Sunday is blackbag day, so here is my sunday posting:<\/p>\n

Impressioing is still part of my daily routine. I used to open at least one lock per day, now I sometimes skip a few days and open five locks in a row… Occasionally I have to open a lock a different way and take it apart to see why impressioning did not work, but it does not happen often.<\/p>\n

I keep experimenting with new techniques and try to open more sophisticated locks. And I invest a lot of time learning about blanks, and keep searching for exotic<\/a> keyblanks<\/a>. (if you have any interesting european or US blanks, please drop me a mail)<\/p>\n

This weekend I experimented a little on using ultraviolet light<\/a> and UV ink. <\/p>\n

\"impressoning<\/a><\/p>\n

I was hoping ultraviolet light would point out some marks that are difficult to see under normal light conditions. So far this is has not been very successful as I could see approximately 80% of the marks I normally see. And it slows me down as it takes the ink between 45 and 60 seconds to dry. Then again, I just started using this technique … and it is nothing more then an experiment and gaining knowledge and experience.<\/p>\n

I shot some images for my dear readers, so you might want to click on them:<\/p>\n

1) First round of impressioning<\/a> (UV and TL view)
\n2) Second round of impressioning<\/a> (UV and TL view)
\n3) Sixth round of impressioning<\/a> (before and after)
\n4) Marker, includes advice (Edding 8280)<\/a>
\n5) Forensic evidence, ink residue on the lock <\/a><\/p>\n

For this experiment I used a Q22 inspection light<\/a> (UVA light, 360 nm, the least harmful of the ultraviolet spectrum<\/a>) and an edding 8280 marker<\/a>.<\/p>\n
