normally users of ICC profiles would require the use of software like Adobe Photoshop, Lightroom, Photoshop Elements and Aperture or the economical Qimage which all provide colr management. However, the method outlined below will allow the use of ICC profiles without color managed software and is useable on all software.
First check which inks you are using.
In January 2015, the inkset for the Pro-100 was significantly changed and performance was improved a very large degree. Totally new magenta inks were introduced that made the output much more neutral. We recommend ALL users to make this upgrade asap. Here is the link.
We created an upgrade kit to allow current users to move closer to the latest inks. With just the change of three inks, 90% of the latest performance is achieved. The Magenta, PhotoMagenta and Black is changed we called this the PC42R inkset. R as per Retrofit.
The final version is the PC42G. This is different from the PC42G in that very small changes in the gray inks were also changed.

Why Three Profiles for each paper?
The reason is that the standard ICC profile that 99% of users use and are provided by others assume that perfect daylight conditions are what the images will be viewed in. We know that is not always achieved.
Some advanced RIP software can accomodate the changes in light conditons and we provide this similar feature. Black and White images when viewed under tungsten or quartz lights sometimes offer a reddish cast even with the perfect D50 ICC profile. The use of the alternate tungsten illumination profile will sometimes cure this effect. Do realize that the compensation for the different lighting is an approximate guess and can be used when the D50 is displaying strong casts in certain conditions. Only trial and error will determine which one is best used.
The use of the D50 is the normal ICC lighting condition that is normally universally used.
