Abstract
A UV ink jet receptive primer is applied by a corrugator to produce a UV ink jet printable, continuous folded, corrugated material, e.g. fan fold. Priming is performed in-line by the corrugator. The primer should withstand the heat, humidity, and abrasion of the corrugator, yielding a surface that can be printed with UV inkjet ink and resulting in a high quality image.
Claims8
A method for processing fan fold corrugated media in a corrugator for ink jet printing, comprising:
- applying a primer to a top liner of a fan fold corrugated media in-line at a primer application station in said corrugator, said primer comprising:
- acrylic colloidal polymer from 5-20%, crosslinking styrenated acrylic emulsion from 10-30%, styrene butadiene polymer from 20-50%, inorganic filler from 0-6%, polymeric wax from 10-15%, additional additives comprising any of defoamers, pH adjusters, and biocide from 2-3%, and a balance of the formula comprising deionized water;
- and
- feeding said primed top liner from the primer application station toward a double backer within said corrugator;
- wherein the primed top layer comprises a printable portion of the fan fold that exits the corrugator.
A corrugator, comprising:
- at an application station in-line in the corrugator, a roller configured to apply a full coverage coat of said primer to said top liner;
- a central impression cylinder configured to support the top liner while said primer is applied thereto by the roller;
- an idler roller configured to guide the top liner;
- triple stack steam drums configured to prepare the liner for glueing and joining of a fluting medium layer of a corrugated construction;
- and
- a double backer in which the primed top liner contacts heating plates under pressure from a ballast belt to form the corrugated structure.
A primer for application to fan fold corrugated media in a corrugator for ink jet printing, said primer comprising:
- acrylic colloidal polymer from 5-20%, crosslinking styrenated acrylic emulsion from 10-30%, styrene butadiene polymer from 20-50%, inorganic filler from 0-6%, polymeric wax from 10-15%, additional additives comprising any of defoamers, pH adjusters, and biocide from 2-3%, and a balance of the formula comprising deionized water.
