Something like this occurs in the shadows area. This is correct in terms of perception by the HVS, because the integration process will merge the blurry viewed black points with the empty spaces between them, creating the corresponding very light tone. Then, when a printer is solicited to build a “slightly different tone of white” in the highlights, the unique way to do that with the only black ink option, is to sparse tiny ink drops. It is easy understood that there are also limits for this combination. Referring to a given printer and its maximum spatial resolution, the number of drops per spatial unit and the intensity of the ink are the two basic principles in the tone building task. The technology employed in the inkjet printers involves a lot of complicated operations which main goal is to emulate the particular tone of each pixel. Printing with the option of only black ink causes in turn two derived problems. This particular property of the inks employed in the photographic quality inkjet printers, has decided some practitioners to recommend the “only black ink” method in order to avoid undesired discontinuities in tones opacity and its corresponding UV blocking capability. Out of this scope are the silver processes that use visible light sources. Even though in the VIS a given tone of gray can be build with several and different combinations of colored inks, its opacity to the UV light can be partially or even completely different. Then, the goal of the ink injected on the surface of translucent media is to block some amount of the UV light used in the exposing step. Conversely, printing life size negatives or positives for alternative processes is intended “to be seen” by ultra-violet light (UV). The blurring provoked by this lack in capability to resolve the ink drops, causes a visual process named integration that in turn, creates a high amount of tone and color combinations in order to emulate the information coming from the pixels of the digital image file.Īs a corollary, all those phenomena belong to the so called visible spectrum (VIS), defined as the part of the electromagnetic spectrum being detectable by the HVS. The second property is that the ink drops must be so tiny that become undetectable in shape and size by the HVS. That is, Black, Magenta, Yellow and Cyan, in addition to some variations as Light Magenta, Light Cyan or Light Black and LightLight Black (grays). A first important property is that all ink drops on the paper are of colors the human visual system (HVS) can detect.

Accordingly, the ink drops dispersed onto the paper surface by the printer injection system have a series of properties related with this visualization needs.

This distinct behavior relating to the same technology applied to suited high quality papers, is related not only with the surface quality of the translucent media, but with the purpose the inkjet print is created for.Ī fine inkjet print created with a photographic quality printer is intended to be seen by observers at a given distance and under a suited illumination. Even applying correction or linearization curves this problem is hardly solved. Both deep shadows and highlights tend to be blocked to some extend. Beyond the discussion about the level of capability to retain the tiny ink drops injected by the printer, those media persist in showing a certain difficult in properly separate the extremes of the tonal range. Nevertheless, when this technology is applied to Pictorico OHP, PermaJet or some other high quality translucent printing media, not always allows for so fine results as expected.

For high end EPSON printers, this is the Ultrachrome Ink Set. A more simple way is the use of the original inks coming with the printer.

Perhaps the Quad Tone Inks for Epson printers by Jon Cone, all related supplies and QTRIP software has been the finest way to inkjet printing a photographic image both ensuring high resolution, the choice of final color cast, the tone gamut and a long lasting if the suited paper is chosen. This technology, sometimes named as Giclé, has been proven as almost equal the continuous tone attributed to the silver and other metals photographic technology. Some of those methods were based on the quickly evolving technology in the area of fine printing on paper. From the early days of digital image printer models to current photographic quality printers, a lot of proposals have been developed. A lot of literature has been written about the best way to inkjet printing life size negatives or positives, both intended for the so called alternative photographic processes.
