Now, many bromoilists are plagued with dreaded **white spots.**
These are large (up about about half the size of a dime) spots that will not accept ink -- period. What causes them? From the best that I have been able to tell it's uneven coating of the gelatin in the manufacture of the paper.
I have had them with Chen Fu and Agfa MCC 118 papers. Usually
Maija says the solution is several coats of spray starch on the back of the paper, letting each coat dry before applying the next.
I have seen these spots on several other papers, always the
same sort of
by the way, also never found a remedy once they appear except the scissors....
Have continued my research on white spots. They seem to come up quickly, first or second soaking. You can see them if you hold the print/matrix up close to a light when it is soaked. I saved two yesterday in this manner. After the discovery of said spots, I stopped inking and with a paper towel soaked in naptha, cleared the matrix of ink (a light grey image remains) then with a clean towel and a little naptha, wiped the back of the matrix. Before I let it dry , I cleaned the matrix with a wet (water) sponge, patted it dry then let it dry over night. The next morning I super heated the matrix in a dry mount press for a few minutes then cooled to room temp. Inked up with 1803 out of the can with a Dick Blick foam brayer, moved the ink around a bit with the ole brush and I had a print with no spots. I do think you lose some of the white of the paper in this process, but it works, and you don't have to line the trash can with another print. I have saved about ten print out twelve so far. Let me know if you try this, we might be on to something.
As a fresh piece of photographic paper, but from a different pack (and batch), will process normally (with no spots) in the same solutions, we are back to a problem of manufacturing and coating, methinks.
Joe Besse mentioned in Santa Fe that he had experienced problems with white spots. I don't know if he came up with any solutions or not? If so, he never posted them here.
I discussed the dreaded white sopts with Maija. She said that she and other Brit bromoilists had encountered them also on various papers.. Her remedy is to use spray starch on the back of the print to keep the water from migrating through the back side. She said she used several coats of starch, letting each coat throughly dry before applying the next. I tried two coats once and it was a failure. Maija has far more patience than me!
