Method for calibrating specialty color toner
View Patent ↗A method for calibrating specialty toner, the method includes providing a substrate; depositing an invariant or substantially invariant laydown of a color toner on the substrate; depositing a varying laydown of the specialty toner; fusing the color toner and specialty toner to the substrate; measuring a color response signal of the substrate, color toner, and specialty toner; calculating a color response curve as function of the varying laydown of the specialty toner; comparing the color response curve to a target color response curve; and modifying printing parameters of the specialty toner to set the color response curve equal to or substantially equal to the target color response curve.
1. A method for calibrating specialty toner, the method comprising:
providing a substrate;
depositing an invariant or substantially invariant laydown of a color toner on the substrate;
depositing a varying laydown of the specialty toner; wherein the color toner is a complementary color of a primary component of the color of the specialty toner;
fusing the color toner and specialty toner to the substrate;
measuring a color response signal of the substrate, color toner, and specialty toner;
calculating a color response curve as function of the varying laydown of the specialty toner;
comparing the color response curve to a target color response curve; and
modifying printing parameters of the specialty toner to set the color response curve equal to or substantially equal to the target color response curve; and
wherein the specialty toner includes either white, clear, pearlescence, metallic or fluorescent toner.
2. The method according to claim 1 , wherein the modifying printing parameters includes modifying a maximum laydown of the specialty toner.
3. The method according to claim 1 , wherein modifying printing parameters includes modifying a laydown of the specialty toner.
4. The method according claim 1 , wherein the color toner includes either black or any combination of cyan, magenta, yellow or black.
5. A method for calibrating specialty toner, the method comprising:
providing a color substrate;
depositing varying laydown of the specialty toner; wherein the color substrate is a complementary color of a primary component of the color of the specialty toner;
measuring a color signal of the substrate, toner, and specialty toner;
calculating a color response curve as function of the varying laydown of the specialty toner;
comparing the color response curve to a target color response curve; and
modifying printing parameters of the specialty toner to set the color response curve equal to or substantially equal to the target color response curve; and
wherein the specialty toner includes either white, clear, pearlescence, metallic or fluorescent toner.
6. The method according to claim 5 , wherein the modifying printing parameters includes modifying a maximum laydown of the specialty toner.
7. The method according to claim 1 , wherein modifying printing parameters includes modifying a laydown of the specialty toner.
