When trying to build a profile with EasyMedia and the following error could occur:
"ERROR CODE 127 i1Prism REPEATED PATCHES HAVE TOO MUCH VARIATION"
In certain ICC targets there are repeat patches (patches with the same value) which are used to check if the consistency of the target is adequate to create a good profile.
If the delta-E between these repeat patches is too high, EasyMedia's i1Prism (color engine to build the profile) will not allow you to continue to build a bad profile.
In a IT8 target there are 29 repeat patches for example, however the TC1617 patches do not as the repeat patches were removed for P2P patches.
For handheld Spectrophotometers like Xrite i1Pro:
- Redo the measurements and when using a handheld Spectrophotometer and make sure to read the correct line with each swipe.
- Reprint the ICC target when visible inconsistencies are observed.
- Try a different target.
- Use a Spectrophotometer with a larger aperture (see below).
- Use double reading found in Setup
For Spectrophotometers which allow aperture change (like Caldera TotalColor LFP or Barbieri Spectro LFP)
- Reprint the ICC target when visible inconsistencies are observed.
- Some media's like textiles require a Spectrophotometer with a larger aperture to increase the sample area and matching target.
- Print a 8mm target and measure with a 6mm aperture.
- Use Contact Less or Slow (Up/Down) mode (Fast will touch the media so is to be avoided for textiles), manual positioning (Allows more control in case of target stretch and blurry auto positioning marks).
- Try a different target.
Other reasons why this problem may occur after the patch measurement:
- The color instrument may have an old lamp in the measuring head and its measurements may no longer be accurate;
- The instrument is not calibrated correctly;
- There is dust or the measuring patch is dirty;
- The measuring patch is not positioned correctly and has changed its position during measurements;
- There missing/failing printhead nozzles that create tonal variations in the same shades;
- There is not a good coupling between the measuring head and the material during measurement, creating inaccurate measurements.
