Can someone provide an expert eye as to the differences in color in these two stamps? Is this so common for this series it isn't listed as an error? Image Not Found

re: Color variety?

The stamp on the right most certainly has a darker blue cast. There are many reasons this can happen during the printing process. The most common is a press startup, whereby colors are darker until the pressman has a chance to adjust the colors to where they should be.

re: Color variety?

Michael,

Yes, this is common for issues around this decade.

Once in a while Scott will make a note of things of this sort, such as US #1702 & 1703 (a poor example, but you'll get the idea); usually though, they don't often note these differences unless they are an obvious variation from the norm.

Terry's explanation tells the WHY portion....better than I could have, I might add!

re: Color variety?

Michael, to answer the other half of your questions, "why Scott doesn't list it as an error": because it isn't, or at least not as errors are generally understood and not as errors are defined by Scott.

In this case, you are seeing either a slightly higher or lower percentage of one or more inks. This is just part of the production process. And 4- (or larger-) color process production is notoriously imprecise in minor register and highlights. By that I mean the image is essentially clear and readable; but the colors are inconsistent. Not so much that you would notice without another stamp by its side, but enough that the careful viewer can see it. Except for printers producing art books, this level of pringing is perfectly acceptable. No client is likely to complain to a printer about this level of difference.

I have a large accumulation of the 29c flag over White House in which one can see virutally every possibility for color shift, perf shift, misregistration, etc. It gives a sense of much that is possible. Unfortunately, none is completely lacking the blue or the red; then it would be an error. And would be listed. and would make my heart pitter and patter a little faster.

Hope this helps.

re: Color variety?

Thanks for the responses, interesting, informative and humorous . If Scott lists an error I look for it, no I haven't had any luck so far. If there is a color variation listed I ask my wife to look at it. I don't see the colors blue or green very well. Yes I have been known to wear a green shrit with blue pants on ocassion, not to mention a black and a blue sock.

So to give credit where credit is due I really didn't notice the color difference my wife did.
