The paper the strip was drawn on was probably closer to a thick, better quality archival paper than newsprint.
Newsprint was more a matter of fact than the ideal form to reproduce them. It had a hard time replicating the crispness of lines(to the point that the style seen in comic strips and books from the newsprint era are specifically drawn for being reproduced on it)- so if you can get it in a better quality than newsprint it helps- especially since most people interested in very old collections like this would want the best quality.
