Colorant Bleed Test

The Test

IPI assesses if the dyes or pigments used to color papers and mats, as well as those used for writing, labelling or printing, have the potential to stain neighboring prints. The test involves soaking the colored paper held in contact with bond paper in distilled water for a certain amount of time and observing the manifestation of bleed and/or transfer of colorants. 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 bleed 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 bleed test is a destructive test; sample materials cannot be returned.
