The LAB and CMYK libraries consist of text files that can be updated via the CalderaRIP Spot Color interface, allowing users to add one color and its corresponding value at a time.
However, there is also an option to create a custom library using a text editor or a spreadsheet application, which can then be imported as a text file.
CMYK Library format
Caldera recommends using the following format for a static CMYK library (refer to the description below for creating or editing a dynamic CMYK library):
NNNN: CC.CC MM.MM YY.YY KK.KK
Where:
NNNN = Name of spot color
Example (remember to include the colon after the spot color name):
PANTONE Black 7 C: 84.4 92.3 87.2 0.0
Test: 10.0 20.0 30.0 40.0
You can use Excel to create this file, but ensure that it is saved with spaces as the delimiter.
LAB Library format
NNNN: LL.LL AA.AA BB.BB
Where:
NNNN = Name of spot color
Example (remember to include the colon after the spot color name):
PANTONE 100C: 92.26 -7.93 55.28
Test: 10 20 30
Custom libraries import/export
Once you have created your custom spot color text file with space delimiters, you can import it into CalderaRIP:
Info
Custom LAB libraries must have the ".lab" extension.
When creating a Dynamic CMYK library, importing a text file from a previous setup will not be effective. The Dynamic CMYK library considers the currently selected printer, resolution, media, print mode, and quality. In this case, it first generates a dynamic CMYK library through the Spot Color module and adds a few example spot colors. You can then open the dynamic library file (in XML format) in a text editor or spreadsheet application to add additional colors..
Custom libraries location
After import, the custom library file and the custom dynamic library XML file are saved in a designated location.
CalderaRIP color charts are stored in a folder containing files with *.lab, *.xml, and other extensions. You can access, import, and export these files using your computer's file explorer. However, the specific location path may vary depending on your operating system and software version.
Info
The .cas folder is hidden, so if you cannot find it, please check your hidden file display settings.
For custom spot color mapping, use PDF format, as older file formats like EPS or PS have limitations.
