Process for multi-color valley printing and embossing of flooring material and the like and flooring material made by said process

A multicolor valley printed and embossed flooring material and the like made according to a process comprising the steps of:

• applying a plurality of different color inks, respectively to a corresponding plurality of rotatable pattern rolls;
• transferring said different color inks from the pattern rolls to discrete surface areas of a single rotatable embossing and printing roll having a raised surface contour representing a pattern to be embossed and valley printed in a manner such that certain raised areas thereof receive a layer of ink from individual pattern rolls and other raised areas receive overlapping layers of different color inks from at least two different pattern rolls;
• advancing a single sheet of flooring material once into contact with and under pressure of the embossing and printing roll;
• and
• embossing said sheet with the pattern on said embossing and printing roll, and simultaneously printing individual colors in the areas of the sheet contacted by the surface of the embossing and printing roll containing one layer of ink and printing additional blended colors derived from mixing overlapping layers of different color inks under the pressure of the embossing and printing roll in the areas of the sheet contacted by the surface of the embossing and printing roll containing the overlapping layers of different color inks.

• printing a fifth color on the sheet material in the areas thereof contacted by the surface of the roll containing overlapping layers of first and third color inks;
• printing a sixth color on the sheet material in the areas thereof contacted by the surface of the roll containing overlapping layers of second and third color inks;
• and
• printing a seventh color on the sheet material in the areas thereof contacted by the surface of the roll containing overlapping layers of first, second and third color inks.

A process for multicolor valley printing and embossing of flooring material and the like comprising the steps of:

• applying a first color ink to the surface of a first rotatable pattern roll;
• transferring said first color ink from the first pattern roll to discrete surface areas of a single rotatable embossing and printing roll having a raised surface contour representing a pattern to be embossed and valley printed;
• applying a second color ink to the surface of a second rotatable pattern roll;
• transferring said second color ink from the second pattern roll to discrete surface areas of the embossing and printing roll not containing the first color ink and as well as discrete surface areas thereof containing the first color ink;
• advancing a single sheet of flooring material once through a nip defined by the single embossing and printing roll and a rotatable backing roll;
• and
• embossing the flooring material in the nip under the pressure of the embossing and printing roll, and simultaneously valley printing said flooring material with a first color in the areas thereof contacted by the surface of the embossing and printing roll containing the first color ink, with a second color in the areas thereof contacted by the surface of the embossing, and printing roll containing the second color ink, and with a third color derived from blending the first and second color inks under the pressure of the embossing and printing roll in the areas of the flooring material contacted by the surface of the embossing and printing roll containing the overlapping layers of first and second color inks.
