This error is encountered when you have used a colour of 'Registration' or 'All' within your file.
Solution:
- These colours should never be used unless you are required to provide crop marks (it is recommended to not include crop marks when uploading files to Gelato Globe). Thus avoid the use of Registration or All colours
- This is a common error when using InDesign and there is an easy way to resolve this issue. Manually identify and change all elements of your original design from Registration or All colours to another colour such as Black
