Colorant Migration Test

The Test

IPI assesses if the dyes or pigments used to color paper, bleed or transfer to other materials in contact. The test involves soaking the colored paper held in contact with bond paper in distilled water for a certain amount of time. The colorants used for writing, labeling, or printing are tested for bleed, spread, and transfer in a similar way. This test is a requirement for the selection of photo-safe colored paper products and marking materials in accordance to ISO 18902.

All test results are confidential.
