The practice of recoloring comics has long been hotly debated. [Can you contextualize this debate further? It must have started relatively recently, since you note that newer technologies are responsible for this. Also, can you quote people who are debating the practice of recoloring comics?] Typically older comics from the 50s through the 80s will be recolored to take advantage of new printing technology. Sometimes, but not always, the original colorist is involved in the recoloring of the work. [This would be a great place to mention specifics: “For example, when Blank Comics decided to release a recolored version of Blank, Somebody was actively involved in the entire process. Commenting on the revised edition, this Somebody said ‘I’m so glad that we have recolored this.’ In contrast, when Amazing Comics rolled out a recolored version of SuperGerbil, Somebody Else posted passionate diatribes about how his original coloring work had been violated. ‘This practice by Amazing Comics is a violation of all that is good and decent,’ he stated.”]
Often the comic will be recolored when it is collected and bound in an absolute or omnibus edition of the work. For example, in the Absolute edition of Sandman by Neil Gaiman, the original colorist Danny Vozzo was heavily involved in updating the comic. (Awesome specificity here. This could be one of the examples you use in the paragraph above. But be sure to cite the reference for this claim, and also try to fold in some actual comments from Vozzo about the process. Also, any critical reception or commentary would be fascinating here.] In the image the color is made brighter and the background characters are individually colored instead of washed in blue. New printing technology also allowed for finer lines and a wider array of colors.
The Killing Joke by Alan Moore was also recolored when the anniversary edition was released. [Who was the original colorist? What did (s)he say? What did Alan Moore say about this? He wasn’t the artist, but he seems to hate almost anything that is done to his work, so I bet you could find a good quote.]
The recoloring of the comic was very controversial [to zombies] because of the significant changes made to the highlighting, costume, skin tone and desaturating the Joker’s flashbacks. In the image the yellow and purple tints are removed from the background in favor of a solid color making the text easier to read. In addition the highlighting on Batman’s suit is changed from purple and blue to simply black as well as removing the yellow background from the symbol on his chest. The comic was recolored to make it appeal to modern audiences and to give it a more gritty feel.
The cover of The X-Men Marvel Masterworks Edition Volume 5 by Arnold Drake demonstrates the true technological advances in printing techniques.
In the original cover the shadows are a deep back hatching and the characters are drawn with thick outlines in the style that was popular at the time. [As with other examples, see if you can find relevant comments from people involved with this or from critics reviewing the book.]
In the updated cover the background has been changed to black and the title was reworked. The shadows on the characters are smoother and seem to blend into the background. In addition the characters in the back are given finer lines to emphasize the artwork.
[Awesome. Need some sort of concluding paragraph here.]
