The multi-page "Chronology" and "List of Consuls" tables are scanned images with poor contrast and bad JPEG artifacts. Interestingly, the bottom of the "List of Consuls" table only takes up a few lines at the top of a page and was scanned with significantly higher resolution and better contrast, although the JPEG artifacts are little better. |
I took a look at the List of Consuls in the free sample of the book you mentioned. From what I could see, Amazon is likely to be responsible for the image quality issues that you mentioned in that book. The original version provided by the publisher to Amazon used high quality images.
With Kindle books a lot depends on the device to which the book is being delivered and the format used. I looked at the sample in two different formats, KF8 (azw3) and KFX, both downloaded using Kindle for PC. I compared the total file size of the sample and the size and resolution of the JPEG images that make up the List of Consuls. The images in the KFX version were noticeably clearer with fewer artefacts and are likely closer to what the publisher originally provided.
The KF8 version was 1.4MB and the images were 932x1117 (126KB), 789x1340 (119KB), and 1638x444 (110KB).
The KFX version was 12.3MB and the images were 1252x1500 (1.2MB), 1031x1750 (1.2MB) and 1638x444 (330KB).
