Self-plagiarism to re-use figures and key phrases on poster
No, you don't need to start from scratch, and even that might still be self-plagiarism. The proper way is to cite the paper even if it is &quot;to appear&quot;. For a slide presentation, a slide at the end pointing out that the figures come from ... would be enough. It needn't be intrusive. For a literal poster, a footnote at the bottom.
The way to avoid all kinds of plagiarism is to cite. &quot;Paraphrasing&quot; doesn't do the job since plagiarism is about ideas, not their literal expression. If the source is clear and a reader/viewer has a way to obtain the original then you are safe.
