Abstract

This idea proposes a method to increase the color accuracy and repeatability in printed 2D and 3D images by applying a white base coat layer under the material used in printing. The base color, roughness, and brightness of substrate media used by customers varies significantly enough to alter the finished image color produced by the translucent materials generally used in printing systems. This base layer would act like an undercoat "primer", resulting in repeatable color fidelity. In the case of a 3D additive printer, the base layer could be flattened to provide a smoother surface finish for the color material.

Base coat to improve color accuracy in a printed object

This idea proposes a method to increase the color accuracy and repeatability in printed 2D and 3D images by applying a white base coat layer under the material used in printing. The base color, roughness, and brightness of substrate media used by customers varies significantly enough to alter the finished image color produced by the translucent materials generally used in printing systems. This base layer would act like an undercoat "primer", resulting in repeatable color fidelity. In the case of a 3D additive printer, the base layer could be flattened to provide a smoother surface finish for the color material.

Conventional 2D prints are generally printed on top of a relatively smooth white substrate.  In some cases, printing may be completed on top of a colored substrate.  In 3D printing, the material used for the bulk of the build may have been chosen for its mechanical properties, and may be clear, black, or any other color.  Customers may want an image printed on the externally visible surface to have similar color fidelity to an image printed on white paper. Existing 3D printers which print images on their outer surfaces use white bulk materials (paper or white powders).

Using this proposal, on a 2D printer, a white toner/ink would be deposited and preferentially spread/fused, prior to development of the CMYK color layers. On a 3D printer, the bulk of the object would be printed with whatever material best meet...
