This is the way we tell the program how the device chosen for the printing behaves.
Output ICC profile
An output profile contains the information of the printer's usable color space, and of the behaviour of its inks. A wrong output profile will probably render unexpected results in the printed color, so it is very important to select the color profile (or printing outline) according to the combination of material, ink and resolution to be used. A color profile for a printing mode of 720 may not work with a 360 resolution, that is to say, a profile for vinyl may not work for paper, etc.
We can choose one of the profiles to do the printing, although it is possible to add more by using the 'Add…' button. The button on the left will direct you to already saved ICC profiles.
Direct Color Table
If you have any saved color or a selection of them, you can choose them from the drop-down list available in this section.
With the 'Edit' button, you will access a window with the list of special color/s. Here you have the option to import colors to the color table.
When you select one of the colors, the button becomes active, from which you will access the color information window. Here you can eventually change the input and output color parameters which is explained in Special Colors management.
Simulation consists of obtaining in our printer the same results that would be obtained in another printing system. Through several Rendering intents, we specify the color engine what calculations need to be made to transform colors from one color space to another, taking into account both origin and target working spaces.
This program offers various interpretation methods which we will briefly describe below.
Perceptual: The input range is adapted proportionally to that of the output device. This is the most commonly used method for printing photographs, something that does not require great accuracy in color but does require a good appearance.
Saturation: This system aims at obtaining results with more vivid colors, whilst trying not to lose color quality. It works well in vectorial designs that need a certain amount of vividness, or in photographs that are not very saturated, in order to improve their printed appearance.
Relative colorimetric: With this method, if a certain color (CIE L*a*b* value) enters into the range of the device, it is faithfully represented, but with the image still maintaining a good overall appearance. To achieve this, a lineal relationship is established between the black and white of each of the devices (brightness adaptation). So, for example, the white of a monitor directly corresponds to the white of the paper, although they are different CIE L*a*b values. The colors that remain outside the range of the output device adapt to the nearest ones. This can be used for vector and photographic designs, so that the final result "turns out well".
Absolute colorimetric: This method works in a similar way to the relative one, but the brightness is not adapted. In this way, we achieve the most exact reproduction of the input colors. The colors that remain outside the range of the output device adapt to the nearest ones. This is the method to use in corporate logos with few colors, where the best possible color accuracy is essential.
Clean ink: In case the design contains pure colors, as for instance 100% cyan, this will only be printed with cyan ink so the color profile will not "soil" the original cyan color.
Color Matching: Each color of the design is transformed when we apply the color profile according to the indications of the profile. In this way the color deviation which will be obtained, according to the color profile can be calculated, and a search for the color which best matches the real color we want to obtain is carried out. Be aware that the exact colors' search is very slow and the time for processing designs can be considerably extended.
Don't use ICC: no modification is carried out on the entry save for the application of the LUT charts of ink balance that may be already selected.
