Why are there 2 different EMBRYON BG?

I just dug out the bg I obtained at least 7 years ago from a game I parted out. The cabinet was waterlogged and smelled so it had to go. The result is I have a bg that has purple hues for the background and the Embryon (spelled out on top of glass) is much bolder in color that the game I have set up. There are differences when compared side by side.

Could someone please tell me the details of why there are 2? I believe DD told me about the purple background and one is more rare than the other. I like the purple and brighter one and it appears to be of much higher definition than the other. So I'm assuming it had something to do with the manufacturing process as to why there are 2? Thanks.

No idea, but it would be cool to see a side by side pic showing the
differences.

How about a side by side detail, and a contest for those willing to find
out which is different in each. Like those children photo things...
Find as many differences? Or is it that bland of a subtly issue and not
worth the fun/effort?

Yes Frank, like in the children's magazine Highlights. Do you remember Goofus and Gallant?

There are 3 versions I know of. Purple hue, Blue hue, and neutral
hue.

Sounds like a linear gradation due to mixing.

Thanks Dave. I guess I have a purple and neutral. I knew you told me about the purple and after reading your answer I now remember you telling me about the blue. I did not know there was a third.

Cody. I'm not sure I understand. If it has to do with the amount of blue ink being applied to the glass then I could see how the colors in the run would look different from the start than at the end of the run. Would all be produced at the same time?

I took another look at them and the best way I can describe the difference is one looks industrial and the other looks like a cartoon. The purple bg has brighter blues, reds and oranges.

Cody:

I read a definition on linear gradient and it appears to be used in web development. Was this process in place over 30 years ago? I would assume the color variation is due to the screening process but again I'm unfamiliar with how back glasses were produced when this game was released. Bally also changed the process from games like Mata Hari to Paragon, Lost World etc. An expanded explanation would be helpful. Thanks.

My response wasn't technical, it was layman. Linear gradation was my best
guess at a term that sounded like what I was trying to suggest. The glasses
were made basically like a T-shirt, if I understand the process correctly.
So different batches of colors were mixed up for each silkscreen. Since the
application of the inks isn't precise, there will be fluctuations in the
fill or density. Then the screens wear as the printing goes on, making some
of the edges fuzzier than others.

This is all speculation on my part and I am not a screen printer.

I too would like to see side-by-sides.

This is what I found as a definition. I get the general idea. Your
explanation of screen wear could answer why the variation.

In order to settle or fuel the discussion I will attempt to take some
pictures when the sun finally shines here in New England. I believe
that will show the side by side differences best.

There are several individuals who reproduce bg that could be helpful
in this post. I'm going to guess that these were not all produced at
the same time and are from different runs. Additionally they might
have changed the blue screen to either punch up or tone down the
colors. Someone has to have an insight on why this occurred. Thanks
Cody.

It's spot color mixed which means that they make up a bit for the day's
work.... then the next day, they make up some more, and even though
there's a formula, there might be some variation because of the way the
colors are mixed.

You know how they always say when you're painting rooms in your house to
take all the cans you get and mix them all together? That's so you get
any color variations out of the paint - even though at the paint store
they're following a formula to make your color - can to can, there's
variations, that would be noticeable.

Now, why they don't do it when they made the backglasses like that
probably comes down to cost.

Although, now that I'm thinking of Embryon, that's probably 4 color
process which is the dots like cody mentioned, unless part of it is spot
color.... Bally did that sometimes. But you get the idea.

This is the pixilated bg. I moved them out of the basement into better light. There is one difference I did not notice before, there is more green and in areas not seen on the other glass. This might explain the deeper blue and purple.

it is seldom you have the ability to compare by side by side.

After thinking about it for a few minutes the green has nothing to do with the purple and blue. Purple is primarily the combination of blue and red. That explains some of the difference.

I posted this because I never saw this amount of variation and difference in a by compared side by side. I have had duplicates of nos glasses for Medusa, Skateball, Bobby Orr, Mata Hari, Hotdoggin, among others so I do have a reference point. Dr Dave told me awhile back about the differences which prompted the inquiry.

Thanks to all. I will attempt to take some pictures and post.

I have 2 backglasses of different origin's. I think the "right" glass is the one with darker blue / purple vs. the one with just purple. My light purple backglass I have is an NOS right from the Bally box so my assumption was it was a second that they removed from the mfg. line because of a defect. Bu after reading this thread I am not sure. It could just be the variation in their process.

I can say the darker one looks better and the lighter purple looks like it is missing some color in the process. So I am wondering if they had a run where they missed some color mix?. That is what it looks like to me. It looks identical the different Stargazer glasses where there some that missed the darker purple / blue color.

I prefer the darker glass in my game vs. the lighter one but they are both fine.

Scott, I think the difference is greater then this type of variation. The 2 versions I have look very different. Too me the press missed a color on one of them or it is so great it was intentional somehow.....

Hope all is well. Do you have Centaur Home ROM's.?

Thanks for backing me up on the different backglasses. I did manage to take a few pictures of mine and will post them. If you have the time take a look at the one that appears to be missing a color. As I stated above it is with the green on the lower part of the bg. Once I get to my pc I will post for all to see.

You were missed on Sunday during the great blackout. Hope things are dry and ok in Texas.

As for WHY they're different, I heard somebody (cant' remember who, but
somebody pin-famous) say once that when things were really rockin' and
rollin, they had several companies providing parts at the same time. So
they honestly could have had 3 different companies making backglasses,
maybe it's just simply they were produced at 3 different places?

I don't think it was always a conscious decision.

Thanks Ron.



No I'm sure it was not intentional. It all starts with the fact that these had a short life of earning in an ops business so quality control was not an issue for them or the manufacturer as long as it made money.

Looks like you have a blue one. The other one I have is even lighter then these. It is effectively light purple. I am thinking now it is probably because other companys were making backglasses at the time to meet demand and it caused ALOT of variation.
