It seems like what you are asking is to interpolate from 96 dpi to 300 dpi. Fundamentally this is impossible, as you are always creating data from nothing. If you had the actual timeseries, you could choose to make some assumptions about the signal and interpolate using some rational choice for basic functions. <br>
<br>
You do not say which clinical system you are using. The one I am most familiar with is Natus Xltek hardware with NeuroWorks software. With this system you can print pages of EEG to a printer and achieve higher resolution than you can get from a screen shot, probably 600 dpi, or possibly more. It is also probably the case that you can "print" to a PDF file that would retain high resolution, which you cold check by creating the PDF file first, then printing it.<br>
<br>
If I were you, I would export the raw EEG data (most systems can export as EDF format, or ASCII in a pinch) and then use Matlab of other software to create the EEG plot you need.<br>

Subject: [EXTERNAL] [Eeglablist] How to obtain a clinical EEG for publication (photoshop?)<br>
<br>
This email originated from outside of Legacy Health. Please use CAUTION when clicking on links or opening documents.<br>
<br>
Dear all,<br>
<br>
Does anyone know how to produce a high-resolution (300 dpi) version of a clinical EEG obtained from a screenshot?<br>
<br>
Screenshots have maximally 96 dpi, and when they are increased to poster size they are shaky and the EEG lines become pixelled like stairs...<br>
<br>
Is there anyone who could direct us how to convert this screenshot into a<br>
300 dpi publishable image with smooth lines? Photosphop?<br>
<br>
Thanks in advance,<br>
Markus<br>
