  • a colour profile entails the use of suitable instruments, that are often rather costly, that are not always available to the final user.
  • the profiles can be used that are made available by the manufacturer of the device or by the producers of the colour management software. Above all, for the latter it was, however, practically impossible to manage to provide the colour profiles for all existing devices or even only for most of the colour profiles; further, the first CMS used proprietary formats for the profiles that made them usable only with that specific colour management system.
  • a CMS colour management system
  • the task of CMS colour management systems is to compensate for the differences existing between devices belonging to the same category or to different categories. Substantially, all the CMS resort to a reference colour space that is wider than the space of the single devices used in the processing.
  • a colour management system or CMS is a "translator" of colour space of origin of the image (such as, for example, a scanner, monitor, digital camera) in the colour space of the destination unit, which may be another monitor or a printing unit or the like.
  • the CMS is simply a motor that interprets the profile of a peripheral and "adapts" it or rather converts it, through appropriate operations, to another one.
  • the CMS In order to perform the conversion, the CMS needs information both from the colour space of origin and from the destination colour space.
  • a colour conversion always occurs with the help of two profiles.
  • the RGB values read by a scanner are converted in the CIELAB colour space using the profile of the scanner, and from here in the RGB space of the monitor used for displaying in the CMYK space of the printer that will be used to produce the copies on paper, exploiting for these conversions the profiles of the monitor and printer.
  • the profile of a monitor is a table that, for each numeric triad RGB, provides the absolute coordinates (for example Lab) of the colour produced by this triad whilst the profile of a printer is a table that, for each combination of inks CMYK provides the absolute coordinates (for example Lab) of the colour produced by this combination.
  • the colour management systems can be further used to convert colours on the basis of the characteristics of a printing unit that is different from the one on which printing is taking place.

  • the instrument is connected to the computer and supplies the data to the profiling software that processes the data to produce the profile.
  • the process for making a profile of a printing system thus consists of the following steps : producing a TARGET (i.e. a set of coloured patches) on the item that is selected by means of the specific printing system; measuring the printed target by means of the measuring instrument; using the profiling software to produce, through numerical techniques of interpolation of the measured values, the ICC profile, containing a three-dimensional table (called CLUT) of correspondence between CIE Lab values and the percentages of the inks necessary for producing the equivalent colour (i.e. the so-called recipe) .
  • a TARGET i.e. a set of coloured patches

  • a drawback is that the ICC profile, being the result of an "interpolation", may not be correct. In fact, an interpolation often generates ICC profiles that seem to be correct but in fact produce completely incorrect printing profiles .
  • the drawback is represented by the fact that any printing system produces imprecise results, i.e. the result that is obtained is not uniform and there is no consistency with what is shown on the video and what is actually printed, because the printing process is affected, for example, by the variations of the pigments, the items, the environmental factors such as temperature and humidity and every other factor that varies over time. As a result, the colour displayed on the video then will not be what is actually printed and also the colour produced, once printed, may have alterations compared with the initial colour.
  • the ICC profile indicates the recipe corresponding thereto, even if the recipe is generated by interpolation and in this case is a merely theoretical recipe and it is not possible to know whether the printing result will be actually what is known. Often, for different reasons, the actually printed colour differs, sometimes in a substantial manner, from the colour that indicates the recipe associated therewith.
  • the known art teaches that for a colour that it is desired to print the system provides, owing to the ICC profiles, the recipe corresponding thereto, but once the print is set using that recipe it is by no means certain that the printed colour is the one initially set. In fact, most times the result is very different from the initial result.
  • the present invention resolves the aforesaid technical problems by means of a method for managing colour in a printing process that comprises the following steps: a) providing a recipe, or a preferred percentage of inks,- b) printing by means of a printing device a real colour obtained using said recipe; c) obtaining, through a measuring instrument, the real measure of said at least a real colour printed by said printing device; d) associating with said recipes the real measure of said real colour,- e) setting up an ideal image comprising at least an ideal colour generated by at least a recipe; f) replacing each ideal colour of said image with the corresponding real colour, for example identifying the correspondence between the real colour and the ideal colour.
  • the replacement of the ideal colour with the real colour i.e. the "transformation" of the image from ideal to real may occur automatically, according to what has been defined above or the operator may be asked to confirm, or the operator may have an ideal image devoid of colours and may add the colours, i.e. he may colour it, choosing only between the real colours that are available.
  • each ideal colour is replaced, or is chosen initially by the operator, with the corresponding real colour, i.e. with the colour that will actually be printed by the printing device.
  • the ideal colour is the colour that the graphic processing programme, or the like, has in memory as a colour that should be printed following a precise recipe, i.e. a percentage mixture of the inks.
  • the so-called ideal colour hardly ever reflects the corresponding so-called real colour, i.e. the colour that the printing device actually produces.

  • the invention enables the operator to use a programme containing all the information on the colours actually printed by the printer in such a way as to be able to replace each ideal colour of the original ideal image with the real colours and generate the final image, i.e. the real image corresponding to the image that will actually be printed.

  • the target that is thus produced is measured by a spectrophotometer and the measurements that are thus produced are evaluated to decide if they can be used to create the palette describer or to produce a better target, i.e. a target that produces colours that are more evenly distributed over the gamut of the printer, evaluated in the CIELab colour space.

  • the software obtains, from the values measured in the colour space CIE Lab, the gamut of the printer and subdivides it according to a 3D grid with a set pitch. From the Lab value of each point (intersection) of the grid the percentage of the inks is calculated that are necessary for producing the equivalent colour, using the information on "near" colours. In fact, for each measured colour there exists the "recipe", i.e. the percentages of the inks used. It is therefore an interpolation procedure in the CIE Lab three-dimensional space that produces a new target the colours of which should be evenly distributed inside the gamut of the printer, according to the selected grid.
  • the level 1 target is printed and measured with a spectrophotometer.

In practice, this procedure tends to produce a target the colours of which produce colours that are so distributed in the colour space of the printer as to accurately describe the behaviour.
