Here's an example: https://imgur.com/X6KwHNm and another: https://imgur.com/nTflKSL
I bought it on sale, but this retails at £40. That's not acceptable. I've bought full colour textbooks with photo quality prints for the same price.
I had a look at a previous purchase, Fluent Python, and it's similar but not as bad. The animal icons (e.g. the ravens with little facts next to them) are still quite poorly printed. I bought that about 6 months ago.
Looking further back in time, I've got some pocket guides to Python and C. It could be a placebo - maybe the paper just feels nicer over time. The printing also looks better, but there aren't any big ink-dense graphics to give a fair comparison:
The first two I bought from Amazon, the latter I bought from Blackwells, but that was years ago. The seller was just Amazon, not a 3rd party.
It is sad because this is not how my older Oreilly books are printed.
I think Amazon should start doing "Verified Sellers" like Twitter does with it's "Verified Accounts".
