ABSTRACT:
Speckle-patterned paper is produced on the paper machine without the use of printing techniques by first preparing speckle-forming material and then introducing this into a contrasting color papermaking furnish. Paper is then made from the speckle-containing furnish in the normal way. The speckle-forming material is produced either by agglomerating a mixture of papermaking fiber, particulate pigment and, preferably, a latex or other binder or by dry comminution of cellulose fiber aggregates in the form of paper or entangled fiber clumps.
