Printing Method: Dye Sublimation

Our HD Metal Print are first print on transfer paper using Fine Art Inkjet pigments. With a heatpress, the transfer is then vaporized into a special coating on the aluminum. The materials form a permanent bond, making the print extremely robust.

  1. High-quality print, encapsulated in a coating of 7 layers.
  2. Aluminum plate, 1mm thick



With sublimation, the image is diffused by thermal sublimation in the thin layers of polyester varnish previously deposited on rigid supports of a very high flatness. This is one of the major differences with other techniques for transferring or laminating paper prints on metal or plexiglass plates. Here the image « is an integral part of the support » and nothing comes between the work and the eye, the polyester varnish offering a neutral protection of the image, absolutely imperceptible. What’s more, this transparent protection is resistant to fingerprints, scratches, ageing, temperature fluctuations and contact with even the most corrosive products. It is also resistant to direct flame exposure!

This technique therefore requires the use of specific supports prepared in advance: aluminium plates covered with a first layer of pure white substrate, then seven layers of perfectly transparent polyester varnish. The adhesion of these layers to the substrate is total. The image is then written on these plates by contact and hot pressing at more than 200°C of a transfer print on a special paper, with sublimation inks, printers and a RIP* (Raster Image Processor, a computer driver allowing the physical printing of digital image files.) calibrated precisely for this use. To guarantee maximum quality, PIX Fulfillment uses ChromaLuxe plates, the only ones on the market today that provide very high contrast and a wide range of colours. The purity of their white background is exceptional and rivals that of the most neutral papers.

The printing quality must be perfect, as must the uniformity of hot pressing, which is carried out by very large presses. During the passage at high temperature, the inks deposited on the paper pass directly from the solid state (powder) to the gaseous state: it is sublimation. The tiny coloured bubbles thus generated are then trapped in the polyester molecules, which have opened under the effect of heat and gradually close again as they polymerize when they return to the environment. In the end, the colored pigments are encapsulated in a completely waterproof way in extremely resistant transparent varnish beads.


The reproduction requirements of the photographic image are excessively high, and sometimes contradictory:

  • very high number of color shades to be reproduced,
  • respect of the colorimetry desired by the artist,
  • restitution of high contrast values,
  • inversely, rendering the progressiveness of the gradients,
  • resolution of tiny details.
    These requirements are now fully satisfied by this printing process, which guarantees the reproduction of impressive performance:
  • very large colorimetric palette (similar to the sRGB* space, rarely exceeded when printed),
  • contrast among the highest of all pulling dies (useful maximum Dmax > 2.5*),
  • maximum respect of gradients thanks to the use of high-performance RIPs,
  • reproduction of extremely fine details due to the absence of a screen pattern.

Moreover, this printing technique is sufficient in itself for the exhibition of the works. The works produced do not require any particular protection (film, plexiglass or glass) to be exhibited, even outdoors. Because the sublimation process also guarantees – and this is its other superiority – the great insensitivity of the supports to mechanical, thermal and chemical aggression. The ageing of the varnish has practically no effect on the image rendering, whose colorimetry remains very stable over time: no long-term drift, no dulling of colors.

With sublimation, the eye is in direct contact with the reproduced work, now inseparable from this high-end medium that magnifies it, which makes it a work of art in its own right.


Two American research laboratories have conducted environmental tests on photographic prints made with these plates and have clearly established that they are the most durable photographic media on the market.

The first tests were to reproduce the effects of a mixture of incandescent lighting and indirect daylight, and to detect a significant attenuation of colours. The plates were compared to the three best photographic papers available (archival quality): the results show that sublimation reproductions last twice as long as the first two paper references and four times longer than the third.

The second independent laboratory reproduced the effects of fluorescent lighting in an open office environment (no windows). In this test, the plates resisted color attenuation 1.7 times longer than the best paper reference. However, these are papers that are themselves given for a stability of more than a hundred years!

Moreover, our own experience shows no alteration of the supports or colors after a continuous exposure of 3 years outdoors, without any particular protection (plates exposed directly to the bad weather).


The sublimation process imposes high requirements throughout the production line, which remains entirely manual. The prints are therefore made in a traditional way, in accordance with a rigorous procedure that guarantees the accuracy and perfect reproduction of the result:

  • input control of the image to be reproduced (definition, format, colorimetry),
  • checking the entry of the substrate (flatness, cutting, surface finish)
  • for the transfer printing, implementation of a perfectly calibrated printing line,
  • use of specific sublimation inks,
  • use of a special paper that does not absorb inks,
  • meticulous drying of the transfer print,
  • precise application of the transfer on the reproduction medium,
  • hot pressing of the support,
  • print output control,
  • packaging in a secure transport pack.

The production chain is subject to regular controls (consistency of definition characteristics, contrast, colorimetry).
