Gary Beals submitted this note on just why auction catalogs are so darned heavy. Thanks! -Editor
Auction catalog weight — it’s not lumber doing that
— its dirt ( Well, OK, clay)
Ever ask yourself: Wait a minute, books are made out of paper and paper is made out of wood. So why is this coin auction catalog heavier
than a similar-sized plank of wood? The reason those beautiful auction catalogs are so darn heavy I learned from my old field of
advertising which involved a lot of coordination with printers: Clay coated paper.
NOTE: I am a new NBS member, and over the last two months I have read every E-Sylum of the last 15 years and seen no mention of
catalog paper weight — thus here you go!
This advertising device I dealt with during more than 25 years as an advertising agency owner. Those wonderful glossy catalogs with
those razor-sharp images are printed on the nicest paper stock for photos which is called coated stock. Coated with what? The coating is
white clay. So you could say that is a type of dirt, or mud or pottery being added to wood pulp and doubling the weight of the basic
paper’s ground wood.
If photographs are just sort-of important, the book can be printed on a nice uncoated stock. But when many millions of dollars worth of
coins and banknotes are being illustrated, only razor-sharp, vibrant reproduction of four-color images will do.
Coated papers have a smooth clay coating applied over the groundwood base paper. The base paper is made first, then put through a bath
of clay coating while running on a machine, followed by calender rollers smoothing out the coating and adding as much as half the weight of
Coated papers are categorized into grades by their brightness and gloss levels, but they all add a lot of weight because of the clay
coating. The coating is finished to a high gloss, or it may be matte, or dull. The most expensive of the coated papers are the heaviest —
and those coin auction companies do not cut corners.
Gary's right - I don't believe we've ever broached this subject in such detail. Thanks for making us smarter about this! That
explains a lot, and it's a good reason never to give up on printed catalogs. That level of image quality is tough to beat, and will
last pretty much forever. Having digital copies on your portable device is nice, but not a complete substitute. -Editor
