Hi Everyone, I ran across this block in my collection. I noticed that the chimneys looked different. The chimneys on the left look green and the ones on the right look red or orange. Also, on the left two stamps, the small green tree at the far end of the houses on the right, is almost missing. There is a plainly visible small green tree on the right two stamps. Scott # for this stamp is 1384. My scott Specialized lists some color omitted varieties. Can anyone help me to determine if this is one of those color omitted varieties? Or perhaps a different color omitted? Or just an oddity or freak? At the very least, it is an interesting specimen to look at and compare! I'm new at posting here, but here's a shot at posting a pic of it.  Kind Regards, Dave Norris Oldtriguy <>< |

Color omitted usually means one color was not applied.In my best guess is these are an EFO. Nice flyspecking not many would have caught that! Nice to see you posting here.please show us some more. By the way nice to see a zip block was a big collectable for years.I loved Mr Zip.

Hello Dave, Guess : It has something to do with a portion of the plate, and which colour was ascribed to that portion during the pass. I do not think it is an error, I'd suggest this is a constant. Look at the facade of the rear house at the right hand side, in one location it is ascribed a yellow colour, in the adjacent location, green. Hope that helps. |

The Giori press prints multiple colours from the same engraved plate. It does this with a series of rubber mats (rollers) cut to shape that apply different colours of ink on to the engraved plate. Those rubber mats won't necessarily be dimensionally identical for each stamp's surface and the application of ink on to the plate isn't dimensionally identical either - they're not perfect, they're "close enough". What you're seeing is one of these tiny differences, and that difference then changes the border where one colour changes into another.
Have a close look at the left panel in green ("Christmas") and the brown tree without leaves right beside it. You can see some bleeding of brown ink into the green ink that is larger on some stamps than it is on others. I'm sure if you look close enough with a magnifying glass you would also some some green ink from the text panel bleeding in to the brown tree. This sort of thing is typical of multi-coloured stamps printed on the Giori press.

Ryan is spot on. To be more specific, this stamp was printed on a Huck 9-color Press (which incorporated the Giori). The Huck 9-color Press was notorious for printing freaks.
In your example, the green is not omitted, since the plate color and other green on each stamp can be clearly seen. However, as Ryan noted, ink bleeds/blanks can occur due to the wiping operation or roller shift. It's really problematic on small area spots of ink.
In the left 2 stamps, the "green" that you see is actually supposed to be a dark bottom half of the chimney (shadowing effect). On the other hand, you will see that much (not all) of the green in the trees along the horizon behind and slightly to the right of the house behind the church is missing (compare to the right 2 stamps). Also, in the left 2 stamps, look at the house farthest back at the right -- there are supposed to be some shrubs along the base of the entrance. If you look at the right 2 stamps, it looks like the entire entrance is covered with a green ivy-like plant.
Because of the amount of spoilage, the Huck 9-color Press was not used except for very very large print runs. Eventually, it was completely abandoned in part because of lack of cost effectiveness.

Hi Kim, Would one be correct, to suggest the Huck press can be immediately identified by the "Plate Lines", as shown in Dave's example ? FYI postalmuseum.si.edu/collectinghistory/highlight_7.html |

I edited my post above to clarify that I was referring to the Huck 9-color Press, as Huck produced more than one press.
The line you see is the Huck 9-color Press equivalent of a "joint line", which means it may or may not appear, depending on how much inking occurred. It is not an intentionally designed line on the plate. It may appear for one color or multiple colors. In fact, there is a specialty area that collects different colored or bi-colored joint lines.
The layout of the plate will determine where the line appears (if it does). It is an artifact of the Huck 9-color Press.
But is it a sufficient condition to demonstrate a Huck 9-color Press on a sheet stamp? Sorry, I don't know enough about all the different presses used to give you a reliable answer. Maybe Ryan or someone else can fill in the gap.
The plate blocks of the Huck 9-color Press are a modern plate block specialist's nightmare (or joy) because of the numerous plate numbers and combinations with the selvage slogans -- resulting in 4x the number of usual plate blocks to collect.
