Colorant Migration 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.
What We Need
For the colorant migration test, the customer shall provide IPI with three 8x10 sheets (or equivalent) of colored paper or enough marking material to cover such sheets.
Please name or code your samples so that we have a reference by which to communicate the test results. Our test reports will refer only to your specific label.
NOTE: The colorant migration test is a destructive test; sample materials cannot be returned.
Materials for testing should be shipped to:
