Abstract
The invention described herein relates to methods mid systems for printing. More specifically, the present invention provides methods and systems for printing using a disposable substrate containing an essentially dry layer of microcapsules which contain a colorless dye solution in a first substrate region and a substantially dry layer of dye developing compound in a second substrate region. The disposable printing system according to the invention provides a reduced availability for bacterial growth and transfer due to its essentially dry characteristics.
Claims25
A printing system comprising, in combination:
- a first substrate region containing an essentially dry layer comprising a plurality of microcapsules wherein the microcapsules contain a colorless dye solution;
- an image containing device for contact with the microcapsule layer of the substrate, the image containing device having a rigid base, a handle fixedly attached to one surface of the base and an image having a raised portion attached to an opposing surface of the base;
- and
- an image receiving second substrate region for contact with the image containing device wherein the image receiving substrate comprises an substantially dry layer of a dye developing compound.
A disposable ink pad and an image producing system comprising an object having surface relief and a paper or paperboard substrate having printed thereon in a first region on a surface of the substrate an essentially dry layer of microcapsules and binder wherein from about 50 to about 99 percent of the microcapsules by weight is a colorless dye solution for depositing a colorless dye on the object and having printed thereon in a second coplanar region on the surface of the substrate a substantially dry dye developing layer for receiving the colorless dye from the object to produce an image of the object on the substrate in the second region.
A disposable ink pad and an image producing system comprising an object having surface relief and a paper or paperboard substrate having printed thereon in a first region on a surface of the substrate an essentially dry layer of microcapsules containing a dye developing solution for depositing the solution on the object and having printed thereon in a second coplanar region on the surface of the substrate a substantially dry colorless dye layer for receiving the dye developing solution from the object to produce an image of the object on the substrate in the second region, wherein the microcapsules of the microcapsule layer have a spherical diameter within the range of from about 40 to about 80 microns and the dye comprises an electron donating dye.
An image producing system comprising an object having surface relief and a first substrate region comprising an essentially dry layer of fluid filled microcapsules and binder wherein the microcapsules have an average spherical diameter of from about 40 to about 80 microns and contain a fluid selected from the group consisting of colorless dye solutions and dye developing solutions and a second substrate region having printed thereon a substantially dry compound which compound is reactive with the fluid and wherein the compound is printed on the second substrate region in the shape of text or a design which printed compound is substantially imperceptible prior to reaction with the microcapsule fluid and wherein the printed compound becomes visible subsequent to reaction with the microcapsule fluid.
