A method for producing engineered stone slabs includes depositing a plurality of fragments of composite material into a pile on a surface, which is supported by a supporting structure, and depositing colorant in a predefined region onto at least part of side walls of at least some of the plurality of fragments of the composite material. The method then includes using a press roller to press, flatten and stretch the plurality of fragments of the composite material into a slab, after depositing the colorant.

A method for producing engineered stone slabs includes depositing fragments onto a surface and using a height limiting device to disrupt the fragments so a height of the fragments at the highest point from the supporting structure is substantially the same height as the height limiting device from the supporting structure. The method then includes using a digital printing device, in a first digital printing step, to print an image onto at least part of a top and side walls of at least some of the fragments, and then depositing additional composite material onto at least some of the fragments. The method further includes using a digital printing device, in an additional digital printing step, to print an image onto at least part of the additional damp composite material, and then using a press roller to press, flatten and stretch the fragments into a slab.
