DIGITAL EMBOSSING AND CREASING SHEET
A method of printing and embossing a receiver is disclosed. The method includes depositing a pattern of image toner on a side of an image bearing receiver, the image toner including toner particles; fixing the pattern of image toner onto the receiver; depositing an embossing pattern of embossing particles on a face of an embossing sheet or web, the embossing pattern having an embossing-pattern thickness corresponding to a fixed stack height of at least 30% of the thickness of the receiver. The embossed particles have an average diameter greater than diameters of the toner particles. Pressing the image bearing receiver and the embossing sheet or web together in a compliant nip, the first side of the receiver facing the face of the embossing sheet or web, the pressure selected so that with a large enough load so that the embossing pattern permanently deforms the receiver.
1 . A method of printing and embossing a receiver having a thickness, comprising:
a) depositing a pattern of image toner on a first side of an image bearing receiver, the image toner including toner particles;
b) fixing the pattern of image toner onto the image bearing receiver;
c) depositing an embossing pattern of embossing particles on a face of an embossing sheet or web, the embossing pattern having an embossing-pattern thickness corresponding to a fixed stack height of at least 30% of the thickness of the receiver, wherein the embossing particles having average diameters greater than the average diameters of the toner particles of the image toner; and
d) pressing the image bearing receiver and the embossing sheet or web together between a hard nip roller and a compliant nip roller, the first side of the receiver facing the face of the embossing sheet or web, the pressure selected so that with a large enough load so that the embossing pattern permanently deforms the receiver.
2 . The method according to claim 1 wherein the image bearing receiver has two sides, the first side and the second side.
3 . The method according to claim 2 further including pressing the embossing sheet or web against the first side of the image bearing receiver.
4 . The method according to claim 2 further including pressing the embossing sheet or web against the second side of the image bearing receiver.
5 . The method according to claim 1 , wherein the embossing sheet or web includes polyimide, silverized polyester, or stainless steel.
6 . The method according to claim 1 , wherein the diameter of the embossing particles is in the range of 15 to 40 um.
7 . The method according to claim 1 , wherein the embossing particles are toner particles.
