High-speed inkjet printing for vibrant and crockfast graphics on web materials or end-products

A process for achieving high-speed crockfast process printing on a material with phase-change ink, the process comprising:

• providing at least an array of printheads capable of processing phase-change inks at frequencies of at least about 20 kHz;
• providing a porous material;
• providing a material transport system capable of transporting the material under the printheads;
• providing a plurality of phase-change inks;
• transporting the material under the array of printheads at a speed of at least 1000 ft/mm;
• and
• ejecting ink from at least two of the printheads onto the material so as to form an image;
• wherein the step of ejecting ink forms an image having up to about 200 drops/printhead/linear inch.

A method of creating high-speed multi-color process images, said method comprising:

• providing at least two high operating frequency printheads, said high operating frequency printheads being capable of processing phase-change inks at frequencies of about 20 kHz to about 40 kHz;
• providing at least two phase-change inks;
• providing a substrate;
• activating the printheads such that at least two inks pass therethrough;
• and passing the substrate under the printheads at a rate of at least about 1000 feet per minute;
• wherein at least one process image having up to about 200 drops/printhead/linear inch is formed on the substrate.
