Comment on 2006 Article Plagiarized Three Times in Predatory Journals by Mil Kovasevic

A question to Prof. Beall:
Is it ethical or not, if somebody runs a conference (or conferences) or a journal (or journals) to use as a paper format for his conference(s) / journal(s), the format of a well-known publisher? Do you permit it? Is it OK? For example, can I issue a book in a small printing house using the format of Springer Verlag in the Chapters of the Book. I will report that this paper format is the format of Springer Verlag, but I will not imply at any manner that my book is published or sponsored by Springer Verlag.
Is it ok? If it is not good, I will not do it. I will make other template. Please, advice
