stamp imaging trend ...
Hi
When I was working on a catalogue of worldwide trading stamps I had six or seven different color/colour guides and none of them agreed. I ended up using an old Hy-Grade color guide that I think was from H. E. Harris in the 1940s or 50s and best guess. Since many were printed on colored paper and compared under artificial light other people may not agree with my colors. I've had poor results with color copiers at office supply stores. My $99 scanner and $99 ink jet seem to do a better job. I'm using my own set-up when I need a color copy in an exhibit. In a few years when I finish the work on the US Rev-Perfins Catalogue maybe the price of a laser two-sided color printed will be down so I can compare it with ink-jet printers. I would like to redo the trading stamp catalog in color as well as a catalog of US trade union dues and assessment stamps and a catalog of worldwide QSL Bureau stamps. As my doctor said the other day, all these activities keeps you going at 78.

stamp imaging trend ...
a study of GB QVR-GVR reigns was made over the years by a friend in DK
.... he remarks that safe referal point is unused copy ... remarking also the failure of printers to match reality correctly ... water-immersed copies are wildly off-shade ... he developed grading tables for all issues ... gem to junk ... amazing ! from a century of auction house listings and catalogs ... SG as reference point ... I gave up studying GVR issues ... eyestrain regardless of shade, sometimes the indicia carries the collector value ... or market variable |
