Spotify in callas pdfToolbox
Spotify features are available in the following ways:
- as an action, which works in the same way as the fixup, but offers access only to the two most relevant parameters and thus is easier to use
- as a fixup, with access to most parameters that can be configured
- as an inspection tool, with access to most parameters, offering a way to play around with the parameters in an ad hoc manner and immediately see the effect of each parameter
- for command line versions of pdfToolbox in the form of a specific Spotify mode (providing access to the complete set of Spotify parameters)
The description of the various parameter available in the different ways Spotify may be used are available in a separate article Spotify parameters.
You can find Spotify action in Switchboard under the category 'Prepress'.
By default, we use 'CSS Color Module Level 4' as the spot color library. More info like the list of web colors here. You can select spot color library to use for Spotify action using the dropdown as shown below.
Set up your own spot color libraries by clicking on the options icon on the bottom left of the Switchboard window and then selecting 'Managing spot color libraries'.
You can copy your own color libraries in 'SpotColorLibraries' folder (for example ASE files exported from Adobe Photoshop as in the next screenshot).
ACO (Adobe color file) and ASE (Adobe Swatch Exchange) files can be exported from Adobe products like Photoshop. These formats makes it easy to share colors between programs.
Also, a file with the ACB file extension is an Adobe Photoshop Color Book file. They're used to provide an easy way to comply with particular color standards, like for if you're printing an image versus using it for on-screen purposes.
You can edit the spot color libraries (in json format) that are found under:
C:\Users\admin\AppData\Roaming\callas software\callas pdfToolbox 11\Repositories\Custom\20200622_145335\SpotColorLibraries
Color components in ASE files are stored using float values, for instance in RGB component values goes from 0 to 1 (instead of 0 to 255). For RGB and Gray colors, an convenient hex field with the HTML hex color format is included.
RGB + L (Lab) values are from 0 to 1
a, b from Lab values are from -127 to 128
To use Spotify in a Fixup, you can either create a new Fixup or edit an already existing Fixup. Find Spotify as the type of Fixup (under Fixup category 'Color spaces, spot colors, inks').
You can select spot color library to use for Spotify Fixup using the dropdown as shown below.
You can copy your own color libraries in 'SpotColorLibraries' folder (for example ASE files exported from Adobe Photoshop as explained above).
