To evaluate the test chart make sure that the print has dried and - if using textile material - fixated or steamed and washed. For some other media like paper, cutting ink criteria is different. In those, it should be entered the maximum percentage of ink before any irregularities-blurred, stripped, matte, or wet print-appear.
Chart Result A
Ink pre-limiting is not required because neoStampa uses Ink Limit Control with a default cut at 400%.
Chart Result B
Ink pre-limiting is required because the linearization strips are bleeding lower than 400%.
If all of the color-mix patches are bleeding you should first try to find out whether the material is not suited for the inks or the print has been made with a too-high resolution. In the image example, the recommended cut would be between 170% and 175%.
After you can try to limit globally by entering the percentage shown below the first patches that show bleeding on the chart in the 'Ink Limit' field and reprint the chart. It's recommended to try several ink cuts until you reach a reasonable printout that does not require pre-limiting.
