Analysis Modules Viewers are modules that allow the display of colors, profiles, images, spectral curves, reflectance curves, etc ... Currently we have three: - Gamut Viewer - Spectral Viewer - Picture Viewer Gamut Viewer The Gamut Viewer allows you to display in 3D an icc profile, an image, a spot color or a color table to know if your images and colors are reproducible on your print media eg Import file To use the Gamut Viewer, we need to load a compatible file into Coraye.To do so, drag your files directly into the left or right column of the software. Here is the list of files supported by the Gamut Viewer:- RGB or CMYK v2 profiles (.icc, .icm)- Images (.tif, .jpg, .png)- Spotcolors (.spc) - Color table (.cxf , .ase, .aco, .acb, .csv, .table, etc ...) From then on, these files will appear in the left column. To upload files, you can also click “File> Open File” from the menu at the top left of the window. Open the Gamut Viewer module To use the Gamut Viewer, click on the pictogram at the top center. Select the content you want to display To display the gamut of the profile, click on the small square to the right of the profile or the photo. When you select an icc profile, you can see all the information about that profile in the left column. Gamut Viewer only supports ICC version 2 profiles (not version 4) Compare multiple content To compare two profiles or images, simply select them.Here we compare the Adobe RGB profile with a paper profile, to show the colors reproducible by the Epson SC-P7000 printer and EFI proofing paper.The Gamut Viewer shows that it is impossible to reproduce all the colors of the Adobe RGB space on this paper, with this printer (which is normal because no printer can reproduce the Adobe RGB space), but we can have a good idea of the colors that we can reproduce on this paper with this printer. Analyze the content We compare here a jpeg image with a paper profile, to know if we are able to reproduce all the colors of this image on this paper. In this example, the Gamut Viewer indicates that it will be impossible to reproduce very saturated orange and blue colors on this printer with this paper. Here we are comparing a PANTONE color table with the paper profile of an Epson SC-P7000 to see if we are able to reproduce all of the colors in the PANTONE C library.The Gamut Viewer indicates that it will be impossible to reproduce all the colors in this Pantone® color table, but it can be seen that most of them are reproducible. Can we know if the color we captured with a spectrophotometer is reproducible on our printer?The answer is yes.In this situation, we took the example of the PANTONE® 116C from a PANTONE® color chart and compared it to the Epson SC-P7000 paper profile. Gray balance control Coraye's Gamut Viewer can also be very useful for controlling the gray balance of your print.To check if the neutral gray is correct, measure the patches of a grayscale and display them in the Gamut Viewer.You will thus see in the 3D graph whether the gray colors are close to the "L" axis or not.Below, we can see that the grays are a bit bluish, as the gray swatches drift towards blue. Rotate, zoom in, zoom out, move, ... To rotate the Gamut in 3D, you can use the mouse. To move the Gamut in 2D without rotation, you can use the "Control key" and the mouse simultaneously. To zoom + / -, you can scroll with 2 fingers simultaneously on the pad or play with the mouse wheel.For the lucky ones who have a touch screen, have fun with your fingers ... Change transparency You can play with transparency when displaying your gamut, to compare 2 profiles for example.In this example, you can see if the paper profile is able to reproduce black correctly.Absolute black corresponds to the coordinates L = 0, a = 0, and b = 0, so if the gamut of a paper profile reaches or approaches that point, the better your printer and media will be able to reproduce deep blacks. Modify the texture To modify the texture, select Solid or Wireframe in the "Frame Type" option. Use color mode You can change the color of the gamut representation with the “Frame Color” option on the right. For example, we will choose the color white to display the gamut. You can now make full use of the Gamut Viewer. Let's go ! 🔥 Spectral Viewer This module displays spectral and / or reflectance curves.The goal is to check the quality of your light in your cabin to optimize your viewing conditions, for example. How to use Spectral Viewer First, we need to load or capture light samples, or color samples, to display their curves. Start by capturing them: For more information, see the chapter: Controlling an illuminant For more information, see chapter: Capturing a color Or directly load a .sp (light sample) or .spc (color sample) file: The samples will be added in the left column. In the main window of CorayeClick on the "Spectral viewer" pictogram. Then click on the small square to the right of the sample name.The spectral curve will be displayed Example: fluorescent tube lamp. Example: natural daylight Spectral Viewer is also capable of displaying reflectance curves for color samples. The color of the curve is the color corresponding to the color sample. Customize your curves Metamerism By comparing the reflectance curve of a measured color sample with the spectral curve of an illuminant, we can get an idea of what the influence of an illuminant on a color sample will be. (Metamerism)You can also use the cursor on the scale to compare the curves with each other. In colorimetry, metamery is a perception of colors that merge with different spectral power distributions (without correspondence). Colors that correspond to this method are called metamers. When you hover over the curves, you get the values in mW / (m2.nm) Picture Viewer Under development
