Ages ago, the facility used to employ a red coloured painting material. A bright-eye, a dim-wit and a long-face always inspect (team work) the surface after coating. Tiny bubble like imperfections used to be noticed during such inspections but was passed fit for further works.
After some years, the composition of the painting material was changed and had black pigments instead of red. A new dim-wit had joined the inspection team by that time. On one particular occasion, the spray coated surface was having number of spots. The top Boss was called in to show the numerous surface defects.
The experienced dim-wit explained that similar smaller surface defects have been seen with the earlier coating material, but this time, the defects are larger in size.
On hearing this, the Boss impatiently asked “Can you not give a photographic explanation?”
To this the experienced dim-wit replied “Earlier ones were like fish-eyes and now it is polka dots”.
“In the seventies we had fish-eyes and in the nineties they have become polka dots” the Boss concluded and left.
[The narrative though set in a specific environment, could have taken place in a paint manufacturer's unit. This setting helps the reader spin their own yarn :) ]
This episode may referring to phenomenon called "islanding" one often encounters this surface defect as paints dry on soiled surface or otherwise due to ingredients used in manufacture. Nice illustration.kindly tone down the dominance of pict over words!
