publications - Is increasing the DPI of a low resolution image a good idea?


Today after a paper of mine got accepted I received this from the publisher (Elsevier):



We have received the above article for publication, unfortunately figures x1, x2 and x3 are of low resolution and of insufficient quality to reproduce well.


The minimum resolution requirements are 1200 dpi for black and white figures and 300 dpi for colour figures. If you are converting your figures to TIFF files, please ensure that the resolution is correct before scanning them.



The figures are digital 512×512 gray-scale images in the PNG format. The source of the images is not me. I had converted them to EPS files using Inkscape. The source of some of the images is: https://github.com/cszn/DnCNN/tree/master/testsets/Set12.



How do I resolve the issue? Should I just save the same images using 1200 DPI in EPS format and send it to the publisher?
