Basic Guidelines for Santander 6 Versions Main version: this version should be prioritized in all communications, from large formats to credit cards. Secondary version: this version is only used when there are size limitations and the main version does not provide enough visual clarity. This is the case in some sponsorship applications. Example: Symbol: the symbol by itself is only used in small spaces where it is not possible to apply the main and secondary versions. This is the case of the app pictogram or promotional elements with space restrictions. Example: Main Version Positive Negative Symbol Secondary Version 1. Logot ype
