System and method to apply topping materials to print products
Disclosed are systems and methods, including a method that includes depositing a curable adhesive onto a first surface of a substrate in a pre-determined pattern, placing topping material onto the substrate with the deposited adhesive, and applying UV energy to the substrate including the deposited adhesive and the placed topping material to cause curing of the deposited adhesive.
1. A method consisting of:
a. depositing a curable adhesive onto a first surface of a substrate in a pre-determined pattern;
b. placing topping material onto the substrate with the deposited adhesive, said topping material comprising melted powder with solid powder; and
c. applying UV energy to the substrate including the deposited adhesive and the placed topping material to cause curing of the deposited adhesive.
2. The method of claim 1 , wherein depositing the adhesive comprises:
digitally printing the curable adhesive using a digital inkjet.
3. The method of claim 1 , wherein the curable adhesive includes one or more of: a radical type adhesive and a cationic adhesive.
4. A method consisting of:
a. depositing a curable adhesive onto a first surface of a substrate in a pre-determined pattern;
b. placing topping material onto the substrate with the deposited adhesive, said topping material comprising melted powder with solid powder;
c. applying an over-layer of polymer onto a layer of the placed topping material; and
d. applying UV energy to the substrate including the deposited adhesive and the placed topping material to cause curing of the deposited adhesive.
5. The method of claim 4 , wherein the over-layer is applied by a technique selected from the group consisting of digital printing, lamination, silk screening, brushing and rolling.
6. The method of claim 4 , wherein the over-layer is a thermoset that is cured by exposure to the applied UV energy.
7. A method consisting of:
a. depositing a curable adhesive onto a first surface of a substrate in a pre-determined pattern;
b. placing topping material onto the substrate with the deposited adhesive, said topping material comprising a glitter material; and
c. applying UV energy to the substrate including the deposited adhesive and the placed topping material to cause curing of the deposited adhesive.
8. A method consisting of:
a. depositing a curable adhesive onto a first surface of a substrate in a pre-determined pattern;
b. placing topping material onto the substrate with the deposited adhesive, said topping material comprising melted powder with solid powder;
c. applying UV energy to the substrate including the deposited adhesive and the placed topping material to cause curing of the deposited adhesive; and
d. removing excess topping material not adhered to the deposited adhesive by performing one or more of: i) vacuuming the excess topping material, ii) tipping the substrate in order to cause at least some loose non-adhered topping material be removed, and iii) tamping the substrate.
9. A method consisting of:
a. depositing a curable adhesive onto a first surface of a substrate in a pre-determined pattern;
b. removing contaminants by performing one or more of: i) vacuuming the contaminants, ii) tipping the substrate in order to cause at least some of the contaminants to be removed, and iii) tamping the substrate;
c. placing topping material onto the substrate with the deposited adhesive, said topping material comprising melted powder with solid powder; and
d. applying UV energy to the substrate including the deposited adhesive and the placed topping material to cause curing of the deposited adhesive.
