Gem pictures - shelf print

I am working on a new catalog and need to show colors of the gems we
offer. Is there any off the shelf print quality graphics we can use?
We just need round stones that show a range of precious and
semi-precious colors. Any ideas? James

If you have access to a flat bed scanner, place the stones on the bed
,pu t the cover over and scan. Print the results. You won’t believe
how beaut iful the resulting pictures will be or the detail they will
show. Quality printer assumed.

I recommend that you have a nice heart-to-heart talk with your
printer. Find out what the printer would like you to supply. If you
want REALLY accurate color in the final printed piece, you’ll need his
or her help. One way is to just supply a black and white photo for
position on the artwork and “call out” the end color in a PMS Number.
Pantone Matching System (PMS) is a standard method of describing
color ACCURATELY in the printing industry. David Barzilay, Lord of the
Rings (I used to be a printer in another lifetime.)

Richard, You are right on about scanning jewelry and stones. I have
been using my Plustek scanner for nearly a year now and love it. I
would suggest though, that you can improve the results by building a
box the size of the scanner glass out of 1/2 inch plastic foam sheet
and some white glue. Make it about 1 1/2 inch deep inside so it can be
placed over the item to be scanned. The inside may be lined with
light gray paper or painted etc. This traps the light and produces a
nearly 3D effect. Some of the experts out there might add more to
this for even better results. Cheers from Don at The Charles Belle
Studio in SOFL where simple elegance IS fine jewelry.
