Abstract

Color printers (e.g., laser, solid ink) and copiers produce high quality images. However, these printed images do not show the uniformity of gloss seen with true photographs, nor is gloss as high as seen with conventional photographs. This disclosure describes a modified thermal printer with a simple clear-coat ribbon and low resolution print head. This would be sufficient to apply a cost effective overcoat.

Photoprint Gloss Enhancement

Color printers (e.g., laser, solid ink) and copiers produce high quality images. However, these printed images do not show the uniformity of gloss seen with true photographs, nor is gloss as high as seen with conventional photographs. Currently print engines opt for low-gloss toners, since they are more pleasant for reading text in documents. However, they are not altogether satisfactory for reproducing photographic images. Since higher gloss and gloss uniformity are some of the properties of a true photo that most consumers expect, it is desirable to reproduce them in an affordable manner.

What is envisioned is a modified thermal printer with a simple clear-coat ribbon and low resolution print head.  This would be sufficient to apply a cost effective overcoat. 

A conventional print is made on a laser printer or solid ink printer. The print is then transferred to a modified thermal printer where it is run through a nip with a thermal print head and a clear-coat ribbon.  A clear coating is then applied over the entire print to produce uniform gloss in the final product. Uniform gloss is achieved because the clear-coat is the reflective top-layer in all areas of the final print (I.e., those areas containing no toner, partial toner coverage and full toner coverage). Further, overall gloss is increased across the whole print by use of the clear-coat.

A clear-coat can be applied in several ways. For use in an office setting, it may be most convenie...
