PIGMENTS BASED INKS
Epson UltraChrome HDR Inks are pigmented inks with high pigment density, resin coating for more stability, an even surface and gloss, high stability on a wide variety of media including fine art, speciality and plain paper.
These inks use a microcrystal encapsulation technology that is to encapsulate each particle of the pigment in an acrylic resin to form a true protective film shield reinforcing the resistance to light up to 200 years and to increase glossyness of the print.
They have a very wide color gamut with 7to 11 color pigment inks with separate grays for obtaining a wide variety of shades plus 2 black (matte and glossy) and are water resistant.
Machines using these inks are last generation Epson printers (9000 and 11800) having an ultra high resolution (up to 2400 dots/inch). Digital files at the base of my prints are also processed in extremely high resolutions (over 100 million pixels) to ensure clarity of detail and the finest nuances.
FINE ART BARYTA PAPER
Baryta is a special barium sulphate coating that is traditionally applied to a fibre photographic paper base prior to coating with the emulsion layers. The technical benefits of the Baryta layer include greater detail and definition, extended tonal range and excellent archival properties.
The barytas art papers are very high-end papers. Their lasting in time is guaranteed by the manufacturer for 50 to 200 years depending on storage conditions. Barium sulfate (or sometimes titanium oxide) used in their manufacture gives great brightness and protects from ultraviolet over time.
Glossy paper Hahnemühle FineArt Baryta 325 used for my prints Dibond® is an bright-white/high gloss "FineArt" baryta paper, 100% α-cellulose made, slightly textured, slightly warm in tone, 325gr/m2 .
For Premium Prints mounted on DIASEC® is also chose a glossy fiber paper, the Hahnemühle Photo Rag 315 , 315gr/m2, 100% cotton. Smoother and a little cooler than the 325 Baryta. It is Digigraphie® certified.
These two barytas papers are acid-free. Their longevity is enhanced by an alkaline reserve that reduces the effects of the attacks of the atmosphere.
Baryta coated fibre papers have a unique look and feel which have become the standard for fine art photographers worldwide and the one I chose for my prints are probably the most beautiful glossy barytas paper available today (and the most expensive).
