White Spots on the Stanford Daily
It seemed to me that if the spots had any significance, they would be unique. Now I thought I had seen other spots a few times, but I could not remember. There was only one way to find out. So I commenced the arduous task of closely examining all 1969 Stanford Daily issues, again, this time looking for spots.

I started at the October 31 issue and worked forward. The next issue, Monday November 3, had no spots. Tuesday November 4 was also clean.
On the Wednesday November 5 issue I also found spots on pages three and four that looked similar to the spots from October 31.

Moving on to the November 6 issue there were minor spots on pages 1 and 2.

The November 7 issue again had spots on pages one, and then had the similar spots on pages three and four again. It was becoming apparent that spots on the Daily were not unique at all, in fact, they were a fairly regular occurrence. I began to question my conjecture that a solvent had been used. Perhaps it wasn’t that at all, and instead a printing or scanning defect when the archive was made?

There were no spots for the next five issues. But starting on November 17, I found spots on pages three and four; November 19, pages three and four; November 24, pages three and four; November 26, pages three and four; December 3, pages three and four; and December 5, the last issue of the quarter, on pages five and six.

I looked at the first weeks of issues in January, and there were no spots, so I went back to the October 31 issue, and then worked backwards.
There was a possible spot on the October 30 issue, but it looked like a paste up error on an ad. I marked it as a “maybe.” Then I looked at the October 29, 28, and 27 issues and didn’t see any spots on them. Nor were there any spots in any issue resembling the previous ones going back to September 26, the first issue of the fall 1969 school quarter. There were a couple issues with print degradation, scratches, or letters trailing off with light printing, but there were no spots anywhere near as pronounced as what I had previously found.

I put all this into a new spreadsheet. It was clear that the vast majority of spots occurred on pages three and four, and that almost every time there was a spot, it was always on a Monday, Wednesday, or Friday. There were also unique spots that occurred during this time period, from October 31 to December 5. An examination of the Dailys from the years directly before and after these spots occurred did not uncover any more spots.

All of this aside, I finally realized what many of you likely already have: These spots in the Daily first show up on October 31. The first incidence of these spots is on the Mikado review.

I noted that many of the spots looked similar. But I wondered, just how similar? I imported all the pages into the Photoshop document that held the October 31 pages. When the pages were aligned, there it was, clearly the three-spot pattern was identical, it only varied by what was printed on the page, and by the density of ink. It could also be hidden if it were in the white space of the page, but it was in the exact same location on multiple pages, on both sides of the paper each and every time.

I confirmed that this exact three-spot pattern occurred eight times, from October 31 to December 5. The pattern appeared on pages three and four, seven out of eight times, with the exception being December 5, the final issue of the quarter, where it appeared on page five and six.
This was not someone pouring a solvent on the paper after it was printed. I tried to imagine what would produce what I was seeing. I conjectured it could be a scanning artifact, but why then would it happen on opposite sides of the same sheet of paper, and why only on a few pages? I honestly couldn’t explain what I was seeing by a scanning defect.

A more sound conjecture was that this was a recurring print defect that had to occur at the printer. I called some people who worked on newspaper presses, including G who ran the local newspaper back in Indiana. I knew they had still printed the paper there in the newspaper offices until the early 20th century. G was a family friend, so I gave him a ring.

Upon my description of the spots, G thought that they were likely caused by a crushed blanket—a blanket being a key element in the printing process. Ink was transferred to the blanket, and from the blanket to the paper. And because both sides of the paper would get printed at the same time, a defect on one side showed up on both. G said these were not really “spots” but “blemishes.”

He explained that crushed blankets usually happened when something jammed in the press, like some misfed paper.

“Could someone intentionally damage the blanket?” I asked.

“Yes, you could just touch it with your hand, wearing gloves or using a rag. More likely you would ding it with a hammer, I suppose. It would be quite easy,” G replied.

“Could you intentionally place the damage over a specific article?” I asked.

“Yes, that would be easily accomplished,” answered G.

“And how would one know where to hit the blanket?” I asked.

“Well, you just look. You can see the entire page on the blanket. It’s mirrored, but pressmen all know how to read backwards and even if you don’t, you can see the articles. You would just ding it right on it,” said G.

“Why would the three-spot pattern only occur every once in a while? Why are some issues printed without the spots?” I asked.

G posited a theory: He explained that printers almost certainly had more than one press, and it was vital to keep those presses running as close to 24/7 as possible. Scheduling your time on press is a big deal in printing, especially in the time-sensitive, deadline-oriented printing of newspapers.

He surmised that the press with the crushed blanket was only used when the others, those without the defect, were busy. If there was a print job that was of higher priority, that would get to be run on the good presses, bumping the student newspaper to the press with the defect. The fact that it was always on Monday, Wednesday, or Friday likely meant that there were other jobs of higher priority on those days.
As for not replacing the damaged blanket, it was a time-consuming task, and you might not replace it, if it wasn’t too bad, until you had a significant break in your schedule.

“Like during a slowdown around Christmas?” I asked.

“Exactly,” replied G.

As for the one issue where the 3-spot pattern occurs on pages five and six, G said that was also easily explained—either there was a different pressman on that day who lined up the pages a different way, or the issue might have been special in some way or had more pages than normal, making it arranged on the cylinder differently. I subsequently discovered that this issue indeed had 14 pages, the largest issue of the year.

So, what I have discovered is that the three-spot defect in the Stanford Daily is first seen on October 31, 1969, and it continued on many, but not all, issues until December 5, 1969. It begins on a review of the SF Lamplighter’s production of Mikado with a spot on each of two columns. The occurrences of the blemishes are explained by a crushed blanket on the printing presses, appearing only on days when scheduling at the printing vendor forced the damaged press to be utilized, and not being fixed until sometime after the school term was out, during the Holiday Season.

So, G says this is absolutely a crushed print blanket. Is there any other explanation for these blemishes?

Just curious about why you find this "spot" issue so interesting?
To me, a "spot" is a dark image area.
Your defect is a "hole" in that it is missing the image area, so blank or void.
Next, what printing method was used for this newspaper?
In 1969 it may have been "Letterpress" that used rigid metal or plastic relief plates.
Later, most letterpress was replaced with "Offset Lithography".
Offset uses a soft rubber blanket to transfer ink from the plate to the paper.
If the blanket has a low depression, it will not transfer ink leaving a void or hole.
However, the blanket is a consumable that gets replaced periodically (weeks-month) as it gets "smashed" from a paper jam.
If the defect location stays the same with a new blanket change, then the damage is more severe and probably to the cylinder surface beneath it.
 
I used the term "spots" originally because I was unknowledgeable about the process--they looked like white spots to the untrained eye.
I now understand they are not spots.
These have been confirmed to be printed by offset lithography on a Goss press at Nowell's Publications in Menlo Park, CA.
The reason I am interested in them is I believe the original blemishes, on the Oct. 31, 1969, issue were intentionally made, intentionally placed where they are.
If so, they are evidence that can solve a 50-plus year old mystery.

Ok you peaked my interest, whats the "50 year old mystery" and why do you think they were intentionally made? Was it your add?
I commented on the origional post from a printers perspective, there are reasons to alter blankets for specific jobs but... to damage a press run because of a specific add or article, that's far fetched and risking your job for it.
 
The void defect has a vertical mirror image symmetry, same shapes, same locations.
Did this printer only have one press at that time?
The page numbers are the same (3&4) but the pagination/imposition or form layout could change depending on the number of pages.
Some newspaper presses can print 2 of the same image around the cylinder, it's called collect versus straight. In this case, one of the two images could of had the smashed blanket explaining why the defect appears to come and go, a 50/50% chance of seeing it.
 
If you don't mind, I will reveal the whole thing, but I'd like to ask your opinion on one operational thing before telling you the mystery. Since I have no direct experience with offset lithography, it is critical I get information from people who know.

So here is my question: Is it possible someone could damage the blanket for page 4 (also causing blemishes on page 3), but place this damage so precisely that the mark was exactly aligned (within a line of type or so) over something on page 2? Forgetting the manager, forgetting being fired, is what I'm asking even physically possible?
 
Most web (roll) presses print blanket-blanket perfecting.
Perfecting means both sides of the paper web are printed in a single pass.
Both blankets provide pressure to transfer the ink from the blanket to the paper.
A depression smash (~>0.004") in one blanket can also affect in transfer on the other blanket. A paper (.002") web break can rip/tear, fold-over itself, crease/wrinkle then wrap itself around the blanket and cause the smash.
The rubber blanket with the smash will have a harder, deeper, depression so an obvious void.
The other corresponding blanket which is the other side of the paper web is not smashed but has less pressure to transfer the ink so will have a softer, shallower depression, perhaps still partially transferring a faint, low density image.
If the smashed blanket isn't changed (or temporarily repaired with a swelling paste) it will always be in the SAME location, position and have the SAME size and shape on that same press and deck (station, tower, unit).
The actual page number effected will depend on the imposition or pagination, how they are laid out.
To answer your question, YES, it is possible for a smashed blanket to have the same size, shape, location on 2 different pages.
If running 2 up, out, on, around the cylinder, (collect versus straight) the voids will be every other impression/page. Thats why some press operators also select two (2) samples to evaluate quality, so they don't miss a 50% defect rate.
You can still keep your "secret" from 1969.
 
No I will tell you, I just wanted to see what you would say, given the subject matter.

Put bluntly, if these marks were done intentionally, the marks on the Oct. 31, issue, they were done by the Zodiac Killer, as he would be the only one to know to connect The Mikado and the Zodiac. There are a few coincidences regarding issue, the most important one being the exact placement of the main blemish on page 4 on the Mikado over this letter to the editor on page 2.

My full reasoning and process is in my book:

But if you don't want to spend money I am in the process of posting my evidence and process starting here:

Yep, it always is a conversation-stopper. I understand it is an amazing claim. But I have amazing evidence.
Thank you for the practical information about print blankets.

A pressman contacted me and noted that these blemishes don't look like paper jams at all, and wondered how they occurred. He said crushed blankets look more like creases or a line across the page. What do you think about the shape of these blemishes?
 
It is the item that drops in the press that's determines the shape. Our most recent was a screw, we could make out the individual treads when a solid ink fell where the damage occurred. These look like glue gloobs from a poorly splice web to me.
