What is a Photogravure?

Posted by Fine Rare Prints 09/02/2015 11 Comment(s) Antique Print Tips,

Definition: Photogravure printing is a method of printing high quality images using photographic and etching techniques.


In the early 20th century, some superb artworks were produced using photogravure printing, including the fascinating magnified photographs of plants by Karl Blossfeldt.


Photogravure printing was invented in 1879 and the basic process is to photographically transfer an image to a metal plate, etch the image on the plate then print from it. Photogravure and gravure prints have warm blacks and a charming range of subtle shades of gray.


It is quite easy to identify a photogravure print. Look at the print with a good magnifying glass, and you will see a characteristic honeycomb appearance. This is caused by the grid used in the printing process. The image also appears soft and the dark areas seem pitted, as seen below.

Photogravure is rather a complex process with several variations, but the essence of it is as follows:

1. Photographically transfer the image to a metal plate

This is done by coating a plate with light sensitive gelatin and then exposing it to the light from a photographic image (imagine shining a slide on it). The gelatin hardens most where most light falls, and remains softest where no light falls. So, if the gelatin is exposed to a negative photographic image, the darkest areas of the image will remain softest. These correspond with the lightest areas in the original photo.

2. Lay an extremely fine metal grid on top of the metal plate

This grid remains flat and un-etched in the next step while the square openings can be etched down to different depths according to the hardness of the gelatin.

3. Etch the metal plate with acid

The acid eats away the softest gelatin fastest, so it eats deepest into the metal plate where the gelatin was softest i.e. where it was exposed to least light. So, if the image was a negative, the least light comes from the darkest areas. In the actual photo, these would correspond to the lightest areas.

4. Apply ink to the plate.

Most ink goes into the deepest etched pockets, less into the shallowest. The plate is then wiped to remove surplus ink.

5. Press the printing plate onto paper.

The areas with most ink print darkest. In later years, this step was automated with machines, but in the early days it was done by hand.
If you are interested in photogravure prints, we highly recommend the ones by Karl Blossfeldt.
Nowadays, the process is undergoing something of a revival as computer and laser technology has driven down the cost of producing the metal printing plates. In fact, these machines have opened up many interesting, innovative uses for the process of photogravure, or photo etching as it sometimes called these days.

Hi Glenda, Good question ! It's a bit tricky to advise without seeing a photo of it. You get a feel for how old paper is after looking at antique prints for years so we can usually tell at a glance. One easy tip is if the margins on the paper are quite shiny and white it is likely to be relatively modern therefore more likely to be a reproduction. Another tip is to examine it with a very strong magnifier, and see if it has a similar pattern to the photo above - if it does it is more likely to be a vintage or antique print. All the best Peter P.S. We offer appraisals - see our Customer Service menu at the top.

I have some old printing plates and it seems impossible to find information about them or the book. The top of the plates say munich, 1890 style. The back looks like steel and the front looks cooper. I hope you can help. Thank you for your time.

A good start is to google short bits of text on the plates (if there is any). Also, try searching for the image in Google Images using image search. Also, see our page for appraisals under our Customer Service menu, or athttp://www.finerareprints.com/valuation-of-antique-prints

Hi, came across your blogs while attempting research on prints marked F.A. Inc.; the only mention I found via Google was an antique prints.blogspot, evidently no longer active. I'm specifically researching a Ted Kautzky print; the information on your site tells me it's likely a photogravure by the aforementioned F.A. Inc. Any direction will be most appreciated! Best, Alan
